25 Useful Presentation Topics for Science

By: Author Shrot Katewa

We are mostly asked questions about Presentation Design. But, sometimes, we do have our patrons reaching out to us to seek help with the “content” that needs to be created even before we begin with the design of the presentation.

So, today we are sharing a few really easy-to-cover super useful presentation topics for Science. This is especially helpful for all those teachers and parents who are looking to increase the curiosity of aspiring students and children.

So, let’s dive right into it –

A Quick Note Before We Begin – if you want to make jaw-dropping presentations, I would recommend using one of these Presentation Designs . The best part is – it is only $16.5 a month, but you get to download and use as many presentation designs as you like! I personally use it from time-to-time, and it makes my task of making beautiful presentations really quick and easy!

1. Big Bang Theory – Origin of Our Universe

As a kid, I was always curious about how we came into existence! How the planet Earth was created? How did it all start? This is a great topic to really generate and at times, even quench the curiosity of your students or children. While it is a great topic for presentation in class, it is also an equally good topic for a dinner conversation with your kids.

2. DNA structure

Our DNA is the very core of our life. If the Big Bang Theory is how the universe came into being, DNA is where our personal journey begins. While the structure of DNA is quite fascinating, the impact it has on our lives and how it affects our characteristics is mind-boggling!

It is another great topic for a Science Presentation. Do keep in mind, use of visual aids will most likely improve comprehension and retention among your audience.

3. Gene Editing & Its Uses

In case you choose to go with the previous topic of DNA, Gene Editing serves as a perfect extension of that topic even though it can be a great topic in itself. Sharing insights on Gene Editing and how it works, can showcase the capacity of human endeavors and its resolve to make things better.

4. Important Discoveries of Science

Okay, so this can really be a fun topic. As a kid, it was always fascinating to know about some of the world’s greatest discoveries and inventions.

Be it Penicillium or the first flight by the Wright Brothers, such topics allow you to take your audience on a journey and relive the times in which these discoveries and inventions were made. The thing that I like the most about this topic is that it doesn’t have to be completed in one session.

In fact, this can be turned into a knowledge series of multiple sessions as the list of discoveries is endless.

5. Aerodynamics

Most kids and students are really fascinated with planes. But, only a few really understand the basic principles of how a plane works. Explaining Aerodynamics can be an interesting topic.

It also allows you to introduce props such as a plane and practical exercises such as creating your own plane and analyzing its aerodynamics. The introduction of visuals for such a topic can greatly enhance the learning experience.

So this is a topic that most of the kids and students would have at least heard of, most might know about it a little. But very few would really understand how gravity truly changed our concepts not just on Earth, but also beyond our Planet in our Solar System.

Gravity alone is responsible for the tectonic shift of mindset that the Earth was the center of our Solar System to the fact that the Sun is the center of our Solar System around which the rest of the planets revolve. That and much more!

Explaining the stories of Galileo who first challenged this assumption and how Newton turned everything we knew upside down (almost literally!)

7. Photosynthesis

Another interesting Science topic for a presentation.

How do non-moving organisms produce and consume food? How Photosynthesis is not just limited to trees but virtually drives all lifeforms on Earth through the transfer of energy.

Also, touching upon the fact how Photosynthesis has led to the revolutionary discovery of Solar cells and how it is potentially going to be powering our future.

8. Artificial Intelligence – Boon or Bane

When it comes to Artificial Intelligence, there is a lot that we can do to engage the curiosity of our kids and students. It is an evolving part of Science as we haven’t fully applied and utilized AI.

One of the reasons this can be a great topic is because it engages your students or kids to really think. You may consider forming 2 teams and allowing an open debate on how AI could be a boon or a bane – a great way to promote cross-learning.

9. Ocean – The Unknown World

Our Ocean is what sets our planet Earth apart from the other planets in our solar planet. It is not only one of the main factors contributing to life on earth, the Ocean holds a world of its own with hidden creatures which have only recently been explored.

There is a lot to cover when it comes to the Ocean. Don’t limit your imagination to just lifeforms as you can even talk about treasures troves contained in the ships that sank!

10. Astronomy

So I have a confession to make. Which is this – Astronomy astonished me as a kid, and it amazes me even now! There have been countless nights that I gazed at the stars in the sky in amazement trying to locate a planet, and falling stars and other man-made satellites in the sky.

This is not just an amazing topic for a presentation, but if you could get hold of a telescope for a practical session, it will make a night to remember for the kids and the students!

11. Light and its effects

This is another topic that can turn into a great practical session!

Presentations can be accompanied by a trip to the physics lab or even using equipment like a prism to take the session experience of your audience to a totally different level! Experiencing the various colors that form light is one thing, but understanding how it impacts almost every single thing in our day-to-day activities makes us admire it.

12. Atoms – Building Blocks of Matter

While there is a whole universe outside of our Planet, there is a completely different world that exists when we go granular inside any matter.

There are literally billions and billions of atoms inside just our human body. Each atom has its own world making it as diverse as you can imagine.

How these atoms interact with each other and what makes an atom can be a really engaging topic to bubble the curiosity of the students or your kids!

13. Sound & Waves

Another super interesting presentation topic for Science for kids and students is to understand how Sound works.

There are several things to cover as part of this ranging from simple waves to frequency and resonance experiments. Sound is not just a good topic for a presentation but also for experiments and physical demos.

14. Technology

Technology as a topic has a lot to cover. As we all know that technology touches each of our lives on a daily basis, students can find this topic relatable quite easily. The canvas for exploration and presentation is quite broad giving you a wide range of technology topics to present from.

15. Human Brain

Many believe that we only use 10% of the capacity of our human brain. We have to date only barely managed to understand how our brain works.

Even the parts that we have gathered an understanding about, we don’t quite fully understand. The human brain has remained a topic of astonishment for scientists for a long time. It is only logical to conclude that if presented effectively, this can be a good presentation topic on science.

16. Evolution

When Charles Darwin presented his Theory of Evolution by Natural Selection in his book “The Origin of Species”, it took the world of science by storm.

How the species have evolved over a period of millions of years is quite interesting. There were quite a few interesting learnings that Darwin had and he shared that as a summary. This is something that has been also covered in the TV series Cosmos by Neil Degrasse Tyson.

I highly recommend giving this TV series a watch to get inspiration for some topics for presentation.

17. Magnetism

The majority of the kids have handled and spent hours in awe playing with a magnet. Many try to understand how a magnet really works! But, only a few are able to really understand the science behind it.

Magnetism can be a really fun topic to give a presentation on. Additionally, this topic also allows enough space to display, experiment, and have fun with real magnet and iron filings to showcase the effect of magnetism.

18. Electricity

Electricity is pretty much everywhere.

Today, if there is no electricity, the region is considered underdeveloped or backward. The discovery and the use of electricity is probably one of the greatest inventions of the 20th century.

It has been single-handedly responsible for industrialization, powering growth, and the development of the human race.

19. Steam Engine

Steam Engine was the first step of the human race towards powered locomotives.

From the discovery of the steam engine to how it was responsible for creating a time standard and time zones along with the stories related to it, can all be very fascinating and take you back in time to relive history!

A perfect presentation topic for science students.

20. Science of Medicine

No list of presentation topics for Science would be complete without mentioning medicine and its benefits.

The discovery of medicines and drugs has been responsible for nearly doubling the average human age. The impact is far-reaching with several pros and cons that constitute an interesting topic for presentation.

21. Periodic Table

Students often find this topic very dull. However, if you can help them understand the beauty and significance of this periodic table, it can be an amazing topic.

To really understand how Mendeleev could predict the existence of various elements even before they were discovered, is mind-boggling!

The periodic table is such a perfect table that explains how the elements are arranged in a well-structured manner in nature. This topic can be turned into a very interesting topic but a bit of effort and some out-of-the-box thinking may be required.

22. Buoyancy

Okay, so we all may have heard the story of Archimedes in a bathtub and how he shouted “Eureka” when he managed to solve the problem that was tasked to him. He did this using the Buoyancy principle.

While this story is something we relate to buoyancy the most, there is a lot more than we can truly learn and apply using this principle. This can be a very helpful topic for a presentation as well as a practical science experiment.

23. Health & Nutrition

Health & Nutrition is a very important aspect of our life. Its importance is often not completely understood by kids and students alike. Presenting about Health & Nutrition can go a long way to benefit the students to maintain a very healthy life!

24. Our Solar System

Our Solar System is a topic that is mostly taught since you join the school.

However, while most of us know about our solar system, there are enough mysteries about it to capture and captivate the attention of your audience. Questions like – why is Pluto not a planet anymore?

Or other questions such as – are we alone in this universe or even topics around the Sun as a star or even the asteroid belt between Mars and Jupiter can all lead to great engaging presentations and discussions.

25. Stem Cell

Stem cell research has become cutting-edge medical research. Thus, it is often a hot topic for discussion but is often not completely understood.

This topic will also provide you an opportunity to engage your audience in a debate that could be centered around the ethics of stem cells and their application.

This is a perfect topic as this allows your students or kids to learn and share their opinion with others.

Science is a vast world. Even though there are several other topics that can be covered, we decided to list topics that are relatively common such that it widely applies to a large set of people. If you have shortlisted your presentation topic and are looking for help to create a visually appealing presentation that captures the attention of your audience, be sure to reach out to us!

The field of Materials Science & Engineering is evolving dramatically as we enter the 21st Century. What began as the study of metals and ceramics in the 1960s has broadened in recent years to include semiconductors and soft materials. With this evolution and broadening of the discipline, current research projects span multiple materials classes and build on expertise in many different fields. As a result, current research in Materials Science and Engineering is increasingly defined by materials systems rather than materials classes.

At Cornell, the Department of Materials Science & Engineering (MS&E) has adopted this new systems-based vision of the field by defining four strategic areas which are considered to be critical for today’s emerging research. The four strategic research areas are Energy Production and Storage, Electronics and Photonics, Bioinspired Materials and Systems, and Green Technologies.

Materials Science & Engineering is an exciting and vibrant interdisciplinary research field. Cornell MS&E draws upon its world-class faculty, innovative researchers, state-of-the-art facilities and highly collaborative research environment to respond to challenging technological and societal demands both in the present and the future.

Energy Production and Storage

Energy research will prove to be the most prosperous growth area for the department, the College and the University. The inevitability of an energy crisis and global climate change has intensified efforts in alternative energy research around the world. The excitement building around this sector is reminiscent of the early years of the information technology revolution. Among the many possible sources of alternative energy, the following areas are particularly aligned with the current materials research at Cornell as they play to our existing strengths:  photocatalysis, photovoltaics, thermoelectrics, phononics, batteries  and  supercapacitors .

Relevant Research Areas: 

• Energy Systems
• Advanced Materials Processing
• Materials Synthesis and Processing
• Nanotechnology
• Nonlinear Dynamics
• Polymers and Soft Matter
• Semiconductor Physics and Devices

Electronics & Photonics

The use of semiconductor devices and circuits will continue to play a major role in modern life. Therefore electronics and photonics are considered premier growth areas. As feature sizes decrease, incremental research based on current methods and materials is unlikely to enable Moore's Law to continue. New materials and processing techniques are needed. Advances in nanoscale fabrication have led to recent advances in this field. We have targeted the following areas: oxide semiconductors, 3D integration, materials beyond silicon, high K and low K dielectrics, plasmonics, spintronics, and multiferroics.

• Computational Mechanics
• Computational Solid Mechanics
• Condensed Matter and Material Science
• Surface Science

Bioinspired Materials and Systems

Scientists and engineers are increasingly turning to nature for inspiration. The solutions arrived at by natural selection are often a good starting point in the search for answers to scientific and technical problems. Designing and building bioinspired devices or systems can tell us more about the original animal or plant model. The following areas are particularly aligned with the current materials research at Cornell:  bioinspired composites, engineered protein films for adhesion, lubrication and sensing applications , molecular tools for in-vitro and in-vivo imaging (C-Dots, FRET), as well as biomaterials for tissue engineering and drug delivery.

• Biomedical Engineering
• Biomechanics and Mechanobiology
• Biomedical Imaging and Instrumentation
• Biotechnology
• Drug Delivery and Nanomedicine
• Mechanics of Biological Materials
• Nanobio Applications

Green Technologies

The 21st century has been called the "century of the environment." Neither governments nor individual citizens can any longer assume that social challenges such as pollution, dwindling natural resources and climate change can be set aside for future generations. Strategies for clean and sustainable communities need to be established now, community by community. A dawning era of creativity and innovation in "green technology" (also known as "clean technology") is bringing the promise of a healthier planet (as well as the prospect of growing businesses) that can sustain its health.  We have targeted green composites and new systems for CO2 capture and conversion as areas of future growth .

Creative engineering materials are continuously being developed, selected and used in all facets of industries, from consumer products to space exploration. Chemistry and physics are the backbone sciences in this field. Purposefully designed materials provide the means for modern products and tools to be built. Humanity has had a firm grasp of engineering materials and how to manipulate performance for centuries. However, until recently, we have not had the tools to fully understand the underlying mechanisms to such enhancements and provide optimized material solutions. Scientists and engineers develop and use basic principles to design new materials for different and ever-demanding applications. Materials design and behavior assessment is a function of mathematics, experimentation and a firm understanding of metallurgy and material science principles. Collaboratively, we are able to produce optimized materials that serve multiple functions within a given application and environment.

After this lesson, students should be able to:

• Describe basic structures of materials.
• Relate basic structures to four classes of materials.
• Identify modes of failure, mechanical behavior and relate to classes of materials.
• Explain materials development for engineering design requirements.
• Discuss various applications of materials and role in society.

(In advance, prepare to show students the 28-slide Introduction to Material Science and Engineering Presentation , a PowerPoint file, and gather materials to conduct a class demonstration. See materials and instructions, below. The presentation includes basic information regarding material classes, material applications, and material behavior and serves as a foundation for acquiring basic knowledge for the remainder of the lesson. Allow 20-30 minutes for the presentation. The class demo illustrates the different classes of materials and material behavior, and engages the students in a review of presentation content.)

What is material science? (Listen to student ideas.) If it weren't for material scientists and engineers, we would have never made it to the moon, nor would your laptop work!

What do I mean when I say "materials"? What are the different classes of materials? Why are they created? What are their characteristics? How do we test them? How are they used? That's what we're going to investigate today. Let's take a look.

Lesson Background and Concepts for Teachers

Material science has evolved during the last 40 years as different classes of materials became more and more competitive with one another. The four primary general classes of materials are metals, ceramics, polymers and composites. What makes these classes of materials unique is their composition, bonding and structure. Additionally, these distinct characteristics govern the applications for using each class of material. Following is a general summary of the four classes. Additional readings are suggested in the References section.

Material science is defined as the relationship of properties to its chemistry (composition) and structure. Understanding these relationships involves interdisciplinary knowledge of chemistry, physics and metallurgy. Provided engineers and scientists understand the type of atoms present and their arrangement, many properties may be understood and optimized for practical use. Chemical composition is fundamental in understanding any material type. Composition is the amount of an individual element that makes up a material. For example, steel is composed of iron and carbon and glass is composed of silicon, calcium, sodium, aluminum and oxygen. The structure can be defined as the arrangement of such elements (atoms), micro-features and macroscopic features.

Atomic structure is, as the name suggests, a particular arrangement of atoms and the electron structure. From chemistry, three primary forms of bonding exist: metallic, covalent and ionic. It is the atomic structure and interaction between elements that dictates which type of bonding prevails. Of course, additional bonding, such as hydrogen and London dispersion forces (van der Waals) exist and become important for polymers. For instance, metal alloys are strictly metallic bonding. Two metal elements with incomplete valence shells combine, filling the sub-valence shells, with remaining electrons present as a cloud. Interestingly, this electron arrangement is why metals are good electrical conductors. Ceramics are primarily bonded by strong covalent bonds and a few ionic bonds. The difference between the two is a sharing of valence electrons and transfer of valence electrons, respectively. The nature of these bonding types is why most ceramics are electrical insulators. Additionally, the nature of bonding is the source for many physical material properties and eventual mechanical properties. Bond strength is highly correlated to melting point, elastic stiffness and thermal expansion—meaning, the stronger the bonds the larger driving force is needed to separate such atoms.

For most solid materials, these arrangements are periodic and possess long-range order, with the exception of polymers and amorphous glasses. These periodic structures are called crystal structures and are present in seven primitive arrangements: cubic, hexagonal, triclinic, monoclinic, trigonal, tetragonal, and orthorhombic. These "lattices" are what make up the microstructure. Also, additional packing sequences that exist within each primitive arrangement create a total of 14 unit cells; most notable are body-centered cubic (BCC) and face-centered cubic (FCC). In addition to atomic bonding, these long-range atomic arrangements dictate inherent physical/mechanical properties and differentiate materials. For instance, BCC iron is much less ductile than FCC copper. The microstructure also includes larger features such as an array of crystals or grains, or a multitude of different solid phases. These features can be viewed using optical methods that do not require diffraction techniques or high magnification.

The macrostructure is the length scale that is comprised of a collection of microstructure features that show distinct characteristics. For example, collections of grains in a metal can be viewed at low magnification (x10) and appear to be flow lines or stripes. This length scale can provide very important details and can influence mechanical behavior of materials. A banded structure of steel can provide insights to fabrication methods and material strength. All of these length scales and distinct material features collectively make a material strong, fracture resistant, corrosion resistant, temperature resistant and ductile. However, no one material can have all of these wonderful attributes.

Pure Metals and Metal Alloys: Metal alloys are mixtures of two or more metallic elements. As mentioned earlier, metals are unique in that they are excellent electrical and thermal conductors. These physical properties are due to the nature of metallic bonding. Some metals also possess magnetic properties. Metals also possess a large capacity of mechanical deformation (aka ductility). Some metal bars can be shaped easily at room temperature. Most metals also have distinct strength levels: a yield stress (YS), and ultimate stress (UTS) and a fracture stress (FS), which collectively add to an entire mechanical response known as stress-strain behavior. To facilitate strength manipulation, metals have the capacity to be altered through mechanical, thermal or thermal mechanical treatments to achieve desired properties. Steel heat treatment for a hammer is different from that of a nail.

Ceramics: Ceramics are typically covalent-bonded solids that have very high melting points and stiffness. However, typically these materials are regarded as brittle. In contrast to metals and alloys, ceramics typically do not have distinct YSs and UTSs, but do have FSs. Ceramics are also useful in super-high temperature and corrosive environments. One advantage to the chemical compositions and bonding nature of ceramics is their inertness to many different corrosive media and oxidation environments. High temperature applications are suitable because of high strength retention at operating temperatures. Typical metals are too soft to sustain any mechanical loads at temperatures greater than 0.5 the melting point. Because of high stiffness, most ceramics are inherently hard and therefore abrasion- and wear-resistant. The hardest materials known are high-directional, covalent-bonded ceramics.

Polymers: Polymers are combinations of long-chained, covalent-bonded atoms that are mutually attracted by weaker bonding forces. Classic examples of polymers—car tires, Ziploc® bags, Kevlar®, glue and plastic water bottles—show the range of polymers that are manufactured and the variety of mechanical properties. Typically, polymers vary from very flexible, ductile materials to very hard and brittle materials. Polymers and their structures are dependent on the chemical composition of the base material and any fillers, extenders and plasticizers. Additionally, chemical composition also determines the degree of crystallinity in polymers. Typically, polymer chains are completely random and tangled. Depending on the chemistry, additives and stress state, these chains can obtain some periodic arrangement. Although, this arrangement is not counted as long-range order, polymers may possess short-range order.

Composite Materials: Composites are very common and not as scientific as one would think. Since ancient times, clay and straw have been mixed together to improve brick strength. Concrete, plywood, fiberglass and steel rebar are all common materials that are categorized as composites. In general, functional engineering materials for specific applications involve making composites from metal-ceramic, ceramic-ceramic, polymer-metal and polymer-polymer combinations. Depending on the application and properties required, different types of composite are selected. Composites allow for engineers and scientists to achieve unique property combinations that individual materials could not achieve. For instance, embedding ceramic particles in an aluminum or copper matrix improves both flexural strength and wear resistance, while maintaining a particular degree of toughening. However, aluminum alone is not very wear resistant and the ceramic has poor toughness. These unique properties are attractive and may not be provided by conventional materials.

All classes of material collectively account for all tangible objects on Earth. The field of material science enables the understanding and improvement of existing and new materials with the potential to catapult humanity to new frontiers.

The wealth of information in this lesson is adequate to intrigue students to consider pursuing paths of study in material science. The introductory presentation introduces the general classes of materials, terminology and applications. In general, students enjoy watching things break, especially if hammers are involved. How perfect, then, to introduce them to material science through the demonstration, as a way to reinforce the concepts relating all four material classes. Conducting the associated activity, Battle of the Beams , provides students with more insight into composite structures, while they apply concepts, and fabricate and test beams.

Students explore the basic characteristics of polymers through the introduction of two polymer categories: thermoplastics and thermosets. During teacher demos, students observe the unique behaviors of thermoplastics.

Students create beams using Laffy Taffy and water, and a choice of various reinforcements (pasta, rice, candies) and fabricating temperatures. Student groups compete for the highest strength beam and measure flexure strength with three-point bend tests and calculations.

Over several days, students learn about composites, including carbon-fiber-reinforced polymers, and their applications in modern life. This prepares students to be able to put data from an associated statistical analysis activity into context as they conduct meticulous statistical analyses to evalua...

Top 7 tips for your defense presentation

1. show why your study is important, remember, your audience is your committee members, researchers in other fields, and even the general public. you want to convince all of them why you deserve a ph.d. degree. you need to talk about why your study is important to the world. in the engineering field, you also need to talk about how your study is useful. try to discuss why current practice is problematic or not good enough, what needs to be solved, and what the potential benefits will be. , see how dr. posen and dr. malings explained the importance of their studies..

2. Emphasize YOUR contribution 

Having a ph.d. means that you have made some novel contributions to the grand field. this is about you and your research. you need to keep emphasizing your contributions throughout your presentation. after talking about what needs to be solved, try to focus on emphasizing the novelty of your work. what problems can be solved using your research outcomes what breakthroughs have you made to the field why are your methods and outcomes outstanding you need to incorporate answers to these questions in your presentation. , be clear what your contributions are in the introduction section; separate what was done by others and what was done by you. , 3. connect your projects into a whole piece of work, you might have been doing multiple projects that are not strongly connected. to figure out how to connect them into a whole piece, use visualizations such as flow charts to convince your audience. the two slides below are two examples. in the first slide, which was presented in the introduction section, the presenter used a flow diagram to show the connection between the three projects. in the second slide, the presenter used key figures and a unique color for each project to show the connection..

4. Tell a good story 

The committee members do not necessarily have the same background knowledge as you. plus, there could be researchers from other fields and even the general public in the room. you want to make sure all of your audience can understand as much as possible. focus on the big picture rather than technical details; make sure you use simple language to explain your methods and results. your committee has read your dissertation before your defense, but others have not. , dr. cook and dr. velibeyoglu did a good job explaining their research to everyone. the introduction sessions in their presentations are well designed for this purpose. .

• Laren M. Cook Defense Slides with Notes
• Irem Velibeyoglu Defense with Notes

5. Transition, transition, transition

Use transition slides to connect projects , it's a long presentation with different research projects. you want to use some sort of transition to remind your audience what you have been talking about and what is next. you may use a slide that is designed for this purpose throughout your presentation. , below are two examples. these slides were presented after the introduction section. the presenters used the same slides and highlighted the items for project one to indicate that they were moving on to the first project. throughout the presentation, they used these slides and highlighted different sections to indicate how these projects fit into the whole dissertation. .

You can also use some other indications on your slides, but remember not to make your slides too busy.  Below are two examples. In the first example, the presenter used chapter numbers to indicate what he was talking about. In the second example, the presenter used a progress bar with keywords for each chapter as the indicator. 

Use transition sentences to connect slides 

Remember transition sentences are also important; use them to summarize what you have said and tell your audience what they will expect next. if you keep forgetting the transition sentence, write a note on your presentation. you can either write down a full sentence of what you want to say or some keywords., 6. be brief, put details in backup slides , you won't have time to explain all of the details. if your defense presentation is scheduled for 45 minutes, you can only spend around 10 minutes for each project - that's shorter than a normal research conference presentation focus on the big picture and leave details behind. you can put the details in your backup slides, so you might find them useful when your committee (and other members of the audience) ask questions regarding these details., 7. show your presentation to your advisor and colleagues, make sure to ask your advisor(s) for their comments. they might have a different view on what should be emphasized and what should be elaborated. , you also want to practice at least once in front of your colleagues. they can be your lab mates, people who work in your research group, and/or your friends. they do not have to be experts in your field. ask them to give you some feedback - their comments can be extremely helpful to improve your presentation. , below are some other tips and resources to design your defense presentation. .

How to make a scientific presentation

Scientific presentation outlines

Questions to ask yourself before you write your talk, 1. how much time do you have, 2. who will you speak to, 3. what do you want the audience to learn from your talk, step 1: outline your presentation, step 2: plan your presentation slides, step 3: make the presentation slides, slide design, text elements, animations and transitions, step 4: practice your presentation, final thoughts, frequently asked questions about preparing scientific presentations, related articles.

A good scientific presentation achieves three things: you communicate the science clearly, your research leaves a lasting impression on your audience, and you enhance your reputation as a scientist.

But, what is the best way to prepare for a scientific presentation? How do you start writing a talk? What details do you include, and what do you leave out?

It’s tempting to launch into making lots of slides. But, starting with the slides can mean you neglect the narrative of your presentation, resulting in an overly detailed, boring talk.

The key to making an engaging scientific presentation is to prepare the narrative of your talk before beginning to construct your presentation slides. Planning your talk will ensure that you tell a clear, compelling scientific story that will engage the audience.

In this guide, you’ll find everything you need to know to make a good oral scientific presentation, including:

• The different types of oral scientific presentations and how they are delivered;
• How to outline a scientific presentation;
• How to make slides for a scientific presentation.

Our advice results from delving into the literature on writing scientific talks and from our own experiences as scientists in giving and listening to presentations. We provide tips and best practices for giving scientific talks in a separate post.

There are two main types of scientific talks:

• Your talk focuses on a single study . Typically, you tell the story of a single scientific paper. This format is common for short talks at contributed sessions in conferences.
• Your talk describes multiple studies. You tell the story of multiple scientific papers. It is crucial to have a theme that unites the studies, for example, an overarching question or problem statement, with each study representing specific but different variations of the same theme. Typically, PhD defenses, invited seminars, lectures, or talks for a prospective employer (i.e., “job talks”) fall into this category.

➡️ Learn how to prepare an excellent thesis defense

The length of time you are allotted for your talk will determine whether you will discuss a single study or multiple studies, and which details to include in your story.

The background and interests of your audience will determine the narrative direction of your talk, and what devices you will use to get their attention. Will you be speaking to people specializing in your field, or will the audience also contain people from disciplines other than your own? To reach non-specialists, you will need to discuss the broader implications of your study outside your field.

The needs of the audience will also determine what technical details you will include, and the language you will use. For example, an undergraduate audience will have different needs than an audience of seasoned academics. Students will require a more comprehensive overview of background information and explanations of jargon but will need less technical methodological details.

Your goal is to speak to the majority. But, make your talk accessible to the least knowledgeable person in the room.

This is called the thesis statement, or simply the “take-home message”. Having listened to your talk, what message do you want the audience to take away from your presentation? Describe the main idea in one or two sentences. You want this theme to be present throughout your presentation. Again, the thesis statement will depend on the audience and the type of talk you are giving.

Your thesis statement will drive the narrative for your talk. By deciding the take-home message you want to convince the audience of as a result of listening to your talk, you decide how the story of your talk will flow and how you will navigate its twists and turns. The thesis statement tells you the results you need to show, which subsequently tells you the methods or studies you need to describe, which decides the angle you take in your introduction.

➡️ Learn how to write a thesis statement

The goal of your talk is that the audience leaves afterward with a clear understanding of the key take-away message of your research. To achieve that goal, you need to tell a coherent, logical story that conveys your thesis statement throughout the presentation. You can tell your story through careful preparation of your talk.

Preparation of a scientific presentation involves three separate stages: outlining the scientific narrative, preparing slides, and practicing your delivery. Making the slides of your talk without first planning what you are going to say is inefficient.

Here, we provide a 4 step guide to writing your scientific presentation:

• Outline your presentation
• Plan your presentation slides
• Make the presentation slides
• Practice your presentation

Writing an outline helps you consider the key pieces of your talk and how they fit together from the beginning, preventing you from forgetting any important details. It also means you avoid changing the order of your slides multiple times, saving you time.

Plan your talk as discrete sections. In the table below, we describe the sections for a single study talk vs. a talk discussing multiple studies:

The following tips apply when writing the outline of a single study talk. You can easily adapt this framework if you are writing a talk discussing multiple studies.

Introduction: Writing the introduction can be the hardest part of writing a talk. And when giving it, it’s the point where you might be at your most nervous. But preparing a good, concise introduction will settle your nerves.

The introduction tells the audience the story of why you studied your topic. A good introduction succinctly achieves four things, in the following order.

• It gives a broad perspective on the problem or topic for people in the audience who may be outside your discipline (i.e., it explains the big-picture problem motivating your study).
• It describes why you did the study, and why the audience should care.
• It gives a brief indication of how your study addressed the problem and provides the necessary background information that the audience needs to understand your work.
• It indicates what the audience will learn from the talk, and prepares them for what will come next.

A good introduction not only gives the big picture and motivations behind your study but also concisely sets the stage for what the audience will learn from the talk (e.g., the questions your work answers, and/or the hypotheses that your work tests). The end of the introduction will lead to a natural transition to the methods.

Give a broad perspective on the problem. The easiest way to start with the big picture is to think of a hook for the first slide of your presentation. A hook is an opening that gets the audience’s attention and gets them interested in your story. In science, this might take the form of a why, or a how question, or it could be a statement about a major problem or open question in your field. Other examples of hooks include quotes, short anecdotes, or interesting statistics.

Why should the audience care? Next, decide on the angle you are going to take on your hook that links to the thesis of your talk. In other words, you need to set the context, i.e., explain why the audience should care. For example, you may introduce an observation from nature, a pattern in experimental data, or a theory that you want to test. The audience must understand your motivations for the study.

Supplementary details. Once you have established the hook and angle, you need to include supplementary details to support them. For example, you might state your hypothesis. Then go into previous work and the current state of knowledge. Include citations of these studies. If you need to introduce some technical methodological details, theory, or jargon, do it here.

Conclude your introduction. The motivation for the work and background information should set the stage for the conclusion of the introduction, where you describe the goals of your study, and any hypotheses or predictions. Let the audience know what they are going to learn.

Methods: The audience will use your description of the methods to assess the approach you took in your study and to decide whether your findings are credible. Tell the story of your methods in chronological order. Use visuals to describe your methods as much as possible. If you have equations, make sure to take the time to explain them. Decide what methods to include and how you will show them. You need enough detail so that your audience will understand what you did and therefore can evaluate your approach, but avoid including superfluous details that do not support your main idea. You want to avoid the common mistake of including too much data, as the audience can read the paper(s) later.

Results: This is the evidence you present for your thesis. The audience will use the results to evaluate the support for your main idea. Choose the most important and interesting results—those that support your thesis. You don’t need to present all the results from your study (indeed, you most likely won’t have time to present them all). Break down complex results into digestible pieces, e.g., comparisons over multiple slides (more tips in the next section).

Summary: Summarize your main findings. Displaying your main findings through visuals can be effective. Emphasize the new contributions to scientific knowledge that your work makes.

Conclusion: Complete the circle by relating your conclusions to the big picture topic in your introduction—and your hook, if possible. It’s important to describe any alternative explanations for your findings. You might also speculate on future directions arising from your research. The slides that comprise your conclusion do not need to state “conclusion”. Rather, the concluding slide title should be a declarative sentence linking back to the big picture problem and your main idea.

It’s important to end well by planning a strong closure to your talk, after which you will thank the audience. Your closing statement should relate to your thesis, perhaps by stating it differently or memorably. Avoid ending awkwardly by memorizing your closing sentence.

By now, you have an outline of the story of your talk, which you can use to plan your slides. Your slides should complement and enhance what you will say. Use the following steps to prepare your slides.

• Write the slide titles to match your talk outline. These should be clear and informative declarative sentences that succinctly give the main idea of the slide (e.g., don’t use “Methods” as a slide title). Have one major idea per slide. In a YouTube talk on designing effective slides , researcher Michael Alley shows examples of instructive slide titles.
• Decide how you will convey the main idea of the slide (e.g., what figures, photographs, equations, statistics, references, or other elements you will need). The body of the slide should support the slide’s main idea.
• Under each slide title, outline what you want to say, in bullet points.

In sum, for each slide, prepare a title that summarizes its major idea, a list of visual elements, and a summary of the points you will make. Ensure each slide connects to your thesis. If it doesn’t, then you don’t need the slide.

Slides for scientific presentations have three major components: text (including labels and legends), graphics, and equations. Here, we give tips on how to present each of these components.

• Have an informative title slide. Include the names of all coauthors and their affiliations. Include an attractive image relating to your study.
• Make the foreground content of your slides “pop” by using an appropriate background. Slides that have white backgrounds with black text work well for small rooms, whereas slides with black backgrounds and white text are suitable for large rooms.
• The layout of your slides should be simple. Pay attention to how and where you lay the visual and text elements on each slide. It’s tempting to cram information, but you need lots of empty space. Retain space at the sides and bottom of your slides.
• Use sans serif fonts with a font size of at least 20 for text, and up to 40 for slide titles. Citations can be in 14 font and should be included at the bottom of the slide.
• Use bold or italics to emphasize words, not underlines or caps. Keep these effects to a minimum.
• Use concise text . You don’t need full sentences. Convey the essence of your message in as few words as possible. Write down what you’d like to say, and then shorten it for the slide. Remove unnecessary filler words.
• Text blocks should be limited to two lines. This will prevent you from crowding too much information on the slide.
• Include names of technical terms in your talk slides, especially if they are not familiar to everyone in the audience.
• Proofread your slides. Typos and grammatical errors are distracting for your audience.
• Include citations for the hypotheses or observations of other scientists.
• Good figures and graphics are essential to sustain audience interest. Use graphics and photographs to show the experiment or study system in action and to explain abstract concepts.
• Don’t use figures straight from your paper as they may be too detailed for your talk, and details like axes may be too small. Make new versions if necessary. Make them large enough to be visible from the back of the room.
• Use graphs to show your results, not tables. Tables are difficult for your audience to digest! If you must present a table, keep it simple.
• Label the axes of graphs and indicate the units. Label important components of graphics and photographs and include captions. Include sources for graphics that are not your own.
• Explain all the elements of a graph. This includes the axes, what the colors and markers mean, and patterns in the data.
• Use colors in figures and text in a meaningful, not random, way. For example, contrasting colors can be effective for pointing out comparisons and/or differences. Don’t use neon colors or pastels.
• Use thick lines in figures, and use color to create contrasts in the figures you present. Don’t use red/green or red/blue combinations, as color-blind audience members can’t distinguish between them.
• Arrows or circles can be effective for drawing attention to key details in graphs and equations. Add some text annotations along with them.
• Write your summary and conclusion slides using graphics, rather than showing a slide with a list of bullet points. Showing some of your results again can be helpful to remind the audience of your message.
• If your talk has equations, take time to explain them. Include text boxes to explain variables and mathematical terms, and put them under each term in the equation.
• Combine equations with a graphic that shows the scientific principle, or include a diagram of the mathematical model.
• Use animations judiciously. They are helpful to reveal complex ideas gradually, for example, if you need to make a comparison or contrast or to build a complicated argument or figure. For lists, reveal one bullet point at a time. New ideas appearing sequentially will help your audience follow your logic.
• Slide transitions should be simple. Silly ones distract from your message.
• Decide how you will make the transition as you move from one section of your talk to the next. For example, if you spend time talking through details, provide a summary afterward, especially in a long talk. Another common tactic is to have a “home slide” that you return to multiple times during the talk that reinforces your main idea or message. In her YouTube talk on designing effective scientific presentations , Stanford biologist Susan McConnell suggests using the approach of home slides to build a cohesive narrative.

To deliver a polished presentation, it is essential to practice it. Here are some tips.

• For your first run-through, practice alone. Pay attention to your narrative. Does your story flow naturally? Do you know how you will start and end? Are there any awkward transitions? Do animations help you tell your story? Do your slides help to convey what you are saying or are they missing components?
• Next, practice in front of your advisor, and/or your peers (e.g., your lab group). Ask someone to time your talk. Take note of their feedback and the questions that they ask you (you might be asked similar questions during your real talk).
• Edit your talk, taking into account the feedback you’ve received. Eliminate superfluous slides that don’t contribute to your takeaway message.
• Practice as many times as needed to memorize the order of your slides and the key transition points of your talk. However, don’t try to learn your talk word for word. Instead, memorize opening and closing statements, and sentences at key junctures in the presentation. Your presentation should resemble a serious but spontaneous conversation with the audience.
• Practicing multiple times also helps you hone the delivery of your talk. While rehearsing, pay attention to your vocal intonations and speed. Make sure to take pauses while you speak, and make eye contact with your imaginary audience.
• Make sure your talk finishes within the allotted time, and remember to leave time for questions. Conferences are particularly strict on run time.
• Anticipate questions and challenges from the audience, and clarify ambiguities within your slides and/or speech in response.
• If you anticipate that you could be asked questions about details but you don’t have time to include them, or they detract from the main message of your talk, you can prepare slides that address these questions and place them after the final slide of your talk.

➡️ More tips for giving scientific presentations

An organized presentation with a clear narrative will help you communicate your ideas effectively, which is essential for engaging your audience and conveying the importance of your work. Taking time to plan and outline your scientific presentation before writing the slides will help you manage your nerves and feel more confident during the presentation, which will improve your overall performance.

A good scientific presentation has an engaging scientific narrative with a memorable take-home message. It has clear, informative slides that enhance what the speaker says. You need to practice your talk many times to ensure you deliver a polished presentation.

First, consider who will attend your presentation, and what you want the audience to learn about your research. Tailor your content to their level of knowledge and interests. Second, create an outline for your presentation, including the key points you want to make and the evidence you will use to support those points. Finally, practice your presentation several times to ensure that it flows smoothly and that you are comfortable with the material.

Prepare an opening that immediately gets the audience’s attention. A common device is a why or a how question, or a statement of a major open problem in your field, but you could also start with a quote, interesting statistic, or case study from your field.

Scientific presentations typically either focus on a single study (e.g., a 15-minute conference presentation) or tell the story of multiple studies (e.g., a PhD defense or 50-minute conference keynote talk). For a single study talk, the structure follows the scientific paper format: Introduction, Methods, Results, Summary, and Conclusion, whereas the format of a talk discussing multiple studies is more complex, but a theme unifies the studies.

Ensure you have one major idea per slide, and convey that idea clearly (through images, equations, statistics, citations, video, etc.). The slide should include a title that summarizes the major point of the slide, should not contain too much text or too many graphics, and color should be used meaningfully.

Processing of Micro- and Nanoscale Materials

Electronic properties of engineering materials, conductors and resistors.

• The Drude model of electrical conduction was developed in the 1900s by Paul Drude to explain the transport properties of electrons in materials (especially metals). The Drude model is the application of kinetic theory to electrons in a solid. It assumes that the material contains immobile positive ions and an "electron gas" of classical, non-interacting electrons of density n, each of whose motion is damped by a frictional force due to collisions of the electrons with the ions, characterized by a relaxation time τ.
• Resistance Modeled as Viscosity
• The Hall effect refers to the potential difference (Hall voltage) on the opposite sides of an electrical conductor through which an electric current is flowing, created by a magnetic field applied perpendicular to the current.

• An alternating current (AC) is an electrical current whose magnitude and direction vary cyclically, as opposed to direct current, whose direction remains constant. The usual waveform of an AC power circuit is a sine wave, as this results in the most efficient transmission of energy. However in certain applications different waveforms are used, such as triangular or square waves. Used generically, AC refers to the form in which electricity is delivered to businesses and residences. However, audio and radio signals carried on electrical wire are also examples of alternating current. In these applications, an important goal is often the recovery of information encoded (or modulated) onto the AC signal.
• In physics, thermal conductivity, k, is the property of a material that indicates its ability to conduct heat. It is used primarily in Fourier's Law for heat conduction.
• Heat capacity (symbol: Cp) — as distinct from specific heat capacity — is the measure of the heat energy required to increase the temperature of an object by a certain temperature interval. Heat capacity is an extensive property because its value is proportional to the amount of material in the object; for example, a bathtub of water has a greater heat capacity than a cup of water.

Optical Properties of Conductors

• In vector calculus, the gradient of a scalar field is a vector field which points in the direction of the greatest rate of increase of the scalar field, and whose magnitude is the greatest rate of change.
• In vector calculus, the divergence is an operator that measures the magnitude of a vector field's source or sink at a given point; the divergence of a vector field is a (signed) scalar. For a vector field that denotes the velocity of air expanding as it is heated, the divergence of the velocity field would have a positive value because the air expands. If the air cools and contracts, the divergence is negative. The divergence could be thought of as a measure of the change in density.
• In vector calculus, curl is a vector operator that shows a vector field's "rate of rotation", that is the direction of the axis of rotation and the magnitude of the rotation. It can also be described as the circulation density. In many European countries the operator is called rot (short for rotor) instead of curl.
• Permittivity is a physical quantity that describes how an electric field affects and is affected by a dielectric medium, and is determined by the ability of a material to polarize in response to the field, and thereby reduce the total electric field inside the material. Thus, permittivity relates to a material's ability to transmit (or "permit") an electric field. It is directly related to electric susceptibility. For example, in a capacitor, an increased permittivity allows the same charge to be stored with a smaller electric field (and thus a smaller voltage), leading to an increased capacitance.

• Stokes' theorem (or Stokes's theorem) in differential geometry is a statement about the integration of differential forms which generalizes several theorems from vector calculus. It is named after Sir George Gabriel Stokes (1819–1903), although the first known statement of the theorem is by William Thomson (Lord Kelvin) and appears in a letter of his to Stokes.
• The classical Kelvin-Stokes theorem:

• The wave equation is an important second-order linear partial differential equation that describes the propagation of a variety of waves, such as sound waves, light waves and water waves. It arises in fields such as acoustics, electromagnetics, and fluid dynamics. Historically, the problem of a vibrating string such as that of a musical instrument was studied by Jean le Rond d'Alembert, Leonhard Euler, Daniel Bernoulli, and Joseph-Louis Lagrange.

• When an electromagnetic wave interacts with a conductive material, mobile charges within the material are made to oscillate back and forth with the same frequency as the impinging fields. The movement of these charges, usually electrons, constitutes an alternating electric current, the magnitude of which is greatest at the conductor's surface. The decline in current density versus depth is known as the skin effect and the skin depth is a measure of the distance over which the current falls to 1/e of its original value. A gradual change in phase accompanies the change in magnitude, so that, at a given time and at appropriate depths, the current can be flowing in the opposite direction to that at the surface.
• The ionosphere is the uppermost part of the atmosphere, distinguished because it is ionized by solar radiation. It plays an important part in atmospheric electricity and forms the inner edge of the magnetosphere. It has practical importance because, among other functions, it influences radio propagation to distant places on the Earth. It is located in the Thermosphere.
• In solid state physics, a particle's effective mass is the mass it seems to carry in the semiclassical model of transport in a crystal. It can be shown that, under most conditions, electrons and holes in a crystal respond to electric and magnetic fields almost as if they were free particles in a vacuum, but with a different mass. This mass is usually stated in units of the ordinary mass of an electron me (9.11×10-31 kg).

Insulators and Capacitors

• In classical electromagnetism, the polarization density (or electric polarization, or simply polarization) is the vector field that expresses the density of permanent or induced electric dipole moments in a dielectric material. The polarization vector P is defined as the dipole moment per unit volume. The SI unit of measure is coulombs per square metre.
• A capacitor is an electrical/electronic device that can store energy in the electric field between a pair of conductors (called "plates"). The process of storing energy in the capacitor is known as "charging", and involves electric charges of equal magnitude, but opposite polarity, building up on each plate. The capacitor's capacitance (C) is a measure of the amount of charge (Q) stored on each plate for a given potential difference or voltage (V) which appears between the plates:

• The relative static permittivity (or static relative permittivity) of a material under given conditions is a measure of the extent to which it concentrates electrostatic lines of flux. It is the ratio of the amount of stored electrical energy when a potential is applied, relative to the permittivity of a vacuum. The relative static permittivity is the same as the relative permittivity evaluated for a frequency of zero.

• In physics, the electric displacement field or electric induction is a vector field \mathbf{D} that appears in Maxwell's equations. It accounts for the effects of unbound charges within materials. "D" stands for "displacement," as in the related concept of displacement current in dielectrics.
• The theoretical dielectric strength of a material is an intrinsic property of the bulk material and is dependent on the configuration of the material or the electrodes with which the field is applied. At breakdown, the electric field frees bound electrons. If the applied electric field is sufficiently high, free electrons may become accelerated to velocities that can liberate additional electrons during collisions with neutral atoms or molecules in a process called avalanche breakdown. Breakdown occurs quite abruptly (typically in nanoseconds), resulting in the formation of an electrically conductive path and a disruptive discharge through the material. For solid materials, a breakdown event severely degrades, or even destroys, its insulating capability.

Optical Properties of Insulators

• Wave equations in a dielectric

• Relationship between dielectric constant and index of refraction

• Snell's law

• Total internal reflection is an optical phenomenon that occurs when a ray of light strikes a medium boundary at an angle larger than the critical angle with respect to the normal to the surface. If the refractive index is lower on the other side of the boundary no light can pass through, so effectively all of the light is reflected. The critical angle is the angle of incidence above which the total internal reflection occurs.
• In optics, dispersion is the phenomenon that the phase velocity of a wave depends on its frequency. In a prism, dispersion causes the spatial separation of a white light into spectral components of different wavelengths. Dispersion is most often described in light waves, but it may happen to any kind of wave that interacts with a medium or can be confined to a waveguide, such as sound waves. Dispersion is sometimes called chromatic dispersion to emphasize its wavelength-dependent nature.
• Attenuation is the reduction in amplitude and intensity of a signal. Signals may be attenuated exponentially by transmission through a medium, in which case attenuation is usually reported in dB with respect to distance traveled through the medium. Attenuation can also be understood to be the opposite of amplification. Attenuation is an important property in telecommunications and ultrasound applications because of its importance in determining signal strength as a function of distance. Attenuation is usually measured in units of decibels per unit length of medium (dB/cm, dB/km, etc) and is represented by the attenuation coefficient of the medium in question. Attenuation decreases the intensity of electromagnetic radiation due to absorption or scattering of photons. Attenuation does not include the decrease in intensity due to inverse-square law geometric spreading. Therefore, calculation of the total change in intensity involves both the inverse-square law and an estimation of attenuation over the path.

• Diffraction refers to various phenomena associated with the bending of waves when they interact with obstacles in their path. It occurs with any type of wave, including sound waves, water waves, and electromagnetic waves such as visible light, x-rays and radio waves. As physical objects have wave-like properties, diffraction also occurs with matter and can be studied according to the principles of quantum mechanics. While diffraction always occurs when propagating waves encounter obstacles in their paths, its effects are generally most pronounced for waves where the wavelength is on the order of the size of the diffracting objects. The complex patterns resulting from the intensity of a diffracted wave are a result of interference between different parts of a wave that traveled to the observer by different paths.
