Make Your Own Shampoo and Test How It Performs!

Science Fair Project Idea

Scientific Method

Do you love it when your hair is nice and fresh? The key to keeping your hair nice and clean is to use a good shampoo. But with so many different products in the store, how do you know which one works best for you? In this science project, you will put a variety of shampoos to the test, including your own homemade organic shampoo recipes. Do you think these will perform better than a store-bought product?

Measuring the Speed of 'Light' with a Microwave Oven

Science Fair Project Idea

Scientific Method

Did you know that you can measure the speed of light using a microwave oven, some egg white, and a ruler? Find out how with this cool kitchen science project thanks to Mr. Nick Hood, a science teacher in Fife, Scotland. Read more

How does surface area affect the speed of a chemical reaction? Let your students find out in this sizzling lesson plan! In this project, they will explore this correlation by crushing Alka-Seltzer® tablets into different sized particles and measuring how long it takes for them to dissolve in water. Read more

NGSS Performance Expectations:

HS-PS1-5. Apply scientific principles and evidence to provide an explanation about the effects of changing the temperature or concentration of the reacting particles on the rate at which a reaction occurs.

Teaching Machines to Understand Sign Language

Science Fair Project Idea

Engineering Design Process

Can AI understand human language? In the future, AI could aid in emergency interpretive service in the hospital when translators aren't available. But can current AI algorithms understand non-verbal languages like sign language? In this science project, you will test whether AI can learn sign language gestures or phrases to see if it can be used for interpretation. Read more

Using a Laser to Measure the Speed of Light in Gelatin

Science Fair Project Idea

Scientific Method

Think it takes expensive, sophisticated equipment to measure the speed of light? Think again! Outfit yourself with a simple handheld laser pointer, a protractor, and gelatin, and you're ready to get started. Read more

Basketball: The Geometry of Banking a Basket

Science Fair Project Idea

Scientific Method

If you've ever played or watched basketball, you might already know that your chances of successfully banking a shot on the backboard are higher in certain positions on the basketball court, even when keeping the distance from the hoop the same. Ever wondered what would account for this? Do you think you could actually explain this using geometry? This science project will put your knowledge of geometry and algebra to good use. You will calculate and quantify how much more difficult it is to… Read more

Have you ever ridden in a car driving across a suspension bridge? Suspension bridges, with their tall towers, long spans and gracefully curving cables, are beautiful examples of the work of civil engineers. How do the cables and towers carry the load that is on the bridge, which includes you and the car you are in when you cross the bridge? Can a suspension bridge carry a greater load than a simple beam bridge? You can try to answer these questions in this science activity! Read more

Build an Arduino Walking Robot

Science Fair Project Idea

Engineering Design Process

Plenty of animals, like dogs and horses, can walk and run on four legs, but what about robots? Sometimes legs are better than wheels—try out this project to design and build your own quadruped walking robot! Read more

Build Your Own Super-sensitive Electric Field Detector

Science Fair Project Idea

Scientific Method

Wouldn't it be nice to avoid those nasty electric shocks you get after you have walked around on carpet and then touch a doorknob? These shocks are caused by static electricity. In this project, you will build a super-sensitive charge detector to investigate the electric fields created by static electricity. The detector can sense invisible electric fields before you touch something and get zapped, so try this project to avoid the shock of shocks! Read more

Can You Train People to Breathe Better?

Science Fair Project Idea

Scientific Method

The practice of "belly breathing" has been linked to improve mood, relaxation, and even have physical benefits like lowering your heart rate when compared to chest breathing. However, most of the time, we do not think about breathing—our bodies do it automatically. How do you know if you are belly breathing instead of chest breathing? How can you practice and get better at it? In this project you will build your own device to provide visual feedback about how a person breathes, then see… Read more
