Set Your Table for a Sweet and Sticky Earthquake Shake

Science Fair Project Idea

Scientific Method

Have you ever been in an earthquake? What did it feel like? Did you jiggle back and forth? Up and down? Was there a jolt? Or a rolling motion? Come build a house Hansel and Gretel would love to eat, a special table to shake it on, and see how different soil types can amplify shaking. Read more

Cricket Wicket Knockdown Challenge

Science Fair Project Idea

Scientific Method

In this cricket-inspired engineering challenge, you will build a machine to launch a ball and knock down a target (called a wicket). How many times can you knock down the wicket in three minutes? Teachers, lesson plan versions of this challenge are also available. Read more

Build a Solar-Powered Car

Science Fair Project Idea

Scientific Method

Do you want to build a solar-powered car? How about enter it in a competition and race it against other people's designs? If so, this is the project for you! These instructions will show you how to get started building a solar-powered car that you can enter in a science or engineering fair. No experience needed. If you want, you can even compete in the Junior Solar Sprint, a regional competition for solar-powered cars. Get more information about your regional competition. Are you a… Read more

Happy or Sad? Use Artificial Intelligence to Classify Faces

Science Fair Project Idea

Engineering Design Process

Do you think artificial intelligence (AI) is too complex to use? Think again! In this project, you will use AI to teach a web-based tool to classify happy and sad faces, or other objects, poses, or sounds. This experiment requires no coding skills; instead, you will need curiosity, creativity, and a critical eye. Why not give it a try yourself? Read more

Build Obstacle-Detecting Glasses for Visually Impaired People

Science Fair Project Idea

Engineering Design Process

Many visually impaired people use canes to detect obstacles at ground level. What about detecting an obstacle at face level, like a tree branch? What if you need to keep both your hands free and cannot hold a cane? Solve both problems at once with these obstacle-detecting glasses! The glasses use an ultrasonic sensor to measure distance and a buzzer to alert the user of nearby objects. You can customize the design to add or swap out features, like using a vibration motor instead of a buzzer.… Read more

Can Humans Recognize AI-Generated Text?

Science Fair Project Idea

Scientific Method

AI (artificial intelligence)-generated text is a hot topic for many reasons. Computers can now generate convincing paragraphs or even pages of text that look like they were written by a human. How do you know if a news article you are reading was written by a human or an AI? How does a teacher know if a student's essay was written by an AI? How do you know this text was not written by an AI? In this science project, you will conduct an experiment to see if volunteers can correctly identify… Read more

Cold Pack Chemistry: Where Does the Heat Go?

Science Fair Project Idea

Scientific Method

Instant cold packs are popular with coaches and parents for treating minor bumps and bruises. The instant cold packs are not pre-cooled—you just squeeze the cold pack and its starts to get cold. So how does it work? In this chemistry science fair project, you will investigate the chemical reaction that occurs in instant cold packs. Read more

How Much Current Does It Take To Blow Up An LED?

Science Fair Project Idea

Scientific Method

Have you ever accidentally burned out an LED while building a circuit? What about doing it on purpose—for science, of course! In this science project, you will intentionally send too much current through LEDs to see if they will burn out or even explode! How much current does it take to destroy an LED? How does this compare to the LED's rated current value? Try this project and find out! Check out this page for more LED science projects. Read more

Build a Gauss Rifle!

Science Fair Project Idea

Scientific Method

What can you do with magnets and ball bearings that makes a lot of noise? Why, build a magnetic linear accelerator, called a Gauss rifle, of course! Now, this magnetic accelerator is not a weapon, but a way for you to learn a lot more about physics concepts, like momentum. In this physics science project, you will investigate how far a ball bearing launched by a Gauss rifle will fly, depending on how many magnetic acceleration stages are in the setup and the ball bearing's initial velocity.… Read more

Make an Origami Robotic Gripper

Science Fair Project Idea

Engineering Design Process

Do you like making paper airplanes? What about origami animals? Have you ever thought about making a paper robot? In this engineering project, you will make a three-dimensional robotic gripper that starts out as a single flat sheet of paper! Try it out—see what objects you can pick up with the gripper, then see if you can improve the design. Read more
