Science Fair Project Idea

Engineering Design Process

MrBeast, the world's most famous YouTuber, has a series of challenge videos where he asks a contestant to protect some valuable prize - like a pile of money or an expensive car - from a series of attacks like explosions, giant fireballs launched from catapults, or even getting hit by a train! Contestants often have only 24 hours to build something to protect their prize, which presents a very interesting engineering challenge. Given limited time and access to materials, how can you best protect… Read more

The See-Saw as a Simple Machine

Science Fair Project Idea

Scientific Method

Have you ever tried to pull out a nail out of wood with your bare hands? Or have you tried to shove a staple through a stack of papers without a stapler? A hammer's claw, a stapler, a pair of pliers and a shovel are each examples of everyday tools that use levers to make our work easier. Read more

Extreme Sounds: Lessons in a Noisy World

Science Fair Project Idea

Scientific Method

Can you hear me now . . . ? Just how loud does a sound have to be for us to hear it? And how loud is too loud for our ears? Learn to measure levels of sound in this project, and discover the amazing auditory range your ears can detect in the noisy world around you. If you have a smartphone handy, you can even do this project without purchasing any additional materials, by using your phone's sound sensor and a sensor app. Read more

Centripetal Force

Science Fair Project Idea

Scientific Method

What keeps you in your seat of a giant loop-de-loop roller coaster? Surprisingly, it is not the seatbelt but the seat! It works because of something called centripetal force and it does much more than make a great roller coaster. It keeps a satellite in orbit and you in your bicycle seat during a turn. How does it work? Read more

Can You Hear Sounds in Outer Space?

Science Fair Project Idea

Scientific Method

Have you ever wondered what sounds you can hear in space? The answer is simple: none! In outer space there is utter silence. There are no sounds of traffic jams or thunderstorms or crashing waves. No buzzing bees or babies crying. Just silence. In this experiment, you will discover why empty space is void of sound and prove it with the help of the microphone in your phone and a sensor app. Read more

Making A Candy Waterfall: Can Solids Flow Like Liquids?

Science Fair Project Idea

Scientific Method

What do sand, Skittles, and cereal have in common? They are all granular materials, which means they are made up of solid particles, but they can actually flow like liquid! Imagine pouring the sand out of a bucket or pouring the cereal out of a box— a lot like pouring water, right? In this physics science project, you will investigate how the size of granular materials affect how they flow. Read more

Use a Catapult to Storm Castle Walls

Science Fair Project Idea

Scientific Method

You may have seen movies or read books where armies in medieval times catapulted large rocks or other objects at castles (or each other!). These armies used different types of catapults to accomplish different goals — for example, launching things over or into castle walls to knock them down. In this experiment, you will use a ping-pong ball catapult to lay siege to a "castle" and find the right settings to hit your targets. Read more

How to Balance Anything

Science Fair Project Idea

Scientific Method

Ever wonder why it is harder to keep your balance with a heavy backpack on? Or why it is difficult to make a toddler's sippy cup tip over? Maybe you are the kind of person who wonders about circus balancing acts and would like to learn how to ride a bike on a rope. Or perhaps you want to know how to make your toy car less prone to toppling over when racing through a sharp curve. In this science project you can learn about balance using marshmallows, skewers, and toothpicks. Sticky, yummy… Read more

Spinning Colors: How Do Primary Colors Combine to Make New Colors?

Science Fair Project Idea

Scientific Method

Did you know that sunlight can actually be separated into the colors of the rainbow? And the light of different colors can be added together to make white light or new colors. This is an area of study where art and science overlap. In this science fair project, you will explore this area by drawing or painting "pie slices" onto a white circle and then combining them to make a new color by spinning the wheel using an electric drill.

Simulate Microchip Clean Room Contamination with Crayon Leaf Rubbings

Science Fair Project Idea

Scientific Method

Have you ever made a leaf rubbing or imprint using paper and crayons? What do you think would happen if you got dirt or sand on the leaf? Would it mess up the result? In this project you will find out and learn about how this is related to the process of making the microchips that run our phones, computers, and other electronic devices. Check out this page for more science projects related to this process. Read more
