Science Fair Project Idea

Scientific Method

The funny thing about friction is that you couldn't get anywhere without it, yet it still acts to slow you down as you're getting there. Here is an easy project to measure the effects of friction. Read more

MrBeast "Protect the Prize" Challenge

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

How Protective is Your Helmet?

Science Fair Project Idea

Scientific Method

Every time you hop on your bike or gear up for football or baseball practice, your helmet is your first line of defense. Whether you’re coasting downhill or tackling on the gridiron, impacts happen — and they can cause more than just bumps and bruises. Scientists tell us that forceful hits to the head can lead to concussions or even more serious brain injury over time. Correct helmet design, proper fit, and good cushioning all help reduce those risks. For example, bicycling is one… Read more

Rubber Band Elasticity and Temperature

Science Fair Project Idea

Scientific Method

Many materials expand when heated and contract when cooled. What do you think will happen to the elasticity (stretchiness) of a rubber band when it is heated or cooled to various temperatures? Read more

Mix It Up: Transferring Heat by Convection in a Tank

Science Fair Project Idea

Scientific Method

Big, puffy, cotton-like clouds, and the bubbles in a pot of boiling water may not seem like they have much in common, but they do—both are formed by a heat-transfer process called convection. Warmed gases and liquids rise, while cooler ones fall, creating currents and mixing things up. Whether making processed foods in a factory or making plastic or metal parts, knowing how to mix up a big tank of hot and cold liquids or gases quickly is important. Engineers must rely on experimentation… Read more

Give Yourself a Lift: Lightening the Load with Pulleys

Science Fair Project Idea

Scientific Method

Before the Industrial Age, people relied on muscle power for moving and lifting heavy objects. Here's a project that shows you how you can use your head to make heavy lifting easier on your muscles–and your back! Read more

Can Cell Phones Survive a Drop Test?

Science Fair Project Idea

Engineering Design Process

Why do so many people use cell phone cases? Do cell phones really need the extra protection, or is it just because cases look fancy? In this engineering science project, you will test the durability of calculators instead of cell phones, find out if cases increase the durability of the device, and build some of your own cases that do! Read more

The Power of Your Eyes: How Vision Affects Balance

Science Fair Project Idea

Scientific Method

Staying balanced might feel simple, but there’s so much more involved than you would think! The way your body balances is actually the result of several body systems working together. Your muscles and joints provide feedback (proprioception) about where your body is in space, your inner ear senses movement and position, and your eyes give you important visual cues about your surroundings. Vision is especially important because it helps your brain judge where you are in relation to the… Read more

Applying Hooke's Law: Make Your Own Spring Scale

Science Fair Project Idea

Scientific Method

Hooke's law says that the opposing force of a spring is directly proportional to the amount by which the spring is stretched. How accurately Hooke's law describe the behavior of real springs? Can springs be used to make accurate scales for weighing objects? Spring into action and find out for yourself with this project. Read more

Engineer a Cell Phone Stand

Science Fair Project Idea

Engineering Design Process

Look around you. What types of objects do you see in the room? Furniture, lights, a computer, a fan, pencils, books, etc.? Where did they come from? Odds are you did not build them yourself. You or your parents probably bought them at a store. Before that, they were built in a factory somewhere. And even before that, they were probably designed by engineers. You might think of engineers when you think of complex machines like rockets or huge structures like bridges, but engineers also design… Read more
