Build a Simple Walking Robot

Science Fair Project Idea

Engineering Design Process

Humans are pretty good at building vehicles with wheels, but building machines with legs that walk like us is a lot harder! In this engineering project you will build a simple robot that walks using a single motor. How fast can you make your robot go? Read more

Effect of Friction on Objects in Motion

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

M&M Survival Challenge

Science Fair Project Idea

Scientific Method

In the wild there are two types of animals: the hunters and the hunted. A good predator is always on the prowl for fresh prey. What can an animal do to stay off of the menu? Some animals have evolved to use a variety of camouflage tactics so they can fool their predators and increase their chances of survival. In this science project, you will be the hungry predator hunting for M&M® prey. But it may not be as easy as it sounds — some of your prey will be camouflaged. Will they be… Read more

How Does Color Affect Heating by Absorption of Light?

Science Fair Project Idea

Scientific Method

Why is it more comfortable to wear light-colored clothes on a hot summer day? Why wear a dark-colored jacket for early-morning fishing on a cold lake? How much difference can it make? Here's a project where you can quantify how much difference color makes for absorbing heat. Read more

Build and Test a Sun-Tracking Solar Panel

Science Fair Project Idea

Scientific Method

How can you get as much power as possible out of a solar panel, even in the morning or evening when the sun is low in the sky? With a solar tracker system! While many solar panels are fixed in place on rooftops or large ground-mounted poles, a solar tracker system is motorized and lets the solar panels track the sun through the sky during the day. Are these systems worth the added complexity? How much more power do they produce? Try this project and find out! Read more

What's the Fastest Way to Cool a Soda?

Science Fair Project Idea

Scientific Method

So you've just finished mowing the lawn on a hot summer day, and you'd like a cold, refreshing drink as a reward. You look in the fridge, and oops! it's empty. The sodas are still sitting in the cupboard, at room temperature. What's the fastest way to get that soda down to a cold, drinkable temperature with materials readily at hand? Read more

The Dynamics of a Bouncing Ball

Science Fair Project Idea

Scientific Method

Many sports use a ball in some way or another. We throw them, dribble them, hit them, kick them, and they always bounce back! What makes a ball so bouncy? In this experiment you can investigate the effect of air pressure on ball bouncing. Read more

Simple Lie Detector Test

Science Fair Project Idea

Scientific Method

Have you ever watched a great sports player and imitated his or her moves over and over again? Or have you ever felt really bad when someone got hurt or things just weren't going his or her way? If so, you might be surprised to learn that you have been practicing skills closely tied to lying! In this science fair project, you'll discover how your brain gets a workout when it moves from truth-telling to lying, and how you can detect the shift. That's no lie! Read more

Yeast Reproduction in Sugar Substitutes

Science Fair Project Idea

Scientific Method

There is nothing quite like the smell of fresh-baked bread to make your mouth water! As any baker can tell you, you cannot bake bread without yeast. Yeast actually eat sugar so that they can reproduce and make more yeast, and make bread dough rise. But can they use sugar substitutes to do this? In this science project you will get to investigate how well yeast grow with sugar substitutes as a food source. Pass the butter, please! Read more

Now You're Cooking! Building a Simple Solar Oven

Science Fair Project Idea

Scientific Method

Here is a project that uses direct solar power, gathering the sun's rays for heating/sterilizing water or cooking. It is a low-cost technology that seems to have everything going for it. Does it work? Can you find ways to improve it? Find out with this project. Read more
