How Fatigue Changes Balance

Science Fair Project Idea

Scientific Method

Balance is one of the most important parts of how our bodies work. Even standing still requires the brain, muscles, eyes, and inner ears to coordinate perfectly. But what happens when you get tired—even just a little bit—from something like dancing, running, jumping in place, or doing step-ups for a short period of time? Many scientific studies show that fatigue—both mental and physical—can make balance worse. For example, after short bursts of physical activity, people… Read more

How Shoe Tread Affects Traction

Science Fair Project Idea

Scientific Method

Have you ever noticed that some shoes grip the ground better than others? The pattern and design of a shoe’s tread can affect how slippery it is on different surfaces. You can test shoes with different tread patterns—like flat, ridged, or patterned—to see which design provides the best grip. By dragging a shoe along a surface with a spring scale at a constant velocity, you can measure how much force is needed for each shoe to slide on various surfaces. With this knowledge, you… Read more

Jumping Distance

Science Fair Project Idea

Scientific Method

Mike Powell of the United States currently holds the world record for the long jump at 8.95 meters, which is almost 30 feet! How did he jump so far? In this experiment, learn how a long jumper uses momentum from running to jump farther than the competition. Read more

Have you ever played mini golf? It might seem like just a game, but there is a lot of science behind it! Learn about the physics behind a rolling, bouncing mini golf ball and design your own mini golf course in this fun science activity. Read more

Popping an Ollie: How Skateboarders + Physics = A Really Cool Trick

Science Fair Project Idea

Scientific Method

Have you ever seen a skateboarder jump over an obstacle or slide down a railing? It looks like they are defying the laws of physics when they perform these tricks. It looks like it, but that's not the case. Physics describes the motion of objects and it is a skateboarder's best friend! All of these tricks can be explained by physics. In this sports science fair project, you will learn how speed affects "popping an ollie." The ollie is a basic skateboarding trick, and it's the first step to more… 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

Should We Walk Like Penguins? How Age Affects Your Stride

Science Fair Project Idea

Scientific Method

Watch out for that ice! When winter weather makes sidewalks icy, many people slip and fall. One tip doctors give is to walk like a penguin. That means pointing your feet slightly outward, keeping your center of gravity over your feet, and taking short, careful steps. Research has shown that these changes in stride and posture help people stay stable and avoid falls. These tips are especially helpful for older adults, who are more at risk of falling due to a decline in their balance as they… Read more
