Football Field Goals: Going the Distance
Science Fair Project Idea
Scientific Method
When watching a football game, have you ever wondered why some kicks lead to a successful field goal and others do not? There are a lot of variables at play in a game of football, and many of them are related to physics. One variable that can affect whether a field goal is successful is distance. In this science project, you will explore how field goal success rate is affected by distance from the goalposts. What will be the best distance for you to kick some field goals? Grab a football, head… 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
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
Bouncing Basketballs: How Much Energy Does Dribbling Take?
Science Fair Project Idea
Scientific Method
Playing basketball can be hard work. Players not only constantly run around the court, but just dribbling the basketball takes a lot of effort, too. Why is that? It has to do with how the basketball bounces. When the ball hits the court, its bounce actually loses momentum by transferring some of its energy into a different form. This means that to keep the ball bouncing, players must continually put more energy into the ball. In this sports science project, you will determine how high a… Read more
Basketball Physics: Where Does a Bouncing Ball's Energy Go?
Science Fair Project Idea
Scientific Method
Have you ever noticed that when you drop a basketball, its bounce does not reach the height you dropped it from? Why is that? When a basketball bounces, such as on a basketball court, its bounce actually loses momentum by transferring energy elsewhere. This means that to dribble the basketball, players must continually replace the transferred energy by pushing down on the ball. But what happens to the "lost" energy? As we know from physics, energy is not really lost, it just changes form. One… Read more
Heart Health: How Does Heart Rate Change with Exercise?
Science Fair Project Idea
Scientific Method
Your heart starts beating before you are born and keeps right on going through your whole life. Over an average lifetime, the human heart beats more than 2.5 billion times. Keeping your heart healthy means eating right, not smoking, and getting regular exercise. Which of your favorite physical activities give your heart the best workout and help keep it fit? In this science project, you will use a smartphone equipped with a sensor app to visualize your heart rate and find out which… Read more
Nothing But Net: The Science of Shooting Hoops
Science Fair Project Idea
Scientific Method
Swish! What a great sound when you hit the perfect shot and get nothing but net. Here's a project to get you thinking about how you can make that perfect shot more often. Read more
Basketball: Will You Bank the Shot?
Science Fair Project Idea
Scientific Method
You are right next to the basket and someone passes you the ball. Will you go for a direct shot or will you use the backboard and take a bank shot at the basket? Would different positions on the court give you a higher chance of making a shot using the backboard than others, even when keeping the distance from the hoop the same? In this science project, you will build a scale model and test different positions on the court to determine if one results in a better chance of making a bank shot… Read more
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
Soccer: Geometry of Goal-Scoring
Science Fair Project Idea
Scientific Method
Block off one-third of a soccer net with a cone, 5-gallon bucket or some other suitable object. Shoot into the smaller side from a set distance, but systematically varying the angle to the goal line. Take enough shots at each angle to get a reliable sample. How does success vary with angle? For a basic project: How do you think your success rate will vary with angle? Draw a conclusion from your experimental results. A bar graph showing success rate at different angles can help to… Read more
