Science Fair Project Idea
thumbnail If you ride a bike, you probably know that you have to occasionally pump up the tires to keep them fully inflated. Over a long period of time, the tires slowly leak air, so their pressure will decrease. Have you ever noticed that it is actually harder to ride a bike when the tire pressure is too low? This is because the tires are a big factor in the rolling resistance of the bike. In this sports science project, you will measure how tire pressure affects the force required to move a bike. How… Read more

Science Fair Project Idea
thumbnail Watching professional racing-car drivers compete can be thrilling. The high speeds that racing cars can reach — up to 200 miles per hour (mph) and more! — put some unique demands on the vehicles. For example, to withstand high temperatures, the tires must be inflated with nitrogen gas, instead of air as with normal car tires. This enables the drivers to have better control over steering their cars as they race around the track. In this sports science project, you will inflate… Read more

thumbnail Do you love roller coasters and other kinds of exciting rides? Are you a thrill-seeker? Well, this is the science fair project for you! What makes a ride so thrilling that people want to ride it over and over again even though it scares them? Is it the speed, the twists and turns, the vertical drops? In this science fair project, you will build and use an accelerometer to figure out what makes a roller-coaster ride worth standing in line for. Oh, and if Mom and Dad ask what an amusement park… Read more

Science Fair Project Idea
thumbnail Have you ever played paintball with your friends? Wonder how you can improve your game? Paintball guns use compressed gas to shoot paint-filled pellets at high speed, and with good accuracy. The flight path of the ball is determined by its speed and the angle at which it is shot, relative to the ground. In this sports science fair project, you will explore the ballistics of paintballs, focusing on how drag and other factors affect the results. Read more

Time Required Average (6-10 days)
Prerequisites You should have access to a paintball gun, be familiar with how to shoot it safely, and have access to an open area where you can shoot it. This project has a fairly involved procedure, since you are measuring several parameters (velocity, time of flight, distance) and also comparing these measurements to what you would expect based on calculations. Feel free to customize the procedure based on your interests.
Material Availability Specialty items: You will need access to a paintball gun and accessories, including safety gear for you and for three helpers, as well as an instrument to measure velocity of the paintballs. See the Materials and Equipment list for details.
Cost Average ($50 - $100)
Safety Minor injury is possible, so wear eye protection. Adult supervision is required.

Skateboarder alert: Extreme performance needed in this project. Dude, you can cruise and carve while you investigate which skateboard wheels produce the fastest (and slowest) rides on your terrain in these experiments. You pick the wheels and design the tests you think will produce the most extreme results for speed and turns. Do this project and you can work on your ride and learn some science about the speed, spin, and design of skateboard wheels. Read more

thumbnail While watching an ice hockey game, have you ever wondered what differentiates a good player from a great player? For sure, the great player is athletically superior to the good player. But maybe it is a combination of athleticism and equipment. Maybe a great player knows which hockey stick is best for him or her. Hockey players can choose to play with hockey sticks with different flexibilities or "flex." In this science fair project, investigate how stick flex affects shot accuracy and speed.… Read more

Science Fair Project Idea
Solar cells are devices that can be used as a source of power when there is light shining on them, but they stop producing energy when they are not in the light. One way to store the solar energy for later use is to use a solar cell to charge something called a capacitor. The capacitor stores the energy as an electric field, which can be tapped into at any time, in or out of light. In this electronics science project, you will use parts of a solar car to experiment with the energy storage… Read more
