Science Fair Project Idea
thumbnail Have you ever seen a "Hail Mary" football pass, where the quarterback tries to throw the ball as far as possible to reach the end zone and score a touchdown? Or a last second game tying soccer goal from midfield? How far the ball will go does not just depend on how hard a player throws or kicks it; it also depends on the angle at which the player launches the ball. In this sports science project, you will investigate how launch angle affects the distance that a ball travels by filming… Read more

Science Fair Project Idea
thumbnail Did you know that not all trains run on tracks? Some of the world's fastest trains are magnetic levitation trains (maglev). This means that the carriage of the train is suspended over the rails with no support, but only with magnetic fields! There is a physical explanation for magnetic levitation, and if you would like to learn more about magnetism and current, this is a science fair project that you must try! Read more

Science Fair Project Idea
thumbnail If you were in a raiding army in the Middle Ages, a catapult would come in mighty handy for taking down castle walls. But only if you could aim it reliably! With this science project, you will try your hand at catapult technology. Using a rubber-band-powered catapult you will send ping pong balls flying through the air. The catapult's design makes it easy to measure and repeat how hard the ball is launched and its direction, so you can find the right catapult settings to hit the target reliably. Read more

Science Fair Project Idea
thumbnail The movement of satellites is intriguing, but how do they orbit the way they do? Aerospace engineers run calculations and set up computer models to help them predict how satellites move in space, but in this astronomy science project, you will create a physical model with marbles, clay, and a cookie sheet to help you study how satellites move in space and learn from your observations.

Science Fair Project Idea
thumbnail Have you ever had fun playing with sand and water, observing how little rivers you create carve their way down to the lowest point of the sandbox, backyard or beach? Some meander, others braid, and some carve a path straight down. Hyrdologists (or scientists who study water) do very much the same thing! Only they set up the model in a particular way, so observing their mini-rivers helps them answer questions about how water flow affects the environment. In this geology science project, you… Read more

Science Fair Project Idea
thumbnail If you've ever played or watched basketball, you might already know that your chances of successfully banking a shot on the backboard are higher in certain positions on the basketball court, even when keeping the distance from the hoop the same. Ever wondered what would account for this? Do you think you could actually explain this using geometry? This science project will put your knowledge of geometry and algebra to good use. You will calculate and quantify how much more difficult it is to… Read more

Science Fair Project Idea
thumbnail You may have seen movies or read books where armies in medieval times catapulted large rocks or other objects at castles (or each other!). These armies used different types of catapults to accomplish different goals — for example, launching things over or into castle walls to knock them down. In this experiment, you will use a ping-pong ball catapult to lay siege to a "castle" and find the right settings to hit your targets. Read more

Safety Minor injury possible. Keep your fingers clear when launching the catapult. Do not aim the catapult at people.
Science Fair Project Idea
thumbnail In the Science Buddies project , you can learn about the basics of magnetic induction, or how moving magnets can be used to generate an electric current. The detailed physics of how a changing magnetic field can induce an electric current are described by Faraday's law and Lenz's law (see the Bibliography for more information about these two laws). For a more advanced version of the Human-Powered Energy project idea, try setting up an experiment to prove or demonstrate these two laws,… Read more

Safety Neodymium magnets must be handled carefully. Please see the detailed warnings in the Procedure.
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
Sports_p054
+ More Details
- Less Details
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.

thumbnail Here is a project that is almost like a magic trick: with a strong magnet and a simple apparatus you can build yourself, you can make a coin "walk" up and down a wire coat hanger! This project is an interesting way to learn about the distance over which magnetic forces act on magnetic materials. Read more
