Science Fair Project Idea
In baseball, coaches use hit charts to track the results of every hit each player makes, giving a measure of the player's performance. Have you ever wondered what things affect where a baseball goes when a player hits it with a bat? In this project you will set up an experiment to hit a ping pong ball in a controlled manner using a toy catapult, then learn about the physics of baseball by making your own hit chart. Read more

Science Fair Project Idea
In physics class, you have probably rolled your eyes at some point after being assigned a "projectile motion" homework problem where you use equations to predict how a ball will move through the air. This experiment will show you just how fun that problem can be by using a real catapult to launch a ball and videotaping it as it flies along its path. Then, you will analyze the video and compare it to what the equations predicted. If you have ever wondered if those equations in your physics… Read more

Time Required Average (6-10 days)
Prerequisites This project requires a basic understanding of algebra, trigonometry (sine and cosine functions), and physics (kinematics—two-dimensional projectile motion), or the willingness to learn about these subjects on your own.
Material Availability This project requires access to a video camera (not included in the cost estimate) and the purchase of a catapult kit. (See the Materials and Equipment list for details.)
Cost Average ($40 - $80)
Safety Minor injury possible. Never aim the catapult at anyone, and keep your hands and fingers clear of the moving catapult arm when launching the catapult.
Science Fair Project Idea
Did you know that throwing, kicking, and punting a football all involve the science of projectile motion? A star NFL® quarterback, kicker, and punter each need to have a very good understanding of how a football moves through the air in order to help them win games. In this science project, you will set up a rubber band-powered catapult to represent a field goal kicker, and study how changing the distance from the goalposts affects how hard it is to accurately kick a field goal.

Science Fair Project Idea
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

Safety Do not aim the catapult at breakable objects or people; minor injury possible.
Science Fair Project Idea
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

Science Fair Project Idea
The electricity in your home probably comes from a power plant, but did you know that you can actually generate your own electricity? Wondering what it would take to light up a small light? This is your chance! In this electronics science project, you will build your own electric generator and investigate how to light up not just one, but two lights. Read more

Time Required Average (6-10 days)
Prerequisites You should have the patience and dexterity to coil several layers of wire neatly (or find someone who can help you). You will also need to hook up a basic circuit. Understanding electric circuits is not a prerequisite for this science project, though it will enable a deeper understanding of the electric generator.
Material Availability A kit containing all the specialty items needed for this project is available from the .
Cost Low ($20 - $50)
Safety Neodymium magnets are very strong. Follow the safety guidelines in the Procedure for working with these magnets.
Science Fair Project Idea
The electricity you use to power everyday devices is generated by electrical generators. These fascinating and powerful machines rely on magnets to function. Though they might seem extremely complicated, once you finish this science project, you will understand how, why, and when they generate electricity. You will build your own generator, make small changes in how exactly the magnets are placed, and test when moving magnets generate electricity. Read more

Science Fair Project Idea
If you have ever tried to hit a target (such as a trash can) with a wad of paper, you know that aim is everything. But it is not always easy to get it right every time! Missing is not that big a deal with a wad of paper, but what if you were in an invading army in the Middle Ages, using a catapult to hurl huge stones and knock down castle walls? For a successful invasion, it would be important to know exactly how far, and how reliably, a catapult could launch a projectile. In this project you… Read more

Science Fair Project Idea
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

Science Fair Project Idea
You may be familiar with permanent magnets—the kind that hang on a refrigerator. But did you know that other magnets, called electromagnets, can be turned on and off? When turned on, electromagnets act just like permanent magnets, but if you turn them off, their magnetic properties disappear. Electromagnets are an important part of many electronic devices, like motors, loudspeakers, and hard drives. You can create an electromagnet with a simple coil of wire and a battery. In this project,… Read more
