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.
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.
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.
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.
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…
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…

Learn about potential and kinetic energy the fun way—by launching ping pong balls across the classroom with a catapult!
NGSS Performance Expectations:
MS-PS3-5. Construct, use, and present arguments to support the claim that when the kinetic energy of an object changes, energy is transferred to or from the object.
