Your Mission �Build a catapult and defeat the neighboring camp �They have weapons, walls, and food. �All you have are your mad design skills, wooden dowels, rubber bands and some glue.

Types of Catapults Trebuchet � Throws heavy payloads from a distance � Best suited for launching payload over walls Ballista � Launches darts, bolts and spears � Best suited for launching projectiles of various sizes

Continued Mangonel � Able to control the launch angle � Best suited for destroying walls

Parts of a Catapult �Base Acts as the fulcrum �Arm Propels payload �Frame Anchors and supports the arm The fulcrum is where a lever rests

Launch Angle �You need to find the angle which launches the projectile the furthest �Is less than 90 degrees

You can build a. . .

Things to keep in mind �What are some key design goals when designing a catapult? �What shaped base should you design? �What angle should be used to launch an object the farthest?

Your project �Build a catapult that can launch a ping pong ball a minimum distance of 15 feet �You will need to test at least 3 different launch angles
