About the Catapult Unit

In this unit students explored how the path of a projectile creates a parabolic shape, and how to model that shape using the mathematical techniques students learned during second semester. Students built on the concepts of intercepts, relative minimums, relative maximums, zeros of a polynomial, and end behavior during this project. To start the project students were tasked with building catapults out of popsicle sticks. Then students calculated the velocity of their projectiles (Ping Pong Balls) by measuring the height of the catapult from the ground, the amount of time the projectile was in the air after launch, with a combination of the force due to gravity. After these calculations were made a mathematical model of the path of the projectile was created.
