Algebra one students are completing a catapult activity that requires them to collect data relating to projectile motion. Projectile motion is a type of motion in which an object is thrown and moves along a curved path due to gravity. In the activity, students will use a catapult to launch a Koosh ball and observe its motion. They will then apply a mathematical model to describe this motion and use that model to predict the height of the projectile at various points along the path. Watch the video of Mr. Vokes and his students launching their Koosh balls and collecting their data.
