Learners observe projectile motion by launching wooden balls off of a table top. They set up a rubber-band launcher so that each ball experiences a consistent amount of force.

Learners build simple catapults and use them to launch cotton balls.

In this activity, learners make a simple spring-like scale using a rubber band instead of a spring, and calibrate the scale in newtons (N).

Learners drop two different masses of play dough and observe how long it takes them to hit the ground.
