In this activity, learners construct their own small catapults using simple materials. Learners follow visual instructions to build their launching device.

In this activity, learners discover how NASA engineers develop experimental aircraft.

Build a catapult that transforms the potential energy of a twisted rubber band into kinetic energy. Experiment with design variations so that you can hit a target with a projectile.

In this dynamic activity, learners build a catapult that launches projectiles, such as marshmallows.
