Learners assemble a hot-air balloon from tissue paper. The heated air (from a heat gun) inside the balloon is less dense than the surrounding air and causes the balloon to float.

In this activity, learners work in teams to investigate the relationship between mass, acceleration, and force as described in Newton's second law of motion.

In this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.

MarsBound! is an engineering simulation activity in which learners use realistic techniques to plan a mission to Mars.

In this physics activity, learners will explore buoyancy.
