In this activity, learners investigate the speed of chemical reactions with light sticks. Learners discover that reactions can be sped up or slowed down due to temperature changes.

In this physics activity, learners construct a small-scale version of a classic carnival game.

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.

This activity about density provides instructions for making a miniature "lava lite" with just salt, oil, water, and food coloring.
