In this physics activity, learners use square blocks to explore how towers fall. Learners attach a piece of string to the side of a block and then construct a tall tower on top of this base block.

In this activity, learners create a tornado in a bottle to observe a spiraling, funnel-shaped vortex. A simple connector device allows water to drain from a 2-liter bottle into a second bottle.

In this engineering activity, learners design parachutes to give toy figures safe landings. This activity is great for practicing an important STEM skill--changing only one variable at a time.

Build a car that runs on air. Using household materials, experiment with the power of air to create thrust powerful enough to move a homemade car.
