This experiment describes how to create a "dribble bottle" which only leaks water when the cap is unscrewed. The full water bottle has a small hole made with a push pin.

In this activity, learners will create a model rocket out of an inflated balloon attached to a straw on a taught string.

In this design challenge activity, learners make a balloon hover at eye level for five seconds, and then make it move by creating air currents.

This three-part activity shows learners how to build three meteorology tools: a wind vane, a rain gauge, and a barometer.
