Use a homemade potato launcher to explore air pressure. This activity includes simple instructions on how to build a homemade propulsion pipe using pipe, a wooden dowel and duct tape.

In this experiment, learners use a blow dryer and water bottle to observe and record changes in air pressure caused by changes in temperature.

In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.

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.
