In this physics demonstration, learners will be surprised when a lemon slice appears to magically levitate within a pint glass.

In this meteorology activity, learners build weather vanes using straws, paperclips, and cardstock.

Learners develop an understanding of air pressure in two different activities.

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.

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.
