Learners observe a simple balloon model of an electrostatic precipitator. These devices are used for pollutant recovery in cleaning industrial air pollution.

In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.

Why is ocean water sometimes the warmest when the average daily air temperature starts to drop? In this activity, learners explore the differing heat capacities of water and air using real data.

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

Learners observe and discuss a vacuum cleaner as a model of a baghouse, a device used in cleaning industrial air pollution.

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

In this activity, learners use simple items to construct a device for indicating air pressure changes.

In this activity, learners use simple items to construct a device for indicating air pressure changes.

In this two part activity, learners become draft detectives by constructing their own draft catchers to detect drafts around windows or doors.

In this design challenge activity, learners use a balloon and other simple materials to design an air-powered rocket that can hit a distant target.

In this activity, learners explore clouds and how they form.

In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.

In this activity, learners explore rocketry and the principals of space flight.
