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

Learners build a simple aneroid barometer to learn about changes in barometric pressure and weather forecasting. They observe their barometer and record data over a period of days.

In this activity, learners explore how parachutes are used to slow down moving objects. Learners work in teams of "engineers" to design and build their own parachutes out of everyday items.

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

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