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 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 design challenge activity, learners use two helium-filled balloons to build a blimp that can travel in a straight path across the room.

Agriculturalists have long considered mushroom growing a challenge, largely because you need a piece of benchtop equipment known as a laminar flow hood.

This lesson challenges groups of learners to design and construct a wind generator with the most electrical output.

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.

Learners will build a lung model to understand how their lungs and diaphragm work to make them breathe.

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.
