In this activity, learners observe what would happen to their bodies if they went to outer space without a space suit.

In this physics activity, learners recreate Galileo's famous experiment, in which he dropped a heavy weight and a light weight from the top of the Leaning Tower of Pisa to show that both weights fall

In this engineering design challenge, learners build an octopus-inspired suction pad that can grab an object and hold it tightly in the air.

This activity explores the basic workings of a siphon, which is the core technology that makes toilets work.

In this activity, learners explore how engineers have met the challenge of keeping foods, liquids, and other items cool.
