This fun and simple hands-on astronomy activity lets learners explore model planets (that they or an educator will create), using methods NASA scientists use to explore our Solar System.

Learners investigate a pre-constructed mystery tube to determine its interior mechanism.

In this activity, learners are challenged to design a planktonic organism that will neither float like a cork nor sink like a stone.

In this activity, learners use three types of cheesy snacks--cheese balls, cheese puffs, and Cheetos--to learn about polymers.

In this activity, learners use molecular model kits to construct familiar molecules like lactose, caffeine, and Aspirin.

Water on Earth is in lakes, the ocean, rivers, underground, and frozen glaciers.
