In this activity, groups cut out and sort cards showing items recovered from a crash landing on the Moon. The 12 items range from food and water to rope and matches to a self-inflating life raft.

In this activity, learners make pykrete by freezing a mixture of water and a material like cotton wool, grass, hair, shredded paper, wood chips, or sawdust.

In this activity, kids make and play with Ooze before testing the material in an egg drop!

This activity models some of the ways natural processes, such as erosion and sediment pollution, affect Earth’s landscape.

Learners experiment with a commercial photo-sensitive paper (Sunprint® or NaturePrint® paper). They place opaque and clear objects on the paper and expose it to bright light, observing the results.

"Sublimation Bubbles" allows learners to explore how some solid materials, such as dry ice, can phase change directly from their solid to gaseous form.

In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.

In this activity, learners explore chemistry and the microbial world by making their own sourdough starter and bread at home using only flour and water.

In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.
