In this physics activity, learners build their own rockets out of film canisters and construction paper.

In this activity, learners examine the properties of different seaweeds, investigate what happens when powdered seaweed (alginate) is added to water, and learn about food products made with seaweed.

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

In this chemistry activity, learners use the lowered freezing point of water to chill another mixture (ice cream) to the solid state.

This lesson (on pages 15-24 of PDF) explores how sound is caused by vibrating objects. It explains that we hear by feeling vibrations passing through the air.

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.

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

"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, learners build handheld rockets and launchers out of PVC pipes and plastic bottles. Use this activity to demonstrate acceleration, air pressure, and Newton's Laws of Motion.

In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.

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