In this activity, learners build a simple "rocket" with ordinary household materials to demonstrate the basic principles behind rocketry and the principle of reaction.

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, 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 activity, learners of all ages can enjoy experimenting with ice. Try this experiment at the kitchen table or in the great outdoors to encourage budding scientists to experiment with ice.

Learners place water and part of an antacid tablet in a film canister. The reaction creates a gas reaction that launches the film canister like a rocket.

Everybody loves bubbles, and this is the best bubble recipe ever!

In this engineering design challenge, learners make a bird and then control its flight with attached strings.

This activity shows you how to make amazing crystal spikes using Epsom salt and the sun.

This hands-on activity lets participant explore chemical reactions as they create a soda explosion with lots of bubbles. The bubbles in soda are made of carbon dioxide gas.

This warm weather activity introduces learners to the impact trees have on blocking the sun's heat and reducing temperature on the Earth's surface.

In this activity, learners investigate how different materials repel or absorb water. Learners use spray bottles to explore how everyday items like sponges, cardboard, feathers, etc.

In this activity, learners explore properties of water and watch evaporation happen by "painting" with water in the sun.

In this activity, learners investigate and compare the rate of drying in different conditions.

In this activity on page 24, learners perform experiments to examine whether or not trash can float, blow around, or wash away.

In this meteorology activity, learners build weather vanes using straws, paperclips, and cardstock.

In this activity, learners work in groups to build simple solar stills filled with salt water. After the stills are complete, learners observe what happens when they place the stills in the sun.

In this activity, learners build a kite out of paper, change it, and try to make it fly even better. With their new knowledge of kite making, students can then go on to create their own kite designs.

This activity gets learners looking at 6-sided shapes in nature, including the cells of a beehive, as well as other shapes.

In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.

In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.
