In this chemistry demonstration, learners will discover that phenolphthalein is a chemical that displays different colors depending on the acidity or basicity of the environment.

The "Rocket Reactions" activity is an exciting way to learn about how materials interact, behave, and change.

In this activity, young learners investigate magnets. Learners discover that some magnets are stronger than others and that magnets have north and south poles.

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

In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, size, and bounce height.

In this activity about magnetism (page 15 of the PDF), learners will explore how opposite and similar magnetic poles affect a swinging (pendulum) magnet.

In this activity about transfer of energy, learners get to build their own catapult using nothing more than a plastic spoon and some tape.

In this hands-on activity, learners determine the types of chemical reactions achieved when combining different household products.

During this activity, learners will make different versions of "ooze" using varied proportions of detergent and glue.

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

Learners observe and compare the sizes of three toy “growing” crocodiles made from water-absorbent polymers. One is it its original state, dry, hard, and about 10cm long.

Glare from the sun and ripples from the wind can make it hard to see what's below the surface of a body of water.

Learners mix liquid water with solid cornstarch. They investigate the slime produced, which has properties of both a solid and a liquid.

In this physics activity, learners experiment with the attractive and repulsive power of magnets.
