In this activity, learners use a simple trick of perspective to dress friends in tiny cutout clothing. Learners make tiny pants out of card stock and tape them to the end of a stick.

In this simple activity, learners create an electroscope by sticking two short pieces of magic tape together and then pulling them apart to find the sign of the charge on an unknown charged object.

In this activity, learners stain fabrics--on purpose!

In this activity, learners explore liquid crystals, light and temperature. Using a postcard made of temperature-sensitive liquid crystal material, learners monitor temperature changes.

In this activity, learners will discover how to find the "sweet spots" on a baseball bat. Whenever an object is struck, it vibrates in response.

In this activity, learners experiment with surface tension using everyday household items such as strawberry baskets, paperclips, liquid dish soap, and pepper.

In this weather-related activity, learners make a portable cloud in a bottle.

In this activity, learners build a simple electrolysis device. Then learners use an indicating solution to visualize hydrogen and oxygen molecules in water.

In this activity, learners explore how pictures change in curved mirrors. Learners make cylindrical mirrors by wrapping Mylar around soda cans.

In this activity, learners will observe laminar and turbulent flow of water using only a plastic bottle, liquid hand soap, food coloring and water.

In this activity, learners model directed evolution by making paper fly. Learners construct and fly paper airplanes.

In this activity, learners play with a fuzzy-colored dot that has no distinct edges seems to disappear. As learners stare at the dot, its color appears to blend with the colors surrounding it.
