Explore the effects of gravity on a slowly falling object: a parachute you make out of plastic bags, string and stones.

In this activity (7th activity on the page), learners use their sense of hearing to find a "sound match." Learners shake containers filled with items like dry seeds, sand, beans, etc.

In this chemistry activity, learners use guar gum to make slime. Use this activity to introduce learners to polymers, viscosity, and colloids.

In this activity, learners make plates levitate! Learners build "hovercrafts" using simple materials to explore friction and motion.

In this activity, learners will become an engineer by designing and engineering a miniature parachute.

In this activity, learners explore why they can see colors in bubbles and why they change.

Learners build a can that automatically returns after being rolled away. The can has a rubber band inside that stores energy as the can rolls one direction.

In this physics activity, challenge learners to make and race a balloon-powered car. Learners construct the body out of a paper cup, wheels out of wooden spools. and fuel tank out of a balloon.

In this activity, learners will explore the insect life cycle by making a model.

Learners experiment with a commercially available liquid-crystal coaster. They warm the material with their hands for varying lengths of time and observe the changing colors that result.

In this activity, learners create a toy that demonstrates the First Law of Thermodynamics or the Law of Conservation of Energy.

Build a glider that uses the same physics as a curve ball, for less than a dime.

In this activity, learners construct a paper glider to experiment with aerodynamic forces.

In this math game, learners solve a mind-twisting puzzle using dominoes. Use this activity to help learners practice counting, adding, and solving problems.

Learners use a commercially available toy to experiment with density. They fill a chamber in the toy submarine with baking powder and release it into a tank of water.

In this activity, learners will experiment with the physics of forces - kinetic energy and friction while making a moving toy woodpecker.

In this activity, learners sort different natural phenomena into categories (they occur on Earth, on the Moon, or on both), and then model how energy moves during a quake using spring toys.

In this activity, learners will experiment with the physics of flight by making a gliding contraption with strange looking wings. The activity explores flight with connections to the natural world.

In this math activity, learners pretend there is a special store that lets you pay for toys by their height in pennies.

In this math activity, learners pretend there is a special store that lets you pay for toys by their weight in pennies.
