The Exploratorium

Learn about chemical reactions by making a Bubble Bomb, a plastic bag you can pop with the power of fizz.

This activity explores the concept of center of gravity by having learners build a Jitterbug--a motorized toy that seems to dance--using a recycled CD and a DC motor.

In this activity, learners explore how two cylinders that look the same may roll down a ramp at different rates.

In this optics activity, learners discover that not all shadows are black. Learners explore human color perception by using colored lights to make additive color mixtures.

In this geometry activity, learners explore networks painted on playgrounds, such as a four square court, and draw their own.

This hands-on activity shows you how to build basic architectural shapes out of toothpicks and gumdrops.

With little more than a flashlight, a straw, and a plastic lid, make an observatory so you can see the amazing colors in bubbles.

In this activity and demonstration about electricity and magnetism, learners observe how the current generated when one copper coil swings through a magnetic field starts a second coil swinging.

In this activity, learners create a large film of soap and experiment with what can and cannot pass through it.

In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.
