If a sailboat is stranded because there is no wind, is it possible to set up a fan on deck and blow wind into the sail to make the boat move?

In this activity, you'll make an electric motor--a simple version of the electric motors found in toys, tools, and appliances everywhere.

In this demonstration, cook a cake using the heat produced when the cake batter conducts an electric current.

In this activity, high voltage is applied across a pickle to emit a yellow glow. This activity should only be conducted by skilled adults and is best suited as a demonstration.

In this activity about electricity, learners explore what happens when you blow a fuse.

In this activity about electricity and magnetism, learners examine what happens when a magnet exerts a force on a current-carrying wire.

In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.

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 create a tiny electric, motorized dancer. Learners use the interactions of magnetism and electric current to make a wire spin, while displaying the Lorentz Force in action.

Construct a simple battery that's able to power a small light or motor out of foil, salt water, and charcoal. A helpful video, produced by the Exploratorium, guides you along on this activity.

Make your own simple speaker so you can listen to your favorite radio station. Just wind a coil, attach it to a piece of cardboard or Styrofoam, hold a magnet nearby, and listen.

Make your own speaker with a magnet, wire, and paper cup! If you have a radio with a headphone plug and an old pair of headphones, this is a great tinkering activity.

In this activity, learners light an LED with five cents. Learners use two different metals and some sour, salty water to create a cheap battery.
