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.

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

In this activity, learners build simple alarms that they can attach to anything, such as a drawer or doorway. This activity introduces learners to electricity, circuits, and currents.

In this activity, learners explore conservation of energy by experimenting with a solar cell light device.

In this activity, learners create a battery from fruit. This activity helps learners explore electricity, electrochemistry, and series circuits as well as the process of scientific inquiry.

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.

In this design challenge activity, learners build a car that uses a battery-operated motor to "drive" at least ten feet.

In this activity, learners construct bug models that "jitter" all over the table with just a battery, motor, and counterweight.
