This activity was designed for blind learners, but all types of learners can use it to build and examine a basic electrical circuit.

In this activity, learners will build a simple electromagnet. They will test variables that would make the electromagnet stronger.

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.

Learners build a simple one-cell battery and use an ammeter to measure the flow of current.

In this activity, learners explore electronics and motion by making a Scribbling Machine, a motorized contraption that moves in unusual ways and leaves a mark to trace its path.

This is an activity that demonstrates how batteries work using simple household materials. Learners use a pickle, aluminum foil and a pencil to create an electrical circuit that powers a buzzer.

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

In this activity about chemistry and electricity, learners form a battery by placing their hands onto plates of different metals.

The Let's Do Chemistry "Build a Battery" activity lets participants learn how batteries work and how materials behave, change, and interact by building their own simple battery out of metal and felt w

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

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

Learners make a simple battery out of "sandwiches" of aluminum foil, pennies, and a salt water-soaked paper towel.

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

In this activity, Frankenstein's lab is running out of electricity! Learners use fruit to help Igor find a temporary source of energy to turn on a light.

In this design challenge activity, learners design and build a circuit: an "electric highway" that connects a battery and buzzer at least three feet apart using four types of materials.

Learners observe an electrochemical cell constructed from a small jar containing zinc and copper strips immersed in separate solutions. The strips are connected to a motor that turns a small fan.

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.
