Learners construct an electricity-generating wind turbine out of a plastic bottle.

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 electrochemistry activity, learners will explore two examples of electroplating.

In this activity/demo about piezoelectricity, learners discover how some crystals produce electricity when squeezed.

In this activity related to magnetism and electricity, learners discover that a magnet falls more slowly through a metallic tube than it does through a nonmetallic tube.

In this activity, learners build a simple qualitative conductivity tester with a battery, bulb and foil.

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 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 simulate the process of DNA fingerprinting by using electricity to separate colored dyes.

Learners place their hands on different metals and use an ammeter to monitor the flow of electricity from one metal to another.

Learners observe two joined glass tubes containing a conductive salt solution. Electrodes are passing an electric current through the water.

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.

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, educators can demonstrate how the nanoscale arrangement of atoms dramatically impacts a material’s macroscale behavior.

In this activity, learners make an electromagnet motor to demonstrate the most basic method of changing electrical energy into mechanical energy.

In this activity, learners make a model of a power plant that uses steam. Learners use simple materials like foil, a tin can, and a pot of water to model a geothermal power plant.

What's a Pickle-Oh? Two pieces of pickle on a stick are connected to a Pico Cricket (micro controller). When you slide the pickles apart the note changes.

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

In this activity, learners create night lights using a plastic cup, programmable PICO Cricket, tri-color LED, and sensor.

See what force a magnet has on a wire that has current running through it: will it push it, pull it, or will nothing happen? This is the foundation of a simple electric motor.
