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

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?

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 investigate the different salinity levels of oceans, rivers and estuaries.

In this electrochemistry activity, learners will explore two examples of electroplating.

In this activity, learners use a flexible magnet as a model for a scanning probe microscope (SPM). They learn that SPMs are an example of a special tool that scientists use to work on the nanoscale.

In this activity, learners use a laser pointer and two small rotating mirrors to create a variety of fascinating patterns, which can be easily and dramatically projected on a wall or screen.

In this activity, learners explore how wind energy can be generated on both a large and small scale.

In this activity, learners investigate various appliances and electronics, discovering how much energy each uses and how much carbon dioxide (CO2) is released to produce that energy.

Use a Pico Cricket (micro-controller) to animate your art! You can program a Pico Cricket to make your art spin, light up, or make music.

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

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.

In this activity, you take regular dominoes, and turn them into conductive switches that can turn on a LEGO RCX block or Pico Cricket (micro controller). LEGO RCX block or Pico Cricket is required.

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