In this activity, learners build a game that tests their steadiness. Learners construct the game board by setting up an electrical circuit and a wand.

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

Learners use shop tools and various materials to construct a magnetic spinner and a compass.

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.

In this activity, learners build an electric two-paddle boat using paint paddles, plastic knives, and empty water bottles.

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

In this activity, learners explore how various energy sources can be used to cause a turbine to rotate.

Before there were clocks, people used shadows to tell time. In this outdoor activity, learners will discover how to tell time using only a compass, a pencil, a handy printout, and a sunny day.

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.

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

In this activity, learners incorporate a simple switch into a battery/bulb circuit. Learners will use their knowledge of circuits to design and make their own switches using common materials.

In this activity, learners explore electronic communication, the Morse Code system, and advances all the way through text messaging. Learners build a simple circuit, send messages to one another.

In this activity, learners explore motion, energy, and electricity by constructing bottle cars that run on motors.

This activity guide includes instructions on how to build a "Shake Table" by mounting an eccentric mass (off center) on the shaft of a small dc motor.

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

In this activity/demo, learners investigate biobarcodes, a nanomedical technology that allows for massively parallel testing that can assist with disease diagnosis.

In this activity about electricity, learners build and test a paper clip switch to turn on a light bulb.
