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

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

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

In this activity, learners create painting machines that can paint moving forwards and backwards.

Learners build a wind turbine and test it to see how much energy is created.

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.

Using electrolysis, learners produce hydrogen gas and oxygen gas from water molecules in a solution.

This is a series of demonstrations about different electrical and magnetic phenomena.

In this activity, learners explore the concept of how engineering solved the problem of human/computer interface.

In this activity, learners explore computer programming and the impact of computers on society. Learners build and test a program to turn a light on and off using an Arduino board.

In this activity, learners apply Ohm’s Law to construct voltage divider circuits. Learners discover how to read resistor codes and calculate resistor values.

In this activity, learners explore chemical engineering and how the processes of chemical plating and electroplating have impacted many industries.
