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

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.

In this activity, learners simulate the process of DNA fingerprinting by using electricity to separate colored dyes.

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.

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

In this technology activity, learners light up the room with electrifying play dough creations. Learners use conductive and insulating homemade play dough to build simple circuits.

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

In this technology activity, learners build simple circuits, design soft circuits using conductive thread, and then sew switch-activated circuits.

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.

Learners use engineering design principles to construct and test a fully solar-powered car. Solar car kits usually include a photovoltaic cell and motor; some include a chassis as well.

In this activity, learners build a recording timer made from simple materials (e.g., small dc motor, sharpie pen, craft sticks, adding machine paper tape, etc.).

In this engineering activity, learners will get acquainted with the basics of wind energy and power production by fabricating and testing various blade designs for table-top windmills constructed from

A magic lantern is a light that projects an image onto a screen.
