In this activity, learners use a compass, powerful magnet, and copper magnet wire to build a special generator known as a dynamo.

In this activity related to magnetism and electricity, learners observe as two parallel, current-carrying wires exert forces on each other.

In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.

In this activity, learners explore the difference between compact fluorescent light (CFL) bulbs and traditional incandescent bulbs.

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

Cool off in the heat with this project! Learners use simple materials to build a fan that runs on a motor.

In this technology activity, learners build an "alarming" doormat to keep siblings out of their rooms. Use this activity to teach learners about circuits, switches, and sensors.

In this activity, learners build a tiny but powerful flashlight out of simple materials. Use this activity to introduce learners to electrical circuits and conductivity.

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

In this activity, learners demonstrate and discuss simple circuits as well as the differences between parallel and serial circuit design and functions.

In this activity, learners build a mini dancing robot. This engineering activity introduces learners to electricity, circuits, switches, conductivity, and motors.

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 how a flashlight works, showing the electric circuit and switch functions of this everyday household item.

In this data analysis and environmental science activity, learners evaluate the feasibility of wave energy as a practical alternative energy source using ocean observing system (OOS) buoys.
