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 a simple qualitative conductivity tester with a battery, bulb and foil.

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

In this engineering design challenge, learners make a bubble maze that allows bubbles to move through a series of “on” and “off” switches.

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.

This activity (on page 3 of the PDF under GPS: Body Electricity Activity) is a full inquiry investigation into conductivity.

In this activity, learners explore an everyday situation, where either of two or more buttons can ring a buzzer.

In this activity, learners explore the concept of conducting or insulating electricity.

In this activity, learners will listen to as many radio stations as possible to discover that AM radio signals can travel many hundreds of miles at night.

Learners create an electrical-circuit maze out of wire, then try to pass a paperclip through the maze without touching the wire.

This lesson focuses on graphene and its electrical properties and applications.

In this activity, learners explore how engineers incorporate biometric technologies into products as well as the challenges of engineers who must weigh privacy, security and other issues when designin
