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 robotics activity, learners find ways to express emotions and feelings using only body movements, not facial expressions.

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

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, children and adults work together to explore their relationship with technology and examine ways to make sustainable media consumption choices.

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

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

In this activity, learners light an LED with five cents. Learners use two different metals and some sour, salty water to create a cheap battery.

In this activity, learners use UV light to transfer a pattern onto a plastic board. The pattern is transferred by placing a mask (a transparency sheet with the pattern) on a plastic board.

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

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 explore how infrared technology is used by engineers to create equipment and systems for a variety of industries.
