In this activity, learners build a game that tests their steadiness. Learners construct the game board by setting up an electrical circuit and a wand.

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 an electric two-paddle boat using paint paddles, plastic knives, and empty water bottles.

In this activity, learners explore motion, energy, and electricity by constructing bottle cars that run on motors.

Learners build a simple electromagnet, then use this electromagnet to transform a yogurt container into a working speaker. They can connect their speaker to a radio and listen as it transmits sound.

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 about electricity, learners imagine that they are out in the wilderness and it is getting dark. Their task is to use the materials supplied to build a simple flashlight.

In this activity, learners string a line across the room and build cable cars that can move from on end to the other.

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.

In this activity about electricity, learners build and test a paper clip switch to turn on a light bulb.

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

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

In this activity, learners explore how an electromagnet works by making a simple one. Using this knowledge, learners design a diagram to make a working speaker using household materials.

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.

In this activity, learners explore conservation of energy by experimenting with a solar cell light device.

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

Make your own "Dance Dance Revolution" dance pad! In this design challenge activity, learners work in teams to build a dance pad that lets you use your feet to sound a buzzer or flash a light.

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 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 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
