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

In this design challenge activity, learners invent a pinball-like game where a kick stick hits a ping pong ball into a target that buzzes.

In this activity, learners take apart a used zinc-carbon dry cell battery.

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.

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.

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

In this activity, learners explore the parts of a circuit by modeling, as a group, a “human” circuit.

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 an everyday situation, where either of two or more buttons can ring a buzzer.

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.

This activity requires a Pico Cricket (tiny computer).

In this activity, learners build a switch to turn electrical circuits on and off.

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 construct wands that play different notes depending on information from light sensors programmed via a PICO Cricket.

In this activity, learners discover that training a robot can be hard work! Learners investigate how robots complete a task by following a list of sequential instructions.

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

Build a musical ice theremin by programming a micro controller, like a Pico Cricket to respond to resistance generated by the ice melting, or the ice being touched.

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

In this optics activity, learners use glass and water to demonstrate total internal reflection (TIR).

In this activity, learners explore electronics and motion by making a Scribbling Machine, a motorized contraption that moves in unusual ways and leaves a mark to trace its path.
