In this activity, learners will build a simple electromagnet. They will test variables that would make the electromagnet stronger.

This is an activity that demonstrates how batteries work using simple household materials. Learners use a pickle, aluminum foil and a pencil to create an electrical circuit that powers a buzzer.

In this activity (26th on the page), learners construct an easy-to-build device and test motor learning.

In this activity related to Newton's Laws of Motion, learners build a boat powered by a propeller in the air.

In this activity, high voltage is applied across a pickle to emit a yellow glow. This activity should only be conducted by skilled adults and is best suited as a demonstration.

Learners follow directions to construct a water-powered electrical generator using a turbine made from plastic spoons.

In this activity about electricity, learners identify parallel and series circuits. First, learners examine and label diagrams of complete circuits.

In this activity about electricity, learners identify closed and open circuits. First, learners examine and label diagrams of open and closed circuits.

In this activity on page 4 of the PDF, explore the unique molecular structure and conductive nature of graphene. Learners construct a circuit with a battery and LED bulb.

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 design challenge activity, learners invent a device that will make their friends and family ask, "What's buzzing?" Learners design an alarm with an on/off switch that is small enough to hide.

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