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.

This activity was designed for blind learners, but all types of learners can use it to build and examine a basic electrical circuit.

In this activity, learners explore the relationship between electric charges and magnetic fields.

Trick your family and friends with this creepy crawler that moves up and down. In this activity, learners construct a circuit and motor device that will move a homemade spider in a spooky way.

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

Before there were clocks, people used shadows to tell time. In this outdoor activity, learners will discover how to tell time using only a compass, a pencil, a handy printout, and a sunny day.

In this activity, learners build a simple qualitative conductivity tester with a battery, bulb and foil.

In this activity on page 10 of the PDF, learners detect the amount of energy that can flow through a sodium chloride electrolyte solution with a light sensor.

In this design challenge activity, learners design and build a circuit: an "electric highway" that connects a battery and buzzer at least three feet apart using four types of materials.

Learners make a circuit board that has questions and answers. When the correct answer is chosen for a question, a circuit is completed and a light illuminates.

In this activity, learners build a tiny but powerful flashlight out of simple materials. Use this activity to introduce learners to electrical circuits and conductivity.

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 will create a speaker using a paper cup, magnet, and enameled wire. Also included in this activity is a Mr.

Learners observe an electrochemical cell constructed from a small jar containing zinc and copper strips immersed in separate solutions. The strips are connected to a motor that turns a small fan.

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.

In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.

In this activity, young learners investigate magnets. Learners discover that some magnets are stronger than others and that magnets have north and south poles.

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.

In this physics activity (page 4 of the PDF), learners will explore how similar magnetic poles repel one another. They will rely on linear induction to race magnets around a simple course.
