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 examine fingerprints. Learners leave a hidden print on a surface and then make their own print detecting powder from graphite (found in pencils).

In this activity about electricity, learners explore how static electricity can make electric "fleas" jump up and down. Learners use a piece of wool cloth or fur to charge a sheet of acrylic plastic.

In this activity, learners investigate the behavior of magnets. Learners create a "wonder wand" with a magnet so they can move a skater around.

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

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.

In this activity/demo about piezoelectricity, learners discover how some crystals produce electricity when squeezed.

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 related to magnetism and electricity, learners discover that a magnet falls more slowly through a metallic tube than it does through a nonmetallic tube.

Construct a simple battery that's able to power a small light or motor out of foil, salt water, and charcoal. A helpful video, produced by the Exploratorium, guides you along on this activity.

In this activity, learners will investigate static electricity as they create waterless snow globes.

Make your own speaker with a magnet, wire, and paper cup! If you have a radio with a headphone plug and an old pair of headphones, this is a great tinkering activity.

In this activity, Frankenstein's lab is running out of electricity! Learners use fruit to help Igor find a temporary source of energy to turn on a light.

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.

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

Did you know that some breakfast cereals are fortified with ferric phosphate, while others contain tiny pieces of reduced iron?

In this activity about magnetism (page 17 of the pdf), learners experiment with magnets, exploring the concept of diamagnetic materials by seeing how a grape reacts to a magnetic field.

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.
