In this activity, learners actually feel the difference in energy required to light two different types of light bulbs: incandescent light and LEDs.

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 use their strength to light a light bulb. A chain made from paper clips is placed in series with a battery and flashlight bulb.

In this activity, learners create night lights using a plastic cup, programmable PICO Cricket, tri-color LED, and sensor.

In this activity, learners discover what happens when they crush wintergreen-flavored candies in a very dark room.

A magic lantern is a light that projects an image onto a screen.

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.

Learners test solutions of water, sugar, salt, and hydrochloric acid for electrical conductivity. They immerse leads from a lighting device (a battery pack connected to an LED) into each solution.

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

In this activity, learners compare and contrast different forms of luminescence by observing how chemiluminescence, phosphorescence, and fluorescence produce or emit light.

Put on a pair of gloves and be the conductor of your invisible orchestra!

Use a Pico Cricket (micro-controller) to animate your art! You can program a Pico Cricket to make your art spin, light up, or make music.

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 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 investigate the properties of graphene and graphite.

In this activity, learners create a marble maze that contains sensors. As a metal marble triggers the sensors, the Pico Cricket turns on lights or spins motors.

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

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.

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.

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.
