Learners construct an electricity-generating wind turbine out of a plastic bottle.

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

Learners make a simple battery out of "sandwiches" of aluminum foil, pennies, and a salt water-soaked paper towel.

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, you'll make an electric motor--a simple version of the electric motors found in toys, tools, and appliances everywhere.

In this activity about electricity and magnetism, learners examine what happens when a magnet exerts a force on a current-carrying wire.

In this activity, learners create an electrical circuit and investigate how some dissolved substances conduct electricity.

This activity requires a Pico Cricket (tiny computer). Learners work on designing and building a sound sensor out of household materials, like plastic wrap and cardboard.

This is a series of demonstrations about different electrical and magnetic phenomena.

Make a model city happier with LEDs, circuits, motors, and batteries! Groups can think, discuss, design, and build what would make a community happy. Kids can work as part of a team or on their own.

In this activity related to magnetism and electricity, learners observe as two parallel, current-carrying wires exert forces on each other.

In this activity about electricity, learners produce a spark that they can feel, see, and hear. Learners rub a Styrofoam plate with wool to give it an electric charge.

In this activity related to magnetism and electricity, learners create a magnetic field that's stronger than the Earth's magnetic field.

Learners are challenged to create solutions that conduct electricity and make a buzzer buzz (or an LED light up).

In this activity about electricity and magnetism, learners discover how a doorbell works. A coil of wire with current flowing through it forms an electromagnet that acts similar to a bar magnet.

In this activity about chemistry and electricity, learners form a battery by placing their hands onto plates of different metals.
