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.

Make your own simple speaker so you can listen to your favorite radio station. Just wind a coil, attach it to a piece of cardboard or Styrofoam, hold a magnet nearby, and listen.

Testing magnets is always a fun pastime, but here, we're going beyond "will it attract the magnet?" In this activity, learners will investigate which materials allow magnetic fields to pass through or

With a magnet, iron fillings, and a bottle, you can create a cool demonstration about magnetic lines of force: the fillings will arrange themselves within the magnet's magnetic field.

In this activity, learners create a tiny electric, motorized dancer. Learners use the interactions of magnetism and electric current to make a wire spin, while displaying the Lorentz Force in action.

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

In this activity, learners make a 3-D model of magnetic fields by inserting a small, strong magnet into a sphere.

In this activity and demonstration about electricity and magnetism, learners observe how the current generated when one copper coil swings through a magnetic field starts a second coil swinging.

Do you have an extra portable cassette tape player hanging around?
