Friday afternoon we played with electric circuits. Once we had them set up, we used it to test different objects (materials) for conductivity. Plastic straws, spoons, Popsicles sticks, and screws were all put to the test. If the light bulb turned on our objects was announced as a conductor, while no light indicated insulators.
