Which materials are conductors? Which materials are insulators? Third graders are testing a wide variety of materials to see which materials allow electricity to pass through them (conductors) and which do not (insulators). They are using evidence from their tests to determine which materials are insulators and those that are conductors.
Here a third grader wanted to test if Mrs. Brinza's earrings were electrical conductors. The evidence that they were??? The light bulb in the circuit lit up!
