Third graders are closing the year building and testing circuits. They're also using different materials in their circuits to see which ones allow electricity to pass through them. Materials that allow electricity to pass through them are called conductors. Students began seeing that materials that conduct electricity are typically made of metal, and materials that did not allow electricity to pass through them are non-metals. These materials that don't allow electricity to pass through them are called insulators! |
