We have been having some fun exploring electricity, circuits, conductors and insulators. Each student and a partner made their own circuit boards, which when I showed them my example, they were so impressed. And as a result, they really got into making their own. But only after they figured out how to light the light bulb with a battery and paper clip, another challenge that taught patience and perseverance, as well as learning about circuits.
