i was thinking in doing a project on electricity. First we can test positive and negative charges like the guy at the museum of science did. We can test and explain the role of conductors, insulators, semiconducters and superconductors. We can eplain what electrical potential energy is, and what voltage, current and resistance are. then, explain and test OHM’s law voltage= current x resistance. We can built circuits ussing a battery, a light bulb and wires and explain the difference between series and parallel circuits
