Coulomb

Coulomb’s law talks about the conditions an electron faces as it leaves an atom, and it has three main points. 1. Coulomb’s law states that protons have a positive charge and electrons have a negative charge. 306 more words

Amp it up, Andre!

Typical day in a classroom in Southern Adelaide a few years ago, when I was still teaching Science:
