In L2 Physics we started unit on circuits recently and students were wondering what goes on inside of a battery to create energy. We went back to chemistry and reviewed reactions that involve the transfer of electrons. Then we built “batteries” out of lemons, a penny and a nail. In order to power an LED bulb, students needed to string together 3 lemon batteries to get enough current to light up a bulb. Alas, we could not charge our iPhone (maybe that needed an apple instead of lemons ? 😊 Comments are closed.
