Electricity Do you know the following words? Electricity Charge Battery Electron

Station 1: Lemon-powered battery

Station 1: Lemon-powered battery Electrons flow from the zinc in the nail to the copper in the penny Powers the light bulb

Station 2: Charged balloon

Station 2: Charged balloon Atoms are made up of electrons, protons, and neutrons Protons – positively charged Electrons – negatively charged Neutrons – neutral, no charge By rubbing the balloon on a surface like a wool sweater or carpet, the balloon becomes negatively charged. Electrons jump from the sweater to the balloon, and the balloon sticks to the sweater…opposites attract!

Station 3: Build a circuit Using the given materials, create your own circuits. Wires with alligator clips Batteries Light bulbs

Conclusion After completing all of the stations, try to explain these terms that you saw at the beginning of the lesson: Electricity Charge Battery Electron
