5. Station 2: Charged balloon

6. 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!

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

8. Conclusion
