Van De Graff

                          Van De Graff 

Today in class we played with a generator, what I saw was that it caused electricity. When we tested out with a ball the ball kept touching the generator and moving away from the generator. Then we tested it out with aluminum plates, we made the aluminum plates just sit at the top at the generator and once we plugged the generator back in the aluminum plates went flying everywhere. We also tested out the a glow stick that wasn't glowing and with the generator the glow stick was glowing again.

The science that was behind all this "magic" was that the ball was attracting and repelling to the generator. The type of electricity is actually called static electricity. The generator gave electrons to the aluminum plates, the aluminum plates had enough electrons which then the aluminium plates repelled from the generator and that's what causes the aluminum plated to go flying. The generator gave enough electrons to the glow stick because the glow stick was a conductor which it made the electrons to flow easily though the glow stick which made it glow. 

What I would like to see be tested on the generator is a coin (a type of copper) because probably the coin will repel from the generator then attract from it just like what the ball did.
