Electricity learning #1

There were three stations in the class activity. One of them we used a balloon to pick up peaces of paper using static electricity. It was just like picking something up with a magnet, but the balloon lost its charge over time. The next we had two strands of tape and we hung them next to each other, when we did they pushed each other away, because they had like charges. We did not have to do anything to the tape it just worked. The last station we were suppose to do something with tape which I nor my team understood. I know from my experience with the other stations that the tape was going to pull on each other or repel each other.

Since i learned that electricity is made up of electrons i began to wander how a electric engine works. At first i thought that maybe the engine absorbed the electrons some how and that's what made it go. But it didn't seem like a sufficient answer. So I thought about it, and i came to the conclusion that the electrons gathered on the metal coils inside the engine and pushed off of each other which spins the engine.
