Circuits

In today's Science class we learned about circuits with electricity. My Science teacher showed us this application called Circuit Construction Kit, now I have to write a report about what I've learned from this application.

So one of the easiest circuits to make is pretty much this:

A single cell with a light bulb and a switch

One that looks like this is called a serie circuit.

This is a complete circuit, there are no gaps neither damaged area's. That's also how a switch works, it makes a gap in the circuit when you want it off so it doesn't work anymore, when you switch it back on it repairs the gap and the circuit start working again.

The whole point of a single cell is that the electrons move from a high concentration (the + side of a single cell) to a low concentration (the - side of a single cell), so if there is no - side to go to, why would the electrons move? 

A different kind of circuit looks like this:

This is called a parallel circuit. Where at one point the wire split up and later come back together. Notice the Amps change throughout the wire.

There was also a bag located on the top right corner. I put each item in a circuit of just a single cell. The once that worked where:

A paperclip, but it bursted into fired immediately

A pencil (with lead inside), it was very very slow though

And a coin, but was surprising to me is that the electrons lost some of their voltage the longer the wire is. 

Some of the object that can't convert electricity are:

A rubber

A dog

A dollar bill

A hand

What do the object that do convert electricity and don't have in common. Well if you notice that all the object that it does work on (paper clip, coin, pencil) are all made out of metal. Metal is a good electricity conductor, and the other (rubber, dog, dollar bill, hand) are all non-metal and because of that poor electricity conductors.
