Blog Week 23

On Monday, I was absent. On Tuesday, I was absent. On Wednesday, we talked about the lab that was done on Tuesday. I didn't really follow the talk about the lab. I learned that an electron is smaller than an atom and it has a negative charge. Atoms where discovered by John Dalton, while electrons where discovered by JJ Thomson, he did the experiment that proved electrons had a negative charge. In the atom there's a positive charge all around the electrons. It's like plum pudding the electrons are the plums and the positive charge is the pudding. When two neutrals are rubbed together, after that they each get a separate charge, one positive and the other negative. Negative and positive attract, negative and neutral attract, positive and neutral attract. On Tuesday, we did an experiment to find out which materials could conduct electricity. We found out that metals are conductive. This is a list of materials that are conductive: silver fork, silver plate, foil, copper, iron, brass, pop can and license plate. This is a list of materials that are not conductive: card board, glass and water. We also learned that electricity is the flow of electrons. On Friday, we talked about particle diagrams. We talked of how electrons move through each material, but they have to be conductive. I'm still not sure I get all of this information, but I will caught on eventually.
