Week 4 and this past Tuesday was our first test. Class average was an 82 and possibly a little higher once we cleared up some errors with how some of the students read some questions. Once that was complete we began our next unit with atomic structure and the models of the atom. Starting with the ancient Greeks and then progressing up to what we know about the current size of the atom. This week included a couple more videos and we learned that if we enlarged an atom to the size of an football stadium then the nucleus would be the size of a marble placed on the fifty yard line. The rest empty space!

With that we decided to try our hand at being able to picture something without actually being able to see it. Similar to how scientists determined what the atom looked like without being able to see it. So we all took part in: Rutherford's Gold Foil pizza box prediction activity.
Who knew rolling a marble in a pizza box could be so much fun.
Next week we start off Monday with some atomic structure practice using the our technology for our quiz Tuesday.
Then we start NUCLEAR!
