Model Work...

In the 11th and 12th grade Chemistry class we've been learning about the history of the modern model of the atom: the men, the discoveries, and the changes. These changes in the model were huge steps in understanding the structure and function of the atoms of each element. During class we watched two videos that demonstrated how a cathode ray tube works (used by J.J. Thomson to discover the electron) and the Gold Foil experiment (used by Rutherford to discover the nucleus of the atom).

Basically we're stepping into the world of the Periodic Table and how atoms combine to form substances all around us.

So in learning about the structure of the atom we designed a few ourselves. In fact, we used the basic idea of Bohr's model (even though his was only good to represent the Hydrogen atom) and with paper plates and Trix cereal you have these...
I'd say that's some pretty model work.

Parents, stop in sometime and take a peek at what we're learning. Or you can see it all on display, Friday, December 12th, right after the Elementary Christmas program.
