Nov 13-14 Starting Chemistry

Today in class we had a whirlwind refresher on sixth grade chemistry. We touched on the parts of an atom (Protons, Neutrons and Electrons). We talked about the difference between atoms (no charge) and ions (have charges).

We then reviewed the periodic table, talked about how protons made the atom--any atom with one proton was a hydrogen atom (number 1 on the periodic table), any with 2 protons was Helium (number two on the table). We pointed out the noble gases and the halogens, or salt formers.

All this information can be found in the introduction to matter book (see my website for the online version of the book).

Finally, we discussed our elements project--We will be creating fact sheets, 3-D models and a commercial about an element. We saw sample commercials from previous classes.

This project will have three parts, and three due dates. Please see the Elements project page on my website for the specific due dates.
