Chemistry Unit 4: Density and Unit 5: The Periodic Table

Density was a fun and simple unit. The chemistry lessons from the ACS website (Chapter 3)were easy to follow. The labs did a great job explaining how and why different molecules had different densities. As an added bonus – try dropping an Alka-Seltzer tablet into the layered liquids.

Next, we explored the periodic table. First, my son watch the Brain Pop videos Periodic Table of Elements and Isotopes. Both had vocabulary and follow up worksheets. Next, he watched the Crash Course Chemistry videos #4 and #5 The Periodic Table and The Electron. I worried that the orbital shells of the electrons would be above him, but he grasped it with no problem. We finished with the labs in the ACS lessons (Chapter 4). It’s looking more and more like he has a natural aptitude for chemistry.
