Chemistry 9-25-12 Chemical & Physical Changes

CHEMISTRY – Happy Homecoming! Here’s the lecture on chemical and physical changes, and also on the laws of conservation of mass and energy. Good job on tracing the energy transformations from one form to another. Make sure you can apply all this on the test (and in life!). 🙂

  1. I had alot of fun doing the lab about the law of conservation of mass. It was really cool seeing the requirements you had to meet to achieve this law.

  2. The lab on the Conservation of Mass was really good not only to understand the material better but it is helping work on using our time wisely and working quickly yet accurately!
