CHEMISTRY: So how do you know if something is a physical or a chemical change? Applications, applications! Make sure you can apply what you learned today. Ditto on the law of conservation of mass.
UPDATE: Vodcast now has sound!
Good job on the Mass without a Balance Lab!! UPDATE- Lab report is due Monday midnight, submitted to Google Drive and Turnitin.com as a PDF.
The thLab: Candle Observation will be a great way to review properties and changes. You’ll write that one on notebook paper and turn it in in class on Monday. Have fun and don’t burn anything down!!
