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.
Speaking of the law of conservation of mass – lab Monday. Come prepared – be sure to read so that you’ll know what you are doing! You’ll only have about 12 minutes for Part 1 then you’ll finish Part 2 in class on Monday!!
Good job on the Mass without a Balance Lab!! Lab report is due Saturday 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. Have fun and don’t burn anything down!!
