CHEMISTRY – Happy Homecoming! So how do you know if something is a chemical and change? Applications, applications! Make sure you can apply what you learned today. Ditto 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!). Did I mention that already?
Speaking of the law of conservation of mass – lab tomorrow! Come prepared!!
