Chemistry 9-24-13 Chemical Changes & Energy

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!!

Physics 9-24-13 Angular Projectile Problems

PHYSICS – Great job today working through the monkey-hunter problem! So what happened with the last one that we worked? Was the book wrong or were we wrong? Why? Watch our discussion again and see what you can come up with. Bring me an answer tomorrow!

Don’t give up on them tonight! They are tough, but you can do it!
