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!). 🙂

Physics 9-25-12 Horizontal Projectile Motion

PHYSICS – Great job today, and applying stuff from the last chapter no less! Here’s the lecture from Tuesday on horizontal projectile motion. Just go slow and easy and you’ll master it in no time flat. Tomorrow let’s try projectile motion at an angle. Watch out for squirrels throwing nuts!

Hon Chemistry 9-25-12 Mixture Separation Lab

HON CHEMISTRY: Pretty intense couple of days, huh? You know, I’m really proud of you! It’s one thing to be able to follow a set of directions, but it’s a whole other thing to be able to come up with the directions on your own! That’s a difficult thing to learn how to do, and you are doing a great job developing that skill.

Any questions about writing up the lab report for tomorrow? Use the Lab Report manuscript form you can find here or on Edline. Remember, some of you definitely need to elaborate on your procedure! And then, after you write your own conclusion, don’t forget all of the questions on the lab sheets. The answers, in complete sentences, go after your own conclusion.
