Physics 11-29-11 Chapter 5 Review Worksheet Problems

PHYSICS – Hey guys, it was good to get back to exercising the old gray matter today! Here are some of the problems from the first chapter 5 review worksheet: 3, 4, 5, 2, and 10. Watch out for 2 and 10! You did a great job on them with me in class, but make double sure you can work them also by yourself. That’s homework tonight, re-work by yourself the ones you didn’t get before. And then do it again til you make sure you have it! πŸ™‚

I’ve never seen Old Faithful in person, have you? So we calculated the velocity of the water coming from the bottom – reckon how much power that would be? Power? Let’s talk about that tomorrow!

Chemistry 11-29-11 Dalton’s Atomic Theory vs. Modern Atomic Theory

CHEMISTRY: Wow! Pennies turned to gold? Tell me again – how you could you prove that it was or wasn’t? Hey – what a lot of theory today! So the smallest thing that can be that thing is an atom. How do we know that? Well, we have to start at the beginning, and that’s Dalton’s Atomic Theory. Great job today comparing it with the Modern Atomic Theory. Keep those examples in mind when you’re studying for the test – especially when it comes to explaining those laws.

Did you hear about the make-up lab change? It will be this Thursday at 7:15 A.M. – last one of the year!

By the way – when you listen to the vodcast, that awful clicking noise you hear just might have to do with my necklace sliding back and forth across the mic. Sorry about that! πŸ™‚
