Physics 11-28-17 The Work Energy Theorem & Conservation of Energy

PHYSICS: See?! I wasn’t kidding about the balancing rocks movement!

Great job today on making connections between work and energy! I think you’ll like using the work-energy theorem, it’ll save you some time and a couple of steps. Don’t forget about friction!

Hon Chemistry 11-28-17 Isotopes & Average Atomic Mass

HON CHEMISTRY: Awwww….aren’t they cute! So what do you think the average atomic mass of puppies is?

Here’s our discussion for Tuesday on isotopes and calculating the average atomic mass of isotopes. Isotopes…. not puppies. 🙂

Chemistry 11-28-17 Percent Composition

CHEMISTRY: Great job today… a little bit different lab procedure, huh?!! This lab is answered only on notebook paper – be careful to show correct data and calculations!

BTW – I think you’ll find that percent composition problems are really easy to catch on to. Make sure, though, you can write chemical formulas (I won’t give them to you!) and that you’ve memorized the formulas for acids and those chemical names for common substances so that you’ll have something to find the percent composition of!
