PHYSICS: Well, the more I thought about it, the more realized it just wouldn’t be a good idea to have the test either Monday or Tuesday. I hate to move it to after Thanksgiving, but I think it would be best. We’ll finish correcting the chapter 4 problems and finish the lab on Monday, practice all problem solving on Tuesday, review the Monday after Thanksgiving, and take the test on that Tuesday – December 1. Let me know if you have questions or concerns about this.
Here’s the very brief vodcast from Friday – just a tiny bit of review. I think I went over the answers on the pg. 190-191 review problems, and we also started brainstorming on how to work #17 on pg. 191. See if you can work it now yourself. Have a great weekend!!

CHEMISTRY: Great work today! Are you starting to see arrows everywhere? Be sure and practice. Things to know: how many types for each orbital and the Aufbau chart! Homework for Friday night is Thursday night’s homework. Practice, practice, practice!

HON CHEMISTRY: Great job today! Isn’t the periodic table an amazing thing? It will prove to be a very valuable tool for you! Are you starting to get the hang of using electron configuration to determine the ID of an element, and vice versa? And what about Noble gas notation? It’ll be waaaaaay easier now! Practice, practice!

CHEMISTRY: How’re you doing? Confused yet? Don’t worry – today you learned all the background information about quantum numbers, tomorrow we’ll put it all together and it will begin to make sense. If you didn’t hear the lecture today, this is for sure one that you want to watch! By the way, we’re officially one day behind, so tonight’s homework is to complete Wednesday’s homework (and SItN).

PHYSICS: Hey guys, here’s the lecture from Wednesday on simple machines. We’ll add this little bit of chapter 7 to the chapter 5 test. I don’t think you’ll have any trouble with efficiency and mechanical advantage problems. Lab tomorrow!

CHEMISTRY: So which are they? Are electrons particles or waves? Here’s the lecture from Wednesday. If you’re still having questions, not only watch this vodcast, but also you might watch the video clips we saw in class today. They’re in the Vodpod below – The Emission Spectrum of Hydrogen and Animated Quantum Mechanics. By the way – did you read the cartoon?

HON CHEMISTRY: From Wednesday, here’s the second part of the intro to the history of the periodic table. Noble gases, lanthanides, and actinides, etc.

HON CHEMISTRY: Great start to a new chapter! Do you have a whole new respect for Dmitri Mendeleev? Here’s the brief intro lecture from Tuesday. Let’s talk more about it tomorrow.

CHEMISTRY: Here’s the lecture from Tuesday on the Quantum Model of the Atom. A couple of video clips we watched in class are in the VodPod collection below (you may have to open the entire collection): “The Electromagnetic Spectrum” and “Animated Quantum Mechanics.” They’d be great for review.

PHYSICS: Great job on the horsepower lab. Lotta noise – I’m thinking some of you took out some of your physics phrustrations on the stairs! Post your own horsepower numbers here. Did you notice that not all of the stairs are the same height? BTW: 1 Hp = 746 W and 1 kg = 2.2 lb. Lab reports are due Thursday.
