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.
PHYSICS: Here’s one last review of the conservation of energy and work-energy theorem problems. We did the Tarzan problem and a few sliding up and down inclines (the problems, I mean, not us!) – #40, 41, 46, 48, I think. Good job on them! We’ll do power on Monday. Have a great weekend!
CHEMISTRY: Great job with Part 1 of the Spectroscopy Lab using the diffraction grating! Here’s the mini-lecture on the intro to the hydrogen emission spectrum and the lab from Thursday. How are your drawings coming? If you have a question about the lab presentation, this is the vodcast with the instructions. Also, if you’re not going to be in class tomorrow, you can come by any time to make it up. The whole packet, including drawings, is due Tuesday.
HON CHEMISTRY: Wow! Great job on the flame test lab – pretty cool, huh?! It’s one of my favorite labs. Lab reports are due Monday. What about the conclusion? Answer the objective, and explain how you used flame tests to identify an unknown. BTW – how did the spectroscope work out? Address that in your conclusion as well. And don’t forget the questions at the end!
