I hope you’re having a wonderful Thanksgiving! Do you know what I’m very thankful for? You! Thanks for the hard work you’ve put into chemistry and physics. Keep it up and don’t give up. Stay strong and trust in the truth that will never fail, that will endure forever! “Enter into His gates with thanksgiving and into His courts with praise. Be thankful unto Him and bless His name, for the Lord is good, His mercy is everlasting, and His truth endures to all generations.”
Physics 11-24-09 Chapter 5 Review Problems
PHYSICS: Great job explaining the problems today! So how does the student like being the teacher? Here’s the review YOU gave on the last chapter 5 review worksheet. The sound is really low at the beginning, until Josh begins his explanation.
Chemistry 11-24-09 Electron Configuration Notation
CHEMISTRY: Just when you were getting the hang of drawing arrows, I go and change it! But don’t you think writing electron configuration notation is a whole lot shorter than doing orbital notation? Don’t get me wrong, knowing how to do orbital is great for seeing how the electrons are paired, but this way is waaaay shorter! Here’s the lecture from Tuesday. Don’t forget that you also need to know how to read (only read) noble gas notation and that you need to be able to recognize and explain (not draw) deviant behavior in electron configurations. See you Monday! Happy Thanksgiving!!
Physics 11-20-09 TEST CHANGE!!
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 11-20-09 Orbital Notation
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 11-19-09 Periods & Block of the Periodic Table
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 11-19-09 Quantum Numbers
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 11-18-09 Simple Machines
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 11-18-09 Quantum Model of the Atom
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 11-18-09 History of the Periodic Table
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.
