CHEMISTRY: I missed you guys today! Sorry about the scratchy vodcast. How’s it going working with completing and balancing chemical reactions? Are you getting better at remembering how to write formulas? And how are you doing on memorizing the equations? And today you got a head start on the activity series. Good job! Here’s a [...]

CHEMISTRY: Wow! So that’s where the pretty light comes from! Great job on synthesis and decomposition reactions. We’ll finish decomposition tomorrow. Now go forth and practice what you learned! (The balancing equations part, not the playing with magnesium part!) UPDATE: Sorry the last vodcast had bad audio. Try this one and see if it works!

HON CHEMISTRY: Remember all that stuff you learned about stoichiometry? Seems like forever, doesn’t it. Let’s have a help session tomorrow, Thursday, morning around 7:15 or so. Oh, and in case you missed it, the test has been moved to Friday!

HON CHEMISTRY: Wow! Great lab results today! So here’s an old lecture on percent yield. It’s the last of the applications of stoichiometry problems. Lots easier that limiting reactants, I think. You realize what we’ve done… we’ve finished the chapter!!

PHYSICS: So why do instruments that are playing the same note sound so different? Here’s the lecture from Monday on harmonics & beats. Have you ever seen sound? Here’s an applet you might be interested in checking out: The vOICe Java Applet. Click on the name, or it’s at http://www.seeingwithsound.com/javoice.htm You might have to update [...]

CHEMISTRY: Need some help balancing equations? Here’s day two of “How to write a balanced chemical equation.” And don’t forget – first, check and make sure you have the formulas written correctly. Then, if you can’t get the equation balanced, go back and check the formulas!! You can do this!

Do you need the easy button?? How’s it going? You are going to survive, I believe in you!! I’d wish you good luck, but I know it really doesn’t have a thing to do with luck. You’ve been working really, really hard, and I know it’s going to pay off. I’m praying for you! I’ll [...]

CHEMISTRY: Okay, maybe balancing equations isn’t exactly like this, but….. Here are the introductory notes on balancing equations. Plus – a couple of examples for practice. And, did I mention practice, practice, practice? flickr photo by Pink Sherbet Photography

CHEMISTRY: Hey guys, I’m going to have to make a change in our schedule. We are not going to do the Paper Chromatography lab tomorrow. We won’t do that lab until Thursday, so it doesn’t have to be written up until Thursday. Sorry about the late notice! ________________________________________ flickr photo by ediamond

How’s it going with the Lost in the Dasht-e Lut Project? Some of you have had some good questions about the project and especially about formatting and documentation, etc. Here are a few things to remember: 1. Your printer and the printer at your parents’ job will die/ run out of ink/ jam/ run out [...]
