PHYSICS: So why do instruments that are playing the same note sound so different? Here’s a slightly expanded version of the lecture from Thursday on harmonics & beats. And how did you like “seeing” sound. Here’s the link to The vOICe Java Applet that I showed you in class today. Click on the name, or it’s at http://www.seeingwithsound.com/javoice.htm
I’ve seen it a hundred times, but it never gets old! I thought the physics class might could use a little inspiration - so this video’s dedicated to them. How’s your Rube Goldberg Project working out? The project is due May 2 (that’s next Monday!) If you need a little more inspiration, check the VodPod below, or check out the videos on You Tube. And just before you finish, don’t forget to review the project guidelines and the project grade sheet to make sure you’ve covered everything. Good luck! I can’t wait to see them!!
CHEMISTRY: Okay, maybe balancing equations isn’t exactly like this, but….. Here are the rest of the notes on balancing equations. Plus – a couple of examples for practice. Have a great weekend! And, did I mention practice, practice, practice?
Wow! You guys are the GREATEST!! Thanks to you, ExploreZone was a HUGE success! The elementary kids loved it and the high school did too! Everywhere I went, I saw faces with smiles and surprise and awe. You worked so hard, and it paid off. A special thanks to all of you who stayed late Monday setting up and Tuesday cleaning up! I couldn’t have made it without you!! Check out the pictures on flickr - more at the left and on the bottom right of this page or here . You can click on them to see the whole set.
Here are some of my favorite quotes:
“Wow, how’d you do that?”
“Where can you buy that?”
“Can you eat it?”
“Hit him in the knee!” (elementary kids are brutal!)
And my all time favorite – “Ooh gross! Do it again!”
HON CHEMISTRY: Well, here it is, the last of the lectures from chapter 8. A couple of things – make sure you’ve memorized the activity series, but just as importantly, make sure you know how to use it! Those guidelines I gave you in class should really help. Good luck as you study for the test on Thursday! I’ll be praying for you!!
HON CHEMISTRY: Hmmmm….somehow we had a glitch in the sound today, so I’m having to be creative on giving you the lecture on single replacement reactions. Moving right along….here’s a lecture from last year on the rest of the types of chemical reactions – single replacement, double replacement, and combustion. You’ll need to memorize all 17 of them (by tomorrow!), but don’t just memorize them. Make sure you can apply them as well. When you start to work any equation, first determine what type of reaction it is, then figure out what rule applies and follow it to determine the products. I believe in you! You can do it!!
