PHYSICS: You’re doing a great job on the torque problems! Here’s the problems review we did today. Also, click here for a copy of the TORQUE II Worksheet. Hope you have a great weekend!

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!

HON CHEMISTRY: Here are the notes on the elements of the s-block – everything from bananas, to bones, signal flares to street lights. Don’t forget to pay close attention to properties (physical & chemical), occurence, and uses. If you want to see some really interesting videos on some of the more “explosive” elements, check out this link – http://periodicvideos.com/

And guess what I found out today – chalk isn’t really chalk! I mean, just like pencil lead isn’t really lead, blackboard chalk isn’t made of calcium carbonate anymore, it’s made of calcium sulfate (commonly called gypsum) instead. Who knew!

HON CHEMISTRY: Isn’t the periodic table an amazing thing? It will surely 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? This vodcast from last year will go back and explain how you were able to figure it out using the periodic table. Don’t forget, practice, practice!

PHYSICS: Ohhhhhhh, so that’s how that trapeze guy stays up there! Wait – what’s the pole for?? Here’s the lecture from Wednesday on center of gravity. Great opportunity for discussion!

CHEMISTRY: Wow! Great job on the flame test lab – pretty cool, huh?! It’s one of my favorite labs. What was your favorite color. Did it help you understand something about how fireworks must work?

Lab reports are due Monday. What about the conclusion? Answer the objective, and explain how you used flame tests to identify an unknown. And don’t forget the questions at the end!

HON CHEMISTRY: From Tuesday, here’s the brief, brief intro we did on the history of the periodic table – right before you started pretending to be Mendeleev.

We missed you Candice. Happy new baby in your family!

PHYSICS: Welcome back to the first day of a brand new chapter in physics – one of the last we’ll do on mechanics!! Here’s the lecture from Tuesday on torque. Let’s finish up center of gravity tomorrow. So how’s the balance in your life right now?

CHEMISTRY: Fun field trip today! What? There really aren’t tiny people living in boxes above the doors at Wal-mart? Good job coming up with examples of the photoelectric effect. I hadn’t ever thought about those automatic flush toilets!

What did you think about the problems? Again, make sure you not only memorize formulas, but also be careful to learn the symbols and units for each of the quantities you’re going to use, it’s easy to get them confused. Here’s the lecture from Monday – well, not exactly. Someone, and that would be me, forgot to turn on the mic, so here’s a blast from the past that will work.

CHEMISTRY: So tell me again, if we’re supposed to be figuring out electrons, why are we studying waves? Here’s the lecture from Friday on just that. Make sure you know the types of electromagnetic radiation and the uses of most of them (all except for long waves). How’d you like the light problems – so far? We’ll explore waves further Monday – make sure you bring a calculator to class!
