HON CHEMISTRY: Hey guys, welcome to chemical bonds! Great job on using electronegativity to determine bond type. Make sure you add that scale and also the diatomic molecules to your “things I have to memorize for the test” list.
Pretty cool the way orbital notation allows you to see how electrons are shared, huh?!? Let’s play with dots tomorrow!
🙂

PHYSICS: So when you were floating in the pool this summer, did you enjoy your fellowship with buoyant forces? 🙂 Here’s the lecture from Thursday – Archimedes’ Principle.
Great topic for investigation! Speaking of which – what did you find? When the kid jumped out of the boat, did the water level rise, fall, or stay the same? Hmmmm…..
UPDATE: Now with audio…

CHEMISTRY: God bless as you study for the chapter 4 test! Here is the overview that we did today of the chapter. SUPER IMPORTANT that you watch this vodcast as you study!!
Have you checked out the Chapter 4 Stuff to Know Sheet from Edline? Make sure you memorize the things you need to memorize so that you can apply them on the test. And practice, practice, practice, the problems and electron configurations.
What about applications for discussion? Photoelectric effect, spectroscopy, etc.? Another great idea for studying is to watch the videos that we watched in class – super helpful as you study for the test!! Check them out on the the earlier lesson web posts. Here are some of them:
Spectrum of the Stars (overivew of the results of the spectroscopy lab you did, shows the connection between our lab on spectroscopy and how we can identify elements), Emission Spectrum of Hydrogen (how we use it to know about the energy levels in an atom), Quantum Mechanics (about the roles of Bohr, Schrodinger, Heisenberg), and also Animated Quantum Mechanics.
God bless you! I’m praying for you!!

CHEMISTRY: Here’s the help session from Thursday morning – practice on some of the wave problems that we did at the beginning of the chapter.
CHEMISTRY: Here’s the review of a little of all of the electron configurations from today’s class. ALSO – a look at one of the homework questions that only 6th period asked me about – good job 6th period. Might be worth a look!!
Need more help/practice? Help session tomorrow morning, Thursday, 7:20ish A.M.

PHYSICS: Wait! There’s a fourth law? Yep – Newton’s law of universal gravitation! So when you jump off of something, the Earth moves, huh?
You’ve learned little g, now you know big G! Good job setting up the problems, also make sure you can apply the concepts.
Ready to escape? 🙂

HON CHEMISTRY: God bless you as you study for your test on chapter 5! Here’s our overview of the test from today, as well as a look at some of the homework problems.
Speaking of studying for the test, did you find the Chapter 5 Stuff to Know Sheet on Edline? A couple of other items for discussion – besides the ones on the sheet, that is, why is grass greener after a lightening storm? And don’t forget about arsenic poisoning – the symptoms, the test, and how the test works.
If you need any extra practice – helps session tomorrow morning at 7:20ish A.M. Good luck studying. I’ll be praying for you!!

CHEMISTRY – You too can conquer electron configuration! If you caught on to noble gas notation today, that’s great! But if you are having a bit of difficulty with noble gas notation, no problem! Watch this vodcast again and it will make even more sense the second time! It would also be great review for the test!
Hey, how’d you like reading electron configuration from the periodic table? Super cool, huh? And isn’t God awesome!?!

PHYSICS – Wow! Could you do this? Here’s the lecture on rotational inertia, angular velocity, and angular momentum – rotational dynamics! By the way – I wonder how all this applies to other rotating things…like maybe the Earth? Hmmmmm……
