HON CHEMISTRY: Wow! Lewis structures, multiple bonds, and now resonance, and now polyatomic ions! That’s a lot you’ve conquered in the last couple of days!
Here’s some good advice – don’t take shortcuts. Learn the proper steps on the easier molecules, and you’ll be able to do the hard ones. And if it’s still all Greek to you, don’t worry! Keep practicing and you’ll get it, I promise!! Don’t forget to count electrons and don’t forget CONS!

PHYSICS: Were you amazed at the effect of change in surface area on the velocity of water, and especially the pressure of water, flowing through a tube? Thaaaaat explains how a calm ride on a lazy river can turn crazy in just a few seconds!
I dug up two old lessons from Bernoulli and posted them below – First, Bernoulli Part 1. We mainly concentrated on qualitative applications of Bernoulli’s Principle with some practical applications. (Ignore all the discussion about the syllabus!!) The second covers more of the conceptual stuff with a beginning look at the problems.
Speaking of syllabus, UPDATE: Pg. 289: 17 – 21 and Bernoulli Worksheet DUE FRIDAY

HON CHEMISTRY – I just love dots! Here’s the lesson from Tuesday on drawing Lewis structures. Make sure you practice, practice, practice! Warning: before you know it, you’ll be seeing dots everywhere!

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.

CHEMISTRY: God bless as you study for the chapter 4 test! I found a couple of old vodcasts from last year that might be helpful – especially if you were absent. First is an overview of the chapter. Below that is the helps session that we did before the test.
Have you checked out the Chapter 4 Stuff to Know Sheet? 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? Neon signs, 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: Wow! Great job on the flame test lab – pretty cool, huh?! It’s one of my favorite labs. Did it help you understand something about how fireworks must work?
Lab reports are due by MONDAY, 8:00 A.M., saved as a PDF to both Google Drive and turnitin.com. It would be a very good idea for you to go back and check your graded labs in Evernote AND double check the lab manuscript form sheet to make sure your lab report is complete and in the correct format! I cannot stress that enough!!
Double check your data table – did you include ALL your observations? Also, what about your conclusion? Be sure an answer the objective, and explain how you used flame tests to identify an unknown. And don’t forget the questions at the end!
Here are some AWESOME interview from the lab!
HON CHEMISTRY: Okay, this no microphone thing is getting a little old, BUT I think I’ve found a couple of old vodcasts that kind of sum of what we’ve been doing the last couple days. They won’t be be exactly like our last couple of classes, but I think they’ll be helpful. First is an overview of Chapter 5 – including the Marsh test results. Below that is an old overview of the Reverse Scavenger Hunt.
Do you plan to practice #50 – 53? Strongly encouraged! Did you understand it when we did it today in class? Help session Friday morning, 7:20ish A.M.

CHEMISTRY: Kind of an odd Wednesday! A mix of homework review and new notes – all super important stuff. I loved watching the way you were applying what you know about electron configurations!! This vodcast from last year is definitely one you want to watch if you’ve been absent and one that would be helpful to look back at as you study for the test! Start watching it at 4:00 minutes.
Need more help/practice? Help session next MONDAY morning, 7:20ish A.M.

PHYSICS: Did you realize that fluids could produce that much force? Make’s you wonder at the awesome way God designed those beautiful under water sea creatures to withstand so much pressure, doesn’t it? This little creature is a lionfish from the waters of Lembeh, Indonesia.
Oh, and here’s the lecture on Pascal’s law and hydraulics and the like.

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!?!
