HON CHEMISTRY: I’m sorry, guys! I just remembered I have a commitment in the morning, so the help session will have to be Monday morning. Sorry about that! It’s what happens when you play with chemicals – memory goes! 🙂

Chemistry 2-21-13 Atomic Radii & Ionization Energy
CHEMISTRY: Here’s the lecture on the first periodic trends – atomic radii and ionization energy. You made some great connections today! Let’s finish second ionization energy tomorrow and other periodic trends tomorrow.
Homework is for tonight is Wednesday’s homework, except the lab pre write-up is not due til Monday.
Hey, as you are studying for the test (and you are studying, aren’t you?!?), don’t forget the element videos at periodicvideos.com. Wait – did I say test?!?
Physics 2-21-13 Bernoulli – Part 1
PHYSICS: So were you surprised about 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! Here’s the lecture from Thursday on Bernoulli – Part 1.
Today we concentrated on quantitative applications of Bernoulli’s Principle and a few practical applications. Tomorrow we’ll take the practical applications to an even higher level (pun intended!). That’s the part I like best. 🙂
Homework – thLAB: Hydrodynamics
Hon Chemistry 2-21-13 Dipoles & Intermolecular Forces
HON CHEMISTRY: Well, here it is, the very last lecture from chapter 6 – intermolecular forces. (Don’t forget they’re also called van der Waals forces!) Tons of application, from bugs walking on water to little fishes breathing dissolved oxygen.
Now to seriously start studying for the test! Have you practiced Lewis structures and drawing ionic bonding? Great idea!! Also, don’t forget the interactive review quizes in the online textbook and also www.sciencegeek.net. The Unit 3 section would be a great place to practice and check to see if you’ve learned what you think you’ve learned. I’ll be praying for you! You can do it!
