CHEMISTRY: Happy Leap Day! 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. Hey, as you are studying for the test (and you are studying, aren’t you?!?), don’t forget the element videos in Vodpod collection below. To review [...]

HON CHEMISTRY: Wow! Who knew you guys had such “electric” personalities! Here’s the lecture on metallic bonding. Aren’t you glad there are no structures to draw! Make sure you can use the electron sea model to explain the properties of metals. Also be able to compare and contrast all three types of bonds. We missed [...]

HON CHEMISTRY: Hey guys, here’s the lecture from Tuesday on ionic bonding. Wow, we missed a whole bunch of you. Hope you get well soon, I don’t like having class without you! Back to ionic bonds – keep in mind that when you write ionic bonding, you’re not trying to arrange a single structure like [...]

CHEMISTRY: Wow! There’s a ton of interesting and important stuff to know about the elements! To make things a bit easier for you, I’ve consolidated the notes on each block into three separate vodcasts. Don’t forget to pay close attention to properties (physical & chemical), occurrence, and uses. As you are studying, make sure you [...]

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 Monday on Bernoulli – Part [...]

HON CHEMISTRY – Who knew we’d be doing geometry in chemistry?!? Here’s the lecture on molecular geometry, with a little practice at the beginning on polyatomic ions and resonance. Molecular geometry is super easy. Make sure you know how to draw Lewis structures, then determine the type of ABE structure and you’ve got it. Easy-peazy! [...]

HON CHEMISTRY: Hey guys, great job with Lewis structures, multiple bonds, resonance, and polyatomic ions today. Wow, that was a lot! 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 [...]

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 from Monday on Pascal’s law [...]

HON CHEMISTRY – I just love dots! Here’s the lecture on drawing Lewis structures. Practice, practice, practice. You can do it! Warning: before you know it, you’ll be seeing dots everywhere! flickr photo by Spotted drum ♥ (on & off)

Chemistry in poetry – who’d of thought of such a thing? Any questions? Don’t forget to print out the Periodic Table of Poetry Mini Project requirements – you can find it posted in the project section under the tab at the top or on Edline. And then, you sign up here by posting a comment [...]
