CHEMISTRY: Don’t you just love dots??
Great start on Lewis Structures! Practice, practice, practice. Warning: before you know it, you’ll be seeing dots everywhere!

HON CHEMISTRY: NOW WITH SOUND! 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.

HON CHEMISTRY – So why is molecular geometry important? I mean why is knowing the correct shape of molecules? Here’s the beginning of the answer! Great job on drawing dipoles. We’ll continue our discussion on intermolecular forces tomorrow.
PHYSICS: Hey guys! Here’s the lecture on the properties of waves. Problems are pretty simple for you, I think. Do you remember the main formula from chemistry? Speed = wavelength x frequency (c = λf).
Easy peasy – and don’t forget the applications!

CHEMISTRY: Welcome back to chemistry! Ready to begin another chapter? Here’s the first lesson from chapter 6, the introduction to chemical bonds. Don’t you wish all the problems would be this hard?!

PHYSICS: Springs and pendulums, back and forth… back and forth. Here’s the lecture on simple harmonic motion.
Wonder how it could be used to solve a design challenge?
