Chemistry 3-29-17 Polyatomic Ion HW & Intro to the cLAB

Posted on by

CHEMISTRY: From Wednesday, here’s a short review of some of the homework – polyatomic ions, and especially acetate, super important!! How about molecular geometry? Anyone need to review that? Help session?

Also, at the end of this vodcast we began discussing the cLAB: 3D Molecules. Great idea to review if you were absent!! We’ll work on the cLab again tomorrow in class. One update to the project: include a title “slide” with your name, period, date and title of the project – just like a lab.

Hon Chemistry 3-29-17 Synthesis Reactions & a Head Start on Decomposition

HON CHEMISTRY: Oooohhhh! So that’s where the pretty light comes from! Great job on synthesis reactions! Since we had no audio and I’m posting a lesson from last year, you also get a beginning on decomposition reactions! Now go forth and practice what you learned! (The balancing equations part, not the playing with magnesium part!) 🙂

Physics 3-29-17 Waves

Posted on by

PHYSICS: Hey guys! Here’s our discussion on the properties of waves. Remember anything from your earlier 8th grade physical science days? 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!
