I have decided that I am going to give a unit “Flash lesson” to go along with each unit that I teach in class. These are great helpers to really help understand the points that I made in class, or, to give you a second change at understanding the unit because you were too busy texting your bf/gf under the desk and heard exactly 3.7% of what I had to say (and that is probably a high estimate). Unfortunately these lessons do take a while to make, but as they are done, I will upload them for your audio and video pleasure.
Here is the link to the first 2 Flash Lessons. First lesson is Wavelengths, Frequencies, and Spectrums. The Second lesson is a little bit less demanding, and talks about Physical and Chemical properties & The Periodic Table.

PLEASE GIVE THE LESSONS TIME TO LOAD AFTER YOU CLICK ON THE LINK, SOMETIMES IT TAKES UP TO 2 MINUTES TO LOAD FULLY BECAUSE THEY ARE LARGE FILES!!!
