Chemistry 3-23-12 Covalent Bonds & Intro to Lewis Structures

CHEMISTRY: Well, since we began the weeks with learning how we can’t always trust what we think our eyes see, and then we ended the week with dots, I thought this would be the perfect picture to go with today’s vodcast. Can you count the black dots? How many? Are you sure?

Good luck practicing Lewis Structures this weekend! You’ll be seeing dots all over the place before you know it!! 🙂

Physics 3-23-12 Waves

PHYSICS: Happy Friday! 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).

And hey, did you figure out that problem from the end of class yet? It’s not that difficult, really. 🙂 Bring me the answer on Monday, and let’s take waves a step further then. Have a great weekend!
