Hon Chemistry 11-30-12 The Electromagnetic Spectrum & Wave Properties of Light

HON CHEMISTRY: Isn’t this a super cool picture of light? So tell me again, if we’re supposed to be figuring out electrons, why are we studying waves? Here’s the lecture from Friday that very thing. UPDATE: The vodcast below is the lecture from Friday – I finally remembered to upload it.

I’m thinking you’ve probably memorized the electromagnetic spectrum after that inspirational song; however, also sure you also know the uses of the different types (all except for long waves). Just in case you’d like to hear it again: Electromagnetic Spectrum Song

This other video clip on The Electromagnetic Spectrum also gives you a really unique look at the electromagnetic spectrum and begins to connect the lab from today and yesterday to what we are going to learning about in this chapter. By the way, just for the record, I love outside labs!

How’d you like the light problems so far? We’ll explore waves further Monday – make sure you bring a calculator to class!

Chemistry 11-30-12 Structure of the Atom, Pt. 2

CHEMISTRY – So do you have a better “feel” for how scientists like Thompson and Rutherford discovered the parts of something you can’t even see? Isn’t God awesome to give us minds to understand the world around us – even the parts we can’t see!

UPDATE: Here are the questions from the Sock & Can Model of the Atom Lab if you need them: Sock & Can Model of the Atom

Here’s the lecture from Friday on how scientists discovered protons and neutrons. Make sure you know the name of the scientists, the name of their experiments, be able to draw a diagram of their experiment, and describe how they interpreted the experimental results that led to their discoveries. By the way, here is the link the to video clip about the discovery of the nucleus that I was telling you about in class: The Discovery of the Nucleus. Along with the other videos, it will a great tool in studying for the test!

P. S. Did you figure out what was in your atom?


PHYSICS 11-30-12 Power & the Horsepower Lab

PHYSICS: Great job on the horsepower lab. Lotta noise – I’m thinking some of you took out some of your physics phrustrations on the stairs! Post your own horsepower numbers here. Did you notice that not all of the stairs are the same height? BTW: 1 Hp = 746 W and 1 kg = 2.2 lb. Post your lab results here. Who has the most power? And why?

Here’s the lecture from today on power (or rather from last year because I forgot to turn on the mic!). Now go forth and conquer the power problems! Power Worksheet
