HON CHEMISTRY: Welcome to nuclear chemistry! No, really – I think you’ll be surprised how much nuclear chemistry is already a part of your everyday life. And now you know where E=mc2 came from!!
Here’s the lecture fOR Wednesday on a bit of the “history” of radioactivity. By the way, when you get a chance, read about the life of Marie Cure – fascinating woman of science with an incredible story!

PHYSICS: Wow! Do you realize what we just did? We finished the chapter! Well, we’ll add this small lecture on simple machines from chapter 7 to the chapter 5 test – but we’re done!
Did you remember this stuff on simple machines from your physical science days? I don’t think you’ll have any trouble with efficiency and mechanical advantage problems. Give them a whirl and let me know!
How do you think the efficiencies of machines compare? Could you design a method to test that? You don’t need no stinkin’ lab sheets! Do you?

CHEMISTRY: Here is the virtual lab assignment for Wednesday and Thursday. It is the vLAB: Determining an Empirical Formula. You will also do Extension 1. The assignment is due Monday, Dec. 5, by midnight – save sheets as PDF 2X.
Be sure and use the lab sheets here and NOT sheets on the textbook site that come with the virtual lab! Ask Mrs. Jackie to get you the headphones if you don’t have your own ear buds.
Also be sure and save your work on Wednesday so you don’t have to start over! Hint: Copy the sheets from the Word doc to a Google Doc so that you can save your work and keep working on it the next day! Here’s how:
Be sure and listen to and/or read all of the parts of the lab carefully!!
