Physics 12-2-14 Simple Machines

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!

I’ve decided NOT to add any other information to this test. I’m moving the test back to Monday – the original date. OR we can move tomorrows lab to next week and do the test Friday. Either is okay with me. Let me know how that date works for you.

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 12-2-14 Intro to Atomic Theory

CHEMISTRY: So how do you feel about being made from earth, air, water, and fire? Here’s the very short intro we did on how we ended up with the atomic theory. Had you ever heard of Lavosier, Proust, and Dalton? We’ll continue with Dalton tomorrow!

IMPORTANT NOTE: This is a post from last year, so the beginning info on the recording about the syllabus is not correct.

Any questions about the Sock & Can Model of the Atom? You need to bring to class Thursday a cleaned, empty can like a soup can, etc. It cannot be glass, plastic, or a soft drink can. In the can, place 3 or more random items from your house. Put the can and items into a long sock – the sock must be long enough so that at least six inches or so is left over the top of the can. Tape any sharp edges around your can!! Due Thursday!!!

What about the Carbon Isotope project. Be sure to print and read that sheet to make sure you understand!

Hon Chemistry 12-2-14 Half-Life

HON CHEMISTRY: So what do you figure is the half-life of a banana? But I digress…. Here’s the lecture from Friday on half-life problems. Keep thinking these problems through – listen to the story they’re trying to tell you, and you’ll do great.

Have fun with the half-life simulation lab! Be sure and post your data in the location you guys decided by the time listed on the syllabus. Don’t forget to include pics and your graph! The lab report is to be submitted as a PDF 2X by the due date listed on the syllabus.
