HON CHEMISTRY: Pretty cool history relating to fission, huh? And what about fusion – just another reason you might not want to plan a trip to the sun!
Guess what? We’ve wrapped up the chapter! How are you doing on studying for the test? It will cover the beginning part of chapter 3 (through average atomic mass), chapter 21, and you will most probably also have a set of chemical formulas to write and name.
Could you use some extra practice? Help session Monday morning when we get back – 7:20ish A.M. (Somebody text me to remind me and I’ll sent a reminder out to everyone!)
Practice everything! And did I mention, PRACTICE!! I’ll be praying for you!

PHYSICS: I love to watch you problem solving together! Since we only did one of the problems on the board, I found a couple of old vodcasts that have others you might find helpful later on.
The first vodcast below is the review of the problems #46 – crate pulled up the incline from the machines homework and #47 – ski acrobat from chapter 5. Below that are the problems #22 – circus monkey on the incline, #21 – diver steps off a diving board, and #46 – a skier is pulled up a slope.

HON CHEMISTRY: Radioactive isotopes all around! Did you ever dream there were so many applications of radioactivity? This is a pic of a test used to check on blood flow through the heart during a stress test. Fun, huh!?
So what’s this about you probably having an radioactive isotope in your house?!? Don’t forget to research how smoke detectors, especially those with Americium, work!

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!
UPDATE: Test the Tuesday or Wednesday when we get back from Thanksgiving break.
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?

HON CHEMISTRY: Wow! We made artificial elements! Well, on paper at least
Are you clear on the Half Life Simulation lab? Be sure and post your data in the special web post for the lab by the correct due date! Check the syllabus for data and lab report due dates.
So you can take something that’s not radioactive and make it radioactive? Here’s the lecture from Friday. Don’t judge me because I don’t know my super heroes!

HON CHEMISTRY: Hey guys – this is where honors chemistry will post results for the Half-Life Simulation lab. You’ll just list your data from the first data table as a comment – just like you comment every week, except this time you are just listing the data from the first data table.
Remember, you don’t have to use candies; you may use coins or anything else that has two sides. Please note that you are to post the number of “radioactive” nuclides remaining after each toss.
Just to clarify, everything on the lab sheets will go in your lab report on that you will submit as a PDF to Google Drive and TurnItIn.com – Title, Objective, Procedure, Observations (with data table), Conclusion, and Questions. Don’t forget that your graph needs to be either a full page graph that you do on Excel or a similar program, or you can draw a full page graph on graph paper, scan a very clean, sharp copy and copy it into your lab report. And don’t forget that the analysis questions, calculations, graph, etc., go after your conclusion.
Happy counting – and wait until AFTER the lab to snack!!

CHEMISTRY: Here’s the help session from this morning. Great practice of several different types of problems that will be on the test.
God bless you as you prepare! I’m praying for you!!

PHYSICS: Great job on the horsepower lab. Not so much noise this time! I’m thinking maybe you don’t have as many physics phrustrations to work out?!?
So how many horsepower do you have? You found Watts? So how many horsepower is that? Hmmmm…..
Here’s the super short lecture from today on power. Now go forth and conquer the power problems!

HON CHEMISTRY: So what do you figure is the half-life of a banana? But I digress…. Here’s the lecture 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 Half Life Lab web post 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.

HON CHEMISTRY: Can you guess what it is?/ It’s a picture of uranium ore under UV light. Cool, huh! Here’s the lecture from today on the first of properties of radioactive nuclides. We’ll finish them tomorrow. Talk about leaving on a cliff hanger!!
