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! The post on the lab where you’ll post comments with your data is below. You decided today that your data is due posted here by this Tuesday. The entire lab report is due the Tuesday after Thanksgiving.
The report will go in your lab book – Title, Objective, Procedure, Observations (with data table), Conclusion, and Questions. Don’t forget that your graph needs to be drawn on graph paper, folded in half, and attached in your lab book. It can be stapled or taped.

CHEMISTRY: We finally finished the chapter! Did you realize molecules could be that large? And so many of them. But don’t you think polymers are cool? Here’s the lecture from Thursday. Don’t forget the Polymer Worksheet on the back of the syllabus. Put the answers on a sheet of notebook paper.
Some items for contemplation: why are certain plastics recyclable and others not…and what about dishwasher and microwave safe? Hmmmmm…
Here’s the change in schedule for the different chemistry classes:
1st & 2nd Periods: Test changed to after Thanksgiving. HW this weekend CHANGED to Polymer worksheet, finish lab report for Formula of a Hydrate in lab book, AND print and read Lab: Polymers. You’ll answer the polymer lab on the lab sheets.
7th Period: You voted that the test will still be this coming Tuesday. I think that’s a smart thing! HW this weekend is the same as is on the syllabus, although, if I were you, I’d go ahead and print off the polymer lab. We’ll do that lab after the Thanksgiving break.

HON CHEMISTRY: Hey guys! Here’s the Half-life Simulation Lab. Perhaps a bit safer than the real thing? Unless, of course, you’ve taken someone’s M&M’s and then you could have a whole different kind of meltdown! Someone stop me!
Here’s where you post your results. By the way, the numbers to start with that are listed on the lab sheets are strictly examples. I’d start with something like 200 or so, not a whole lot less. 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. You guys decided in class today that your lab results would be due posted as a comment to this post by the Tuesday BEFORE Thanksgiving. The entire lab report, written in your lab book (graph included!) is due Tuesday afternoon AFTER Thanksgiving.
FYI – Just to clarify, everything on the lab sheets will go in your lab book. Title, Objective, Procedure, Observations (with data table), Conclusion, and Questions. Don’t forget that your graph needs to be drawn on graph paper, folded in half, and attached in your lab book. It can be stapled or taped.
Happy counting – and wait until AFTER the lab to snack!! 🙂
