Hon Chemistry Half-Life Simulation Lab

Posted on by

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!! 🙂

HON CHEMISTRY: So what do you figure is the half-life of a banana? But I digress…. Here’s the lecture for 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 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. 🙂

PHYSICS: I wish I could watch you problem solving together! Here’s a head start (if you need it!) –

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.

Chemistry 12-1-17 Polymers

Posted on by

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 for Friday. Don’t forget the Polymer Worksheet! Put the answers on sheets of notebook paper.

BEGIN WATCHING THIS VODCAST AT 6::00 MINUTES.

Some items for contemplation: why are certain plastics recyclable and others not…and what about dishwasher and microwave safe? Hmmmmm…
