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 Monday on radioactive decay – nuclear equations and half-life problems.

Don’t forget to memorize the nuclear symbols for alpha particles, beta particles (electrons), positrons, neutrons, and protons. Not nearly as bad as polyatomic ions, huh?!? And great job on half-life problems today! I love the way you were able to figure them out yourselves!! 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. 🙂
