Hey guys – this is where 7th Period Chemistry posts 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. Don’t forget that your results must be posted by Friday, Jan. 9, by midnight. The lab report is due written up in your lab book on Tuesday, Jan. 13.

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 post on Google Drive (from now on this is your lab book). 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: Now here’s a healthy breakfast! So what do you figure is the half-life of a twinkie? Nooooooooo…..it’s not the same thing! (Even it you do eat it with a Red Bull!)

So how are you doing with the nuclear equations? Feeling better about them now? Make sure you memorize the nuclear symbols for alpha particles, beta particles (electrons), positrons, neutrons, and protons!

Great start on half-life problems! These will be a little different – we thought them through in class, now I want you to take the concepts we talked about and work them. We’ll walk through them tomorrow in class, I promise, but first, I want you to think through these problems yourselves! You’re a great problem solver!

CHEMISTRY: So ordinarily it looks like just any old hunk of rock, but this is a picture of uranium ore under UV light. Pretty cool, huh?!? Here’s the lecture on the properties of radioactive nuclides and our beginning discussion on the types of radioactive decay.

Don’t forget to memorize the nuclear symbols for alpha particles, beta particles (electrons), positrons, neutrons, and protons – you will need them to write nuclear equations. I don’t think it will be nearly as bad as polyatomic ions!
🙂

Have any of you decided you want to get a head start on the half-life simulation lab? Don’t let it stress you out! It’s one of easiest labs you’ve done, but it does require that you READ the instructions on the syllabus and the website (The post on the website will be up soon, be sure and look for it.). If there is something you still don’t understand, make sure you ask me, I’ll be glad to help! And speaking of half-life, let’s do some calculating tomorrow. Calculators ready!

CHEMISTRY: Happy new year and welcome to nuclear chemistry! Lots of cool history, and I think you’ll be surprised how much nuclear chemistry is already a part of your everyday life. Also now you know where E=mc2 came from!!

Have you got a copy of the syllabus yet? It’s very important that you read it carefully – especially so you’ll know what to do about the half-life lab.

By the way, you ought to read about the life of Marie Cure. Fascinating woman of science with an incredible story!
