Hon Chemistry Half-Life Simulation Lab

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!! πŸ™‚

Chemistry 1-9-12 Half-Life Review & Applications of Radioactivity

CHEMISTRY: Happy Monday! How are you doing with the half-life problems? Some were ok/easy, from last night, but a couple of them, number 28 and 43 (I think) were kind of unusual to think though. Practice them over and over, even if it’s the same problems. The practice will help you learn to think your way through them.

Well, we didn’t get to talk much about applications of radioactive isotopes, so let’s continue that tomorrow. Good luck finishing up the half-life lab. The due date has been changed. Your lab books are due Wednesday.

Chemistry 1-6-12 Half-Life Problems

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!) Here’s the lecture from Friday on half-life problems. Keep thinking them through and you’ll do great!

1st Period Chem Half-Life Simulation Lab – Part 2

Hey guys – this is where 1st Period Chemistry posts results for the Half-Life Simulation lab. You’ll just list your data from the second data table as a comment – just like you comment every week, except this time you are just listing the data from the second data table. Don’t forget that your results must be posted by next Monday, Jan. 9, by 5:00 P.M. The lab report will be due written up in your lab book on Tuesday, Jan. 10.

Remember, the number of particles to start with that are listed on the lab sheets are strictly examples. You must with something like 200 or so. 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 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 (neatly, nothing sticking out of the lab book). And don’t forget that the analysis questions, calculations, graph, etc., go after your conclusion.

Chemistry Half-Life Simulation Lab – Part 1

CHEMISTRY: Hey guys! Here’s where you can find the first info on the Half-life Simulation Lab. It’s 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!

This is just the first post, you’ll post your results under a second post that will be just for your class period. I’ll probably write that post around Monday or so. Don’t forget that your results must be posted by next Friday, Jan. 11, by midnight on the post for YOUR CLASS – not this post (and yes, that can be your webpost for the week!). The lab report will be due written up in your lab book on Monday, Jan. 14.

By the way, 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.

Hon Chemistry 12-6-11 Applications of Radioactivity

HON CHEMISTRY: Hmmmmm…..so what do you do when you forget to upload the day’s lesson to blip.tv? You post an old lecture from another year! This actually might turn out to be a good thing – the beginning of this old lecture has some half-life problems practice that might turn out to be useful for you. As for the rest – it doesn’t have everything, but it does have most of the applications that we talked about today in class.

So it turns out there are some pretty useful applications of radioactivity! Let’s finish talking about fission and fusion tomorrow, okay? Oh, and help session tomorrow morning, 7:15ish A.M.

Hon Chemistry 12-2-11 Half-Life Problems

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. (I’m still not sure what happened to the Power Point!) Keep thinking these problems through and you’ll do great!

Have fun with the half-life simulation lab! 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.
