Hey guys – this is where 4th 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.

Happy counting – and wait until AFTER the lab to snack!! 🙂
