Day 57: Radioacitve Decay Lab November 8, 2006

Posted by Admin in Chemistry, Homework.

Each pre-lab was stamped as students entered the classroom today.  Remember, without a stamp, you cannot get full points on homework.  The rate at which students are completing homework by the due date is very weak.  Given that the pre lab would take no longer than 5-10 minutes, excuses are not relevant here.

The data was collected for the Radioactive Decay Lab today and then posted to the front board.  After tallying totals for all groups, the “pooled class data” was then recorded in Table 2 of the lab handout.   This pooled class data is the information that should be graphed on the third page of the lab.

Tomorrow we will work on the Post Lab which will be the 4th and final page of this lab.  Do not lose any pages – you will be stapling all four together and turning them in tomorrow!
