Thoughts on Radioactive Decay Lab

I found this lab useful because we cut a piece of paper, that was colored on one side only, into over 500 pieces. We then continued to place them in a cup, dump them out and count how many landed with the color side up. These were the "atoms" that decayed, so they were taken out and the process was repeated 5 more times. This lab really helped me put a visual in my head to radioactive decay and how it occurs. It was also fun to touch on forensic science in a way as we had to identify a body based on the amount of the certain substance left after 60 years.
