This chapter presents a quick, easy, and inexpensive activity to help students to better understand half-lives. I like the activity and the graphing. I might also have my students do pie graphs for certain points on the graph. For older students you could replace the "decayed atoms" with a different colored "radioactive atom" to show how one radioactive element might go on to a different element which then also decays.

Great graph activity

Students enjoyed this activity, because it is easy to preform. The questions are semi-challenging. If you have students cut out all the (a)s it takes about 45 minutes if you have them already cut out the activity can be completed in about 20 minutes. All levels did very well with this activity and the graphs came out fantastic!
