This web site and chart show many radioactive isotopes. There is a
teacher manual also.
http://www.lbl.gov/abc/

You can click on any element and see info about all of its isotopes at:
http://ie.lbl.gov/education/isotopes.htm

Students could investigate to see if there is a pattern of what is
radioactive and what is stable.
