Simulating+estimation+of+populations

Jim: I had never learned the mark and recount method for estimating population size, so I found this interesting. The different colored beads are a nice way to help the students understand how this counting method works.

Deb- this kit seemed interesting but I don't really use this in my class. i will however pass it on to our ecology guy.

Ken - I agree with Deb. Seems like you could do it just as well without purchasing the kit.
