What kind of activities/experiments could I do?

[Wild West]

I will be teaching a sociobiology unit for an Advanced Biology class soon for two weeks and was wondering if you could let me know about any interesting experiments or activities I can do with them involving heirarchy, choosing mates, revealing advantages and disadvantages to group living, etc.

So if you have anything please leave either the experiment and a thorough description or a website for it.

Thanks!
