Well, the kids are excited.! Our guppies and pond snails arrived yesterday and have found their new homes in the aqauriums on the student's desks, (no spills yet!).  Each group has a few male and female guppies in their tanks.  This morning, several kids were just sure they had babies born during the night, just because the guppies are so small.  I have to remind them, that those were the same guppies, no new ones yet.  Hopefully during the course of this unit we will get to see the life cycle. :)
