River Model September 8, 2013

This river model is split up into four separate tanks: P1, P2, P3, and P4.

At the beginning of the day, P1 had water, six orange fish, and twenty brown fish. P2 had water, rocks, and two brown fish. P3 had water, rocks, sand, pea gravel, plants, and twenty ghost shrimp. P4 had water, sand, pea gravel, plants, one orange fish, one brown fish, and one blue crayfish. For the rest of the year we will be tracking what fish move where, if any die, or anything else that may occur in a log book. With this river model I hope to learn so much more about rivers.
