A CIESE Collaborative Project

Riverside School, Princeton, New Jersey

We sampled water from a pond in Washington Crossing Park.

Our hypothesis was that warmer places would find more types of macroinvertebrates and more of them.  We also hypothesized that the week of warmer weather between the two visits from our school would cause us to find more macroinvertebrates than the previous sampling.


We found:


18 snails and snail eggs
2 Giant Water bugs
18 Water beetles
1 Fishing Spider
4 Dragonfly nymphs
2 Backswimmers
6 Amphipods
24  Mosquito Larvae
2 Damselfly nymphs

We also found 24 tadpoles!
