A CIESE Collaborative Project

Frank J. Smith School, East Hanover, New Jersey

Our class hypothesis was that:

We believe that the macro invertebrates we discover in our pond sample will not be the same in all pond water samples.

We came up with this hypothesis because we felt that the climate is different in other places compared to ours which could affect the lives of certain macro invertebrates.

We then collected our pond sample from Burnham Pond in New Jersey and made many observations using various tools such as: popsicle sticks, magnifying glasses, a microscope, and eye droppers.

During our observations of macro invertebrates we found: scuds (amphipods), bristle worms, mayfly nymphs, dragonfly nymphs, snails, damselfly nymphs, and midge larva.

Some macro invertebrates we found that were not on the identification guide were: tadpoles, tadpole eggs, Crain fly larva, water boatman, and we believe some type of water beetle as well.

We also observed much plant life too! Some plant life we saw was algae (and lots of it!) and some different types of pond grasses too.

We look forward to testing our hypothesis soon!
