Comparing macroinvertebrates in a varety of compost samples

Txiab X, Jordanna M

What kinds of animals live in compost?  We obtained various samples of compost, ranging from the weed pile in our school garden to store-bought to our own classroom-made compost.  We examined the samples for macroinvertebrates, including sowbugs, worms, and insects, and compared density and variety of macroinvertebrates among samples.

Comparing Water Quality: Swamp vs Nearby Vernal Pond

Marianna X, Iren S

Last spring we compared the water quality of two water bodies near our school - a swamp and a vernal, or temporary pond.  We used a multiparameter sonde to collect data about the two sites, including temperature, dissolved oxygen, phytoplankton, and others.  We repeated the testing this fall, and compared our findings to our spring data.

Persistent Puddles or Microponds? Creating artificial ponds to support macroinvertebrate life.

Lor T, Cole S, Jayden T, Jose U

Ponds have a variety of macroinvertebrates that baby fish need to eat.  We are raising trout in our classroom and are interested in these tiny animals.  We have found microinvertebrates in some puddles that dont dry out.  How do these puddles survive and support life?  We tested methods of making puddles to find out.

Plankton Hangouts: Surveying freshwater plankton in a temporary pond

Jeremy R, Steve L, Jevon J

Take a water sample from our school's seasonal pond, and you might get a lot of swimming things or you might not.  Are there plankton hot spots in our pond, or do populations rise and fall over the seasons?  By taking random samples from the edges of the pond, we hope to determine whether plankton populations are spread evenly over our tiny shallow pond or if they tend to concentrate in particular areas.

Sun-loving moss? Comparing shade-loving moss to varieties found on our school baseball diamonds.

Jada L, Ashley T, Elena R

We compared our baseball diamond moss to more typical moss found in the shade around our school.  We put both varieties under strong light and shade to see which had broader tolerance to changing light conditions.  It turns out that moss is more diverse than we had thought!

The Rate of Food Station Recognition among Crows

Yovany S, Sebastian V, Vivian R, Lwe W

Our birding data indicates that crows (Corvus brachyrhychos) are the most common bird species on our school grounds.  How fast can they recognize a food station if we put one out in the playground?  If we move the station on the other side of the school grounds, will they recognize it?  Could crows help us direct other birds to our secure but difficult to find bird feeders?
