The text is converted as it appears on the sign, obviously written by the school children themselves. There is a photo of an aquaric worm, the stream itself, and a scud
Macroinvertebrates
types of macroinvertebrates.
There are many types of macroinvertebrates.
Macroinvertebrates help the ecosystem grow. Here are some of the types of macroinvertebrates; larvae, scud, leeches, and snails. Larvae is a type of group with mayflies, stoneflies exc. Scuds look a little like shrimp and swim on their side. Leeches are blood sucking worms that can suck your blood from the front and back. Finally, snails are hard-shelled creatures. That have one opening in their shell.

Tolerances
Macroinvertebrates are different in many ways. For example, some are pollution tolerant and some are pollution sensitive. There are also ones that are somewhat sensitive. This means that some are more sensitive and some are less so, some are more likely to die than others. If a stream has more pollution sensitive macroinvertebrates, then That means that the stream is healthy because if their macroinvertebrates like a mayfly or a caddisfly they are sensitive to polluted water so if they are still alive then the stream is healthy. The pollution tolerant ones are aquatic worms, blackflies, leeches, midges, snails, and mosquito larvae. The pollution intolerant ones are the caddisfly, mayfly, riffle beetle, stonefly, water penny, and the dobsonfly. There are also somewhat sensitive macros, like clam/mussel, crane fly, crayfish, damselfly, dragonfly, scud, fishfly, alderfly and mite. Bryant Elementary 5th grade classes class tested the water of Ravena Creek this fall to see how healthy it was. We found more sensitive macroinvertebrates than tolerant ones, which mean…
Elementary school sign in the park along the stream bed: the kids wrote up a nice set of signs with various insights about local ecology. This is the first one of the series. Spelling and wording totally their own
