Stream Macroinvertebrate
Sampling Simulation—
Super Value Kit
By: The Flinn Staff
What is the water quality of this stream? Is
it polluted? Students use a sample of illustrated
macroinvertebrates to determine
the Biotic Index and the water quality of a
simulated natural water source. Students
also use the illustrated macroinvertebrates
to learn how some populations are estimated in the wild using a common
technique known as mark-and-recapture. Complete with valuable Teacher Notes,
reproducible student handouts and illustrated macroinvertebrates.
Super Value Kit is complete for 10 student groups. All materials are reusable.
