Aquatic Life (6-8)
Macroinvertebrates are bugs that live in water that are invertebrates (meaning they have no backbone) and are visible to the naked eye. They are also bioindicators (short for biological indicators) and can help scientists determine the health of a river or stream. Some macroinvertebrates are more pollution sensitive than others, and the presence or absence of certain species can help determine a stream's health/level of pollution.
