Benthic Macroinvertebrates

How diverse are the benthic organisms found in local streams? Using the information learned in previous lessons on identification of macroinvertebrates and on calculating stream index values, groups determine the health of local streams....

What kind of organisms are living in the stream? After an explanation on how to use a dichotomous key, groups of three to four use the keys to identify macroinvertebrates from a local freshwater stream. Using the the concept of Stream...

Do golf courses affect the water organisms in nearby streams and ponds? Small groups collect samples of water upstream and downstream from a golf course and analyze the macroinvertebrates found and the stream index values of the two...

Learners discuss water clarity and how the environment can affect it. They perform experiments to check the readings of the water depth and measure water clarity. Learners discuss vocabulary words, record their observations and examine...

Field study groups collect samples of stream water and identify the macroinvertebrates found. Using their data, they calculate a water quality index to rate the health of the stream. They graph their data and discuss the value of a water...

Students examine water samples from a local stream. They identify various types of macroinvertebrates found in that water ecosystem and perform a quantitative macroinvertebrate survey to determine the stream's water quality.

Students conduct an experiment using leaf packs.  In this leaf lesson students complete an activity in groups and complete a handout. 

Students study outside sources of energy that are associated with the headwater streams in northern Michigan. They study how leaf fall is an important food source for macroinvertebrates and how photosynthesis drives the production of...

Students search stream beds to study the life cycle and adaptations of stream insects. They explore creeks and streams to see the diversity index of creeks or streams and to find the water qualit index.

Learners measure the clarity of a body of water and identify possible environmental complications that can be attributed to clarity and turbidity.
