Reflection: Grappling with Complexity Macros in our Stream System - Section 3: Class Discussion


I use a class discussion at the end of the lesson to accomplish three goals. First, a class discussion allows students to share their findings with one another. Students can record their own findings and those of their peers to make their lab report complete. Second, a class discussion allows us the classify the macxroinvertebrates we idenitfied as either polltuion tolerant or pollution sensistive. Being able to sort macroinvertebrates into these two broad categories enables us to make judgments about water quality in this and future lessons. Finally, the class discussion allows us to collaboratively draw conclusions about the quality of the water in our local stream.

Macros in our Stream System

Unit 5: Macroinvertebrates
Lesson 5 of 6

Objective: SWBAT identify various species of macroinvertebrates and classify them by pollution tolerance.

Big Idea: Students will make judgments about water quality based on the macroinvertebrate species they identify.
