Habitat for Stream Insects
Project EXTREMES lessons were written to be stand alone lessons but can be incorporated into a larger unit.
This activity encourages students to collect data to answer questions, explore the roles of individual macroinvertebrates in aquatic ecosystems, and think about the health of aquatic ecosystems relative to the macroinvertebrates found.Lesson

Population Estimates: Bringing Math and Science Together
Project EXTREMES lessons were written to be stand alone lessons, but this activity may be used prior to a field study to provide students with practice in estimating or used in a unit on ecosystems.
During this activity students will learn how to estimate population size using two techniques, density extrapolation and the mark-recapture method.Lesson
