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.

Students create their own monitoring program for natural water. They collect samples from an appropriate sampling site. They perform chemical and biological analyses of their samples. They present their information to the class.

Students set up their own monitoring system. They collect samples from an appropriate sampling site. They analyze data and determine the water quality. They present their information to the class and draw a conclusion.

Students investigate the changes that can take place in an aquatic environment. They conduct research using a variety of resources. The research is used to report different possibilities of change because of abiotic or biotic factors.

Ninth graders debate the positive aspects of dam construction. They discuss how a dam changes the ecosystem. In groups, 9th graders research and gather information for a debate. They state their position and write a report supporting it....

Students investigate the important components for a healthy trout habitat. In this fish habitat lesson, students discuss how the aquarium will simulate a trout's environment in nature. Students complete a trout information sheet to set...

Introduces students to the feeding adaptations found in aquatic macroinvertebrates.

Introduces students to living aquatic macroinvertebrates.

Activity explores major segments of aquatic macroinvertebrates and differences between stages.

In this field lab, small groups of learners will explore macroinvertebrates found in a pond system near school. They will explore and practice observation and communication skills, then formulate a question and procedures to "test" their...

In this hands on activity students will learn how to identify basic macroinvertebrate using a dichotomous key. They will complete a chart used by the MPCA and we will discuss why an ecosystem may not be healthy or not.

During this field activity, young scholars will examine different aquatic habitats, collect and identify macroinvertebrates from each and use an index to determine water quality. They will also be able to explain the meaning of tolerant...

In this outdoor field study, students will collect and identify as many types of macro invertebrates that they find in Lake Bemidji using an identification key. Additionally students will create investigable questions regarding the macro...

Young scholars will learn about water quality indicators.

This simulation can be used to simulate water quality monitoring or to calculate biodiversity.

Students will investigate three aquatic ecosystems (pond, stream, bog) to determine the relative pollution index and the water quality of each ecosystem. They will collect and analyze the benthic organisms found in each system and...

In this unit, young scholars will try to improve stream quality and reduce human impacts by taking action.This Advanced Water Quality unit is packaged into three smaller parts: Part 1: Stream Habitat Assessment; Part 2: Macroinvertebrate...

Students perform a macroinvertebrate survey to gauge the health of a local river. They collect water samples and count macroinvertebrates to learn how the health of a river's ecosystem can be determined by its river insect population.

Students learn what adaptations macroinvertebrates have in order to live in an aquatic environment.

By looking at the bottom dwelling macroinvertebrates, students will investigate water quality and habitat quality in this field lab. Students will record the number of creatures found at the bottom of a pond, lake, ditch, stream or river...

Learning activities allow students to learn about tools for making science observations such as a magnifying lens and ruler. Then students describe how macroinvertebrates are adapted to their aquatic environment.

By the end of this lesson, middle schoolers will understand how we can use macroinvertebrates to determine the quality of water in a river or stream.

This is a comprehensive and detailed site providing information on aquatic macroinvertebrates. The emphasis is on biomonitoring of water quality through quantitative assessment of numbers and types of small aquatic organisms.

For this exercise, students will collect and observe macroinvertebrates in an aquatic system. They will record and summarize their findings.
