Curated OER
Dissolved Oxygen and Temperature
Learners are shown how temperature affects dissolved oxygen and they create a graph showing this relationship. They think about the adaptations of animals to live in different water temperatures. Students test four different water...
Curated OER
Dissolved Oxygen Introduction
High schoolers are shown how dissolved oxygen enters the water. They are taught the difference between a water sample that has been exposed to the air and one that has not. Students brainstorm what organisms need to survive. They use...
Curated OER
Wastewater
Students discuss what happens to their wastewater. They read about the wastewater treatment process. Students are asked what types of things get flushed down toilets or goes down drains in sinks and showers. They are taught what happens...
Curated OER
Aquatic Ecosystem Exploration
Young scholars visit a local stream, pond, creek, or river and collect macroinvertebrates. They sort macroinvertebrates and identify each species using a dichotomous key. Students decide on trophic levels and construct a possible food...

A Design You’ll Dig: Designing a Habitat for Worms
Students discover how worms contribute to the balance of the environment. In this composting lesson, students study the composting and decomposition processes. Students then create habitats for worms that allow them to do their jobs.
Curated OER
Water's Edge Café
Students observe water birds feeding at a local wetland, record what they see, and construct an appropriate menu for a "Waterfowl Cafe." They also play a "flocking" game.
Curated OER
Toward a Sustainable Agriculture
Learners analyze organic production systems. In this organic agriculture lesson, students examine key organic practices for both crop and livestock. This lesson includes 5 different activities, 4 critical thinking questions and...
Curated OER
Global Change- Earth as Home
Students create their own environment. In this environmental protection instructional activity, students pretend they are the owners of a tropical island. They create jobs for the citizens and develop the island as a model environment.
Curated OER
Zoo Poo
Students use Internet research to determine the amount of carbon dioxide produced per unit energy for biomass and coal. In this alternative energy lesson, students research to find out how much energy and carbon dioxide several coal and...
Curated OER
Selecting Soil Organisms in Compost
Students conduct an experiment to demonstrate that many of the enzyme systems needed to break down society's wastes exist in nature among the decomposers in a compost pile. They culture compost bacteria on starch agar to examine the...
Curated OER
Selecting Soil Organisms in Compost
Pupils demonstrate that many of the enzyme systems needed to break down--and therefore clean up-society's wastes already exist in nature among the decomposers. They select the best starch-munching organisms by altering the environment in...
Curated OER
Project Wetlands
Students develop a joint undertaking designed to solve an environmental problem in their local community. They tackle the problem of erosion of banks and chemical run-off into a nearby lake, which is within walking distance of school.
Curated OER
Consider the Issues
Students develop and express opinions on personal and societal issues in biology through journal entries (written and other forms), oral position statements and group discussions.
Curated OER
Water Retention and Soil Variation in Local Ecosystems
Students identify the differences in local soil types and the relationship between soil size and water retention. They are introduced to microenvironmental conditions in ecosystem sustainability.
Curated OER
Introduction to Organisms of the St. Mary's River
Students identify how the tank functions, what organisms are in the tank, and why each component of the tank is important. They are introduced to the organism eelgrass. Students explore the organism Fundulus.
