Beetle Collection and Release
Young scholars investigate plants and compare them to the purple loose strife. As they observe the plants they predict possible impacts on plant populations based on their observations. They work in groups and present their findings to...
Curated OER
Organisms and Their Environment
Young scholars explore Earth's biosphere. For this biosphere lesson, students participate in group activities regarding biotic and abiotic factors, population density, and species' habitats.
Curated OER
Deer Population
Ninth graders study deer including their reproduction rate and management in Pennsylvania. In this deer overpopulation lesson plan students estimate deer population and suggest management tools.
Curated OER
Oh, What a Tangled Web We Weave
Fifth graders investigate the food chain by viewing video clips. In this food web lesson, 5th graders investigate populations and ecosystems by viewing a video in class as well as visiting web sites. Students utilize the Internet to...
Curated OER
Spring of Life
Pupils explore Florida's springs using video segments. In this video lesson plan, students examine Florida's springs ecosystem, the animals that live there and the red tide that threatens the environment. The lesson plan includes...
Curated OER
Predator/Prey Relationship
Middle schoolers study and analyze data collected on the relationship between the snowshoe hare and lynx in Canada over a 28 year period and create a graph. Students also write a response to a proposal to reduce the lynx population.
Curated OER
The Trouble with Crayfish
Fourth graders compare an ecosystem before and after they introduce crayfish to that ecosystem. In this ecosystem lesson plan, 4th graders see what happens when you introduce a non native animal to a habitat. Students then make...
Curated OER
The Captain And Lake Wilmar
Tenth graders examine the ecosystem of Lake Wilmar through three coordinated performance tasks. They first investigate the effects of pH on freshwater animals by comparing the zooplankton counts from three different areas. They then...
Curated OER
Web of Life
Students collect information about various organisms in a forest ecosystem and create a mural that depicts organism interdependence. They then simulate a food web using a ball of string.
Curated OER
Filling Up Florida
Students study factors controlling Florida's population growth and related environmental impacts. They research natural community types and construct maps (including a large-sized map of Florida) to be used for a simulation activity.
Curated OER
Food for Thought
Students explore the food chains in a variety of ecosystems and its relationship to the survival of threatened or endangered marine animals or fish in the ocean. The interdependence of the species is investigated in this lesson.
Curated OER
The Mechanisms of Decay and Decomposition
Eighth graders study how all living things die. They are introduced tot he life cycle and the concept of an ecosystem. Students have a introductory exposure to trophic levels (producer-consumer-decomposer) in the environment.
Curated OER
Norman Suburban Activity
Students analyze the factors affecting organisms in the pond ecosystem. In this environmental science instructional activity, students perform an experiment to determine pH, nutrients and temperature of different pond sites. They present...

Investigating Space Requirement of Seed Plants
Learners use scientific methods to investigate the effects of overpopulation of seed plants on growth in a limited living space. Students relate seed plant population findings to that of other organisms.
Curated OER
Animals in the Wild
Learners explore the role of snakes in an ecosystem and discover how snakes warn us that they are dangerous. They view and discuss a Discovery Channel video showcasing snakes in the wild then break into small groups to research a...

Zebra Mussel Population Simulation
Pupils are taught how to format and enter data into an Excel spreadsheet. They make a graph, and interpret graphed data. Students discuss the possible impacts of zebra mussels on the Hudson river. They graph zebra mussel data.
Curated OER
The Portable Niche
Third graders, in groups, research animals, plants, and conditions found in ecosystems.
Curated OER
Ecological Relationships
Students identify ecological elements and their factors on species, populations and food webs. They analyze ecosystems for these elements and research how these factors influence species survival rate. Predictions on conditions over time...
Curated OER
The Rainforest Community
Young scholars create a miniature rainforest ecosystem, a terrarium. Students then explain how the continuous flow of energy and food in the ecosystem allows it to sustain itself.
Curated OER
Interactions Among Living Things
Students role play predators and prey, classify organisms as predator or prey, and describe factors that affect population growth and size.
