Seventh graders examine the factors that affect the number and types of organisms that an ecosystem can support.  In this ecosystem lesson students study the barn owl and where it is on the food chain, then dissect an owl pellet.

Learners explore the ecosystem and food chain by researching Pacific Salmon. For this fish habitat lesson, students discover the life cycle for salmon, where they spawn and what they eat to survive the harsh elements. Learners...

Students explore and classify organisms found in a Rocky Mountain Ecosystem. Through discussions, students examine the effects upon an ecosystem if a component was removed or a new component was added. As a class, they survey reasons...

A lab activity is a great way to incite thoughtful questioning and scientific processes. Pupils will collect organisms with a Petri dish, make observations, sketch the organism, ask questions, then attempt to identify the specimen...

One of the key concepts in life science and biology is the cycling of energy throughout an ecosystem. Learners can take notes on the topic using the vocabulary included within the presentation. From producers making their own food...

Students locate 'animals' in various environments and draw conclusions about the survival value of structures the animals possess. They create model macaroni animals and hide them and other teams of students find them and evaluate the...

Fourth graders identify the different habitats found in the seven regions of the United States. In this ecology lesson, 4th graders write an essay about how humans affect the ecosystem and vice versa. They discuss how changes on one...

Students explore animal and plant adaptation.  In this ecosystems science instructional activity, students view websites to gain information about plankton and its  interdependence within ecosystems. Students identify ways in...

How does nature's hierarchy relate to our local human environment? Answer this question, along with others, as the class visually depicts the natural hierarchy provided by nature. Pupils discuss each piece of the pyramid and its energy...

The story of one bird provides valuable insight into general animal behaviors and interactions. Young researchers investigate the peregrine falcon using a web search. They analyze the behaviors of the raptor including its migration...

Do your pupils have the misconception that environmental predators are "bad" and harm smaller creatures? The simulation explains, in detail, the important role predators play in maintaining a stable ecosystem. Through web-based research,...

Pupils role play a living wetland food web. They trace the food web associated with the items in their lunch.

Students create a simulated self-sustaining ecosystem. In this biology lesson, students examine the different food chain and ecosystems in their model. They recommend some improvements and changes to an existing ecosystem.

Students familiarize themselves with the interconnectedness of species within an ecosystem, and to use this knowledge to evaluate how the removal or decimation of one species can have far reaching effects.

Seventh graders create a model of an ecosystem and label it to show structure and function. They research the food web of an aquatic animal and also trace energy flow from the primary producer up the food chain.

Students examine forest food chains and create a forest habitat in the classroom. They are introduced to the concept of interdependence in Nature. They define a simple forest food chain and develop inquiry process skills.

Pupils identify the types of pests and categorize them. They identify their food chain and create a poster showing the food chain for the pests.

In these rainforest vocabulary worksheets, read the definitions and the matching terms for the following rainforest vocabulary terms: decomposers, deforestation, epiphytes, extinct, environment, pollute, vegetation, ecology, climate,...

Students survey local wildlife. They distinguish between permanent and migrating or seasonal species. Students identify species and describe the ecological niche. Students research the food chain and food web for the backyard...

Students, after locating different marine habitats on a globe, play a card game about ecosystems, food webs and organisms.

Students identify the main parts of a coral reef. They describe a coral reef food chain.

High schoolers research and report on the ocean's problems of disappearing or diminishing species around the world. students examine ecosystems and food chains and present their findings to a mock panel of science experts.

Fourth graders observe brine shrimp over several days. They create drawings showing the growth and development of the shrimp. They research web sites to find out where brine shrimp fit on the food chain and what makes the shrimp unique.

Young scholars study the gray whale migration and compare their populations to the increasing ocean temperature.  In this whale watcher lesson plan students draw a food chain.
