Flow of Energy Through An Ecosystem
In this flow of energy in an ecosystem, students complete a graphic organizer and show the flow of energy from the sun to producers, primary consumers, secondary consumers, tertiary consumers and then decomposers. Students define each of...
Curated OER
Eco-Detectives
Students explore natural decomposers. In this decomposing lesson, students participate in a WebQuest to discover how nature handles decomposition. Students compare natural methods for decomposition with recycling efforts.

Dirty Decomposers
Do not let the class just sit and rot. Pupils learn how decomposition and nutrient recycling is important to an ecosystem. Groups design an experiment to determine how environmental conditions affect decomposition. They develop a poster...

Building A Classroom Food Web
From bears and owls to chipmunks and trees, all life depends on the sun for the energy to survive. Young biologists develop an understanding of this big idea as they arrange this series of plant and animal picture cards into food webs...
Curated OER
Cut and Paste Food Chain
Students study life science. In this food chain lesson, students discover the different types of animals that make up an ecosystem. They discuss as a class and then work independently on a food chain activity. This lesson includes a...

Mighty Microorganisms
How can you tell if a microorganism is helpful or detrimental to an ecosystem? Learners inspect slides or pictures of microorganisms and record their observations to identify those that are beneficial or harmful. They then pretend to...

Understanding Food Chains and Food Webs
Jump into an exploration of marine ecosystems with the first lesson in this four-part series. After first learning about crustaceans, mollusks, and other forms of sea life, young marine biologists view a PowerPoint presentation that...

Matter Cycles — Sum It Up
Scholars become part of the cycle of matter with a reader's theater that showcases producers, consumers, decomposers, and the sun. A diagram and discussion concludes the learning experience and enhances comprehension.

Energy Flow in a Wetland Ecosystem
How is energy transferred within an ecosystem? What would happen to a food web if one of the organisms was removed? Elementary or middle school ecologists examine these questions and more in a comprehensive 5E learning cycle lesson....
Curated OER
Dirty Decomposers
Learners explore the ecosystem by conducting a ziploc bag experiment. In this recycling lesson, students identify decomposer organisms in our environment and how they speed up the recycling process. Learners utilize a ziploc plastic bag,...

Forest Ecosystem
Students become familiar with the temperate rainforest. In this forest ecosystem lesson, students identify the producers, consumers and decomposers in the forest ecosystem. Students sort cards and identify the trophic level of the...
Curated OER
Producers and Energy Transfer
Fifth graders discuss the relationship between producers, consumers, and decomposers as they look at the energy pyramid. While working in small groups, they create an ecosystem that includes all or some of the given categories, and they...
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
Populations and Ecosystems
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.
