Curated OER
Biological Relationships
Create a written document to show knowledge of producers, consumers, decomposers, and symbiotic relationships. To investigate food consumption, your classes will differentiate between types of symbiosis and explain examples of each.
Curated OER
Producers, Consumers, Decomposers (3-5)
Students gather evidence to explain that organisms in an ecosystem are tied together by their need for energy. They see that decomposers break down dead organisms and wastes and release the nutrients they contain into the soil,
Curated OER
Who Am I?
Young scholars classify organisms into one of five categories: producer, consumer, decomposer, predator, or prey. Students play a "Who Am I" game. Signs are hung on the backs of fellow young scholars They must ask questions to determine...
Science Matters
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.Â
Curated OER
it's Lonely At The Top
Students explore the differnences between food producers in food webs and food consumers in food chains. Behavioral choices of primary and secondary consumers such as herbivores, vegetarians, carnivors, and omnivors are analyzed.
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
Food Chains
Fourth graders study food chains, producers, consumers, and decomposers. They play a food chain game and create food chain mobiles or posters. They take a nature hike around the school and observe various parts of a food chain.
Curated OER
Producers and Consumers
Learners make lists of producers and consumers and act as consumers that eat producers in a garden. In this producers and consumers lesson plan, students demonstrate a food chain by using a piece of yarn to connect all of them together.
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.

An Ocean of Energy
Young biologists trace the path of the sun's energy through marine ecosystems in the second part of this four-lesson series. Building on prior knowledge about producers, consumers, and decomposers young scholars are introduced to the...
Curated OER
A Dog Eat Dog World
Fourth graders distinguish between acquatic and terrestrial organisms. They label animals as producers, consumers, and/or decomposers.
Curated OER
Ecosystem Game
Students examine the ecosystem by playing a game. In this ecosystem lesson, students are put into groups of decomposers, consumers, and producers. Students create a list of animals that fit into each group and items that represent...
Curated OER
An Introduction to the Ocean World
Students comprehend how the organisms that exist within the ocean biome, and categorizing each into producer, consumer, or decomposer. They place various human actions under the headings of "hazard" or "help," illustrating how humans can...
Curated OER
Mini-Ponds
In this mini pond worksheet, students create a mini-pond ecosystem with soil, water, and plant life. Students let their ecosystem sit for a day and they observe a sample the next day. Students identify all the pond water microorganisms...

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...
Curated OER
Prairie Food Chains & Webs
Students complete a food chain. For this ecosystem lesson, students learn about producers, consumers and decomposers. Students identify herbivores, carnivores and omnivores and complete two worksheets.
Curated OER
Forest Food Webs
Students consider the interdependency of life in a temperate forest by studying selected organisms from an Asian temperate forest and creating a food web.
Curated OER
The Flow of Energy Song
Students perform the lyrics and instrumental parts for the "Flow of Energy song." They create photo images which represent consumers, producers, decomposers, and scavengers. These images will be inserted in an iMovie of the class...
Curated OER
Composting
Using 2-liter bottles, junior ecologists create composting tubes in which they place nitrogen-rich and carbon-rich materials. They observe what changes occur over two weeks' time. Provide more specific direction to your class as to what...
Curated OER
Drama in the Salt Marsh
Students are introduced to the various organisms that live in a salt marsh. They recognize adaptations of organisms that live in the salt marsh. Pupils review concepts of the ecosystem and niche. Students explain the different roles...
Curated OER
Food Webs
Students research rainforest animals and use that information to make a flow chart to show the order in which energy is transferred through several organisms. They label the producers, consumers, and decomposers in their chart.
Science Matters
Energy Flow
Budding scientists work collaboratively to reenact energy flow in a food chain. Scholars take on roles such as producer and consumer and perform tasks that symbolize energy flow in order to provide evidence of how much energy passes...

Fuel Cell Experimentation
With rising oil prices and increasing concerns over global warming, the pressure is on for engineers to develop alternative sources of energy. Among the new technologies being developed are hydrogen fuel cells, which young scientists...
