Learners discuss the different types of ecosystems and the composition of biomes. Working in groups, they define various related terms and make posters of them. Then they explain their posters to the class.

Fourth graders see how the flow of energy through an ecosystem made up of producers, consumers, and decomposers carries out the processes of life and that some energy dissipates as heat and is not recycled.

Students explore the characteristics of major ecosystems, the interactions of the organisms within the systems, and the effects of humans on the system. Both living and non-living components are examined in this five lesson unit.

Students examine the concepts of ecosystems and interdependence. They construct block pyramids to demonstrate interdependence, and map off an area to observe and identify animals. They create food chain mobiles and play a web of life game.

Students explore the freshwater ecosystem of Africa's Lake Victoria by creating a freshwater aquarium. They investigate factors affecting the aquarium's ecosystem and conduct lab activities.

Students are introduced to the concepts of ecology and ecosystems. In groups, they use the Internet to research one of six topics. They present their information to the class sharing the most interesting information they found. They...

Learners explore the water cycle. In this investigative lesson, students examine the water cycle process. They will record their observations and discuss marine and freshwater ecosystems.

Fourth graders investigate ecosystems. In this ecosystem lesson, 4th graders explore producers, consumers, and decomposers and study the interdependence of each.

Ninth graders discuss the principal source of energy entering the marine ecosystem. They name some of the autotrophs at the Maui Ocean Center. Students name some of the heterotrophs at Maui Ocean Center. They are taught that plants are...

Second graders observe images of prairie ecosystems and discuss the needs of living things. They create a prairie habitat in a closed jar to observe the water cycle and plant growth.

Roll up your sleeves and get a little dirty with this elementary and middle school compost lesson. All you need is a large plastic container, a couple old newspapers, some organic waste, and a few hundred worms and you're ready...

A small little ant can have a large impact on its ecosystem. Young researchers explore the different species that live in a plains ecosystem. They find the characteristics of several species and then compare species to determine how...

Students explore decay in ecosystems by investigating a rotting log and/orcreating a decomposition chamber. They make predictions and answer questions about the changes involved.

Students gain understanding of several of the biogeochemical processes in microbial mats. They acquire knowledge of the different roles of organisms in a microbial mat ecosystem. They understand how microbial mat ecosystems contributed...

Beginning biologists demonstrate their grasp on cellular respiration, photosynthesis, and energy flow though ecosystems when completing this worksheet. Fifteen multiple choice and short answer questions test their knowledge. Because of...

Seventh graders examine proper journaling techniques, and record observations about at tree after listening to a read aloud of "Four Worlds: The Dine Story of Creation." They study the difference between living and non-living things, and...

Students explore the concept of sediment pollution. In this erosion lesson, students discuss the process of erosion and determine how sediment pollution affects animals that live in freshwater ecosystems. Students respond to questions...

Tenth graders are introduced to the process of succession and gain awareness of the changing nature of ecosystems. They demonstrate a comprehension of the dynamic nature of ecosystems, including the relationship between ecological...

In this ecological succession worksheet, high schoolers answer questions about the process of succession in four ponds given diagrams and descriptions.

Young scholars 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.

Students identify predator/prey relationships based on the food web of the tropical rain forest ecosystem and realize they need a food web for survival. In this food web lesson plan, students complete a role play activity being animals...

Students work in groups to locate an appropriate planet where inhabitants of a fictional place can be relocated. They create a PowerPoint presentation to introduce their relocation site, as well as ecosystem information about the site....

In this biotic and abiotic factors worksheet, students complete 20 various types of questions related to biotic and abiotic factors. First, they write the vocabulary word that best completes the sentence. Then, students state an example...

Students investigate how worms affect plant growth.  In this biology lesson, students construct a worm ecosystem in a plastic 2 liter bottle and plant a seed in the soil.  They later compare the ecosystems with worms to ones...
