Middle schoolers consider the interdependency of life in a temperate forest by studying selected organisms from an Asian temperate forest and creating a food web.

Learners explore the interdependence of the animals and plants in tropical rainforests. They explore the importance of conserving biodiversity and tropical food chains. They create a tropical forest food chain and identify species that...

Students identify plants and animals in the journals of Lewis and Clark's expedition. They describe the various animal habits. Students interpret the behaviors of the animals discovered on the expedition. They design a food web using...

Producers, herbivores, carnivores, omnivores, decomposers. To begin a study of the forest ecosystem, learners examine the connections among the members of ecological communities.

Ninth graders complete a unit of lessons on ecosystems, organism interactions, and energy flow. They create a key for known species of fish, diagram the movement of energy through an ecosystem, and create and present food chains and food...

How many animals can live in a climate as cold as Mount Everest's? Find out with a science lesson all about biodiversity. Activities include research, presentations, group work, coloring maps, and a simulation of a food web.

Have your class discuss food chains using this resource. Learners watch a presentation on the food chain and how we are dependent on the smallest life forms. They write newspaper articles and create an illustration describing the food...

Make connections between ocean organisms. Individuals explore three different ecosystems in the ocean. With an online interactive, they learn how different organisms depend upon each other. Learners first answer questions to connect...

Fourth graders discover how organisms depend upon each other in an ecosystem. For this ecosystems lesson, 4th graders use food webs to discuss the interdependence between organisms in an ecosystem.

For this food chain words worksheet, students unscramble the food chain words and then find a hidden word. Students unscramble 14 words total.

Students examine the relationships between plants, animals, and the environment in ecosystems. They sort animal cards, collect natural materials from the schoolyard, and record an ecosystem web in the form of a poster.

Third graders examine the difference between a food web and food chain. They also examine the importance of the sun in a food web and food chain. Students understand what happens when you remove parts of the chain.

Students investigate the components food chains and food webs in various ecosystems. They describe how living things depend on one another for food energy (food chain) and how more than one food chain exists in an ecosystem

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...
