Learners explain how the food chain works. They contrast predators with prey and describe their function in nature. Students discuss how the food chain aids in keeping nature balanced. In small groups, they play a game that simulates the...

Students discover a part of the natural food chain through the dissection of owl pellets. They compare, identify, and record rodent skeletal parts they find in the pellet to skeletal diagrams and try to reconstruct a skeleton from the...

Students s identify the different trophic levels in the food chain and understand the importance of the energy cycle. They create a class food web using index cards and yarn and play a predator/prey game.

Pupils explore the wetlands. They participate in numerous activities to explore food chains, food webs, and energy in the ecosystem. Students read stories, sing songs, visit specified websites, and participate in games to discover...

Students review the basic concepts of the food chain. In small groups, they research an organism and create a food web. In addition, they study biomagnifications and write a brief essay or make a poster informing others about the...

Learners study different aspects of worms along with the process of vermicomposting by participating in a class experiment to study the time it takes for breakfast cereal to be eaten by worms.

Students identify animals observed by Lewis and Clark while evaluating the animal's habitat and describing the animal's behavior. Students construct a food web mobile to illustrate the animal's position in the food web in the 19th...

Students identify the role predators/prey play in food chains, differentiate between food chains and webs, identify factors that affect the balance in food webs, and propose solutions to protect endangered species' environments and...

Second graders examine how food chains interact with different plants and animals. They practice using new vocabulary. They also discover the role of pesticides in the environment.

Students complete a unit of lessons on ecosystems. They participate in online activities, create a diorama, write journal entries, and develop a Hyperstudio multimedia project on a selected ecosystem.

Students participate in an online lesson to determine that different plants and animals are found in different habitats. They use food chains to show feeding relationships in a habitat, and see that nearly all food chains start with a...

Pupils 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.

Fourth graders identify the origins of meats and vegetables consumed by humans on a daily basis. They classify foods (meats, dairy products, grains...) and create a food pyramid.

Students simulate online the formation of Ape Cave, in order to better explain its construction. They observe, illustrate and discuss geological features of this lava tube.

Students examine the concepts in the ecological organization unit.  For this ecological lesson students explore news articles that have to do with the study of ecology. 

Students describe the importance of having a balance ecosystem. After a brief lecture, students give an explanation of the properties of an ecosystem. They create a web, using yarn which shows how the various members of the ecosystem are...

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...

Students compose a visual representation of the food chain cycle using Inspiration educational software.

A module that explains what an ecosystem is and how energy and matter move through them. Students will look at the different roles of plants and animals and at ecological relationships in food chains and food webs.
