Students research about the process of composting. Students apply their research by creating a compost pile at school that will be maintained once or twice a month for the remainder of the school year.

Students produce a newspaper covering topics related to food webs. They use print and electronic sources to gather information about specific animals. They share their information with the class.

Students explore food chains and food webs in a pond and identify common creatures found in ponds. They look for tadpoles, fish, mites and other creatures in a pond during a field trip for first hand research.

Students explore the predator-prey interactions and how humans have an impact on the food web.  In this food lab lesson plan students complete a food web activity and discuss what they learned. 

Students explore the interconnectedness of living things in an ecosystem. They use pictures and arrows to develop a food web, and participate in constructing a class food web with students representing various parts of the web.

Students explore the elements of a forest ecosystem. They examine the elements needed to form a forest food web. Students construct and describe food webs that include nonliving elements of the ecosystem.

Students are able to define food web, and identify the interdependence of organisms within a system. They are able to describe how natural events and human activities can impact a food web.

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...

Students study the aspects of a forest floor ecosystem, including decomposition, the water cycle, food webs, the needs of living things, and physical vs. chemical change over an extended period. In addition, students conduct observations...

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...

Young scholars examine the species that depend on a poa grass for their habitat and interpret data to demonstrate biomass and number pyramids. They examine the plant by digging it up and pulling it apart quickly to capture all the...

Students interpret data to demonstrate biomass and number pyramids. They use information to draw conclusions and examine an example of biological magnification.

Learners work together to review the concepts of food webs and food chains. They describe the role of plants and animals when dealing with the cycling of energy. They identify any behavioural strategies to help the animals survive.

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 examine how food webs illustrate the ways in which organisms depend on each other for energy and nutrients, and make food webs showing the feeding relationships among organisms encountered in the Gal??pagos coastal waters.

Students will be able to find out about feeding relationships on a coral reef. They then will be able to develop a food chain and food web using coral reef animals and plants using the Coral Website.

Students learn how all living things in an ecosystem are connected in some way. By building their own "web" your class look at energy flow through the food web system and how environmental changes disrupt the system.

Pupils 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...

Students identify features of animals that enable survival in particular environments and group animals on the basis of their similarities. They compare and contrast features of groups of animals.

Students calculate the area of grasslands needed to support a small pride of lions. They also identify food web links in an ecosystem and trace the energy pathways in an ecosystem.

Fifth graders use general knowledge to make educated guesses about the habitat and survival strategies of animals from Australia, Antarctica and Africa. They research to confirm and check ideas and group animals in a variety of ways.

Learners identify characteristics of Australia, Africa and Antarctica and compare and contrast them to each other. They work together to identify adaptations that animals have used to survive. They also practice classifying animals.

Students compare explanations for Australian's megafauna extinctions and identify reasons for popular acceptance of certain scientific explanations. They debate and analyze scientific explanations.
