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.
