Begin the lesson by discussing the various climates animals inhabit, from the icy Antarctic to the warm Serengeti. Introduce the concept of group living as a survival strategy in cold environments.

Engage students with questions: What are some animals that form groups? How does forming a group help them survive?

Explain how emperor penguins huddle together to conserve heat and survive the extreme cold of the Antarctic.

Discuss the formation behavior of musk oxen in the Arctic tundra for warmth and protection.

Watch the video 'Why Do Animals Form Groups?' to understand the advantages of group living, such as warmth retention and predator evasion.

Facilitate a discussion on how these behaviors are adaptations for survival in different environments.

Have students simulate the huddling behavior of emperor penguins using a classroom activity. Students can take turns being in the center and on the outside of the group.

Encourage students to draw and label a diagram of a musk oxen herd formation, highlighting the protective circle.

Assign the assessment 'Evidence and Explanations – Animal Groups' to reinforce understanding of group behaviors aiding survival.

Conduct a quick quiz to assess students' understanding of how group living helps animals survive in cold environments.

Have students reflect on what they learned about animal adaptations for survival. Discuss how these strategies might be applied in other environments.

Use the 'Review – Adaptations for Survival' assessment to evaluate students' understanding of adaptations in various habitats.

Encourage students to research another animal that uses group living as a survival strategy and present their findings to the class.
