Begin the lesson by introducing the diverse world of mammals, highlighting their unique characteristics such as endothermy and internal temperature regulation. Use the 'All About Mammals' video to provide an engaging overview of mammalian traits and adaptations.

Discuss the reproductive processes of mammals, emphasizing live birth and the exceptions of egg-laying species like the echidna and platypus. Use the 'Australia's Top 5 Mammals' video to explore these unique species and their adaptations.

Explain the function of mammary glands in female mammals and their role in nurturing offspring. Highlight the significance of this adaptation in mammalian survival.

Explore the respiratory process in mammals and how it adapts across different environments. Use the 'Marine Mammals' video to illustrate how aquatic mammals like dolphins and whales breathe.

Discuss the parental care behaviors exhibited by mammals and their role in offspring survival. Use examples of mammals teaching their young survival skills.

Conduct a classification activity where students sort different animals into mammal and non-mammal categories based on their characteristics.

Use the 'Animal Classification – Mammals' assessment to reinforce students' understanding of mammalian traits and adaptations.

Assign students to research a specific mammal and present its unique adaptations and behaviors to the class.

Use the 'Gas Exchange' assessment to evaluate students' understanding of respiratory adaptations in mammals.

Facilitate a class discussion reflecting on the importance of mammalian adaptations for survival and their ecological roles.

Conclude the unit with a quiz to assess comprehension of the key concepts covered in the lesson.

For further exploration, students can watch the 'Intelligent Creatures' video to learn about the cognitive abilities of mammals like dolphins and elephants.
