Begin the lesson by introducing the fascinating journey of a salmon's life cycle. Engage students with a story about how female salmon lay their eggs in gravelly spawning grounds and the journey these eggs take to become adult salmon.

Discuss the stages of a salmon's life cycle, emphasizing the role of the yolk sac in the early development of salmon fry and the significance of the juvenile stage.

Use the video 'All About Fish' to provide visual context and support understanding of the biological and ecological aspects of fish.

Encourage students to explore different fish species and their life cycles, noting the variations in patterns and stages.

Watch the video 'All About Fish' to further explore the classification of fish into jawless, cartilaginous, and bony fish, and their unique adaptations.

Have students create a visual representation of a salmon's life cycle, labeling each stage and describing the key characteristics.

Assign students to research and present on a different fish species, focusing on its life cycle and any unique adaptations it may have.

Use the assessment 'Characteristics and Life Cycles of Fish' to evaluate students' understanding of the stages of a salmon's life cycle and their ability to differentiate between fish and mammals.

Reflect on the importance of each life cycle stage and how it contributes to the survival and reproduction of fish.

Use the 'Review – All About Animals' assessment to compare the needs of plants and animals, and categorize animals based on body covering and reproduction.
