Begin with a discussion on vertebrates and invertebrates. Highlight the presence of a backbone in vertebrates and the lack of it in invertebrates.

Introduce the concept of exoskeletons using images of beetles and spiders, explaining their role in protection and structure.

Explain the functions of an exoskeleton in invertebrates, such as providing structure, protection, and preventing water loss.

Discuss the composition and role of chitin in the exoskeletons of insects and crustaceans.

Watch videos on animal structures to understand the adaptations of exoskeletons in various environments.

Engage in a discussion about the process of molting and its importance for growth and development in invertebrates.

Design and build a model of an exoskeleton to explore its protective features. This activity encourages creativity and application of knowledge.

Assign students to research different invertebrates and their exoskeletons, focusing on their unique adaptations.

Use the 'External Structures of Predators and Prey' assessment to evaluate students' understanding of how exoskeletons aid in survival.

Conduct a class discussion on the similarities and differences between vertebrates and invertebrates, focusing on their skeletal structures.

Administer the 'Review – Animal Structures and Functions' assessment to gauge overall comprehension of the topic.

Encourage students to explore further by investigating how exoskeletons inspire human technology and design.
