Begin the lesson by introducing the concept of animal classification. Explain that animals are divided into two main groups: vertebrates and invertebrates. Highlight the diversity of animal life on Earth, from the freezing poles to the hottest deserts.

Explain the characteristics that differentiate vertebrates from invertebrates. Discuss examples of vertebrates like fish, amphibians, reptiles, birds, and mammals, and invertebrates like sponges, jellyfish, sea stars, snails, and insects.

Use the video 'Classification of Animals' to provide a visual explanation of the classification process. This video supports understanding by illustrating how these classifications help scientists study and organize the vast diversity of animal life.

Engage students with the video 'Endangered Animals – Quiz Edition' to explore the challenges faced by endangered species. This video combines educational content with a quiz to reinforce learning and encourage active participation in conservation efforts.

Discuss the basic differences in habitats and energy sources between animals and plants, emphasizing that animals feed on other organisms for energy.

Conduct a classification activity where students sort images of animals into vertebrates and invertebrates. This hands-on approach helps solidify their understanding of animal classification.

Use the 'Classifying Animals in the Schoolyard' assessment to engage students in group activities, encouraging them to classify animals based on observed characteristics.

Assign the 'Invertebrates' assessment for students to complete independently. This activity promotes engagement through visual identification and helps assess students' understanding of invertebrate characteristics and classification.

Use the 'Review – Animal Classification' assessment to check students' understanding of the differences between vertebrates and invertebrates. This worksheet engages students with activities like comparing and contrasting these groups using a Venn diagram.

Facilitate a class discussion to reflect on what students have learned about animal classification. Encourage them to share interesting facts they discovered during the lesson.

Conclude the lesson with the 'Animal Classification' assessment pack for a comprehensive review. This pack includes answer keys for easy correction.

Encourage students to take the unit quiz to test their comprehension of the topic.
