Begin the lesson by introducing students to the fascinating world of sponges, some of the oldest and simplest animals on Earth. Discuss their unique characteristics, such as their asymmetrical bodies and lack of tissues and organs.

Explain the feeding mechanism of sponges as filter-feeders. Highlight the role of pores and collar cells in their survival and how they rely on a constant flow of water to obtain food and oxygen.

Discuss the environments where sponges can be found, including both marine and freshwater habitats. Use visuals to illustrate the diversity of sponge habitats.

Watch the video 'All About Sponges' to gain a deeper understanding of their structure, feeding process, and reproductive methods. This video visually depicts how sponges filter water and reproduce, enhancing comprehension.

Engage students in a hands-on activity where they create a model of a sponge's filter-feeding mechanism using simple materials. This will help them visualize and understand how sponges filter water.

Assign the 'Sponges Fact Sheet' assessment where students identify sponges from images and answer questions about their habitats, diets, and reproduction methods. This activity promotes critical thinking and research skills.

Conduct a class discussion to check for understanding. Ask students to explain the role of collar cells in sponges and how these cells contribute to their survival.

Review the key concepts learned about sponges, including their structure, feeding mechanism, and habitats. Encourage students to reflect on what they found most interesting about sponges.

Use the 'Classifying Animals in the Schoolyard' assessment to extend learning. Students will classify animals based on observed characteristics, reinforcing their understanding of animal classification.

Conclude the lesson with a quiz to assess students' comprehension of the topic. This will help identify areas that may need further clarification.
