Begin the lesson with an engaging video that introduces echinoderms, highlighting their unique characteristics and habitats.

Discuss the diversity of echinoderms and their ecological roles in marine environments.

Explain the key characteristics of echinoderms, including their endoskeletons and tube feet.

Introduce the different types of echinoderms such as sea stars, brittle stars, sea urchins, and sea cucumbers.

Explore the reproduction methods of echinoderms, focusing on both sexual and asexual reproduction.

Use diagrams to illustrate the process of fragmentation and regeneration in sea stars.

Conduct a classification activity where students sort images of echinoderms based on their physical characteristics.

Use the 'Echinoderms Fact Sheet' to help students identify and understand echinoderm characteristics.

Assign students to research one type of echinoderm and present their findings to the class.

Encourage students to create a poster or digital presentation on their chosen echinoderm.

Facilitate a class discussion to review the key characteristics and reproduction methods of echinoderms.

Ask students to compare and contrast different echinoderms based on their research.

Have students reflect on what they found most interesting about echinoderms and their ecological roles.

Encourage students to share their reflections in small groups or as a class.

Use the 'Classifying Animals in the Schoolyard' assessment to evaluate students' understanding of animal classification.

Encourage students to take the unit quiz to test their knowledge of echinoderms and animal classification.
