The lesson plan is for a 6th grade class taught by Estela Braun. The plan involves teaching students about wild animals and their habitats. It includes 5 activities to reinforce the differences between vertebrates and invertebrates. Students will classify animals, complete sentences with "vertebrates" or "invertebrates", listen to descriptions and match animals to images, read about animals and habitats and fill in blanks, and color code animals as vertebrates or invertebrates. For homework, students are asked to bring images of endangered animals from Argentina.
