A lesson plan for Grade 5 Science
In this lesson, from Xpeditions, students will learn about and act out the functions of the salt marsh habitat. They will learn about the changing nature of salt marshes, and will imitate the actions of the plants and animals that live there in order to understand life in the salt marsh.
Students will:
- describe three different aspects or life forms of the salt marsh
- compare and contrast the low and high marsh
- explain what happens in different areas of the marsh at low and high tide
- explain the roles different organisms (or other elements) play in the salt marsh by acting out a salt marsh scene
