Lesson Plan

A Salt Marsh Ecosystem

What a web we weave. Pupils use yarn as the primary resource to create a web depicting the intricacies of a salt marsh ecosystem. They participate in a question and answer session, which leads to an in-depth facilitated discussion about the importance of ecosystems and how daily activities influence the natural order of our environment.
