Mollusks and Their Ecosystem Roles

Miss Pam from Little Science Lab at Imagine Children's Museum introduces a lesson on seashells and mollusks. She recaps the previous lesson on seashell identification and introduces the concept of mollusks living inside shells. The lesson covers the protective nature of shells, the characteristics of mollusks, and their role in the ocean ecosystem. The session concludes with a creative project where students make a beach picture using sandpaper to simulate sand texture.
