Who doesn't love learning about the ocean? And who wouldn't want to help create an ocean themed mural? Little learners make lobsters out of recycled egg cartons, pipe cleaners, and paint. These are then used as part of a larger 3-D ocean mural. Tip: Discuss lobster anatomy and how crustaceans are similar and/or different than other ocean life forms. You can also discuss how lobsters are similar to insects.
