Sculpt a Sea Urchin!
Grade Level: 1, 2, 3, 4, 5, 6, 7, 8, K
Use the bases of discarded containers to make a plaster sea urchin sculpture. Many bases are already divided into fifths — perfect symmetry for a sea urchin “test”, or shell. Embellish dry plaster by adding dots of paint using a paintbrush handle, detail writers, or a small squeeze bottle. Create an entire colony of sea creatures for the classroom!
