This unit for students in grade 3 was developed by Dierdre Detjens through her 2019 Teacher-in-Residence at Cape Cod Museum of Natural History in Brewster, MA.
This unit focuses on horseshoe crabs, Limulus polyphemus. Students will understand how unique our local Cape Cod horseshoe crabs (HSCs) are. The lessons compare horseshoe crabs to other local organisms. At the end of the unit, students will create a public service announcement explaining to other Cape Codders the importance of our local horseshoe crabs.
