A couple weeks ago Ani had an assignment in Calvert 7 science to build a tasty coral polyp.
She started with a plate that represents the limestone base to which the coral attach. She put some large marshmallows on the plate and scattered mini marshmallows on top of the large ones. The marshmallows represent the coral colony (the small ones being the buds). She stuck licorice strips into the marshmallows. Those represent tentacles. On top of all that she poured some chocolate sauce to represent a coating of limestone or calcium carbonate. Finally, she poured on some sprinkles. Those represent the stinging cells. After all that, the kids got to eat the portion of a coral reef Ani made!
