Starting in a sandy area, we carefully dug for bristle worms (polychaetes) – catching many individuals ranging from 2 to 15+ centimetres long. Then we talked about different habitats and moved to the rocky part of the beach. There, the Sparks had a great time turning over rocks, catching crabs, and creating "crabitats" for them – with food, water, and shelter.
After safely releasing our crabby friends, we learned about about barnacles and watched them filter-feeding. Then we tried it ourselves, stuck to the ground while trying to catch bubbles.
All in all, it was a great time. Clearly we were in the right place, as the rainbow ended right where we were standing!
