We had a splashing good time at the Nature Center this morning diving into the playful world of North American river otters!
There is nothing quite like watching children get completely lost in creativity, storytelling, and asking lots of questions!
Today, our young naturalists explored the dynamic intersection of land and water habitats, focusing on how these semi-aquatic animals thrive right in our own backyard along the Rock River.
We paired our read-aloud of Otter Play with some fascinating local ecology lessons:
Life in Two Worlds: We compared land and aquatic animals, learning how river otters serve as the ultimate bridge between both systems. The kids discovered how otters sleep on land but have incredible underwater adaptations, like webbed feet, waterproof fur, and ears and nostrils that snap completely shut when they dive.
The Rock River Food Chain: We mapped out our local aquatic food web to understand who eats what beneath the surface. The kids tracked energy from river plants and algae to filter-feeding freshwater mussels and crayfish, up to local fish like sunfish and bluegills, and finally to the river otter, the ultimate apex predator of our river system.
Subterranean Neighbors: Tying back to our exploration of earth layers, we looked at how otters build their dens, or holts, tucked safely into the riverbanks, using the edge of the soil crust to rest after a long day of hunting.
Our explorers brought this science to life through two beautiful projects. They painted gorgeous, fluid water rings on canvas to showcase an otter's aquatic habitat and constructed 3D river otters from Lowell Park pinecones, each holding their favorite riverbed snacks.
We can’t wait for tomorrow’s lessons on bats and nocturnal animals!
