 There's story time. That sits on a leaf and nibbles the flower. Painting outside. Bunny time and grasshoppers. And singing. Tree, root, soil, and nematodes too. But these two to six-year-olds sing about things like mycelium and nematodes. And their preschool takes place entirely outside near a wetland in Denver. It's one of about 45 outdoor preschools in the state. They're currently operating with a licensing exemption.
