Fish flit through a saltwater aquarium at the main entrance of Discovery Kids Place in Silver Springs, MD. Inside, the eco-certified child-care facility has bright and airy classrooms with floor-to-ceiling windows, colorful rugs and low tables for small-group activities. Dedicated to naturalist Steve Irwin, the outdoor play park, Crikey Cove, is modeled after the Australian outback with rock outcroppings, pathways in aborigine-inspired geometric designs, a boat climbing structure and the odd python or kangaroo.
