They learned about insects, rocks, streams, birds, snakes, turtles, animal adaptations, water, conservation, and many other environmental topics. All of the learning activities were hands-on: they hiked, found rocks and minerals, and walked in the streams they were learning about; they touched insects, snakes, turtles and birds.
