Hidden Worlds

Nature has lots of hidden wonders, from wasps' nests tucked in hollow tree trunks to ant colonies built in mounds on the ground. Join a class of kids as they walk through a big park and find wonderful things happening everywhere. The tabs help uncover it all. Does the pond look empty? Give a pull and suddenly the water teems with mussels, stickleback fish, a great diving beetle, a swimming frog, mosquito larvae, newts, and flora. Look busy beavers are building their dam; and there are the ventilation shaft, food store, living chamber, and below-the-waterline entrance. Science has never been so entertaining.
