This resource covers many topics in the renewed science curriculum. Using the ancient Greek division of the world using spheres, the authors examine the atmosphere (air), pedosphere (land), biosphere (living), hydrosphere (water), cryosphere (frozen), and geosphere (subterranean). The animals, plants, and landforms that exist within each sphere are described.
