All living things are connected in an interdependent web of life and must adapt to the environment and each other in order to thrive. This series explores delicate balances and careful connections from the cellular level all the way up to complex organisms. It is an excellent core collection that uncovers the structures and function of living things, how they adapt to their environment, and how they are grouped and classified. A special feature is included in each book, which is an activity panel. This panel introduces students to the practice of interpreting and presenting research findings, which will inspire the inner scientist in all readers.
