They grow all around us, but how often do we stop and enjoy these wonderful, living giants? In this title, kids will act as plant scientists to investigate how trees grow, how they get water, food and nutrients, how they produce the oxygen we breathe and clean the air around us, how they defend themselves, and how they provide food and shelter for thousands of different animals. Readers will get to meet the tallest trees, the oldest trees, and some very unusual trees. The book includes critical thinking questions, activities and experiments, and it is supported with downloadable worksheets.
