Branch out! Discover the importance of trees with Andy Hirsch in this volume of Science Comics, the action-packed nonfiction graphic novel series for middle-grade readers!

Starting with the seed's germination, we learn about each stage until the tree's maturation, different types of trees, and the roles trees take on in our ecosystem. Each volume of Science Comics offers a complete introduction to a particular topic. Whether you're a fourth grader doing a natural science unit at school or a thirty-year-old with a secret passion for airplanes, these books are for you!
