Wood has been used throughout history to build things so must be the most important material there is, right? But in this comic book-style book, other materials have something to say about that--including paper, concrete, and plastic. Each material is a silly illustrated character making the case for why they are the one that matters most! The book reaches a conclusion, but readers can evaluate it and form their own opinion. The main content supports science curricula as well as knowledge building, a key component of the science of reading.
