Test This Book! features a bear scientist and a frog scientist testing how books work in a variety of exciting, dramatic experiments. What happens when readers sit on their books? Shake them? Whisper secrets to them? The results are funny, surprising, and very, very informative. Test This Book! is a great read-aloud experience, as readers are rewarded for physically interacting with the book. And they also learn a little about the scientific method--the basis of all STEM education--thanks to some helpful backmatter.
