I was picking up some books at the library a couple of weeks ago and Gravity Is a Mystery grabbed my attention. This isn’t a planned area of study for the NerdBug but hey, I love science and it looked fun. Now I am in love;). This book has the perfect balance of child friendly wording, illustrations and touching on actual full concepts. For example it gave the actual formula for Universal Gravitation, the actual explanation of the formula and then had a child like explanation. The more advanced explanation is separate from the “book” so you can avoid it if you would like. The illustrations are colorful and helpful to concept understanding. What is really cool is that Branley has written a variety of other books. So he may become the NerdFamily’s favorite author!
