Reach for this book when your child starts asking 'how' and 'why' regarding the physical world, or when they feel frustrated by things that seem too heavy or difficult to move. It is a perfect choice for the young builder who wants to master their environment through logic rather than just brute strength. Using whimsical scenarios, like trying to lift a lion or move a hippo, the book introduces the foundational concepts of simple machines. By framing physics as a series of playful challenges, Robert E. Wells transforms complex engineering into an accessible adventure. This book builds self-confidence by showing children that with the right tools and a bit of ingenuity, they can solve seemingly impossible problems. It is developmentally ideal for the transition from magical thinking to scientific inquiry, making it a staple for any early STEM library.
None. The book is entirely secular and focused on mechanical physics through a playful, non-threatening lens.

This book is best read when you have time to pause and look at the diagrams. It can be read cold, but it is enhanced if you have a few household items (like a ruler and a block for a lever) to demonstrate the concepts as you go. A parent might see their child struggling to move a heavy toy or asking 'How do people build big buildings?' and realize the child is ready to understand the 'how' behind the 'what.'
Younger children (age 4-5) will focus on the funny illustrations of animals in silly situations. Older children (age 7-8) will engage with the actual physics, noticing how the placement of a fulcrum or the number of pulleys changes the effort required.
Unlike many dry STEM books, Wells uses humor and 'outrageous' animal comparisons to make physics feel like a game rather than a lesson, bridging the gap between a picture book and a textbook.
The book presents a series of 'what if' scenarios involving large, heavy animals (lions, gorillas, hippos) to demonstrate how simple machines like levers, pulleys, and wheels work. It explains the mechanical advantage gained through these tools in a step by step, visual manner.
