This remarkable picture book explores scientific concepts (gravity, magnetism, electricity, friction, etc.) through the story of the relationship between a child and a puppy. Acclaimed author Lisa Westberg Peters's poems convey concepts in a way that children will remember--often with humor. Who could forget the various phases when they're presented in the form of a dog--solid when eating dinner, liquid when pouring herself into her basket, and gas when leaping erratically after a fly? Serge Bloch's whimsical illustrations extend the humor--and the love--in this tale of a child, a dog, and the energy that abounds in their world.

Extensive notes at the end of the book define and explain the physics subjects included in the poems.
