A Start with Science book about moving and rolling.
One day Oscar sees a ball in the grass. "Try pushing it!" says Cricket. Oscar learns that the ball rolls slowly in grass and faster on a path, until it bounces off a tree and changes direction. Some things need a push to move, and others use their muscles to move themselves — and to move plenty of other things, too.
Back matter includes an index and supplemental activities.
Geoff Waring has worked as a graphic designer and is the illustrator of Black Meets White by Justine Fontes. He says that the Oscar books are based on his own cat. He lives in London.
