Random House Oscar and the Cricket
Start with Science books introduce kids to core science concepts through engaging stories, fresh illustrations, and supplemental activities.
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.
