In "Flip The Flaps: Planet Earth" by Dr Mike Goldsmith, illustrated by Nicki Palin, children zoom up through protective layers of the atmosphere from the surface to outer space, following the Earth as it makes its yearly journey around the Sun. Young explorers lift the flaps to reveal answers about everything from the inner workings of our planet and why volcanoes erupt to finding animals in the forests and in the sea. Plus, a fun spot-the-difference game suddenly appears as the artwork amazingly changes.
