This wonderfully illustrated educational book, part of the award-winning A World In Motion program, teaches engineering principles to primary-age children through an imaginative and exciting story. In The Three Little Pigs' Sledding Adventure, readers will follow the three little pigs as they go out to play in the snow and ride on their sleds. Before long, the three little pigs discover that the Big Bad Wolf is out too, and if they are not careful, they could end up in big trouble. The story, while exciting and fun, presents scientific concepts and teaches the effects of height and weight on the pigs' sled and how far and fast it can go to escape the Big Bad Wolf.
