See tough construction machines in action Let's go digging! Have you ever wondered how diggers make roads or buildings? Open the pages of Digger and imagine you are behind the controls of a powerful machine or on a busy building site. Watch the different stages as the site is first bulldozed, and then as the buildings begin to go up. Little ones will love to follow the action as they climb aboard the bulldozer, watch the concrete mixer in action and get ready to lift with a mobile crane! Digger brings to life all the action and excitement of the building site and supports the National Curriculum by exploring the history of these powerful digging machines.
