Young children are wide eyed and curious about the world around them. They are eager to understand how things work. Like scientists they observe, touch and manipulate objects. They formulate ideas and hypotheses and test their theories in processes of exploration and discovery. In this series of Play School we explore machines. Machines are devices designed to make work easier. We look at machines in the home, machines we see when we are out and about and simple machines that can be made from recycled and household materials. We hope this series of Play School provides lots of interesting opportunities for playing, making and finding out more about machines.
