At Work (Library Binding) (ISBN-13: 9781914087523)

Digging and drilling, lifting and mixing; machines at work do so many different things!

Look around and discover the different machines used to help us get job done. Discover machines used at a construction site, on a farm, at the car garage, and so much more. Look at how a crane moves, or how a concrete mixer mixes. How does a combine harvester work and what does a potato planter look like?

Bright, illustrated scenes show different machines in action, while simple, informative text explains how they work. Perfect for little engineers who like to see what machines do and how they work.
