Matt is in a big shop with his mom. They want to go up to the second floor. They use a machine to go up to the second floor. What machine do they use?

There are machines everywhere, and they do lots of different jobs. The computer or smart-phone you are using is a machine. There are machines in our homes and our places of work. In our houses they help to do the washing and the cleaning. There are machines in factories to help make things. Robots are machines. Engineers design, build and look after machines.
