What are Machines?

                 Machines are things made by human. They make our work easy. They also save our

                 time. Some machines need electricity to work and some do not. We use many machines
                 in our daily life. Some examples of machines are given below:




                 An air conditioner makes a room cool.

                                      A refrigerator keeps our food fresh. It also keeps the water cool.

                 We use a telephone or mobile phone to talk to people who are

                 far away.

                                   Imagine, a machine that doesn’t exist yet. Draw it in your notebook and
                                   write any one of its use.
