                         Visit different places and identify  the different types of machines like
                         music system, a watch, a television, a mobile phone, a refrigerator and
                         a computer. Identify the machines which need electricity to work and
                         which don't.








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