Machine Definition

For Inquiry we defined what a machine is and the roles they play in our lives.

WALT - Define a Machine

A machine is something we use to make life easier. We are surrounded by machines that do all sorts of jobs for us like wash our clothes, transport us places and help us build shelters. Even basic tools like scissors, screwdrivers and tweezers are machines. These types of machines are called simple machines. A simple machine has one or no moving parts and can often make up parts of complicated machines.

There are six types of simple machines these are wedge, wheel and axle, inclined plane, lever, screw and pulley. Simple machines are found in every home and school. In our classroom we have scissors that are wedges and levers, hinges on our doors that are levers and screws to hold together our bookshelves. Simple machines make work faster and easier imagine trying to cut paper with just your fingers!

Overall we believe life without machines would be very difficult for example there would be no cars to help us travel, knives to help cut our food, cranes to lift building materials or axes to cut wood for fire or shelter.
