Materials can be natural or
man-made.
Natural materials are found in
nature. They come from plants, animals, minerals and rocks. Wood, leather,
cotton, wool and sand are all natural materials.

Man-made materials are not found in
nature. They are made by people. For example, paper is made from wood, glass is
made from sand, and plastic is made from petroleum.
