Objects around us have different shapes, colours and uses. Some of the objects are found in nature while others are man-made.
Objects are made of materials. Materials are the substances used to make things. For example, wood pulp is the material from which paper is made.
Same material can be used to make different types of objects. For example, glass can be used to make bowls, bulbs, window panes etc. The same object can be made of different kinds of materials. For example, a chair is made of wood, plastic or iron. Some objects are made up of a combination of several materials. For example, a wooden knife and a plas stic knife Material can be classified as naturally occurring materials and man–made materials. Naturally occurring materials are found in nature. E.g., cotton, marble etc.

Sorting materials into groups is very important. You have to take care of the fact that not everything around you is something that you will know about. You have to know different types of categories in order to ensure that you group material according to their behaviour and their interaction with other things around them.
