Introduction

There are so many types of materials in the environment but if we take a good look around our homes, our schools, our community and the whole environment we would see that there is this material that is very hard, very strong, it does not break easily, it usually has a shiny surface, it is heavy, it is able to carry heat and electricity.

Examples of items that are made out of this material are spoons, nails, cutlasses, cooking pots etc. This material is called a metal.

However, there is another material around us that is just the opposite of metals. They break easily, they do not have a shiny surface, they do not carry heat and electricity well etc. Examples of items made out of this material is wood, plastic, paper, rubber etc. This other material is called a non-metal.
