This chapter can be a little boring since most of the things here is in chemistry which if not properly illustrated can be a little discouraging to the students. Appropriate examples accompanied by sample of the chemicals will help the students to identify various materials. A field visit, if possible, to one of the manufacturing centers will give them a more better insight in the making of the material.
