Petrochemicals are used as fuels, to make nylon and polyester fibres and to make other polymers which are manufactured into plastic products. The products of chemistry, such as medicines, fertilizers, and pesticides allow us to live better and longer lives. However, chemicals may affect the environment and enter the food chain. An understanding of chemical principles will enable students to weigh the risks and benefits of issues in chemistry. Chemistry is a necessary course for many areas of study such as medicine, dentistry, pharmacy, engineering, and other sciences.
Chemistry is an experimental science, involving both quantitative and qualitative observations.
Experiments and demonstrations are a key part of the course.
