KS4

Teaching Science in key stage 4 continues building upon and deepening scientific knowledge and the understanding of ideas developed in earlier key stages in the subject disciplines of Biology, Chemistry and Physics.

For some students, studying the sciences in key stage 4 provides the platform for more advanced studies, establishing the basis for a wide range of careers. For others, it will be their last formal study of subjects that provide the foundations for understanding the natural world and will enhance their lives in an increasingly technological society.

Science is changing our lives and is vital to the world’s future prosperity, and all students will be taught essential aspects of the knowledge, methods, processes and uses of science. They will be helped to appreciate the achievements of science in showing how the complex and diverse phenomena of the natural world can be described in terms of a few key ideas relating to the sciences which are inter-linked, and which are of universal application.
