Science in Key Stage 4

Students study all three subjects separately but teachers ensure that constant links are made between the three areas.

In each of the three Sciences students are encouraged to appreciate the importance to scientific methods of accurate experimental work and reporting. They are trained to form hypotheses, design experiments to test them and develop a logical approach to problem solving in a wider context.

Physics is regarded by many people as the most basic and fundamental of the three sciences. The relationship between matter and energy may sound highly theoretical but, at all times during the course, students are continually referred to the application of physics principles to everyday life.

The Chemistry course aims at developing in students an understanding of the widespread importance of chemistry and the way materials are used in the world. Students are encouraged to appreciate how the work of the chemist has social, industrial, technological, environmental and economic consequences for the community: in both positive and negative ways.

Through their study of Biology students are encouraged to develop an enjoyment of, and interest in, the study of living organisms. They are taught to evaluate, in terms of their biological knowledge and understanding, the benefits and drawbacks of scientific and technological developments, including those related to social, environmental and economic issues.


In the IGCSE assessment programme, students are entered for examinations as follows.

EITHER: Separate Sciences

Three independent examinations: one in Physics; one in Chemistry; one in Biology. These students will, on successful completion, be awarded three IGCSE grades from A* to G.

Double Award

Three linked examinations: one in physics; one in chemistry; one in biology. The material covered is about two thirds of the material of examined in the separate sciences papers. Successful students are awarded two IGCSE grades.

IGCSE Science Examinations

Biology, chemistry and physics all have the same examination structure.

Assessment is by written examination only. There is no course work and all papers are untiered.

There are two externally assessed written papers.

Paper 1

Duration is 2 hours and the total number of marks is 120 and carries 66.6% of the total marks

Paper 2

Duration is 1 hour and the total number of marks is 60 and carries 33.3% of the total marks

Assessment Objectives

Knowledge and Understanding 50%
Application, analysis and evaluation 30%
Investigative skills 20%

Successful candidates are awarded one IGCSE
