Biology for IB students
Building upon the wide-ranging topics covered at GCSE level, students taking biology as an IB subject will study a range of core topics at both standard and higher level. Students will learn about the detailed structure of cells, the biological molecules that are essential for life, as well as genetics, which will include study of genetic engineering. Students will also cover ecology and evolution, and human health and physiology. These topics are similar to those that would be covered at A Level and give students a firm grasp of their subject.

Each student will select two optional units based around ecology and evolution. These may be different, or the same, for standard and higher level students. Higher level students will study additional material and cover topics such as DNA and proteins, and they will look further into the area of genetics. Other topics covered at higher level would include human reproduction, cellular respiration, the immune system, nerves, muscles and movement, the role of the kidney in excretion and plant science.

As you can see, this is a full and rounded course, one that ensures students gain practical knowledge and a depth of understanding that will allow them to pursue biology at university level, or enter into the world of biology related work.

Assessment
In general terms standard and higher level subjects are both studied throughout years 12 and 13. There are no examinations in Year 12 as all IB examinations take place in May of Year 13. In addition to the examinations you must complete a CAS journal, the theory of knowledge component and an extended essay. Each subject studied carries seven points and final grades are awarded according to a points system. The maximum mark is 45 points, made up of a potential seven points for each of the six subjects, plus three points that are available for the theory of knowledge and extended essay components.

In relation to biology specifically, the external assessment consists of three papers. The first is made up of multiple-choice questions. The second will carry a mix of short answer questions and extended response questions (one such paper at standard level and two at higher level), while the third paper, using short and extended answer questions, tests the options studied. Internal assessment is based around a number of investigations, involving both group and individual work, conducted during your IB course.

Enrichment activitiesThere will be many opportunities for practical enrichment activities across the two years of study. Students will particularly benefit from participation in ecology fieldwork projects at a field studies centre, and from involvement in the Group Four Project.

Beyond IB
The study of biology provides a scientific training, either as an end in itself or as a foundation for more advanced study. The subject is invaluable for those thinking of degrees in medicine, dentistry, pharmacy, ophthalmic optics, physiotherapy, sports science, biochemistry, applied biology, environmental studies and a host of other subjects. For those considering employment rather than further education many “biological” posts are available, locally this could involve employment in laboratories such as Caltech, and of course similar opportunities exist across the country.
