B2 Keeping healthy Module summary

Maintaining a healthy lifestyle, avoiding infection, using medical treatments, and the biology behind these.

This is about the 2006 course. The 2011 modules are mostly similar. See the OCR 2011 specification.

Why keeping healthy?

Keeping healthy involves maintaining a healthy lifestyle, practising good hygiene to avoid infection, and using medical treatments when necessary. This module illustrates these principles through the contexts of preventing infectious disease and lifestyle diseases, in particular heart disease.

Immunity (Science explanation)

Students learn about the basic function of the immune system, and how vaccines use the body’s own defence system to prevent disease. They apply their knowledge and understanding of risk to this context: nothing can be completely safe, and all medical treatments carry some risk.

Drug development (Science explanation)

Antibiotics are a powerful weapon against infectious diseases. The increase in ‘superbugs’ requires the development of new antibiotics, and this module explores how new drugs are developed, including the stages of testing for safety and efficiency. Students also learn how appropriate use of antibiotics can help to reduce the prevalence of antibiotic resistance.

Heart disease (Science explanation)

Students learn about the structure and function of the heart, and how this is disrupted during a heart attack. They investigate risk factors associated with heart attacks and learn how scientists gather data through epidemiological studies and how individuals can minimize their risk from this disease.

Correlation and cause (Idea about Science)

This module explores ideas about correlation and cause in the context of factors contributing to heart disease, and the design of epidemiological studies. The context of smoking and lung cancer is used to illustrate how a correlation becomes proven as a causal relationship.

The scientific community (Idea about Science)

Peer review is of crucial importance in the development of scientific explanations. An understanding of peer review helps people to evaluate information when making personal and social decisions.

Making decisions about science and technology (Idea about Science)

Personal and social decisions require an understanding of the science involved but also knowledge and values beyond science. In this module, students consider particular ethical issues arising in modern medicine, for example the right of individual choice versus social policy, illustrated through vaccination policy.

Skills assessment

This module offers opportunity for Data Analysis skills assessment (antibiotic action, effectiveness of facial washes or disinfectants). There are often topical issues related to health claims in the media, so this module also provides an excellent opportunity for students to complete a Case Study, e.g. use of animals in medical research, an investigation of a recent health claim.

Health and safety

Specific guidance on health and safety associated with microbial practical work is given in the Guidance section of the OUP materials.

Advance preparation

Materials for the microbial practicals may need to be bought in advance.

Specification

See our guide to OCR website for the GCSE Science specification to which this module relates.
