The unit is split into three sections, each worth 30 marks:

· Section A – Biology

· Section B – Chemistry

· Section C – Physics.

Medical professionals need to understand the structure and workings of cells. They build on this knowledge to understand how the body stays healthy as well as the symptoms and causes of some diseases. This allows them to diagnose and treat illnesses. The study of bacterial, prokaryotic, cells gives an understanding of how some other diseases are caused and can be treated.

Scientists and technicians working in the chemical industry need to have an understanding of atoms and electronic structure. This allows them to predict how chemical substances will react in the production of a wide range of products - anything from fertilisers in the farming industry to fragrances in the perfume industry. Metals play an important role in the construction industry, in providing the structure to buildings, as well as in electrical wiring and the production of decorative features. So, understanding the chemical and physical properties of metals is essential when selecting appropriate building materials.

Knowledge of waves is essential in a wide range of industries and organisations. In the communication industry, scientists and technicians apply their knowledge of the electromagnetic spectrum when designing mobile phone and satellite communication, and fibre optics are used to transmit telephone and television signals. Fibre optics are also used in diagnostic tools in medicine.

This unit introduces you to standard laboratory equipment and techniques, including titration, colorimetry, calorimetry, chromatography, calibration procedures and laboratory safety.

You will become proficient in the quantitative analytical techniques of titration and colorimetry, including learning to calculate the concentration of solutions. You will use measurement of temperature to study cooling curves and be introduced to paper-and thin-layer chromatography (TLC). You will also have the opportunity to calibrate equipment.

While you develop your practical competence, the discussion and analysis of group results will allow you to understand your progress in relation to that of others and also to gain an understanding of the reliability, repeatability and reproducibility of various procedures and techniques. You will be encouraged to be aware of the safety aspects of given laboratory procedures and techniques.

The assessment task will assess learners’ ability to plan, record, process, analyse and evaluate scientific findings, using primary and secondary information/data.

In order to complete the written task, learners will need to obtain results/observations from a practical investigation.

A task brief (part A) will be released by Pearson two weeks prior to the supervised assessment period. The task brief will allow learners to complete the practical investigation and obtain results required to complete the written task booklet, in one sitting lasting 1 hour 30 minutes, under supervised conditions.

In this unit, you will focus on three body systems: musculoskeletal, lymphatic and digestive. You will examine each of the systems as a functioning unit, identifying their structure and function. By exploring the anatomy of these systems, through experimentation and use of simulations, you will develop your knowledge and understanding of their role in the human body.
