Science BTEC


Pearson BTEC Level 3 National Extended Certificate in Applied Science

Designed for learners who are interested in learning about the sector alongside other fields of study, with a view to progressing to a wide range of higher education courses, not necessarily in applied science.

To be taken as part of a programme of study that includes other appropriate BTEC Nationals or A Levels.


BTEC Nationals require applied learning that brings together knowledge and understanding with practical and technical skills.

This is achieved through learners performing vocational tasks that encourage the development of appropriate vocational behaviours and transferable skills. Transferable skills are those such as communication, teamwork, research and analysis, which are valued in both higher education and the workplace.

This information, along with the course details below, is taken from the Edexcel specification, which can be found at the following link:

3 Science Investigation Skills synoptic external assessment      120 GLH

Learners will cover the stages involved and the skills needed in planning a scientific investigation:

how to record, interpret, draw scientific conclusions and evaluate.

As well as drawing on Unit 1 and Unit 2, these skills will be delivered through subject themes ranging from enzymes and diffusion to electrical circuits. The subject themes provide different contexts for the development of the investigative skills. In this unit you will draw on your learning from across your programme to complete assessment tasks.


8 Physiology of Human Body Systems     internal assessment                    60 GLH

Learners will focus on the physiological make up of three human body systems (musculoskeletal, lymphatic and digestive), how the systems function and what occurs during dysfunction.
