Fundamentals of Science
R/502/5536 BTEC National 10
Guided learning hours: 60
Aim and purpose
The aim of this unit is to enable learners to develop the practical techniques necessary to pursue a career as a laboratory technician. Learners will investigate the quantities necessary in chemical reactions, the structure and functions of cells, the calorific value of different fuels and develop skills in communicating scientific information.
Learners wishing to pursue a career in science will need a general understanding of all the main sciences, including basic practical techniques. This unit introduces learners to a number of fundamental scientific concepts in chemistry, biology and physics. Learners will develop vocational practical skills and knowledge of techniques through carrying out practical investigations. These include general skills such as handling and setting up laboratory apparatus; carrying out risk analysis; safely following laboratory procedures and processes; recording and analysing data; and communication skills in recording and using information. Equipment and apparatus for more specific uses will include volumetric equipment, microscopes and simple calorimeters. The unit also concentrates on the important aspect of communicating scientific information using the correct terminology. Learners will have the opportunity to present their own information using a variety of formats and to consider the way that information is presented within a professional journal. Successful completion of this unit should develop learners underlying skills in simulating work carried out by science technicians in order to enable them to work effectively in industry and in analytical services.
On completion of this unit a learner should:
