Biology
National 5
Course Overview
The general aim of this course is to develop skills of scientific inquiry, investigation and analytical thinking, along with knowledge and understanding of Biology. Pupils will apply these skills when considering the applications of Biology on our lives, as well as the implications on society/the environment. This can be done by using a variety of approaches, including investigation and problem solving. Pupils will research issues, apply scientific skills and communicate information related to their findings, which will develop skills of scientific literacy.
The Course has three mandatory Units, as listed below.
These Units are designed to provide progression to the Units with similar titles at National5/Higher.

Assessment Methods
National 4
There is no final exam. The course is assessed on an ongoing basis through coursework and class assessments.
National 5
There is an Assignment (20 %) and an end of year exam (80 %), which will be externally assessed by SQA and will be graded (A-D).
Learning and Teaching Approaches
A wide range of teaching strategies are used with classes, such as practical and experimental work, direct teaching, paired and/or group work. Pupils will prepare presentations, projects and carry out structured practical investigations. Work in class is supported through the use of course plans, ICT and other media. Pupils will be involved in setting their own targets and evaluating their own as well as others progress. Pupils are expected to take responsibility for their learning at an early stage.
