Terms 1-6: Module 1 - Development of skills in practical Biology
The development of practical skills is a fundamental and integral aspect of the study of any scientific subject. These skills not only enhance learners’ understanding of the subject but also serve as a suitable preparation for the demands of studying biology at a higher level.

Hypothesis
A proposed explanation based on limited evidence which is used as a starting point for further investigation.
Independent variable
A variable or factor that does not depend on another. It is the variable that is changed in a scientific experiment.

Term 1: Module 2 - Cell structure
Biology is the study of living organisms. Every living organism is made up of one or more cells, therefore understanding the structure and function of the cell is a fundamental concept in the study of biology. Since Robert Hooke coined the phrase ‘cells’ in 1665, careful
observation using microscopes has revealed details of cell structure and ultrastructure and provided evidence to support hypotheses regarding the roles of cells and their organelles.
