The study is made up of four units:

Unit 1: What ideas explain the physical world?

Unit 2: What do experiments reveal about the physical world?

Unit 3: How do fields explain motion and electricity?

Unit 4: How can two contradictory models explain both light and matter?

Each unit deals with specific content contained in areas of study and is designed to enable students to achieve a set of outcomes for that unit. Each outcome is described in terms of key knowledge and key science skills.
