Year 8 Science


In this subject, students gain an insight into the wonder and complexity of God’s creation through studies in the areas of Energy, Electricity, Chemistry and Biology.  The study of Problem Solving and the Scientific Method enables students to analyse problems and communicate findings scientifically.  Year 8 Science encourages students to use the abilities God has given them.  It extends students’ understanding of scientific concepts as well as developing their skills of scientific investigation.  The skills of critical thinking and analysis developed in science are useful in many areas of life while knowledge of God’s creation is essential to fully appreciate its intricacy.

Course Objectives

By the end of Year 8, students compare physical and chemical changes and use the particle model to explain and predict the properties and behaviours of substances. They identify different forms of energy and describe how energy transfers and transformations cause change in simple systems. They analyse the relationship between structure and function at cell, organ and body system levels. They explain how evidence has led to an improved understanding of a scientific idea and describe situations in which scientists collaborated to generate solutions to contemporary problems.

Students identify and construct questions and problems that they can investigate scientifically. They consider safety and ethics when planning investigations, including designing field or experimental methods. They identify variables to be changed, measured and controlled. Students construct representations of their data to reveal and analyse patterns and trends, and use these when justifying their conclusions. They explain how modifications to methods could improve the quality of their data and apply their own scientific knowledge and investigation findings to evaluate claims made by others. They use appropriate language and representations to communicate science ideas, methods and findings in a range of text types.
