Science is important for developing the skills and knowledge in order to obeserve and analyse the physical and natural world around us.
Within the realm of Science, students are provided with the opportunity to select one course, or a combination of courses, as part of their timetable. At Xavier Catholic College, we offer Biology, Chemistry, Earth and Environmental Science, Investigating Science, and Physics. Along with the specific skills and content for each Science course, all courses provide opportunities for students to develop investigative depth studies that can be tailored for specific interests.
