Biology is the study of life and living things. The Senior High Biology course offered at Toowoomba Christian College presents life as created by God and gives students an opportunity to gain an appreciation of His created order.

Throughout the course, students will be required to study the structure of living organisms and their relationship with both other living and non-living components of their environment. Students will also explore, through onsite and offsite, short-term and extended practical investigations, a variety of biological concepts and processes. A dedication to commit factual details to memory and a willingness to engage in creative and critical scientific inquiry and thinking are therefore important characteristics for Biology students to possess.

Students achieving a minimum of a C in Year 10 Science will have the prerequisite knowledge for Senior High Biology.

Biology is beneficial for students considering careers including nursing, dietician, beautician, botanist, biochemist, agriculturalist, bacteriologist, laboratory worker, marine biologist, dentist and biological researcher.

Senior High Biology runs on a two-year cycle with a combined class of Year 11 and Year 11 students.
