The Science Department pedagogical framework aims to instil the joy of learning Science and use the scientific knowledge they acquire to guide Crestans make better decisions in life.


Science in Crest is a two-year journey with a customised modular curriculum focusing on topics that best equip Crestans with the knowledge and skills relevant to their daily lives and future careers. Students with aspirations to further their study in Science have the option of taking the subject in upper secondary.

Our Science Curriculum is designed to educate Crestans through real-life applications of scientific theories, packed with hands-on activities, and learning journeys. Even assessments are made authentic by including practical elements, on top of paper and pen tests.
