Explore the World of Science

At Trafalgar, our Science & Technology program guides students from foundational scientific concepts in Secondary I through specialized pathways in Secondary V. Students engage with the living world, material and technological worlds, Earth, and space, building skills in problem-solving, experimentation, and real-world application. Whether you’re curious about ecology or aiming for advanced physics and chemistry, our program supports your journey.

Connecting Science and Innovation through the CoLab

At Trafalgar, our Science program is deeply connected with the CoLab, an innovative, collaborative space where students bring scientific concepts to life through hands-on projects and real-world problem solving. CoLab encourages creativity, teamwork, and applied learning, complementing classroom science by letting students experiment, design, and innovate beyond traditional labs. Together, Science and the CoLab prepare students to think critically and tackle challenges with curiosity and confidence.
