The science department integrates studies in various disciplines in sciences – chemistry, physics, biology, environmental science, and earth and space science. The department’s courses are centered on the idea that science is a quest to understand the natural and human-designed world. In addition to understanding the basic concepts of science, the science program aims to foster the development of scientific literacy by providing students with the opportunity to acquire the skills and strategies for scientific investigation. Of equal importance is the goal of relating science to technology, society and the environment, in order to make the curriculum relevant to students.

Science education at TCS involves discoveries, questions, interpretations, applications and implications. Laboratory investigations, hands-on activities and demonstrations, and research-based learning and presenting form an integral part of our science courses. Such learning opportunities are designed to arouse the curiosity of the students and to afford them opportunities to discover ideas and concepts for themselves.

Students acquire the basic knowledge and learn the skills necessary to function in, and contribute to, our modern-day society. Critical thinking and problem solving are actively encouraged to prepare the students for the rapidly changing and increasingly technologically complex world. The science department is committed integrating various types of technology as a tool for inquiry and discovery learning.
