Detailed Syllabus Overview
Introduction
Science is the study of the natural and physical world around us through a systematic process of observing, questioning, forming hypotheses, testing hypotheses through experiment, analysing evidence, and continuously revising our knowledge. It develops essential skills like curiosity, creativity, evidence-based thinking, and sound decision-making that help us lead rational and fulfilling lives. It draws knowledge from Biology, Chemistry, Physics, Earth Science, Mathematics, Computational Sciences, and sometimes Social Science and Vocational Education to offer an interdisciplinary understanding of the role of science. Together, the NEP 2020 and NCF-SE 2023 envision science classrooms that encourage curiosity, creativity, collaboration and connection with the real world.
Science Education Aims
- Scientific understanding of the natural and physical world.
- Capacities for scientific inquiry.
- Understanding the evolution of scientific knowledge.
- Interdisciplinary understanding between Science and other curricular areas.
- Understanding of the relationship between Science, Technology, and Society.
- Scientific temper and creativity.
