Nature and meaning of science

“Nature and Meaning of Science” introduces Class 9 students to science as a systematic way of exploring the natural world, rather than a collection of fixed facts. Within “Exploration: Entering the World of Secondary Science,” students examine how observation, questioning, evidence, measurement, reasoning, experimentation, and communication work together to build scientific knowledge. The topic also highlights curiosity, objectivity, creativity, responsible investigation, and how explanations change when new evidence emerges. It connects science with everyday experiences and prepares learners for inquiry-based study of later concepts.
