What is Science?
Science is defined as the systematic study of the physical and natural world through observation and experimentation. It involves collecting data, forming hypotheses, testing them through experiments, and establishing theories or laws that explain natural phenomena. The section elaborates that science is not just a body of knowledge but a process that involves curiosity, questioning, and critical analysis. It distinguishes science from other forms of knowledge by its reliance on empirical evidence and reproducibility. The section also discusses the branches of science, including physics, chemistry, biology, and earth sciences, each focusing on different aspects of the natural world. It emphasizes that science is dynamic and continuously evolving as new discoveries are made and old theories are refined or replaced. The importance of scientific methods, including observation, hypothesis formulation, experimentation, and conclusion, is highlighted as the backbone of scientific progress.
