Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe. It encompasses various disciplines, including physical sciences (like physics and chemistry), life sciences (like biology and ecology), and social sciences (like psychology and sociology). Science relies on empirical evidence obtained through observation and experimentation, and it uses the scientific method—an iterative process that involves forming hypotheses, conducting experiments, and drawing conclusions based on data. The goal of science is to enhance understanding of natural phenomena, develop new technologies, and solve practical problems, ultimately contributing to human knowledge and advancement.
