Sciences refer to systematic fields of study that seek to understand the natural world through observation, experimentation, and analysis. They encompass various disciplines, including biology, chemistry, physics, and earth science, each focusing on different aspects of the universe and life. The scientific method is a key component of sciences, involving steps such as forming hypotheses, conducting experiments, and drawing conclusions based on data. This approach helps scientists develop theories and laws that explain natural phenomena, contributing to advancements in technology, medicine, and environmental understanding.
