Natural science is a branch of science that focuses on understanding the natural world through observation and experimentation. It encompasses various fields, including biology, chemistry, physics, and earth science. Natural scientists study the laws of nature, the properties of matter, and the interactions between different systems in the environment. The goal of natural science is to develop theories and models that explain natural phenomena. By using the scientific method, researchers gather data, formulate hypotheses, and conduct experiments to test their ideas. This systematic approach helps to build a body of knowledge that can be used to make predictions and solve real-world problems.
