An experiment is a scientific procedure used to test a hypothesis or explore a phenomenon. It involves making observations, collecting data, and analyzing results to draw conclusions. Experiments can be conducted in various fields, including biology, chemistry, and physics, and often require careful planning and control of variables to ensure accurate results. In an experiment, researchers typically manipulate one or more variables, known as independent variables, while measuring the effect on other variables, called dependent variables. This process helps scientists understand cause-and-effect relationships and can lead to new discoveries or advancements in knowledge, such as the development of new medicines or technologies.
