why do scientists use models

Scientists use models because they help simplify and visualize complex systems or phenomena that are difficult to observe directly. Models allow scientists to test hypotheses, conduct experiments, and make predictions in a controlled and understandable way. They also facilitate collaboration by providing a standardized representation of knowledge and can drive innovation by enabling simulations and experimentation that would be impossible or impractical in real life. Models are crucial for explaining, understanding, and predicting how things work in various scientific fields.
