The primary use of scientific models is to simplify complex systems and phenomena, enabling researchers to predict outcomes and analyze interactions among various components. Models can represent physical, biological, or social processes, allowing scientists to test hypotheses and explore scenarios systematically. They help visualize relationships and dynamics, facilitating our understanding of natural systems and guiding data interpretation. By simulating different conditions, scientific models assist in identifying trends, generating forecasts, and informing policy decisions, playing a pivotal role in advancing scientific knowledge and practical applications.
