In scientific terms, which of the following best defines a "model"?

A model in scientific terms is best defined as a simplified representation of reality. This is because models are created to help scientists and researchers understand complex systems or phenomena by breaking them down into more manageable parts. They often capture essential features and relationships while leaving out unnecessary details that can complicate understanding.

For example, a physical model of the solar system helps visualize the positions of planets and their orbits without detailing every aspect of their physical characteristics. Similarly, mathematical models can use equations to represent biological populations, economic systems, or climate patterns, making predictions based on fundamental principles. Ultimately, models allow scientists to simulate and predict outcomes, facilitating further investigation and learning.
