Answer (1)
1. DefinitionsA. Physical models are tangible, 3D representations of objects or systems.Example: Model of the solar system or a volcano.B. Mathematical models use equations, graphs, and numbers to represent real-world situations or scientific concepts.Example: The formula for calculating speed: Speed = Distance ÷ Time.C. Conceptual models are ideas or visual diagrams that help explain how something works.Example: The water cycle diagram or food chain chart.2. A scientific model is a representation (physical, mathematical, or conceptual) used to explain, predict, or understand scientific phenomena. It simplifies complex systems to make them easier to study.3. Benefits & Disadvantages of Using Scientific ModelsBenefitsHelps visualize things that are hard to observe directly (e.g., atoms, solar system).Makes experiments safer and easier.Allows predictions and testing of ideas.Aids in learning and communication.DisadvantagesNot always accurate — may oversimplify the real situation.Can be misunderstood or misused.Needs regular updates when new discoveries happen.
