A. Multiple Choice QuestionsWhich of the following is a physical model?Answer: c) GlobeWhat does a lung balloon model represent?Answer: c) Breathing mechanismWhich model shows the flow of energy between organisms?Answer: b) Food web chartWhat does the formula Speed = Distance ÷ Time describe?Answer: c) Simple motionA simulation model is best used when:Answer: c) A physical prototype cannot handle all dataB. Short Answer QuestionsWhat are the five types of scientific models?Answer: Physical models, conceptual models, mathematical models, simulation models, and analogical models.Give two examples of conceptual models and explain what each represents.Answer:Food chain diagram: Represents how energy flows from one organism to another in an ecosystem.Water cycle diagram: Shows the movement of water through evaporation, condensation, precipitation, and collection.Why do scientists use simulation models instead of physical models in some cases?Answer: Scientists use simulation models when physical models are too complex, expensive, or impossible to build, allowing them to study systems and predict outcomes using computer-generated scenarios.How does an analogical model help students understand difficult science concepts?Answer: Analogical models use familiar objects or ideas to explain unfamiliar scientific concepts, making them easier to grasp by relating new information to prior knowledge.What is the purpose of using mathematical models in science?Answer: Mathematical models help scientists describe, analyze, and predict natural phenomena using equations and formulas, providing a precise and quantitative understanding of complex systems.
