Using models in science teaching is an effective way to help students understand complex concepts by providing a visual and tangible representation of abstract ideas. Models can range from physical replicas to computer simulations, allowing learners to explore scientific phenomena in a controlled and interactive environment. They facilitate deeper comprehension by enabling students to observe processes, make predictions, and test hypotheses without the constraints of real-world experimentation. Additionally, models encourage critical thinking and problem-solving skills, making science more accessible and engaging for learners of all ages.
