Detailed explanation-1: -Models are used to make predictions. They may include physical and digital models, which can be refined over time by the inclusion of new scientific knowledge. Students recognise that many scientific models have limitations and are modified as further evidence comes to light.
Detailed explanation-2: -A scientific model is a representation of real-world phenomena. Scientists, educators, and learners all use scientific models to understand the phenomenon in question better. Using models can also help scientists make predictions based on data collected about a particular phenomenon for how it may behave.
Detailed explanation-3: -A scientific model definition is a representation of an object, natural phenomenon, or system. It is created based on observations and previously known information.
Detailed explanation-4: -As additional scientific evidence is gathered, a scientific theory may be modified and ultimately rejected if it cannot be made to fit the new findings; in such circumstances, a more accurate theory is then required.
