Scientists are very intelligent, they are not so foolish that they will not make a model.
The scientists make model because, they have to plan their experiment.
And also for making the people understand more easily.
We too make models in our school in the Science Fair.
Why don't we just say the model!!!!!!!!!!!
It is because we have to demonstrate our science project by making a model.
And by this way we make the other people understand more nicely and easily.
