Scientific modelling

Scientific modelling is like a game. Scientists use it to figure out how things might work. They get a picture in their head of how something works, then they make a "model" which is like a pretend version of it. The model can be anything from a simple drawing on a piece of paper, a computer program, or even a full-scale laboratory experiment! Scientists can use the model to try out different ideas and see what might happen if their ideas are correct.
