The manipulation of a model in such a way that it behaves like a real system is called:

• simulation

• manipulation

• modelling

• organization

Models can be helpful in scientific investigations because

• it may not be possible to work with the real thing

• they can be smaller and more manageable than the real thing

• they can be safer to work with than the real thing

• all of the above
