What does a simulation do?

• It uses models to imitate the function, behavior, or process the models represent.

• It carries on an experiment.

• It gives you ideas on how to use models.

• It imitates a real object. It's a different name for model.

Why is a model needed to test your answer to question 7? Choose the answer which is not correct.

• It allows good ideas to be separated from the ideas that will never be developed.

• It allows for money and time to be saved.

• It allows for new ideas to sprout from the scientists' brains.

Choose one of the following investigations and explain why, according to your answers to questions 7 and 8, models should be used instead of the real object. Name your choice and explain why a model or a simulation might be useful. Be careful. One should not investigate one of the topics by using models.

a• a manned rocket to reach Mars.
b• a new type of brain surgery to remove a tumor from a very deep part of the brain.
c• an observation of how lion cubs learn to hunt from their mothers.
