models

1. what are scientific models?
2. how/why are scientific models used?
3. what are some advantages of using models?
4. what are some disadvantages/limitations of using models?
5. true or false (circle one): no models are perfect.
6. true or false (circle one): once a model is made, it should never be changed.

Explanation:

1. Scientific models are simplified representations of real - world systems, phenomena or processes used to study, understand and make predictions.
2. They are used to visualize complex ideas, make predictions about future events, test hypotheses without real - world risks, and aid in communication among scientists.
3. Advantages include allowing for controlled experiments, providing a way to understand complex systems, and facilitating predictions.
4. Disadvantages/limitations are that they are simplifications and may not fully represent reality, and assumptions made in creating them can lead to inaccuracies.
5. No models are perfect as they are simplifications and approximations of reality, so True.
6. Models should be updated as new data and knowledge become available, so False.

Answer:

1. Simplified representations of real - world systems, phenomena or processes for study and prediction.
2. To visualize, predict, test hypotheses and communicate.
3. Allow controlled experiments, understand complex systems, facilitate predictions.
4. Are simplifications, may have inaccuracies due to assumptions.
5. True
6. False
