Sal is studying the solar system. He makes a physical model using different-sized foam balls to represent the planets. Which best describes why a physical model is a useful tool for studying the solar system?

• Solar system models can be used to study a system that is too big to study directly.

• A model of the solar system eliminates the need for scientists to study the solar system directly.

• A model of the solar system provides an exact replica of the actual solar system, so scientists can experience what each planet is like.

• A model of the solar system can provide more data about the solar system than direct observations.

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

Scientific models are

• Representations of objects or processes that are not easily observable

• Fashion models who are also scientists

• Testable ideas or explanations that lead to scientific invstigation

• Dependent upon the dependent variable

Pick the reasons why we use models

• Models are expensive

• Models help you understand complex systems

• Models are used when systems are too expensive or impossible to use

What is the advantage of creating a model of a dinosaur?

• they are too large to easily study 

• they are too complicated to study

• Real dinosaurs cannot be studied because they are extinct

• The model is safer to work with. 

True or False--A model can never be revised.

• true

• false
