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.

Pick the TWO reasons why we use models

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

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

• they are too large to easily study 
• they are too complicated to study
