Scientific Models

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.
