Why do we use models to study the solar system and space?

• Because some items that we want to study are too large to see, so we create small models that represent the item we want to study.

• We can use models to create laws and improve the solar system.

• Because the solar system does not match what we know about space so we build a model to meet what we want it to look like.

• So teachers can make scholars build the models during science class.

All good models should:

• be as close to the real thing as possible

• be built only after the scientist studies the real system

• be built based on evidence collected by the scientist

• All of the above

Models help scientists:

• develop explanations

• make predictions

• communicate ideas

• all of the above

True or False: Models can ONLY be used to represent things that are too big for us to observe directly.

• True

• False

One of the first records of the stars come from:
