Scientists often use visual or mathematical representations to investigate items that are very large, very small, or otherwise difficult to study.  What are these visual or mathematical representations called?

• experiments
• hypotheses
• models
• 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
