How does a scientific law differ from a scientific theory?

• A law is a summary of observations and results. A theory is an explanation of those observations and results.
• A theory is a summary of observations and results. A law is an explanation of those observations and results.
• A law is well-tested; a theory is not.
• A law is true; a theory isn't.

Identify the three types of variables in a controlled experiment.

• Controlled variable
• Responding variable
• Manipulated variable
• Time
• Temperature

If a supported hypothesis is only tested once, can it be called a theory?

• Yes, it has been shown to be true.
• Yes, it is an explanation of events.
• No, it has been shown to be true.
• No, it has not been tested enough.

A representation of an object or event that people use is called

• a model.
• a representation.
• a picture.
• an analogy.

Why do scientists make models?

• The scientists need to communicate their results with other people in a visual way.
• The scientists need to spend all the money they got for research.
• Models make it easier to understand things that might be too difficult to observe directly.
• Models make it easy for scientists to do experiments.
