  Evidence is:

• anything that can be used as a weapon.

• another word for a scientific idea.

• the data collected in experiments.

• a measure of how dense different solids are.

A theory is:

• an idea that explains evidence.

• the result of an experiment.

• a chapter in a science book.

• the instructions for doing an experiment.

How do scientists test theories?

• They see if their friends agree with them.

• Theories are always correct, so scientists do not need to test them.

• They use the theory to make predictions, and do experiments to see if the predictions are correct.

• They look in a different book.
