Scientist only use empirical evidence to learn about the natural world.

Scientist always try to measure things as closely as they can.

Scientist try to look at things without bias or letting their feelings or beliefs get in the way.

Scientific findings should be repeatable even if someone else is doing the experiment.

Science just discovers knowledge it is neither good nor bad.

Science attempts to uncover the truth in exact words.

If a scientific theory can describe what happens in the future it is a very good theory

Scientists will check their measuring instruments (this is called calibrating) to insure that they measure close to the true value.

When the scientist used his theory to explain the outcome of a reaction before it happened and was right she knew she had a good theory.

When scientist want to test a theory the are working on they might have others try to repeat their experiment to make sure they get the same result.

Scientist can make new pesticides and test them, but it can't help us decide if it is a good idea to use them.

The scientist made sure they followed a well know procedure for completing the research.

A scientist might have another scientist look over their data to see if they come to the same conclusion. This would help eliminate any bias he might have in his conclusion.
