Scientific Method

Why don't scientists stop the scientific method after they make observations?

• They don't trust their own observations and want others' opinions.

• They would rather run experiments than observe the world around them.

• They want to test what they observe to make sure it is correct.

• They don't think observations are a very good place to start.
