Why has the scientific method been important to natural science since the 17th century?

• It provides a structured way to observe, measure, experiment, and modify hypotheses.

• It encourages scientists to avoid testing their ideas.

• It focuses only on memorizing facts.

• It discourages the use of evidence in research.

• A stable subatomic particle with a charge of negative electricity.

• A method of procedure involving observation and experimentation.

What is a compound?

• A thing that is composed of two or more separate elements; a mixture.
