In common language, what is the word "theory" often mistakenly understood to mean?

• A proven fact.

• A scientific law.

• A guess.

• An established principle.

What is a hypothesis defined as in the scientific method?

• A confirmed scientific law.

What is the difference between an independent variable and a dependent variable in an experiment?

• The independent variable is the experimental result, while the dependent variable is the parameter being altered.

Which statement accurately describes the relationship between a scientific theory and a scientific law?

• A theory is a less certain version of a law, and can eventually become a law.
