Questions come before answers
Scientific work begins by defining a question clearly enough that evidence can bear on it.
Evidence has to connect to the claim
Measurements, observations and experiments are useful only when they actually test the explanation being considered.
Science is self-correcting, not instantly perfect
Results can be revised when better data, methods or models reveal weaknesses.
Science is not a list of trivia
The important skill is understanding how evidence supports an explanation and how confident we should be.
