Tips for science questions
Science quizzes reward a few core ideas more than long lists of facts: what cells, atoms and forces are, how energy moves, and a handful of famous numbers such as the speed of light or the boiling point of water. When you learn a fact, learn the reason behind it, because a question may approach the same idea from a different angle.
