What This Standard Means
What Students Need to Do
- Students distinguish a scientific theory, which explains how or why phenomena occur, from a scientific law, which describes a consistent pattern. They identify examples and connect each theory to observations, experiments, or other supporting evidence.
What Mastery Looks Like
- Students correctly classify examples as theories or laws and explain their reasoning without treating one as stronger than the other. They name several theories, such as cell theory and plate tectonics, and cite supporting evidence for each.
Common Misconceptions
- Students may think a theory is an unsupported guess or that theories become laws after enough testing. They may also think laws explain why something happens, rather than describing what consistently happens.
How to Assess It
- Use this exit ticket: “Explain one difference between a theory and a law. Name two scientific theories and give one piece of evidence supporting each.”

Ways to Teach It
Have students sort theory, law, example, and evidence cards into matched groups, then defend one match to a partner.
Ask students to write a response to: “Can a scientific theory become a law? Explain using one example.”
Run an evidence-match relay where teams pair cell theory, plate tectonics, and germ theory with observation and experiment cards.
Give students a news headline using “theory” casually, then have them rewrite it using the scientific meaning and add needed evidence.
