What This Standard Means

What Students Need to Do

Students read science and technical passages closely, then make claims or reasonable inferences about the ideas, processes, or results. They use exact details and explain how those details support their thinking.

What Mastery Looks Like

Students make a clear claim or inference about a science or technical passage. They select the strongest relevant detail and explain the link between that detail and their reasoning.

Common Misconceptions

Students may copy a sentence without explaining how it supports their analysis. They may choose a related fact but overlook precise words, measurements, conditions, or steps that directly prove the point.

How to Assess It

Give students a short lab procedure and ask: “What caused the result? Use one exact detail from the procedure and explain how it supports your answer.”

Ways to Teach It

  1. Give pairs a printed experiment description, highlighters, and claim cards, then have them mark the strongest supporting detail for each claim.

  2. Ask students to write: “Which detail best explains the process, and why is it stronger than another detail?”

  3. Play Evidence Match by having teams pair analysis cards with supporting quotations, then defend each match in one sentence.

  4. Compare two appliance instruction sheets and identify which specific warning details best explain how to avoid damage or injury.
