What This Standard Means

What Students Need to Do

Students figure out why someone wrote a science or technical text and what view the writer takes. They explain how that choice affects the wording and the details included.

What Mastery Looks Like

Given a lab procedure and an experiment summary, students can explain why one uses commands while the other presents measurements and careful claims. They point to a phrase or detail in each text as evidence.

Common Misconceptions

Students may confuse a writer's point of view with the use of first-person pronouns. They may spot a warning or measurement without explaining why the writer included it.

How to Assess It

Exit ticket: Read, "Wear goggles before adding vinegar; record the gas volume every 30 seconds." Explain why the writer uses commands and includes both a warning and a measurement step.

Ways to Teach It

  1. Have pairs test two paper towels with measured water, then write a lab note for scientists and an instruction card for classmates.

  2. Ask: Why does a lab report include measurements while a safety card uses commands? Write two sentences using an example from each.

  3. Give teams four cards: a procedure, a product claim, a lab report, and an explanation. Have them sort by purpose and defend one word choice.

  4. Compare a thermometer manual with an online product review; students circle safety warnings and opinions, then explain why each writer included them.
