What This Standard Means

What Students Need to Do

Students notice details and use them to ask clear questions that can be answered with evidence. They also describe a problem by stating what needs to change or be solved.

What Mastery Looks Like

Given a picture, short text, model, or class investigation, a student can ask a relevant question tied to specific evidence. The student can state a clear problem without jumping straight to a solution.

Common Misconceptions

Students may ask opinion questions, write questions that are too broad, or add details they did not observe. They may describe a solution instead of naming the problem that needs solving.

How to Assess It

Show a picture of an ice cube melting on a desk. Ask students to write one observation, one question they could investigate, and one problem they could solve.

Ways to Teach It

  1. Give pairs two paper towel brands, droppers, and water; students observe absorption, ask an investigable question, and define a spill-cleanup problem.

  2. Show a photo of a wilted plant and ask, “What do you notice, what do you wonder, and what problem needs solving?”

  3. Use cards with observations, questions, problems, and solutions; teams sort them, then revise one weak question or problem statement.

  4. Inspect the classroom for wasted water, scattered supplies, or glare, then have students define one problem without proposing a solution.
