Teacher's field guide

What Students Need to Do: Students explain what happened during an investigation or how a design solves a problem. They share their thinking through speaking, writing, drawings, labels, or models.
What Mastery Looks Like: A student gives a clear claim and supports it with an observation or test result. The student can explain ideas alone and contribute useful details to a group response.
Common Misconceptions: Students may retell the steps without explaining the result. They may give an opinion without evidence or copy a classmate’s idea during group work.
How to Assess It: Ask students to draw and label one result from today’s investigation, then explain it to a partner. Check for an accurate result and one supporting observation.
