What This Standard Means
What Students Need to Do
- Students repeat the same investigation and compare the results. They explain why similar methods and conditions should lead to similar conclusions, even when measurements differ slightly.
What Mastery Looks Like
- Students identify a shared pattern across repeated trials and state a conclusion supported by the results. They can spot when a changed condition makes comparisons unfair.
Common Misconceptions
- Students may expect every measurement to be exactly the same. They may think one trial is enough or call an investigation repeated even when materials or steps change.
How to Assess It
- Give students ice-melting times of 8, 9, and 8 minutes from three matching trials. Ask them to write one conclusion and explain the small difference.

Ways to Teach It
Teams release the same toy car down the same ramp three times, measure each distance, and compare conclusions.
Ask students to write why two groups following the same seed-growing steps should reach similar conclusions.
Students sort investigation cards into fair repeats and changed tests, then explain each choice to a partner.
Test three pieces of the same paper towel for absorbency, then use the repeated results to recommend it for cleaning spills.
