What This Standard Means
What Students Need to Do
- Students follow another person's written procedure and compare the evidence they collect. They explain why similar results from repeated investigations make a finding more trustworthy.
What Mastery Looks Like
- Students can write clear steps that a classmate can repeat using the same materials and conditions. They can identify whether repeated results support a claim and discuss reasonable differences in data.
Common Misconceptions
- Students may think repeated investigations must produce identical measurements. They may also think one successful trial proves a claim, or that changing materials and steps still counts as a fair repeat.
How to Assess It
- Give students two sets of results from groups following the same procedure. Ask, “Do these results support the same claim, and what evidence explains your answer?”

Ways to Teach It
Groups build paper helicopters from one written procedure, time three drops, then exchange procedures and compare another group’s results.
Ask students to write why one plant-growth trial is not enough evidence, then share which conditions another investigator must keep the same.
Play Replication Sort by having teams classify scenario cards as fair repeats, changed investigations, or unclear procedures.
Compare repeated home weather measurements with official records, then discuss why using the same time, place, and tool matters.
