Teacher's field guide

What Students Need to Do: Students plan a fair investigation with clear variables, measurements, and procedures. They run several trials, then have another group follow the same procedure and compare the data sets.
What Mastery Looks Like: A student writes a procedure another group can follow, controls variables, and records data from several trials. The student compares results across trials and groups before judging whether the findings are dependable.
Common Misconceptions: Students often confuse repeated trials with replication. Repeated trials use the same setup and team, while replication requires another group to conduct the study independently.
How to Assess It: Exit ticket: A team tests one paper airplane five times, while a second team follows the same procedure with a new airplane. Label the repeated trials and the replication, then name one procedure detail that must be stated.
