Teacher's field guide

What Students Need to Do: Students compare an observation with what they expected to happen. They point out a result that does not fit the pattern and describe it without changing or ignoring it.
What Mastery Looks Like: A student can identify the result that is different from the others. The student can explain why it seems unexpected and suggest checking the test again.
Common Misconceptions: Students may assume every result must match their prediction. They may ignore an odd result, change recorded data, or call any surprising event a mistake without checking.
How to Assess It: Show this result set: three ice cubes melted in 20 minutes, but one melted in 5 minutes. Ask, “Which result is unexpected, and what should we do next?”
