What This Standard Means
What Students Need to Do
- Students plan a test that changes one factor while keeping others the same. They measure and record data to the precision of their tools, then make a graph. They use the graph to explain what happened.
What Mastery Looks Like
- A student writes steps another group can follow and names what they will change, measure, and keep the same. Their data table has units, and their graph has labeled axes and a useful scale. They support a claim with data and do not report more digits than their tools can measure.
Common Misconceptions
- Students may change cup size and starting temperature at once, then blame a cooling difference on the cup. They may copy every digit from a calculator when their thermometer reads only to tenths. They may treat one odd reading as the overall trend.
How to Assess It
- Exit ticket: Both cups start at 40.0°C. At 2, 4, and 6 minutes, lidded readings are 37.2, 34.8, and 32.9°C; open readings are 35.6, 31.9, and 29.1°C. Plot both series with labeled axes, name one factor to keep the same, and use two readings to explain whether the lid slowed cooling.

Ways to Teach It
Give pairs identical cups, warm water, a lid, a timer, and a digital thermometer; have them plan and run a controlled cooling test.
Ask: Why would changing cup size and adding a lid at the same time make the cooling graph hard to interpret?
Give pairs thermometer displays and calculated averages; have them sort correctly reported values from incorrect ones, then fix a mislabeled cooling graph.
Have students compare warm water in a travel mug and an open cup, then use their temperature graphs to choose a container.
