Below are sample questions representative of the exercises included on this worksheet and related 9.8 Models, Scale, and Model Limitations skill assessments:

Problem 1Difficulty: Mastery

A student revises a model because it does not match new data from a lab test. Which reason best justifies the revision?

AModels should be revised only to make them prettier.

BScientific models should be updated when evidence shows an assumption or output is inaccurate.

CA model that needs revision was never useful.

DNew data should be ignored if the first model was simple.

Solution & Explanation:Models are tools that improve through comparison with evidence. A mismatch with reliable data is a strong reason to revise assumptions, variables, or relationships.

Problem 2Difficulty: Mastery

Use the Earth-system model with reservoirs and boundary arrows. If the model leaves out volcanic gas emissions, which prediction is most affected?

AWhether reservoirs can be labeled in a model

BWhether a boundary can be drawn around a system

CWhether arrows can represent transfers between reservoirs

DHow gases added from Earth's interior may change atmospheric composition

Solution & Explanation:A missing source term limits predictions about that source. Volcanic gas emissions matter when modeling gases added from Earth's interior to the atmosphere.

Problem 3Difficulty: Mastery

Use the periodic-table trend model. Which evidence would best test whether the model's prediction about an unknown element is useful?

AWhether the element name is easy to pronounce

BMeasured properties of the element compared with the predicted trend

CThe font size used in the table

DThe number of colors in the classroom poster

Solution & Explanation:Model predictions should be compared with observations or measurements. Agreement with measured properties supports the trend model; disagreement suggests revision.
