Below are sample questions representative of the exercises included on this worksheet and related 8.101 Scale of the Solar System skill assessments:

Problem 1Difficulty: Mastery

Which final project best demonstrates scale properties of the solar system?

AA poster with planets in order but no scaled size or distance measurements

BA drawing that uses colors but does not explain what the scale represents

CA model with measured scaled sizes or distances, data tables, calculations, and a limitations explanation

DA list of planet names without size, distance, or model-limit evidence

Solution & Explanation:The standard emphasizes analyzing and interpreting data to determine scale properties, so the strongest project uses data, proportional models, and a clear discussion of limitations.

Problem 2Difficulty: Mastery

Use these approximate ranges: planet distances from Mercury 0.39 AU to Neptune 30.1 AU, and planet diameters from Mercury 4,880 km to Jupiter 143,000 km. Which comparison best explains why distance scale models often need very long spaces?

AThe diameter range is larger because 4,880 is less than 143,000

BBoth ranges are exactly 1 times

CDistance cannot be compared with ratios

DThe distance range is about 77 times, larger than the diameter range of about 29 times

Solution & Explanation:The distance range is about 30.1 divided by 0.39, or 77 times, while the planet diameter range is about 143,000 divided by 4,880, or 29 times.

Problem 3Difficulty: Mastery

An Earth model globe is 2 cm in diameter. Using the same diameter scale, the Sun-Earth distance would be about 235.4 meters. To the nearest meter, what distance is this? Give the answer in meters.

Solution & Explanation:A value of 235.4 meters rounds to 235 meters because the decimal part is less than 0.5.
