Below are sample questions representative of the exercises included on this worksheet and related 6.18 Scale of the Solar System skill assessments:

Problem 1Difficulty: Mastery
Why do scientists, teachers, and textbook authors often use more than one solar system model?
ANo single simple model can clearly show every feature at once while staying readable and truthful about scale
BEach model changes the order of the planets
CPlanet sizes are unknown
DScale models are never useful
Solution & Explanation:Different models highlight different features. One model might show distance well, while another shows relative size more clearly.
Problem 2Difficulty: Mastery
Why can a correct distance model make every planet look like a tiny dot?
ABecause the planets do not have real diameters
BBecause the enormous distances force the planet sizes to shrink so much at the same scale
CBecause planets only appear large at night
DBecause only the Sun can be shown in a model
Solution & Explanation:When the same scale is used for both distance and size, the huge orbital distances make the planet diameters extremely tiny.
Problem 3Difficulty: Mastery
A size model shows Earth as 10 millimeters wide and Mercury as 3.8 millimeters wide. About what fraction of Earth's diameter is Mercury? Give the answer as a decimal to the nearest tenth.
Solution & Explanation:Divide 3.8 by 10 to get 0.38, which rounds to 0.4 to the nearest tenth.
