Below are sample questions representative of the exercises included on this worksheet and related 5.56 Write a Persuasive Explanation of Star Brightness skill assessments:

Problem 1Difficulty: Mastery

Context: A claim about star brightness needs evidence. Which statement best connects distance and apparent brightness?

AA science explanation should use opinion instead of evidence.

BDistance does not affect how bright a light source appears.

CThe brightest-looking star must always be the largest star.

DMeasurements or model observations should support the claim, not opinion alone.

Solution & Explanation:Apparent brightness is how bright a star looks from Earth. Distance strongly affects apparent brightness because light spreads out as it travels; strong explanations use claim, evidence, and reasoning.

Problem 2Difficulty: Mastery

Context: A distant supergiant and the Sun are compared. Which statement best connects distance and apparent brightness?

AA science explanation should use opinion instead of evidence.

BDistance does not affect how bright a light source appears.

CThe supergiant may be more luminous, but the Sun appears brighter to us because it is much closer.

DThe brightest-looking star must always be the largest star.

Problem 3Difficulty: Mastery

Context: Students compare apparent brightness and actual brightness. Which statement best connects distance and apparent brightness?

AA science explanation should use opinion instead of evidence.

BApparent brightness is how bright a star looks from Earth; actual brightness is how much light it gives off.

CDistance does not affect how bright a light source appears.

DThe brightest-looking star must always be the largest star.
