This question tests the 1st grade skill of describing when stars can be seen in the sky - at night versus during the day (1-ESS1-1: Use observations of stars to describe patterns that can be predicted). Stars are visible in the sky at nighttime when it is dark, but they are not visible during the daytime when the sky is bright and sunny. This pattern is predictable and happens every day: when the sun goes down and it gets dark (nighttime), we can see many stars in the sky; when the sun comes up and it gets bright (daytime), we cannot see stars anymore. The stars are always there, but the bright sunlight during the day makes them impossible to see, while the dark night sky lets us see their light. In this observation, Chen looks out at bedtime with a dark sky and many stars, and in the morning with a bright sky and no stars. The observation clearly shows stars visible at bedtime in the dark but not in the morning light. Choice A is correct because it accurately states stars are visible at night but not visible in daytime. This matches the observations that Chen saw stars in the dark sky at bedtime but not in the bright morning sky. Choice B reflects daytime visibility claim. This error typically occurs when students confuse different sky objects (moon/stars/sun), don't yet distinguish what's visible vs what exists, think bright sky might show stars better, haven't observed pattern multiple times, confuse conditions for visibility. To help students understand: Observe and draw the sky at daytime and nighttime; look for stars at nighttime (with adult) and note you cannot see them during day; discuss how both skies are 'real' but show different things; use picture comparisons; keep a simple chart for several days marking 'day: no stars visible, night: many stars visible.' Watch for: students who think stars don't exist during the day (they're there, just not visible), who expect to see stars during daytime if they look hard enough, who confuse stars with other sky objects like moon, or who think pattern is random rather than predictable every day/night.

In this camping trip story, Amir sees many stars at night but no stars the next morning. The observation clearly shows stars visible during the night but not in the morning light. Choice B is correct because it accurately states you can see stars at night, but not in daytime. This matches the observations that Amir saw stars at night on the camping trip but none in the morning. Choice A reflects daytime visibility claim.

In this sky journal, Carlos's night pages show many stars and day pages show no stars. The observation clearly shows a pattern of stars on night pages but none on day pages. Choice A is correct because it accurately states stars are visible at night and not visible in daytime. This matches the observations that the journal shows stars at night but not in daytime. Choice B reflects visibility reversal.

In this observation, Jamal notices many tiny lights at night but none during the day, showing a pattern of stars appearing in the dark night sky. The observation clearly shows tiny lights visible at night but not in daytime. Choice C is correct because it accurately states stars are visible at night, and not visible in daytime. This matches the observations that Jamal saw tiny lights at night but none during the day. Choice A reflects visibility reversal.

In this observation, every night Emma sees many stars and every day she sees none. The observation clearly shows a daily pattern of stars visible at night but not in daytime. Choice A is correct because it accurately states stars are visible at night, and not visible in daytime. This matches the observations that Emma saw stars every night but none every day.

In this daily observation, Yuki looks at the same sky each day with bright daytime showing no stars and dark nighttime showing many stars. The observation clearly shows a consistent pattern of stars in dark nighttime but not in bright daytime every day. Choice B is correct because it accurately states stars are visible at night but not in daytime. This matches the observations that Yuki saw no stars in bright daytime but many in dark nighttime every day. Choice A reflects visibility reversal.

In this observation, Keisha sees a sunny sky with the sun in daytime and no stars, but a dark sky with many stars at night. The observation clearly shows stars visible in the dark night but not in the sunny daytime. Choice C is correct because it accurately states stars can be seen at night when it is dark.
