This question tests students' ability to collect and represent data showing daily changes in shadow length and direction (NGSS 5-ESS1-2). Shadows change predictably throughout the day due to the sun's apparent movement across the sky. As Earth rotates, the sun appears to move from east (sunrise) to highest point at noon to west (sunset). This causes shadows to be longest in early morning (sun low in east), shortest at midday (sun highest), and longest again in late afternoon (sun low in west). Shadow direction also changes: morning shadows point west (away from eastern sun), and afternoon shadows point east (away from western sun). To show these patterns, data must include multiple measurements throughout a single day, recording both time of observation and shadow characteristics (length and/or direction). Choice C is correct because it includes the essential data: multiple time points throughout a single day (showing the full daily pattern) and shadow measurements (length and/or direction) that reveal the pattern. This data allows students to observe that shadows are shortest at midday and longer in morning/evening. The representation (table, graph, or organized observations) makes the pattern visible and supports analysis of daily shadow changes. Choice A fails because it states shadows are longest at noon, which is incorrect as they are shortest then. This error is common when students don't understand that showing change requires multiple data points over time, or when they confuse daily patterns with seasonal patterns (which require months of data). Some students focus on irrelevant variables or don't recognize what measurements are needed to reveal the pattern. To help students: Conduct actual shadow investigations - have students trace or measure their own shadows or a fixed object's shadow at 3-5 times during the school day. Use a simple stick in playground as a shadow marker. Create data tables together, identifying what to record (time, shadow length, shadow direction). Graph the data and discuss the pattern. Connect to sun's movement: when is sun highest? Lowest? How does this affect shadows? Watch for: students who measure once and think they have 'data,' who record information but not systematically (different objects, inconsistent units, irregular times), or who don't understand that multiple measurements reveal patterns. Emphasize that scientists collect data systematically to reveal patterns that wouldn't be obvious from single observations.
