- Amir tested four school items: Dark—paper No, ruler No, pencil No, glue No; Light—paper Yes, ruler Yes, pencil Yes, glue Yes. Which statement is supported by the evidence?
Answer: All items were invisible in dark but visible with light.
This question assesses the skill 1-PS4-2: Make observations to construct an evidence-based account that objects can be seen only when illuminated - recording evidence part. Evidence is information we collect from observations or tests. When we record evidence in a chart or table, we can see patterns. In this investigation, Amir tested 4 objects in two conditions: dark (no light) and light, and recording the results helps us see that EVERY object showed the same pattern. Amir observed paper, ruler, pencil, and glue in dark and in light; in the dark condition, Amir could not see ANY of the objects - recorded No for all 4 objects, but in the light condition, Amir could see ALL of the objects - recorded Yes for all 4, showing every single object needed light. The correct answer says 'All items were invisible in dark but visible with light' which accurately describes the pattern in the data: ALL objects (100%) were visible only when light was present, NONE (0%) were visible in darkness; this evidence supports the conclusion that objects need light to be seen, and the data is consistent across all objects tested. A distractor like 'Some items were visible in dark, but all were visible in light' is wrong because it claims some visible in dark when data shows zero; students might choose this if they focus on individual objects instead of overall pattern or don't understand what patterns mean in data. Help students read data tables by asking: 'What do you see in the dark column? All yes or all no?' 'What about the light column?' 'Is there a pattern?' Practice identifying patterns: if ALL objects show same result, that's strong evidence; explain that when every single thing we test shows the same result (all need light), that proves it's true for all objects, not just some; use visual: create chart with students, fill it in together, color-code (red for cannot see, green for can see) to make pattern obvious; watch for students who can read individual data points but don't synthesize pattern across all observations.
- Read Carlos's data. Which statement is supported by evidence?
Answer: All objects were not seen in dark but seen in light.
This question tests understanding of 1-PS4-2: Make observations to construct an evidence-based account that objects can be seen only when illuminated - specifically identifying which statements are supported by evidence. Evidence is information we collect from observations or tests. When we record evidence in a chart or table, we can see patterns. In this investigation, Carlos tested multiple objects in two conditions: lights off (dark) and lights on (light). Recording the results helps us see that EVERY object showed the same pattern. Carlos observed various objects including a chair with lights off and lights on. In the dark condition, Carlos could not see ANY of the objects - recorded 'not seen' for all objects. In the light condition, Carlos could see ALL of the objects - recorded 'seen' for all objects. Every single object needed light. The correct answer says "All objects were not seen in dark but seen in light" which accurately describes the pattern in the data: ALL objects (100%) were visible only when light was present, NONE (0%) were visible in darkness. This evidence supports the conclusion that objects need light to be seen. The data is consistent across all objects tested. Answer C "Only the chair was not seen when the lights were off" is wrong because it claims only one object was invisible in darkness when the data shows ALL objects were invisible without light. Students might choose this if they focus on one object instead of the overall pattern, or misunderstand that mentioning one example means 'only that one'. Help students understand evidence-based statements: "Does our data support this claim? Let's check!" Model checking each statement against the actual data. Practice with true/false: "Carlos saw NO objects in dark - true or false?" "Carlos saw ALL objects in light - true or false?" Watch for: students who can describe individual observations but struggle to identify what the complete set of observations means together.
- Read Sofia's data. Which statement matches the evidence?
Answer: All objects were not seen at night but seen in sunlight.
This question tests understanding of 1-PS4-2: Make observations to construct an evidence-based account that objects can be seen only when illuminated - specifically matching statements to evidence. Evidence is information we collect from observations or tests. When we record evidence in a chart or table, we can see patterns. In this investigation, Sofia tested yard objects in two conditions: night (no light) and morning sunlight (light). Recording the results helps us see that EVERY object showed the same pattern. Sofia observed various yard objects including a tree at night and in morning sunlight. In the dark condition, Sofia could not see ANY of the objects - recorded 'invisible' for all objects. In the light condition, Sofia could see ALL of the objects - recorded 'visible' for all objects. Every single object needed light. The correct answer says "All objects were not seen at night but seen in sunlight" which accurately describes the pattern in the data: ALL objects (100%) were visible only when light was present, NONE (0%) were visible in darkness. This evidence supports the conclusion that objects need light to be seen. The data is consistent across all objects tested. Answer B "Some yard objects were seen at night without any light" is wrong because it claims some objects were visible in darkness when the data shows zero objects were visible at night without light. Students might choose this if they think some objects might glow or be visible in darkness, or if they don't carefully read the data showing ALL objects were invisible at night. Help students connect natural light sources to the concept: "Is there light at night? Is there light in the morning from the sun?" Practice reading evidence carefully: "Does the data show ANY objects visible at night? What does 'all invisible' mean?" Create outdoor investigations to reinforce that sunlight is a light source that allows us to see objects.
- Read Marcus's table: Dark closet, flashlight OFF—pencil No, eraser No, scissors No, crayon No, glue stick No; Flashlight ON—each Yes. What did Marcus learn from the observations?

- Look at Emma's chart: Dark—ball No, book No, car No, cup No; Light—ball Yes, book Yes, car Yes, cup Yes. What pattern do you see in the data?
Answer: All objects could be seen only when there was light.
This question assesses the skill 1-PS4-2: Make observations to construct an evidence-based account that objects can be seen only when illuminated - recording evidence part. Evidence is information we collect from observations or tests. When we record evidence in a chart or table, we can see patterns.

- Keisha wrote: Box closed (dark)—doll NO, block NO, stuffed bear NO; Light in box—doll YES, block YES, bear YES. What does Keisha's data show?
Answer: All objects were seen only when light was in the box.
This question assesses the skill 1-PS4-2: Make observations to construct an evidence-based account that objects can be seen only when illuminated - recording evidence part. Evidence is information we collect from observations or tests. When we record evidence in a chart or table, we can see patterns. In this investigation, Keisha tested 3 objects in two conditions: dark (no light) and light, and recording the results helps us see that EVERY object showed the same pattern. Keisha observed a doll, block, and stuffed bear in dark and in light; in the dark condition, Keisha could not see ANY of the objects - recorded NO for all 3 objects, but in the light condition, Keisha could see ALL of the objects - recorded YES for all 3, showing every single object needed light. The correct answer says 'All objects were seen only when light was in the box' which accurately describes the pattern in the data: ALL objects (100%) were visible only when light was present, NONE (0%) were visible in darkness; this evidence supports the conclusion that objects need light to be seen, and the data is consistent across all objects tested. A distractor like 'Some objects were visible in dark, but all were visible in light' is wrong because it claims some visible in dark when data shows zero; students might choose this if they don't understand what patterns mean in data or treat observations as separate instead of showing consistent pattern. Help students read data tables by asking: 'What do you see in the dark column? All yes or all no?' 'What about the light column?' 'Is there a pattern?' Practice identifying patterns: if ALL objects show same result, that's strong evidence; explain that when every single thing we test shows the same result (all need light), that proves it's true for all objects, not just some; use visual: create chart with students, fill it in together, color-code (red for cannot see, green for can see) to make pattern obvious; watch for students who can read individual data points but don't synthesize pattern across all observations.
- Read Chen's desk table: Lamp OFF—notebook X, marker X, apple X, water bottle X; Lamp ON—each ✓. What can Chen conclude from this data?
Answer: All objects needed light to be seen on the desk.
This question assesses the skill 1-PS4-2: Make observations to construct an evidence-based account that objects can be seen only when illuminated - recording evidence part. Evidence is information we collect from observations or tests. When we record evidence in a chart or table, we can see patterns. In this investigation, Chen tested 4 objects in two conditions: dark (no light) and light, and recording the results helps us see that EVERY object showed the same pattern. Chen observed a notebook, marker, apple, and water bottle in dark and in light; in the dark condition, Chen could not see ANY of the objects - recorded X for all 4 objects, but in the light condition, Chen could see ALL of the objects - recorded ✓ for all 4, showing every single object needed light. The correct answer says 'All objects needed light to be seen on the desk' which accurately describes the pattern in the data: ALL objects (100%) were visible only when light was present, NONE (0%) were visible in darkness; this evidence supports the conclusion that objects need light to be seen, and the data is consistent across all objects tested. A distractor like 'Some objects could be seen with the lamp off' is wrong because it claims some visible in dark when data shows zero; students might choose this if they focus on individual objects instead of overall pattern or don't recognize 100% consistency. Help students read data tables by asking: 'What do you see in the dark column? All yes or all no?' 'What about the light column?' 'Is there a pattern?'

- Read Amir's chart. What does his data show?
Answer: All objects were not seen in dark but seen with light.
This question tests understanding of 1-PS4-2: Make observations to construct an evidence-based account that objects can be seen only when illuminated - specifically interpreting evidence patterns. Evidence is information we collect from observations or tests. When we record evidence in a chart or table, we can see patterns. In this investigation, Amir tested multiple objects in two conditions: dark hallway (no light) and with flashlight (light). Recording the results helps us see that EVERY object showed the same pattern. Amir observed various objects including a toy truck in the dark hallway and with flashlight. In the dark condition, Amir could not see ANY of the objects - recorded 'cannot see' for all objects. In the light condition, Amir could see ALL of the objects - recorded 'can see' for all objects. Every single object needed light. The correct answer says "All objects were not seen in dark but seen with light" which accurately describes the pattern in the data: ALL objects (100%) were visible only when light was present, NONE (0%) were visible in darkness. This evidence supports the conclusion that objects need light to be seen. The data is consistent across all objects tested. Answer C "The toy truck was the only object seen with light" is wrong because it claims only one object was visible with the flashlight when the data shows ALL objects were visible with light. Students might choose this if they remember their favorite object from the list but don't look at the complete pattern, or if they think 'mentioning the toy truck' means 'only the toy truck'. Help students read data systematically: "Let's check every single row. What do you notice?" Use finger tracking to go through each data point. Practice distinguishing between "The toy truck was seen" (true) and "ONLY the toy truck was seen" (false). Create sentence frames: "ALL objects were _____ in dark. ALL objects were _____ in light." to help students describe complete patterns.
- Look at Keisha's chart. What did she learn?
Answer: All objects were not seen in dark but seen with light.
This question tests understanding of 1-PS4-2: Make observations to construct an evidence-based account that objects can be seen only when illuminated - specifically learning from recorded evidence. Evidence is information we collect from observations or tests. When we record evidence in a chart or table, we can see patterns. In this investigation, Keisha tested multiple objects in two conditions: closed dark box (no light) and open box with light. Recording the results helps us see that EVERY object showed the same pattern. Keisha observed various objects including a stuffed bear in the closed dark box and with light. In the dark condition, Keisha could not see ANY of the objects - recorded 'X' for all objects. In the light condition, Keisha could see ALL of the objects - recorded checkmarks for all objects. Every single object needed light. The correct answer says "All objects were not seen in dark but seen with light" which accurately describes the pattern in the data: ALL objects (100%) were visible only when light was present, NONE (0%) were visible in darkness. This evidence supports the conclusion that objects need light to be seen. The data is consistent across all objects tested. Answer C "Only the stuffed bear needed light to be seen" is wrong because it mentions only one object instead of recognizing the pattern across all objects - the data shows EVERY object needed light, not just the stuffed bear. Students might choose this if they focus on familiar objects like toys instead of looking at all the data, or if they think soft objects might be different from hard objects. Help students use symbols in data tables: "What does X mean? What does a checkmark mean?" "Do you see all X's in one column and all checkmarks in another?" Practice generalizing: "If every single object we tested needed light, what can we say about ALL objects?" Use different recording methods (words, symbols, colors) to help students recognize patterns regardless of how data is recorded.
- Read Jamal's classroom notes. Objects: desk, chair, board, bookshelf. At 7am (dark) he wrote "invisible - too dark" for all. At 8am (bright) he wrote "visible - light present" for all. What evidence did Jamal collect?
Answer: All objects were invisible in dark, but visible when light was present.
This question aligns with the 1-PS4-2 standard, where students make observations to construct an evidence-based account that objects can be seen only when illuminated, focusing on the recording evidence part. Evidence is information we collect from observations or tests. When we record evidence in a chart or table, we can see patterns. In this investigation, Jamal tested four objects in two conditions: dark (no light) and light, and recording the results helps us see that EVERY object showed the same pattern. Jamal observed desk, chair, board, bookshelf in dark and in light. In the dark condition, Jamal could not see ANY of the objects - recorded "invisible - too dark" for all four objects. In the light condition, Jamal could see ALL of the objects - recorded "visible - light present" for all four. Every single object needed light. The correct answer says "All objects were invisible in dark, but visible when light was present." which accurately describes the pattern in the data: ALL objects (100%) were visible only when light was present, NONE (0%) were visible in darkness. This evidence supports the conclusion that objects need light to be seen. The data is consistent across all objects tested. A distractor like "Only the board was visible in dark, but others were not." is wrong because it mentions only one object instead of pattern across all, claiming some visibility in dark when data shows zero. Students might choose this if they focus on individual objects instead of overall pattern, don't understand what patterns mean in data, can describe observations but not identify what they mean together, don't recognize 100% consistency. Help students read data tables by asking: "What do you see in the dark column? All yes or all no?" "What about the light column?" "Is there a pattern?" Practice identifying patterns: if ALL objects show same result, that's strong evidence. Explain: When every single thing we test shows the same result (all need light), that proves it's true for all objects, not just some. Use visual: create chart with students, fill it in together, color-code (red for cannot see, green for can see) to make pattern obvious. Watch for: students who can read individual data points but don't synthesize pattern across all observations.
- Look at Maya's table. What can Maya conclude?
Answer: All objects were not seen in dark but seen in light.
This question tests understanding of 1-PS4-2: Make observations to construct an evidence-based account that objects can be seen only when illuminated - specifically drawing conclusions from data tables. Evidence is information we collect from observations or tests. When we record evidence in a chart or table, we can see patterns. In this investigation, Maya tested multiple objects in two conditions: dark (no light) and light. Recording the results helps us see that EVERY object showed the same pattern. Maya observed various objects including a spoon and fork in dark and in light. In the dark condition, Maya could not see ANY of the objects - recorded 'no' for all objects. In the light condition, Maya could see ALL of the objects - recorded 'yes' for all objects. Every single object needed light. The correct answer says "All objects were not seen in dark but seen in light" which accurately describes the pattern in the data: ALL objects (100%) were visible only when light was present, NONE (0%) were visible in darkness. This evidence supports the conclusion that objects need light to be seen. The data is consistent across all objects tested. Answer D "The fork was shiny, so it made its own light" is wrong because it shows a misconception that shiny objects can create light - shiny objects only reflect light, they cannot make their own light. Students might choose this if they confuse reflection with light production, or think metallic objects are special. Help students understand light sources vs reflectors: "Does a fork make light like a flashlight? Or does it need light to shine on it first?" Test shiny objects in complete darkness to show they don't glow. Explain: Shiny things are good at bouncing light back to our eyes, but they still need light to bounce! Watch for: students who think certain materials (shiny, white, or glowing stickers) can be seen without any light source.
- Read Jamal's table. What evidence did he collect?
Answer: All objects were not seen in dark but seen in light.
This question tests understanding of 1-PS4-2: Make observations to construct an evidence-based account that objects can be seen only when illuminated - specifically collecting evidence from observations. Evidence is information we collect from observations or tests. When we record evidence in a chart or table, we can see patterns. In this investigation, Jamal tested multiple objects in two conditions: before sunrise (dark) and after sunrise (light). Recording the results helps us see that EVERY object showed the same pattern. Jamal observed various objects including a board before and after sunrise. In the dark condition, Jamal could not see ANY of the objects - recorded 'not visible' for all objects. In the light condition, Jamal could see ALL of the objects - recorded 'visible' for all objects. Every single object needed light. The correct answer says "All objects were not seen in dark but seen in light" which accurately describes the pattern in the data: ALL objects (100%) were visible only when light was present, NONE (0%) were visible in darkness. This evidence supports the conclusion that objects need light to be seen. The data is consistent across all objects tested. Answer A "All objects were seen in dark but not seen in light" is wrong because it reverses the actual pattern - it claims objects were visible in darkness and invisible in light, which is the opposite of what the evidence shows. Students might choose this if they confuse the columns in the data table or misunderstand which condition had light. Help students connect time of day to light conditions: "Is it dark or light before the sun comes up? What happens after sunrise?" Use arrows or highlighting to show which column is which condition. Practice reading tables carefully: "Which column shows dark? Which shows light? Let's trace with our finger." Reinforce that sunrise brings light that allows us to see objects that were invisible in darkness.
- Jamal recorded: 7am dark room—desk No, chair No, board No, bookshelf No; 8am bright room—each Yes. What evidence did Jamal collect?
Answer: All objects were visible in light but not visible in dark.

- Read Marcus's table. He tested pencil, eraser, scissors, crayon, glue stick. In a dark closet with flashlight OFF, he wrote "invisible" for all. With flashlight ON, he wrote "visible" for all. What did Marcus learn from the observations?
Answer: Every object was invisible without light, but visible with light.
This question aligns with the 1-PS4-2 standard, where students make observations to construct an evidence-based account that objects can be seen only when illuminated, focusing on the recording evidence part. Evidence is information we collect from observations or tests. When we record evidence in a chart or table, we can see patterns. In this investigation, Marcus tested five objects in two conditions: dark (no light) and light, and recording the results helps us see that EVERY object showed the same pattern. Marcus observed pencil, eraser, scissors, crayon, glue stick in dark and in light. In the dark condition, Marcus could not see ANY of the objects - recorded "invisible" for all five objects. In the light condition, Marcus could see ALL of the objects - recorded "visible" for all five. Every single object needed light. The correct answer says "Every object was invisible without light, but visible with light." which accurately describes the pattern in the data: ALL objects (100%) were visible only when light was present, NONE (0%) were visible in darkness. This evidence supports the conclusion that objects need light to be seen. The data is consistent across all objects tested. A distractor like "Only the scissors were visible with the flashlight on." is wrong because it mentions only one object instead of pattern across all, ignoring the consistent results for every item. Students might choose this if they focus on individual objects instead of overall pattern, don't understand what patterns mean in data, can describe observations but not identify what they mean together, don't recognize 100% consistency. Help students read data tables by asking: "What do you see in the dark column? All yes or all no?" "What about the light column?" "Is there a pattern?"

- Look at Yuki's table. What pattern do you see?
Answer: All objects were not seen in dark but seen in light.
This question tests understanding of 1-PS4-2: Make observations to construct an evidence-based account that objects can be seen only when illuminated - specifically identifying patterns in recorded data. Evidence is information we collect from observations or tests. When we record evidence in a chart or table, we can see patterns. In this investigation, Yuki tested multiple objects in two conditions: dark (no light) and with lamp (light). Recording the results helps us see that EVERY object showed the same pattern. Yuki observed various objects including an orange and banana in dark and with lamp light. In the dark condition, Yuki could not see ANY of the objects - recorded 'invisible' for all objects. In the light condition, Yuki could see ALL of the objects - recorded 'visible' for all objects. Every single object needed light. The correct answer says "All objects were not seen in dark but seen in light" which accurately describes the pattern in the data: ALL objects (100%) were visible only when light was present, NONE (0%) were visible in darkness. This evidence supports the conclusion that objects need light to be seen. The data is consistent across all objects tested. Answer D "The banana was yellow, so it glowed in the dark" is wrong because it shows a misconception that bright-colored objects can glow or be seen without light - no objects glow on their own unless they are light sources. Students might choose this if they think bright colors like yellow are visible in darkness, or confuse bright colors with light production. Help students test this misconception: "Let's put a yellow banana in a completely dark closet. Can you see it? Why not?" Explain that colors need light to be seen - yellow things look yellow because they reflect yellow light, but without light there's nothing to reflect. Use examples: "Is the sun yellow? Does it make light? Is a banana yellow? Does it make light?" to distinguish light sources from colored objects.
- Look at Chen's table. What pattern did his data show?
Answer: All objects were not seen in dark but seen in light.
This question tests understanding of 1-PS4-2: Make observations to construct an evidence-based account that objects can be seen only when illuminated - specifically recording evidence to identify patterns. Evidence is information we collect from observations or tests. When we record evidence in a chart or table, we can see patterns. In this investigation, Chen tested multiple objects in two conditions: dark (no light) and light. Recording the results helps us see that EVERY object showed the same pattern. Chen observed various objects in dark and in light. In the dark condition, Chen could not see ANY of the objects - recorded 'cannot see' for all objects. In the light condition, Chen could see ALL of the objects - recorded 'can see' for all objects. Every single object needed light. The correct answer says "All objects were not seen in dark but seen in light" which accurately describes the pattern in the data: ALL objects (100%) were visible only when light was present, NONE (0%) were visible in darkness. This evidence supports the conclusion that objects need light to be seen. The data is consistent across all objects tested. Answer A "Some objects were seen in the dark and some in light" is wrong because it claims some objects were visible in darkness when the data shows zero objects were visible without light. Students might choose this if they misread the data table or don't understand that 'all' means every single object showed the same result. Help students read data tables by asking: "What do you see in the dark column? All yes or all no?" "What about the light column?" "Is there a pattern?" Practice identifying patterns: if ALL objects show same result, that's strong evidence. Use visual aids: create chart with students, fill it in together, color-code (red for cannot see, green for can see) to make pattern obvious.
- Look at Emma's chart. She tested four objects: red ball, blue book, yellow toy car, green cup. In dark she wrote "cannot see" for all. In light she wrote "can see" for all. What pattern do you see in the data?
Answer: All objects could not be seen in dark, but could in light.
This question aligns with the 1-PS4-2 standard, where students make observations to construct an evidence-based account that objects can be seen only when illuminated, focusing on the recording evidence part. Evidence is information we collect from observations or tests. When we record evidence in a chart or table, we can see patterns. In this investigation, Emma tested four objects in two conditions: dark (no light) and light, and recording the results helps us see that EVERY object showed the same pattern. Emma observed red ball, blue book, yellow toy car, green cup in dark and in light. In the dark condition, Emma could not see ANY of the objects - recorded "cannot see" for all four objects. In the light condition, Emma could see ALL of the objects - recorded "can see" for all four. Every single object needed light. The correct answer says "All objects could not be seen in dark, but could in light." which accurately describes the pattern in the data: ALL objects (100%) were visible only when light was present, NONE (0%) were visible in darkness. This evidence supports the conclusion that objects need light to be seen. The data is consistent across all objects tested. A distractor like "Only the red ball could be seen in light and dark." is wrong because it mentions only one object instead of pattern across all, claiming visibility in dark when data shows zero. Students might choose this if they focus on individual objects instead of overall pattern, don't understand what patterns mean in data, can describe observations but not identify what they mean together, don't recognize 100% consistency. Help students read data tables by asking: "What do you see in the dark column? All yes or all no?" "What about the light column?" "Is there a pattern?" Practice identifying patterns: if ALL objects show same result, that's strong evidence. Explain: When every single thing we test shows the same result (all need light), that proves it's true for all objects, not just some. Use visual: create chart with students, fill it in together, color-code (red for cannot see, green for can see) to make pattern obvious. Watch for: students who can read individual data points but don't synthesize pattern across all observations.
- Yuki wrote observations: Dark room—shoe No, hat No, backpack No; Room light on—shoe Yes, hat Yes, backpack Yes. What can Yuki conclude from this data?
Answer: All objects needed light to be seen in the room.
This question assesses the skill 1-PS4-2: Make observations to construct an evidence-based account that objects can be seen only when illuminated - recording evidence part. Evidence is information we collect from observations or tests. When we record evidence in a chart or table, we can see patterns. In this investigation, Yuki tested 3 objects in two conditions: dark (no light) and light, and recording the results helps us see that EVERY object showed the same pattern. Yuki observed a shoe, hat, and backpack in dark and in light; in the dark condition, Yuki could not see ANY of the objects - recorded No for all 3 objects, but in the light condition, Yuki could see ALL of the objects - recorded Yes for all 3, showing every single object needed light. The correct answer says 'All objects needed light to be seen in the room' which accurately describes the pattern in the data: ALL objects (100%) were visible only when light was present, NONE (0%) were visible in darkness; this evidence supports the conclusion that objects need light to be seen, and the data is consistent across all objects tested. A distractor like 'Some objects needed light, but others did not need light' is wrong because it claims some visible in dark when data shows zero; students might choose this if they don't recognize ALL objects showed same pattern or treat observations as separate instead of showing consistent pattern. Help students read data tables by asking: 'What do you see in the dark column? All yes or all no?' 'What about the light column?' 'Is there a pattern?' Practice identifying patterns: if ALL objects show same result, that's strong evidence; explain that when every single thing we test shows the same result (all need light), that proves it's true for all objects, not just some; use visual: create chart with students, fill it in together, color-code (red for cannot see, green for can see) to make pattern obvious; watch for students who can read individual data points but don't synthesize pattern across all observations.
- Carlos made a chart: No light—spoon No, fork No, plate No, cup No; With light—spoon Yes, fork Yes, plate Yes, cup Yes. What does Carlos's data show?
Answer: All objects could be seen only when there was light.
This question assesses the skill 1-PS4-2: Make observations to construct an evidence-based account that objects can be seen only when illuminated - recording evidence part. Evidence is information we collect from observations or tests. When we record evidence in a chart or table, we can see patterns. In this investigation, Carlos tested 4 objects in two conditions: dark (no light) and light, and recording the results helps us see that EVERY object showed the same pattern. Carlos observed a spoon, fork, plate, and cup in dark and in light; in the dark condition, Carlos could not see ANY of the objects - recorded No for all 4 objects, but in the light condition, Carlos could see ALL of the objects - recorded Yes for all 4, showing every single object needed light. The correct answer says 'All objects could be seen only when there was light' which accurately describes the pattern in the data: ALL objects (100%) were visible only when light was present, NONE (0%) were visible in darkness; this evidence supports the conclusion that objects need light to be seen, and the data is consistent across all objects tested. A distractor like 'Some objects were visible without light, but some were not' is wrong because it claims some visible in dark when data shows zero; students might choose this if they focus on individual objects instead of overall pattern or don't recognize 100% consistency. Help students read data tables by asking: 'What do you see in the dark column? All yes or all no?' 'What about the light column?' 'Is there a pattern?'
