Question 1

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?

  1. All objects were invisible in dark, but visible when light was present. (correct answer)
  2. Only the board was visible in dark, but others were not.
  3. Some objects were invisible in light, but visible in dark.
  4. All objects were visible at 7am because it was early.
Explanation: 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.

Question 2

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?

  1. Some objects were visible in dark, but all were visible in light.
  2. All objects were seen only when light was in the box. (correct answer)
  3. Only the block was seen when light was in the box.
  4. All objects were seen best when the box stayed closed.
Explanation: 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.

Question 3

Jamal recorded: 7am dark room—desk No, chair No, board No, bookshelf No; 8am bright room—each Yes. What evidence did Jamal collect?

  1. All objects were visible in light but not visible in dark. (correct answer)
  2. Only the board was visible in light but not visible in dark.
  3. Some objects were visible in dark, and some were not.
  4. All objects were visible in dark but not visible in light.
Explanation: 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, Jamal 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. Jamal observed a desk, chair, board, and bookshelf in dark and in light; in the dark condition, Jamal could not see ANY of the objects - recorded No for all 4 objects, but in the light condition, Jamal could see ALL of the objects - recorded Yes for all 4, showing every single object needed light. The correct answer says 'All objects were visible in light but not visible in dark' 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.

Question 4

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?

  1. All objects were invisible in dark but visible with light. (correct answer)
  2. Some objects were visible in dark, but others needed light.
  3. Only the scissors were visible when the flashlight was on.
  4. All objects were invisible with light but visible in dark.
Explanation: 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, Marcus tested 5 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 a pencil, eraser, scissors, crayon, and glue stick in dark and in light; in the dark condition, Marcus could not see ANY of the objects - recorded No for all 5 objects, but in the light condition, Marcus could see ALL of the objects - recorded Yes for all 5, showing every single object needed light. The correct answer says 'All objects 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.

Question 5

Look at Sofia's record: Night—bike No, sandbox No, tree No, fence No; Morning sunlight—bike Yes, sandbox Yes, tree Yes, fence Yes. Which statement is supported by the evidence?

  1. All objects were visible in the dark but hidden in sunlight.
  2. Only the tree could be seen in the morning sunlight.
  3. All objects could be seen with light but not in dark. (correct answer)
  4. Some objects needed light, but some did not need light.
Explanation: 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, Sofia 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. Sofia observed a bike, sandbox, tree, and fence in dark and in light; in the dark condition, Sofia could not see ANY of the objects - recorded No for all 4 objects, but in the light condition, Sofia 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 with light but not in dark' 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 some 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 can describe observations but not identify what they mean together. 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.

Question 6

Look at Sofia's yard record. She observed bike, sandbox, tree, fence. At night she recorded "cannot see" for all. In morning sunlight she recorded "can see" for all. Which statement is supported by the evidence?

  1. Some objects were seen at night, but none were seen in morning.
  2. All objects could not be seen in dark, but could in sunlight. (correct answer)
  3. Only the tree needed light, but the fence did not.
  4. Morning is better than night, even without light.
Explanation: 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.

Question 7

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?

  1. Some objects could be seen in the dark, but all in light.
  2. All objects could not be seen in dark, but could in light. (correct answer)
  3. Only the red ball could be seen in light and dark.
  4. All objects liked light better, so they looked brighter.
Explanation: 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.

Question 8

Look at Yuki's table. What pattern do you see?

  1. All objects were not seen in dark but seen in light. (correct answer)
  2. Some objects were seen in dark, and some were not.
  3. Only the orange was visible when the lamp was on.
  4. The banana was yellow, so it glowed in the dark.
Explanation: 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.

Question 9

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?

  1. Every object was invisible without light, but visible with light. (correct answer)
  2. Only the scissors were visible with the flashlight on.
  3. Some objects need light, but others can be seen in dark.
  4. All objects were visible without light, but invisible with light.
Explanation: 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.

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?" 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.

Question 10

Read Emma's chart. What can she conclude from evidence?

  1. All objects were not seen in dark but seen in light. (correct answer)
  2. Only the red ball needed light to be seen.
  3. Some objects needed light, but some did not.
  4. The objects preferred light, but they could see in dark.
Explanation: 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 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, Emma tested multiple objects in two conditions: dark (no light) and light. Recording the results helps us see that EVERY object showed the same pattern. Emma observed various objects including a red ball in dark and in light. In the dark condition, Emma could not see ANY of the objects - recorded 'no' for all objects. In the light condition, Emma 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 B "Only the red ball 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 red ball. Students might choose this if they focus on individual objects instead of overall patterns, or if they remember one specific object from the investigation but miss the bigger picture. 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?" 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. Watch for: students who can read individual data points but don't synthesize pattern across all observations.

Question 11

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?

  1. Some objects could be seen in the dark and light.
  2. All objects could be seen only when there was light. (correct answer)
  3. Only the red ball could be seen with light.
  4. All objects liked light better than the dark.
Explanation: 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, Emma 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. Emma observed a ball, book, car, and cup in dark and in light; in the dark condition, Emma could not see ANY of the objects - recorded No for all 4 objects, but in the light condition, Emma 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 could be seen in the dark and 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 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?'

Question 12

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?

  1. All items were invisible in dark but visible with light. (correct answer)
  2. Only the pencil was visible with light and invisible in dark.
  3. Some items were visible in dark, but all were visible in light.
  4. All items liked light, so they moved toward the lamp.

Question 13

Read Jamal's table. What evidence did he collect?

  1. All objects were seen in dark but not seen in light.
  2. All objects were not seen in dark but seen in light. (correct answer)
  3. Only the board was visible after sunrise.
  4. Some objects needed light, but some did not.
Explanation: 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.

Question 14

Read Sofia's data. Which statement matches the evidence?

  1. All objects were not seen at night but seen in sunlight. (correct answer)
  2. Some yard objects were seen at night without any light.
  3. The tree was the only object seen in the morning.
  4. Morning is better than night because it is earlier.
Explanation: 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.

Question 15

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?

  1. All objects needed light to be seen on the desk. (correct answer)
  2. Only the apple needed light to be seen on the desk.
  3. Some objects could be seen with the lamp off.
  4. All objects liked the lamp, so they looked brighter.
Explanation: 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?' 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.

Question 16

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?

  1. Only the spoon could be seen when the light was on.
  2. All objects could be seen only when there was light. (correct answer)
  3. Some objects were visible without light, but some were not.
  4. All objects were visible without light but not with light.

Question 17

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?

  1. All objects were visible in dark but invisible with light.
  2. Some objects needed light, but others did not need light.
  3. All objects needed light to be seen in the room. (correct answer)
  4. Only the backpack needed light to be seen in the room.
Explanation: 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.

Question 18

Maya tested three toys: Dark—doll Cannot see, blocks Cannot see, top Cannot see; Light—doll Can see, blocks Can see, top Can see. What do all the objects have in common?

  1. All objects could be seen in light but not seen in dark. (correct answer)
  2. Some objects could be seen in dark, but all in light.
  3. Only the doll could be seen in light and in dark.
  4. All objects were easy to see because they were colorful.
Explanation: 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, Maya 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. Maya observed a doll, blocks, and top in dark and in light; in the dark condition, Maya could not see ANY of the objects - recorded Cannot see for all 3 objects, but in the light condition, Maya could see ALL of the objects - recorded Can see for all 3, showing every single object needed light. The correct answer says 'All objects could be seen in light but not seen in dark' 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 in dark, but all in light' is wrong because it claims some visible in dark when data shows zero; students might choose this if they can describe observations but not identify what they mean together 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.

Question 19

Look at Marcus's table. What does his data show?

  1. All objects were not seen in dark but seen in light. (correct answer)
  2. Some objects were seen with no light in the closet.
  3. Only the scissors were visible when flashlight was on.
  4. Brighter light is always better than any light.
Explanation: 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 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, Marcus tested multiple objects in two conditions: dark closet (no light) and with flashlight (light). Recording the results helps us see that EVERY object showed the same pattern. Marcus observed various objects including scissors in the dark closet and with flashlight. In the dark condition, Marcus could not see ANY of the objects - recorded 'cannot see' for all objects. In the light condition, Marcus 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 C "Only the scissors were visible when flashlight was on" is wrong because it claims only one object was visible with light when the data shows ALL objects were visible with the flashlight. Students might choose this if they remember one specific object but don't recognize that every object showed the same pattern, or if they confuse 'mentioning one example' with 'only one was visible'. Help students read data tables systematically: "Let's check each row. Were any objects visible in the dark? Were all objects visible with light?" Practice identifying patterns: if ALL objects show same result, that's strong evidence. Use hand motions: sweep across all rows saying "all no" for dark column, "all yes" for light column to emphasize the complete pattern.

Question 20

Read Amir's chart. What does his data show?

  1. All objects were not seen in dark but seen with light. (correct answer)
  2. Some objects were seen in the dark hallway.
  3. The toy truck was the only object seen with light.
  4. The objects liked the flashlight, so they showed up.
Explanation: 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.
