Question 1

Read Sofia's window test: glass→see outside; tissue→blurry shapes; poster board→dark; mirror→light bounced back. What did Sofia learn about materials and light?

  1. Different materials can pass, block, or reflect light. (correct answer)
  2. All materials blocked light because the Sun was bright.
  3. Poster board let all light pass through the window.
  4. Only mirrors affect light, because they are smooth.
Explanation: This question assesses the skill 1-PS4-3: Plan and conduct an investigation to determine the effect of placing objects made with different materials in the path of a beam of light - observing and recording results part. Different materials affect light in different ways. Transparent materials (like clear plastic, glass) let all light pass through - we can see through them and light shines through brightly. Translucent materials (like wax paper, tissue) let some light pass through - light is dim, shadows are light gray. Opaque materials (like cardboard, wood, thick cloth) block light completely - no light passes through, shadows are dark. Some shiny materials (mirror, foil) also reflect light back. Sofia tested 4 materials. Results showed: glass let all light through (see outside), tissue let some light through (blurry shapes), poster board blocked all light (dark), mirror reflected light (light bounced back). The pattern is clear: material type determines effect on light. 2 materials let light through, 1 blocked light, 1 reflected. The correct answer says 'Different materials can pass, block, or reflect light' which accurately describes the pattern in data. This shows understanding that materials have different properties: some are transparent (light passes through), some translucent (some light passes), some opaque (light blocked). The data clearly shows these different effects. An error type like 'All materials blocked light because the Sun was bright' is wrong because it claims all materials same when data shows different effects. Students might choose this if they don't recognize pattern across multiple observations, focus on single material not overall results, confuse material properties with light transmission, expect all materials to behave the same way, don't understand categories like transparent vs opaque. Help students analyze data by asking: 'Which materials let light through? Which blocked light? Are there groups with similar results?' Create visual sorting: picture cards of materials, sort into 'light passes' 'some light' 'light blocked' piles. Explain categories: Transparent = see through clearly, light passes. Translucent = see shapes/light but blurry, some light passes. Opaque = cannot see through, blocks light. Demonstrate: 'Can you see my hand through clear plastic? Yes - transparent. Through wax paper? A little - translucent. Through cardboard? No - opaque.' Connect to everyday: windows (transparent glass), shower curtain (translucent), walls (opaque). Watch for: students who don't recognize materials can be grouped by similar light effects, or who attribute light passing to unrelated properties like color, weight, or texture instead of transparency.

Question 2

Keisha saw: clear plastic→bright through; frosted plastic→dim through; black cloth→no light; mirror→reflected. Which materials let some light pass?

  1. Black cloth and mirror let some light pass through.
  2. Clear plastic and mirror let some light pass through.
  3. Frosted plastic let some light pass through and looked dim. (correct answer)
  4. All materials let some light pass through in the same way.
Explanation: This question assesses the skill 1-PS4-3: Plan and conduct an investigation to determine the effect of placing objects made with different materials in the path of a beam of light - observing and recording results part. Different materials affect light in different ways. Transparent materials (like clear plastic, glass) let all light pass through - we can see through them and light shines through brightly. Translucent materials (like wax paper, tissue) let some light pass through - light is dim, shadows are light gray. Opaque materials (like cardboard, wood, thick cloth) block light completely - no light passes through, shadows are dark. Some shiny materials (mirror, foil) also reflect light back. Keisha tested 4 materials. Results showed: clear plastic let all light through (bright through), frosted plastic let some light through (dim through), black cloth blocked light (no light), mirror reflected light (reflected). The pattern is clear: material type determines effect on light. 2 materials let light through, 1 blocked light, 1 reflected. The correct answer says 'Frosted plastic let some light pass through and looked dim' which accurately describes the specific observations. This shows understanding that materials have different properties: some are transparent (light passes through), some translucent (some light passes), some opaque (light blocked). The data clearly shows these different effects. An error type like 'All materials let some light pass through in the same way' is wrong because it claims all materials same when data shows different effects. Students might choose this if they don't recognize pattern across multiple observations, focus on single material not overall results, confuse material properties with light transmission, expect all materials to behave the same way, don't understand categories like transparent vs opaque.

Watch for: students who don't recognize materials can be grouped by similar light effects, or who attribute light passing to unrelated properties like color, weight, or texture instead of transparency.

Question 3

Jamal sorted materials: All through—clear glass, plastic wrap; Some through—tissue, thin paper; Not through—cardboard, dark cloth; Mirror—reflects. Which materials let light pass through?

  1. Cardboard and dark cloth let light pass through.
  2. Clear glass and plastic wrap let light pass through. (correct answer)
  3. Mirror and cardboard let light pass through.
  4. All materials let light pass through the same amount.
Explanation: This question assesses the skill 1-PS4-3: Plan and conduct an investigation to determine the effect of placing objects made with different materials in the path of a beam of light - observing and recording results part. Different materials affect light in different ways. Transparent materials (like clear plastic, glass) let all light pass through - we can see through them and light shines through brightly. Translucent materials (like wax paper, tissue) let some light pass through - light is dim, shadows are light gray. Opaque materials (like cardboard, wood, thick cloth) block light completely - no light passes through, shadows are dark. Some shiny materials (mirror, foil) also reflect light back. Jamal sorted multiple materials. Results showed: clear glass and plastic wrap let all light through, tissue and thin paper let some light through, cardboard and dark cloth blocked light, mirror reflected light. The pattern is clear: material type determines effect on light. 4 materials let light through (2 all, 2 some), 2 blocked light, 1 reflected. The correct answer says 'Clear glass and plastic wrap let light pass through' which accurately describes the correct classification of materials. This shows understanding that materials have different properties: some are transparent (light passes through), some translucent (some light passes), some opaque (light blocked). The data clearly shows these different effects. An error type like 'All materials let light pass through the same amount' is wrong because it claims all materials same when data shows different effects. Students might choose this if they don't recognize pattern across multiple observations, focus on single material not overall results, confuse material properties with light transmission, expect all materials to behave the same way, don't understand categories like transparent vs opaque. Help students analyze data by asking: 'Which materials let light through? Which blocked light? Are there groups with similar results?' Create visual sorting: picture cards of materials, sort into 'light passes' 'some light' 'light blocked' piles. Explain categories: Transparent = see through clearly, light passes. Translucent = see shapes/light but blurry, some light passes. Opaque = cannot see through, blocks light. Demonstrate: 'Can you see my hand through clear plastic? Yes - transparent. Through wax paper? A little - translucent. Through cardboard? No - opaque.' Connect to everyday: windows (transparent glass), shower curtain (translucent), walls (opaque). Watch for: students who don't recognize materials can be grouped by similar light effects, or who attribute light passing to unrelated properties like color, weight, or texture instead of transparency.

Question 4

Keisha saw: clear plastic=bright, wax paper=dim, black cloth=blocked, foil=reflected. Which material reflected light?

  1. Wax paper reflected light back as a shiny spot.
  2. Clear plastic reflected light back as a shiny spot.
  3. Aluminum foil reflected light back as a shiny spot. (correct answer)
  4. Black cloth reflected light back as a shiny spot.
Explanation: This question assesses the skill 1-PS4-3, which involves planning and conducting an investigation to determine the effect of placing objects made with different materials in the path of a beam of light, focusing on observing and recording results. Different materials affect light in different ways: transparent materials like clear plastic or glass let all light pass through, allowing us to see through them clearly with bright light; translucent materials like wax paper or tissue let some light pass through, making the light dim and shadows light gray; opaque materials like cardboard or wood block light completely, creating dark shadows, while some shiny materials like mirrors or foil reflect light back. Keisha tested four materials, and the results showed: clear plastic let light through brightly, wax paper dimly, black cloth blocked it, and foil reflected it as a shiny spot. The pattern is clear: material type determines the effect on light, with one letting all through, one some, one blocking, and one reflecting. The correct answer says 'Aluminum foil reflected light back as a shiny spot' which accurately describes the specific observation for the reflective material, showing understanding that shiny materials bounce light back, as the data clearly identifies foil's effect. A distractor like 'Black cloth reflected light back as a shiny spot' is wrong because it attributes reflection to an opaque material that blocked light, not reflected; students might choose this if they confuse blocking with reflecting or focus on color like black instead of shininess. To help students, ask: 'Which materials let light through? Which blocked light? Are there groups with similar results?' Create visual sorting with picture cards of materials into 'light passes,' 'some light,' 'light blocked' piles, explain categories like transparent for clear views, translucent for blurry light, opaque for no light, demonstrate with hand visibility through examples, connect to everyday items like windows or walls, and watch for students who attribute reflection to non-shiny materials.

Question 5

Read Sofia's window test: glass=all, tissue=some, poster board=blocked, mirror=reflected. What did Sofia learn?

  1. Different materials changed light in different ways. (correct answer)
  2. All materials blocked light, so the room stayed dark.
  3. Poster board let all light pass through like glass.
  4. Only mirrors can be used near windows in sunlight.
Explanation: This question assesses the skill 1-PS4-3, which involves planning and conducting an investigation to determine the effect of placing objects made with different materials in the path of a beam of light, focusing on observing and recording results. Different materials affect light in different ways: transparent materials like clear plastic or glass let all light pass through, allowing us to see through them clearly with bright light; translucent materials like wax paper or tissue let some light pass through, making the light dim and shadows light gray; opaque materials like cardboard or wood block light completely, creating dark shadows, while some shiny materials like mirrors or foil reflect light back. Sofia tested four materials, and the results showed: glass let all light through, tissue let some light through, poster board blocked light, and mirror reflected light. The pattern is clear: material type determines the effect on light, with one material letting all light through, one letting some, one blocking it, and one reflecting it. The correct answer says 'Different materials changed light in different ways' which accurately describes the pattern in the data, showing understanding that materials have different properties like transparent allowing full passage, translucent partial, opaque blocking, and reflective bouncing light, as the data clearly shows these varied effects. A distractor like 'All materials blocked light, so the room stayed dark' is wrong because it claims all materials are the same in blocking when the data shows differences like all through for glass and some for tissue; students might choose this if they focus on a single material like poster board and not the overall results or confuse blocking with other properties. To help students, ask: 'Which materials let light through? Which blocked light? Are there groups with similar results?' Create visual sorting with picture cards of materials into 'light passes,' 'some light,' 'light blocked' piles, explain categories like transparent for clear views, translucent for blurry light, opaque for no light, demonstrate with hand visibility through examples, connect to everyday items like windows or walls, and watch for students who don't recognize materials can be grouped by similar light effects.

Question 6

Look at Marcus's results: clear ruler=bright, wax paper=dim, cardboard=dark, spoon=reflected. What pattern do you see?

  1. All materials let all light pass through the same way.
  2. Clear ruler let light pass, but cardboard blocked light. (correct answer)
  3. Cardboard let light pass through, and wax paper blocked it.
  4. The metal spoon was shiny when Marcus shined the light.
Explanation: This question assesses the skill 1-PS4-3, which involves planning and conducting an investigation to determine the effect of placing objects made with different materials in the path of a beam of light, focusing on observing and recording results. Different materials affect light in different ways: transparent materials like clear plastic or glass let all light pass through, allowing us to see through them clearly with bright light; translucent materials like wax paper or tissue let some light pass through, making the light dim and shadows light gray; opaque materials like cardboard or wood block light completely, creating dark shadows, while some shiny materials like mirrors or foil reflect light back. Marcus tested four materials, and the results showed: clear ruler let light through brightly, wax paper let some light through dimly, cardboard blocked light creating a dark shadow, and spoon reflected light. The pattern is clear: material type determines the effect on light, with two materials letting light through (one fully, one partially), one blocking it, and one reflecting it. The correct answer says 'Clear ruler let light pass, but cardboard blocked light' which accurately describes the pattern in the data of different effects, showing understanding that materials have different properties like transparent allowing light to pass and opaque blocking it, as the data clearly shows these contrasts. A distractor like 'All materials let all light pass through the same way' is wrong because it claims all materials are the same when the data shows varied effects such as bright, dim, dark, and reflected; students might choose this if they don't recognize the pattern across multiple observations and expect all materials to behave identically. To help students, ask: 'Which materials let light through? Which blocked light? Are there groups with similar results?' Create visual sorting with picture cards of materials into 'light passes,' 'some light,' 'light blocked' piles, explain categories like transparent for clear views, translucent for blurry light, opaque for no light, demonstrate with hand visibility through examples, connect to everyday items like windows or walls, and watch for students who attribute light passing to unrelated properties like color instead of transparency.

Question 7

Sofia's window results: glass→all light; thin curtain→some light; poster board→blocked; mirror→reflected. What is true about how materials affect light?

  1. All materials let all light pass through every time.
  2. Glass blocked light, but poster board let light through.
  3. Some materials pass light, some block it, and some reflect it. (correct answer)
  4. Only color decided what happened to the light.
Explanation: This question assesses the skill 1-PS4-3: Plan and conduct an investigation to determine the effect of placing objects made with different materials in the path of a beam of light - observing and recording results part. Different materials affect light in different ways. Transparent materials (like clear plastic, glass) let all light pass through - we can see through them and light shines through brightly. Translucent materials (like wax paper, tissue) let some light pass through - light is dim, shadows are light gray. Opaque materials (like cardboard, wood, thick cloth) block light completely - no light passes through, shadows are dark. Some shiny materials (mirror, foil) also reflect light back. Sofia tested 4 materials. Results showed: glass let all light through (all light), thin curtain let some light through (some light), poster board blocked light (blocked), mirror reflected light (reflected). The pattern is clear: material type determines effect on light. 2 materials let light through, 1 blocked light, 1 reflected. The correct answer says 'Some materials pass light, some block it, and some reflect it' which accurately describes the pattern in data. This shows understanding that materials have different properties: some are transparent (light passes through), some translucent (some light passes), some opaque (light blocked). The data clearly shows these different effects. An error type like 'All materials let all light pass through every time' is wrong because it claims all materials same when data shows different effects. Students might choose this if they don't recognize pattern across multiple observations, focus on single material not overall results, confuse material properties with light transmission, expect all materials to behave the same way, don't understand categories like transparent vs opaque. Help students analyze data by asking: 'Which materials let light through? Which blocked light? Are there groups with similar results?' Create visual sorting: picture cards of materials, sort into 'light passes' 'some light' 'light blocked' piles. Explain categories: Transparent = see through clearly, light passes. Translucent = see shapes/light but blurry, some light passes. Opaque = cannot see through, blocks light. Demonstrate: 'Can you see my hand through clear plastic? Yes - transparent. Through wax paper? A little - translucent. Through cardboard? No - opaque.' Connect to everyday: windows (transparent glass), shower curtain (translucent), walls (opaque). Watch for: students who don't recognize materials can be grouped by similar light effects, or who attribute light passing to unrelated properties like color, weight, or texture instead of transparency.

Question 8

Marcus tested: clear ruler=bright spot, wax paper=dim glow, cardboard=dark shadow, spoon=reflected. Which materials let light pass through?

  1. Cardboard and metal spoon let light pass through completely.
  2. Clear ruler and wax paper let some or all light pass through. (correct answer)
  3. Metal spoon and cardboard let some light pass through dimly.
  4. Only the metal spoon let light pass through to the wall.
Explanation: This question assesses the skill 1-PS4-3, which involves planning and conducting an investigation to determine the effect of placing objects made with different materials in the path of a beam of light, focusing on observing and recording results. Different materials affect light in different ways: transparent materials like clear plastic or glass let all light pass through, allowing us to see through them clearly with bright light; translucent materials like wax paper or tissue let some light pass through, making the light dim and shadows light gray; opaque materials like cardboard or wood block light completely, creating dark shadows, while some shiny materials like mirrors or foil reflect light back. Marcus tested four materials, and the results showed: clear ruler created a bright spot (full passage), wax paper a dim glow (partial), cardboard a dark shadow (blocked), and spoon reflected. The pattern is clear: material type determines the effect on light, with two materials letting light through (fully or partially), one blocking, and one reflecting. The correct answer says 'Clear ruler and wax paper let some or all light pass through' which accurately describes the correct classification of materials that allowed light passage, showing understanding that transparent and translucent properties let light through, as the data clearly shows bright and dim effects. A distractor like 'Cardboard and metal spoon let light pass through completely' is wrong because it misclassifies opaque and reflective as passing light when they blocked or reflected instead; students might choose this if they confuse blocking or reflecting with transmission. To help students, ask: 'Which materials let light through? Which blocked light? Are there groups with similar results?' Create visual sorting with picture cards of materials into 'light passes,' 'some light,' 'light blocked' piles, explain categories like transparent for clear views, translucent for blurry light, opaque for no light, demonstrate with hand visibility through examples, connect to everyday items like windows or walls, and watch for students who don't distinguish between passing through and reflecting.

Question 9

Chen's shadows: bottle=no shadow, screen=light gray, page=medium gray, book=dark. What is true about blocking light?

  1. Darker shadows showed more light was blocked by the material. (correct answer)
  2. Darker shadows showed more light passed through the material.
  3. All shadows were the same, so materials did not matter.
  4. Clear bottle made a dark shadow because clear means opaque.
Explanation: This question assesses the skill 1-PS4-3, which involves planning and conducting an investigation to determine the effect of placing objects made with different materials in the path of a beam of light, focusing on observing and recording results. Different materials affect light in different ways: transparent materials like clear plastic or glass let all light pass through, allowing us to see through them clearly with bright light; translucent materials like wax paper or tissue let some light pass through, making the light dim and shadows light gray; opaque materials like cardboard or wood block light completely, creating dark shadows, while some shiny materials like mirrors or foil reflect light back. Chen tested four materials, and the results showed shadows: bottle with no shadow (all through), screen light gray (some through), page medium gray (partial), and book dark (blocked). The pattern is clear: material type determines the effect on light, with darker shadows indicating more blocking. The correct answer says 'Darker shadows showed more light was blocked by the material' which accurately describes the pattern relating shadow darkness to light blocking, showing understanding that opaque materials create darker shadows by blocking more light, as the data clearly progresses from no shadow to dark. A distractor like 'Darker shadows showed more light passed through the material' is wrong because it reverses the relationship, claiming passage causes darkness when blocking does; students might choose this if they confuse more passage with darker shadows or don't understand the inverse relation. To help students, ask: 'Which materials let light through? Which blocked light? Are there groups with similar results?' Create visual sorting with picture cards of materials into 'light passes,' 'some light,' 'light blocked' piles, explain categories like transparent for clear views, translucent for blurry light, opaque for no light, demonstrate with hand visibility through examples, connect to everyday items like windows or walls, and watch for students who reverse the concept of shadow darkness and light passage.

Question 10

Sofia saw: tissue=blurry shapes, glass=clear view, poster board=no view, mirror=bounced light. Which materials had similar effects on light?

  1. Glass and poster board both let all light pass through.
  2. Poster board and mirror both did not let light pass through. (correct answer)
  3. Tissue paper and glass both blocked all light from the room.
  4. Mirror and tissue paper both let some light pass through.
Explanation: This question assesses the skill 1-PS4-3, which involves planning and conducting an investigation to determine the effect of placing objects made with different materials in the path of a beam of light, focusing on observing and recording results. Different materials affect light in different ways: transparent materials like clear plastic or glass let all light pass through, allowing us to see through them clearly with bright light; translucent materials like wax paper or tissue let some light pass through, making the light dim and shadows light gray; opaque materials like cardboard or wood block light completely, creating dark shadows, while some shiny materials like mirrors or foil reflect light back. Sofia tested four materials, and the results showed: tissue allowed blurry shapes (some through), glass clear view (all through), poster board no view (blocked), and mirror bounced light (reflected). The pattern is clear: material type determines the effect on light, with one letting all through, one some, one blocking, and one reflecting, grouping poster board and mirror as not letting light pass through. The correct answer says 'Poster board and mirror both did not let light pass through' which accurately describes the similar effects in classification, showing understanding that opaque and reflective materials prevent light passage, as the data clearly shows no view and bounced light. A distractor like 'Glass and poster board both let all light pass through' is wrong because it pairs transparent glass with opaque poster board, claiming both pass light when poster board blocked it; students might choose this if they focus on unrelated properties like flatness instead of light effects. To help students, ask: 'Which materials let light through? Which blocked light? Are there groups with similar results?' Create visual sorting with picture cards of materials into 'light passes,' 'some light,' 'light blocked' piles, explain categories like transparent for clear views, translucent for blurry light, opaque for no light, demonstrate with hand visibility through examples, connect to everyday items like windows or walls, and watch for students who don't group materials by similar light-blocking effects.

Question 11

Keisha saw: mirror→reflected; clear plastic→bright through; wax paper→dim through; black cloth→no light. Which materials have similar effects on light?

  1. Clear plastic and wax paper both blocked all light.
  2. Mirror and black cloth both stopped light from going through. (correct answer)
  3. Wax paper and black cloth both let all light pass through.
  4. Only clear plastic mattered, because it was see-through.
Explanation: This question assesses the skill 1-PS4-3: Plan and conduct an investigation to determine the effect of placing objects made with different materials in the path of a beam of light - observing and recording results part. Different materials affect light in different ways. Transparent materials (like clear plastic, glass) let all light pass through - we can see through them and light shines through brightly. Translucent materials (like wax paper, tissue) let some light pass through - light is dim, shadows are light gray. Opaque materials (like cardboard, wood, thick cloth) block light completely - no light passes through, shadows are dark. Some shiny materials (mirror, foil) also reflect light back. Keisha tested 4 materials. Results showed: mirror reflected light (reflected), clear plastic let all light through (bright through), wax paper let some light through (dim through), black cloth blocked all light (no light). The pattern is clear: material type determines effect on light. 2 materials let light through, 1 blocked light, 1 reflected. The correct answer says 'Mirror and black cloth both stopped light from going through' which accurately describes the correct classification of materials. This shows understanding that materials have different properties: some are transparent (light passes through), some translucent (some light passes), some opaque (light blocked). The data clearly shows these different effects. An error type like 'Clear plastic and wax paper both blocked all light' is wrong because it misclassifies which materials blocked vs allowed light. Students might choose this if they don't recognize pattern across multiple observations, focus on single material not overall results, confuse material properties with light transmission, expect all materials to behave the same way, don't understand categories like transparent vs opaque. Help students analyze data by asking: 'Which materials let light through? Which blocked light? Are there groups with similar results?' Create visual sorting: picture cards of materials, sort into 'light passes' 'some light' 'light blocked' piles. Explain categories: Transparent = see through clearly, light passes. Translucent = see shapes/light but blurry, some light passes. Opaque = cannot see through, blocks light. Demonstrate: 'Can you see my hand through clear plastic? Yes - transparent. Through wax paper? A little - translucent. Through cardboard? No - opaque.' Connect to everyday: windows (transparent glass), shower curtain (translucent), walls (opaque). Watch for: students who don't recognize materials can be grouped by similar light effects, or who attribute light passing to unrelated properties like color, weight, or texture instead of transparency.

Question 12

Jamal sorted: all through=glass, wrap, clear bottle; some through=tissue, thin paper, screen; not through=cardboard, wood, cloth. Which materials blocked light?

  1. Clear glass and plastic wrap blocked light and made dark shadows.
  2. Cardboard, wood block, and dark cloth did not let light through. (correct answer)
  3. Tissue paper and mesh screen blocked all light completely.
  4. Mirror blocked light in Jamal's sort of materials.
Explanation: This question assesses the skill 1-PS4-3, which involves planning and conducting an investigation to determine the effect of placing objects made with different materials in the path of a beam of light, focusing on observing and recording results. Different materials affect light in different ways: transparent materials like clear plastic or glass let all light pass through, allowing us to see through them clearly with bright light; translucent materials like wax paper or tissue let some light pass through, making the light dim and shadows light gray; opaque materials like cardboard or wood block light completely, creating dark shadows, while some shiny materials like mirrors or foil reflect light back. Jamal sorted multiple materials into groups: all through like glass, wrap, clear bottle; some through like tissue, thin paper, screen; not through like cardboard, wood, cloth. The pattern is clear: material type determines the effect on light, with three materials letting all through, three letting some, and three blocking it. The correct answer says 'Cardboard, wood block, and dark cloth did not let light through' which accurately describes the correct classification of materials that blocked light, showing understanding that opaque materials block light fully, as the data clearly groups them in 'not through.' A distractor like 'Clear glass and plastic wrap blocked light and made dark shadows' is wrong because it reverses transparent and opaque, claiming transparent materials block when they let all light through; students might choose this if they confuse categories like transparent vs opaque. To help students, ask: 'Which materials let light through? Which blocked light? Are there groups with similar results?' Create visual sorting with picture cards of materials into 'light passes,' 'some light,' 'light blocked' piles, explain categories like transparent for clear views, translucent for blurry light, opaque for no light, demonstrate with hand visibility through examples, connect to everyday items like windows or walls, and watch for students who don't understand materials can be grouped by light effects.

Question 13

Marcus recorded: clear ruler→bright; plastic wrap→bright; wax paper→dim; cardboard→dark; metal spoon→reflected. Which materials blocked light?

  1. Clear ruler and plastic wrap blocked the light.
  2. Wax paper and plastic wrap blocked the light.
  3. Cardboard blocked the light and made a dark shadow. (correct answer)
  4. All materials blocked the light and made dark shadows.
Explanation: This question assesses the skill 1-PS4-3: Plan and conduct an investigation to determine the effect of placing objects made with different materials in the path of a beam of light - observing and recording results part. Different materials affect light in different ways. Transparent materials (like clear plastic, glass) let all light pass through - we can see through them and light shines through brightly. Translucent materials (like wax paper, tissue) let some light pass through - light is dim, shadows are light gray. Opaque materials (like cardboard, wood, thick cloth) block light completely - no light passes through, shadows are dark. Some shiny materials (mirror, foil) also reflect light back. Marcus tested 5 materials. Results showed: clear ruler let all light through (bright), plastic wrap let all light through (bright), wax paper let some light through (dim), cardboard blocked all light (dark), metal spoon reflected light (reflected). The pattern is clear: material type determines effect on light. 3 materials let light through, 1 blocked light, 1 reflected. The correct answer says 'Cardboard blocked the light and made a dark shadow' which accurately describes the specific observations. This shows understanding that materials have different properties: some are transparent (light passes through), some translucent (some light passes), some opaque (light blocked). The data clearly shows these different effects. An error type like 'All materials blocked the light and made dark shadows' is wrong because it claims all materials same when data shows different effects. Students might choose this if they don't recognize pattern across multiple observations, focus on single material not overall results, confuse material properties with light transmission, expect all materials to behave the same way, don't understand categories like transparent vs opaque. Help students analyze data by asking: 'Which materials let light through? Which blocked light? Are there groups with similar results?' Create visual sorting: picture cards of materials, sort into 'light passes' 'some light' 'light blocked' piles. Explain categories: Transparent = see through clearly, light passes. Translucent = see shapes/light but blurry, some light passes. Opaque = cannot see through, blocks light. Demonstrate: 'Can you see my hand through clear plastic? Yes - transparent. Through wax paper? A little - translucent. Through cardboard? No - opaque.' Connect to everyday: windows (transparent glass), shower curtain (translucent), walls (opaque). Watch for: students who don't recognize materials can be grouped by similar light effects, or who attribute light passing to unrelated properties like color, weight, or texture instead of transparency.

Question 14

Chen made shadows: plastic bottle→no shadow; window screen→light gray; notebook page→medium gray; thick book→dark. Which material made the darkest shadow?

  1. Plastic bottle
  2. Window screen
  3. Thick book (correct answer)

Explanation: This question assesses the skill 1-PS4-3: Plan and conduct an investigation to determine the effect of placing objects made with different materials in the path of a beam of light - observing and recording results part. Different materials affect light in different ways. Transparent materials (like clear plastic, glass) let all light pass through - we can see through them and light shines through brightly. Translucent materials (like wax paper, tissue) let some light pass through - light is dim, shadows are light gray. Opaque materials (like cardboard, wood, thick cloth) block light completely - no light passes through, shadows are dark. Some shiny materials (mirror, foil) also reflect light back. Chen tested 4 materials. Results showed: plastic bottle let all light through (no shadow), window screen let some light through (light gray), notebook page let some light through (medium gray), thick book blocked all light (dark). The pattern is clear: material type determines effect on light. 3 materials let light through, 1 blocked light. The correct answer says 'Thick book' which accurately describes the correct classification of materials based on specific observations. This shows understanding that materials have different properties: some are transparent (light passes through), some translucent (some light passes), some opaque (light blocked). The data clearly shows these different effects. An error type like 'Plastic bottle' is wrong because it misclassifies which materials blocked vs allowed light. Students might choose this if they don't recognize pattern across multiple observations, focus on single material not overall results, confuse material properties with light transmission, expect all materials to behave the same way, don't understand categories like transparent vs opaque. Help students analyze data by asking: 'Which materials let light through? Which blocked light? Are there groups with similar results?' Create visual sorting: picture cards of materials, sort into 'light passes' 'some light' 'light blocked' piles. Explain categories: Transparent = see through clearly, light passes. Translucent = see shapes/light but blurry, some light passes. Opaque = cannot see through, blocks light. Demonstrate: 'Can you see my hand through clear plastic? Yes - transparent. Through wax paper? A little - translucent. Through cardboard? No - opaque.' Connect to everyday: windows (transparent glass), shower curtain (translucent), walls (opaque). Watch for: students who don't recognize materials can be grouped by similar light effects, or who attribute light passing to unrelated properties like color, weight, or texture instead of transparency.

Question 15

Look at Marcus's flashlight table: Clear ruler→bright spot; wax paper→dim glow; cardboard→no light; metal spoon→shiny bounce. What pattern do you see?

  1. All materials let all light pass through the same way.
  2. Clear ruler let light through, but cardboard blocked light. (correct answer)
  3. Cardboard let light pass through, and wax paper blocked all light.
  4. Only the metal spoon mattered, because it was shiny.
Explanation: This question assesses the skill 1-PS4-3: Plan and conduct an investigation to determine the effect of placing objects made with different materials in the path of a beam of light - observing and recording results part. Different materials affect light in different ways. Transparent materials (like clear plastic, glass) let all light pass through - we can see through them and light shines through brightly.

Marcus tested 4 materials. Results showed: clear ruler let all light through (bright spot), wax paper let some light through (dim glow), cardboard blocked all light (no light), metal spoon reflected light (shiny bounce). The pattern is clear: material type determines effect on light. 2 materials let light through, 1 blocked light, 1 reflected. The correct answer says 'Clear ruler let light through, but cardboard blocked light' which accurately describes the pattern in data showing contrasting effects. This shows understanding that materials have different properties: some are transparent (light passes through), some translucent (some light passes), some opaque (light blocked). The data clearly shows these different effects. An error type like 'All materials let all light pass through the same way' is wrong because it claims all materials same when data shows different effects. Students might choose this if they don't recognize pattern across multiple observations, focus on single material not overall results, confuse material properties with light transmission, expect all materials to behave the same way, don't understand categories like transparent vs opaque. Help students analyze data by asking: 'Which materials let light through? Which blocked light? Are there groups with similar results?'

Question 16

Emma tested twice: clear lid=bright both times, wax paper=dim both times, cardboard=dark both times, foil=reflected both times. What pattern do you see?

  1. Each material acted the same in both trials every time. (correct answer)
  2. Wax paper changed from dim to bright in the second trial.
  3. Cardboard let more light through the second time Emma tried.
  4. The flashlight got weaker each time, so results changed.
Explanation: This question assesses the skill 1-PS4-3, which involves planning and conducting an investigation to determine the effect of placing objects made with different materials in the path of a beam of light, focusing on observing and recording results. Different materials affect light in different ways: transparent materials like clear plastic or glass let all light pass through, allowing us to see through them clearly with bright light; translucent materials like wax paper or tissue let some light pass through, making the light dim and shadows light gray; opaque materials like cardboard or wood block light completely, creating dark shadows, while some shiny materials like mirrors or foil reflect light back. Emma tested four materials twice, and the results showed: clear lid was bright both times, wax paper dim both times, cardboard dark both times, and foil reflected both times. The pattern is clear: material type determines the effect on light consistently across trials, with one letting all through, one some, one blocking, and one reflecting. The correct answer says 'Each material acted the same in both trials every time' which accurately describes the pattern in the data of consistent results, showing understanding that materials have stable properties like transparency or opacity, as the data clearly shows no changes between trials. A distractor like 'Wax paper changed from dim to bright in the second trial' is wrong because it claims a change not supported by data where wax paper was dim both times; students might choose this if they don't analyze repeated observations carefully or expect variability. To help students, ask: 'Which materials let light through? Which blocked light? Are there groups with similar results?' Create visual sorting with picture cards of materials into 'light passes,' 'some light,' 'light blocked' piles, explain categories like transparent for clear views, translucent for blurry light, opaque for no light, demonstrate with hand visibility through examples, connect to everyday items like windows or walls, and watch for students who attribute changes to unrelated factors like flashlight strength instead of material properties.

Question 17

Keisha tested: mirror=reflected, clear plastic=bright, frosted plastic=dim, black cloth=blocked. What is true about materials and light?

  1. Clear plastic and black cloth both let all light pass through.
  2. Mirror let light pass through, so it made no shadow.
  3. Some materials let light through, and some block or reflect it. (correct answer)
  4. All materials made the same bright spot on the wall.
Explanation: This question assesses the skill 1-PS4-3, which involves planning and conducting an investigation to determine the effect of placing objects made with different materials in the path of a beam of light, focusing on observing and recording results. Different materials affect light in different ways: transparent materials like clear plastic or glass let all light pass through, allowing us to see through them clearly with bright light; translucent materials like wax paper or tissue let some light pass through, making the light dim and shadows light gray; opaque materials like cardboard or wood block light completely, creating dark shadows, while some shiny materials like mirrors or foil reflect light back. Keisha tested four materials, and the results showed: mirror reflected light, clear plastic let light through brightly, frosted plastic let light through dimly, and black cloth blocked light. The pattern is clear: material type determines the effect on light, with one material letting all through, one letting some, one blocking, and one reflecting. The correct answer says 'Some materials let light through, and some block or reflect it' which accurately describes the pattern in the data, showing understanding that materials have different properties like transparent and translucent allowing passage, opaque blocking, and reflective bouncing light, as the data clearly shows these categories. A distractor like 'All materials made the same bright spot on the wall' is wrong because it claims all materials are the same when data shows varied effects like bright, dim, blocked, and reflected; students might choose this if they don't recognize the pattern and focus on one material like clear plastic. To help students, ask: 'Which materials let light through? Which blocked light? Are there groups with similar results?' Create visual sorting with picture cards of materials into 'light passes,' 'some light,' 'light blocked' piles, explain categories like transparent for clear views, translucent for blurry light, opaque for no light, demonstrate with hand visibility through examples, connect to everyday items like windows or walls, and watch for students who confuse material properties with light transmission.

Question 18

Chen saw: clear bottle=no shadow, screen=light gray, page=medium gray, book=dark. Which made the darkest shadow?

  1. Clear plastic bottle made the darkest shadow on the wall.
  2. Window screen made the darkest shadow on the wall.
  3. Thick book made the darkest shadow on the wall. (correct answer)
  4. Notebook page made the darkest shadow on the wall.
Explanation: This question assesses the skill 1-PS4-3, which involves planning and conducting an investigation to determine the effect of placing objects made with different materials in the path of a beam of light, focusing on observing and recording results. Different materials affect light in different ways: transparent materials like clear plastic or glass let all light pass through, allowing us to see through them clearly with bright light; translucent materials like wax paper or tissue let some light pass through, making the light dim and shadows light gray; opaque materials like cardboard or wood block light completely, creating dark shadows, while some shiny materials like mirrors or foil reflect light back. Chen tested four materials, and the results showed: clear bottle created no shadow, window screen made a light gray shadow, notebook page made a medium gray shadow, and thick book made a dark shadow. The pattern is clear: material type determines the effect on light, with one material letting all light through (no shadow), two letting some (gray shadows), and one blocking it completely (dark shadow). The correct answer says 'Thick book made the darkest shadow on the wall' which accurately describes the specific observations of shadow darkness, showing understanding that materials have different properties like opaque ones blocking light fully to create the darkest shadows, as the data clearly shows the book as darkest. A distractor like 'Clear plastic bottle made the darkest shadow on the wall' is wrong because it misclassifies the transparent bottle which let all light through with no shadow, not dark; students might choose this if they confuse transparent with opaque or don't understand shadow darkness relates to light blocking. To help students, ask: 'Which materials let light through? Which blocked light? Are there groups with similar results?' Create visual sorting with picture cards of materials into 'light passes,' 'some light,' 'light blocked' piles, explain categories like transparent for clear views, translucent for blurry light, opaque for no light, demonstrate with hand visibility through examples, connect to everyday items like windows or walls, and watch for students who attribute shadow darkness to unrelated properties like color instead of transparency.

Question 19

Chen's shadow test: screen→light gray; notebook page→medium gray; thick book→dark. What pattern do you see in the results?

  1. Darker shadows meant more light was blocked by the material. (correct answer)
  2. All shadows were the same, so materials did not matter.
  3. The thick book let the most light pass through.
  4. Only the lamp changed, not the materials he tested.

The pattern is clear: material type determines effect on light. 2 materials let some light through, 1 blocked light. The correct answer says 'Darker shadows meant more light was blocked by the material' which accurately describes the pattern in data. This shows understanding that materials have different properties: some are transparent (light passes through), some translucent (some light passes), some opaque (light blocked). The data clearly shows these different effects. An error type like 'All shadows were the same, so materials did not matter' is wrong because it claims all materials same when data shows different effects.

Question 20

Emma tested twice: clear lid→bright both times; wax paper→dim both times; cardboard→dark both times; foil→shiny bounce both times. What is true about her results?

  1. Each material acted the same way both times she tested. (correct answer)
  2. The clear lid blocked light the second time she tested.
  3. All materials let the same amount of light pass through.
  4. Only foil mattered, because it was the brightest material.
