Read Maya’s plan: Shine a lamp at a wall. Hold plastic wrap, paper, and a book. Which will make a dark shadow?
Plastic wrap will make a dark shadow
The thick book will make a dark shadow
White paper will make no shadow at all
All three will make the same dark shadow
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 - planning investigation part. This investigation tests how different materials affect light. Some materials let light pass through them - we call these transparent (like clear plastic or glass). Some materials let only some light through - translucent (like wax paper). Other materials block light completely - opaque (like cardboard or wood). When light is blocked, we see a shadow. Testing different materials helps us understand they have different properties. Maya's plan tests three materials: plastic wrap, paper, and a book. The procedure is: shine a lamp at the wall, then hold each material in the beam, observing shadows. Maya should observe if the shadow is dark, light, or none, depending on if light is blocked completely, partially, or not at all. Different materials will show different results. The correct answer says 'The thick book will make a dark shadow' which correctly identifies the prediction that opaque blocks light. This shows understanding that materials have different properties related to light transmission. A distractor like 'All three will make the same dark shadow' is wrong because it claims all materials have the same effect. Students might choose this if they don't understand materials have different properties. Before investigation, show examples: 'Can you see through clear plastic? Can you see through cardboard?' to establish transparent vs. opaque. During investigation: 'What do you see on the wall? Bright light, dim light, or dark/shadow?' Record results in simple chart: Material | Light passes? (yes/some/no). Explain: Transparent materials have properties that let light pass through. Opaque materials' properties block light. That's why we can see through windows (glass is transparent) but not walls (opaque). Connect to everyday: 'Why can you see through your water bottle but not your lunchbox?' Watch for: students who focus on unrelated properties (color, weight, size) instead of light transmission, or who think all materials should affect light the same way.
Read Marcus’s plan: Shine a lamp at a wall. Hold plastic wrap, paper, and a book. What should Marcus observe?
If the wall feels warm to the touch
If the materials smell different in the light
If the shadow on the wall is dark, light, or none
If the lamp is taller than the book

The procedure is: shine a lamp at the wall, hold each material, and observe shadows. Marcus should observe if the shadow on the wall is dark, light, or none, based on light transmission. Different materials will show different results. The correct answer says 'If the shadow on the wall is dark, light, or none' which correctly identifies what to observe. This shows understanding that materials have different properties related to light transmission. A distractor like 'If the materials smell different in the light' is wrong because it focuses on an irrelevant material property. Students might choose this if they confuse properties like smell with light transmission. Before investigation, show examples: 'Can you see through clear plastic? Can you see through cardboard?' to establish transparent vs. opaque. During investigation: 'What do you see on the wall? Bright light, dim light, or dark/shadow?'

Read Sofia’s plan: She shines a flashlight through materials. What will happen when light hits cardboard?
The light will pass through and get brighter
The light will turn into sound and disappear
The light will be blocked and make a dark shadow
The light will pass through and stay bright

Testing different materials helps us understand they have different properties. Sofia's plan tests materials by shining a flashlight through them. The procedure is: shine the light through each material and observe what happens. Sofia should observe if light passes through completely, partially, or not at all, noting if there's a bright spot, dim spot, or dark shadow. Different materials will show different results. The correct answer says 'The light will be blocked and make a dark shadow' which correctly identifies the prediction that opaque materials like cardboard block light. This shows understanding that materials have different properties related to light transmission. A distractor like 'The light will pass through and stay bright' is wrong because it reverses opaque predictions for cardboard. Students might choose this if they don't predict based on material type. Before investigation, show examples: 'Can you see through clear plastic? Can you see through cardboard?' to establish transparent vs. opaque. During investigation: 'What do you see on the wall?

Read Carlos’s plan: Shine a flashlight at a wall, then hold wax paper in front. What will happen to the light?
The light will be gone because no light passes through
The light will get brighter than before
The light will be dim because some light passes through
The light will change into water on the wall

Testing different materials helps us understand they have different properties. Carlos's plan tests wax paper by shining a flashlight at a wall then holding it in front. The procedure is: shine the light, hold the material, and observe the light on the wall. Carlos should observe if light passes partially, making it dim, or other effects. Different materials will show different results. The correct answer says 'The light will be dim because some light passes through' which correctly identifies the prediction for translucent materials. This shows understanding that materials have different properties related to light transmission. A distractor like 'The light will be gone because no light passes through' is wrong because it reverses translucent predictions. Students might choose this if they don't predict based on material type. Before investigation, show examples: 'Can you see through clear plastic?

Read Yuki’s plan: Shine a flashlight at a wall. Hold clear plastic, then wax paper. Which step comes next?
Look away and stop the investigation
Hold cardboard in front of the light
Shake the flashlight to make more light
Tape the materials to the ceiling

Testing different materials helps us understand they have different properties. Yuki's plan tests materials: clear plastic, wax paper, and implied cardboard. The procedure is: shine flashlight at wall, hold clear plastic, then wax paper, then cardboard, observing each. Yuki should observe if light passes completely, partially, or not at all, with varying shadows. Different materials will show different results. The correct answer says 'Hold cardboard in front of the light' which correctly identifies the proper procedure for testing materials systematically. This shows understanding that materials have different properties related to light transmission. A distractor like 'Look away and stop the investigation' is wrong because it describes a wrong procedure. Students might choose this if they don't understand the sequence in planning.
