- Jamal builds an umbrella over the hot sandbox. What does it do?
Answer: It blocks sunlight by going between sun and sandbox.
This question tests kindergarten understanding of building simple structures to block or reduce sunlight on an area (K-PS3-2: Use tools and materials to design and build a structure that will reduce the warming effect of sunlight). To block sunlight and create shade, we need a structure between the sun and the area we want to protect. The structure must be made of material that sunlight cannot shine through (opaque materials like cardboard, fabric, wood, metal, not clear plastic or glass). When positioned correctly - above and between the sun and the area - the structure blocks sun rays from reaching the surface, creating shade underneath. In this picture/story, Jamal builds an umbrella over the hot sandbox to block sun from the sandbox. The umbrella is made of fabric which blocks sunlight and sun cannot shine through. Jamal positions it above the sandbox where sun is shining from so it creates shade and keeps area cooler. Choice B is correct because it accurately describes blocking mechanism: the umbrella goes between sun and sandbox to block sunlight. The structure works by blocking sun rays before they reach the sand. Key understanding: blocker must be between sun and area. Choice A is incorrect because it suggests the umbrella makes the sun disappear rather than simply blocking its rays. Kindergarteners often believe structures affect the sun itself rather than blocking its rays from reaching specific areas. To help students understand sun-blocking structures: Demonstrate with flashlight (sun) and toy sandbox. Ask: "How can we make shade on the sandbox?" Test positions: place umbrella next to sandbox (no shade), behind sandbox (no shade), between flashlight and sandbox (shade created!). Show that blocker must go between light source and object. Build real shade structures outside: set up umbrella over sandbox, check if there's shade underneath. Use sun-blocker-area diagram with arrows showing sun rays being blocked by umbrella. Practice language: "The umbrella goes between the sun and the sandbox to block the sun and make shade." Watch for: students who think umbrellas make sun disappear, those who don't understand positioning between sun and area. Emphasize: sun still exists, umbrella just blocks its rays from reaching sandbox, and shade is the cooler area created underneath.
- Chen sets up a canopy. Where should he put it for shade?
Answer: Put it over the bench, between sun and bench.
This question tests kindergarten understanding of building simple structures to block or reduce sunlight on an area (K-PS3-2: Use tools and materials to design and build a structure that will reduce the warming effect of sunlight). To block sunlight and create shade, we need a structure between the sun and the area we want to protect. The structure must be made of material that sunlight cannot shine through (opaque materials like cardboard, fabric, wood, metal, not clear plastic or glass). When positioned correctly - above and between the sun and the area - the structure blocks sun rays from reaching the surface, creating shade underneath. In this picture/story, Chen sets up a canopy to block sun from a bench. The canopy is made of fabric or similar material which blocks sunlight. Chen needs to position it correctly - between sun and bench - so it creates shade on the bench. Choice C is correct because it describes correct positioning: over the bench, between sun and bench. The structure works by blocking sun rays before they reach the bench. Key understanding: position matters - blocker must be between sun and area. Choice B is incorrect because it suggests placing canopy behind the bench, which wouldn't block sun coming from above. Kindergarteners often put blockers in wrong locations without considering where sun comes from or the need to intercept rays before they reach the target area. To help students understand sun-blocking structures: Use flashlight (sun) shining down on toy bench. Ask: "Where should we put the canopy to make shade?" Test positions: behind bench (light still hits bench), beside bench (light still hits bench), over bench between light and bench (shade created!). Show that blocker must intercept light path. Go outside with real canopy: observe sun position (up in sky), place canopy over bench, check for shade creation. Move canopy to wrong positions to show shade disappears. Use position diagrams with arrows showing sun rays being blocked when canopy is over bench. Practice language: "The canopy goes over the bench, between sun and bench." Watch for: students who place blockers behind or beside target areas, those who don't consider sun's position above. Emphasize: sun shines from above, blocker must be between sun and area (over/above), and wrong positions don't create shade.
- Yuki uses poster boards. Where should she place them to block sun?
Answer: Place boards between the sun and the sunny bench.
This question tests kindergarten understanding of building simple structures to block or reduce sunlight on an area (K-PS3-2: Use tools and materials to design and build a structure that will reduce the warming effect of sunlight). To block sunlight and create shade, we need a structure between the sun and the area we want to protect. The structure must be made of material that sunlight cannot shine through (opaque materials like cardboard, fabric, wood, metal, not clear plastic or glass). When positioned correctly - above and between the sun and the area - the structure blocks sun rays from reaching the surface, creating shade underneath. In this picture/story, Yuki uses poster boards to block sun from a sunny bench. The poster boards are made of thick paper/cardboard which blocks sunlight. Yuki needs to position them between the sun and bench so they create shade on the bench. Choice A is correct because it describes correct positioning: place boards between the sun and the sunny bench. The structure works by intercepting sun rays before they reach the bench. Key understanding: blocker must be positioned between sun source and target area. Choice B is incorrect because it suggests placing boards behind the bench away from sunlight, which wouldn't block sun coming from above/front. Kindergarteners often place blockers in non-blocking positions without considering the path from sun to target or thinking any placement will work. To help students understand sun-blocking structures: Use directional demonstration - flashlight shining on toy bench from above/angle. Ask: "Where do we put the poster board to block light?" Test positions: behind bench (light still hits), beside bench (light still hits), between light source and bench (blocked!). Trace light path with finger to show interception point. Go outside with real poster boards and bench. Observe sun position, hold boards in different positions, check where shade appears. Move boards between sun and bench - shade covers bench! Use arrow diagrams showing sun rays traveling toward bench, then being blocked by correctly positioned boards. Practice language: "The boards go between the sun and the bench to block sunlight." Watch for: students placing blockers behind or beside targets, those not considering sun's position. Emphasize: sun has a direction (usually from above), blockers must interrupt sun's path to target, and position between sun and target is critical.
- Maya makes paper-plate blockers. What makes shade on the spot?
Answer: The paper plate blocks sunlight before it hits the spot.
This question tests kindergarten understanding of building simple structures to block or reduce sunlight on an area (K-PS3-2: Use tools and materials to design and build a structure that will reduce the warming effect of sunlight). To block sunlight and create shade, we need a structure between the sun and the area we want to protect. The structure must be made of material that sunlight cannot shine through (opaque materials like cardboard, fabric, wood, metal, not clear plastic or glass). When positioned correctly - above and between the sun and the area - the structure blocks sun rays from reaching the surface, creating shade underneath. In this picture/story, Maya makes paper-plate blockers on sticks to block sun from a spot. The structure is made of paper plates which block sunlight and sun cannot shine through. Maya positions them between sun and spot so they create shade underneath. Choice A is correct because it accurately describes the blocking mechanism: the paper plate blocks sunlight before it hits the spot. The structure works by stopping sunlight from reaching the surface. Key understanding: the blocker (paper plate) creates the shade. Choice B is incorrect because it confuses cause and effect - suggesting shade blocks the sun rather than the paper plate blocking sun to create shade. Kindergarteners often think shade is something that blocks sun rather than the result of blocking, reversing the cause-effect relationship. To help students understand sun-blocking structures: Demonstrate with flashlight and paper plate on stick. Show light hitting spot directly (bright), then place paper plate between light and spot (shadow appears). Ask: "What made the shadow?" Trace the path: light → hits paper plate → blocked → creates shadow. Remove plate - shadow disappears! Replace plate - shadow returns! This shows plate creates shade. Build paper plate shade makers outside. Observe: paper plate blocks sun, shadow appears underneath. Move plate away - sun hits spot again. Use cause-effect diagram: sun rays → hit paper plate → rays blocked → shade created on spot. Practice language: "The paper plate blocks sun to make shade." Watch for: students who think shade is the blocker rather than the result, confusion about what creates what. Emphasize: blocker (paper plate) causes shade, shade is the dark area created by blocking, and removing blocker removes shade.
- Amir needs shade for a reading spot. Which material works best?
Answer: Use an old sheet because sunlight cannot shine through.
This question tests kindergarten understanding of building simple structures to block or reduce sunlight on an area (K-PS3-2: Use tools and materials to design and build a structure that will reduce the warming effect of sunlight). To block sunlight and create shade, we need a structure between the sun and the area we want to protect. The structure must be made of material that sunlight cannot shine through (opaque materials like cardboard, fabric, wood, metal, not clear plastic or glass). When positioned correctly - above and between the sun and the area - the structure blocks sun rays from reaching the surface, creating shade underneath. In this picture/story, Amir needs to choose materials to build shade for a reading spot. He needs materials that block sunlight - opaque materials like sheets, cardboard, or fabric. An old sheet would be made of fabric which sun cannot shine through and would create shade when positioned correctly. Choice A is correct because it identifies appropriate opaque material: an old sheet that sunlight cannot shine through. The structure works by blocking sun rays with opaque fabric material. Key understanding: materials must be opaque to block sunlight. Choice B is incorrect because it suggests clear plastic blocks all sunlight when actually sun shines right through transparent materials. Kindergarteners often don't understand the difference between transparent and opaque materials or think any covering blocks sun regardless of material properties. To help students understand sun-blocking structures: Material testing station with flashlight - test different materials. Clear plastic (light shines through - no shadow), old sheet (blocks light - creates shadow), string (too small - light goes around), net with holes (light goes through holes). Sort into "blocks sun" and "sun shines through" groups. Build shade structures with different materials over reading spot. Check: Can we see sun through material? Is there shade underneath? Measure shade darkness. Create material property chart with pictures: opaque materials (sheet, cardboard, wood) vs transparent (clear plastic, glass). Practice language: "The sheet blocks sun because sunlight cannot shine through it." Watch for: students choosing transparent materials, those selecting materials too small for coverage, confusion about material properties. Emphasize: opaque means sun cannot shine through, transparent means sun goes through, and size matters - must cover whole area.
- Emma builds a shade that is too small. What should she change?
Answer: Make the cover bigger so it shades the whole area.
We're learning to fix shade problems. A bigger cover blocks more sunlight. Small covers only shade tiny spots.
- Amir sets up an umbrella. What does the umbrella do to sunlight?
Answer: It blocks sun rays, making shade under it.
This tests what umbrellas do. Umbrellas block sun rays from coming down. This makes cool shade underneath them.
- Marcus builds a cardboard tunnel for the hot toy track. Why?
Answer: It blocks sun rays, making shade on the track.
This question tests kindergarten understanding of building simple structures to block or reduce sunlight on an area (K-PS3-2: Use tools and materials to design and build a structure that will reduce the warming effect of sunlight). To block sunlight and create shade, we need a structure between the sun and the area we want to protect. The structure must be made of material that sunlight cannot shine through (opaque materials like cardboard, fabric, wood, metal, not clear plastic or glass). When positioned correctly - above and between the sun and the area - the structure blocks sun rays from reaching the surface, creating shade underneath. In this picture/story, Marcus builds a cardboard tunnel over a hot toy track to block sun from the track. The tunnel is made of cardboard which blocks sunlight and sun cannot shine through. Marcus positions it over the track where sun would shine so it creates shade and keeps track cooler. Choice A is correct because it explains the purpose: blocking sun rays to make shade on the track. The structure works by preventing sun rays from hitting and heating the track. Key understanding: blocking sun creates shade and reduces heating. Choice C is incorrect because it suggests cardboard is see-through like glass, when cardboard is actually opaque and blocks light. Kindergarteners often confuse material properties or don't understand which materials are transparent vs opaque, sometimes thinking all materials work the same way. To help students understand sun-blocking structures: Compare materials with toy track and heat lamp (safe sun substitute). Test: clear plastic tunnel (light goes through, track gets hot), cardboard tunnel (blocks light, track stays cooler). Feel temperature difference! Show how cardboard creates dark tunnel interior while plastic stays bright. Build different track covers: newspaper tent, cardboard tunnel, fabric canopy. Check each: Does light get through? Is there shade inside? Does track feel cooler? Create material comparison chart with pictures: "Blocks Sun" (cardboard, paper, fabric) vs "Sun Goes Through" (clear plastic, glass). Test each material with flashlight. Practice language: "The cardboard tunnel blocks sun rays, making shade to keep the track cooler." Watch for: students confusing opaque and transparent materials, those who don't connect shade with cooling. Emphasize: cardboard blocks light (opaque), shade keeps things cooler, and different materials have different properties.
- Where should Jamal put the umbrella to block sun?
Answer: Put it over the sandbox, between sun and sand.

To block sunlight and create shade, we need a structure between the sun and the area we want to protect. The structure must be made of material that sunlight cannot shine through (opaque materials like cardboard, fabric, wood, metal, not clear plastic or glass). When positioned correctly - above and between the sun and the area - the structure blocks sun rays from reaching the surface, creating shade underneath. Shade areas stay cooler because sun is blocked. In this picture/story, Jamal builds an umbrella to block sun from the sandbox. The structure is made of fabric which blocks sunlight. Jamal needs to position it between sun and sandbox so it creates shade and keeps area cooler. Choice A is correct because it accurately describes blocking mechanism: structure between sun and area, and explains correct positioning over the sandbox. The structure works by blocking sun rays before they reach the area, creating shade underneath. Key understanding: blocker must be between sun and area, materials must be opaque, position matters for blocking. Choice B is incorrect because it suggests wrong positioning under the sand, which doesn't understand blocking concept. Kindergarteners often think any covering works without considering sun position or put blocker in wrong location. To help students understand sun-blocking structures: Demonstrate with flashlight (sun) and toy (area to protect). Ask: 'How can we make shade on the toy?' Test positions: place cardboard next to toy (no shade), behind toy (no shade), between flashlight and toy (shade created!). Show that blocker must go between light source and object. Test materials: clear plastic (light shines through), cardboard (blocks light and creates shadow). Build real shade structures outside: set up umbrella, position cardboard lean-to, create fabric canopy. After building, check: Is there shade? Did we block the sun? Is area cooler? Adjust position if needed. Use sun-blocker-area diagram with arrows showing sun rays being blocked. Practice language: 'The structure goes between the sun and the area to block the sun and make shade.' Watch for: students who don't consider sun position, those who suggest transparent materials, or those who place blockers in non-blocking positions. Emphasize: sun comes from above, blocker must be between sun and area, materials matter (must block light), and shade is the result of successful blocking.
- Keisha puts up poster boards for shade. What size should they be?
Answer: Big enough to cover the sunny spot completely.
This tests choosing the right size. Big boards cover all the sunny spot. Small boards leave sunny patches showing.
- Maya wants to make shade. Which material blocks sunlight best?
Answer: A piece of cloth you cannot see through.
This asks about good shade materials. Cloth you can't see through blocks sun best. Clear plastic and nets let light pass through.
- Yuki makes paper-plate sun blockers. Where should she hold the plate?
Answer: Hold it between the sun and the sunny spot.
This tests where to hold sun blockers. Hold the plate between sun and sunny spot. This blocks sun rays from reaching there.
- Chen wants to shade a bright picnic spot. What should he build?
Answer: Build a fabric canopy over the picnic spot.
This tests planning shade structures. A fabric canopy blocks sunlight well. Tiny hats are too small and clear covers let sun through.
- Keisha wants to block sun from a toy. Which works best?
Answer: A solid cardboard piece that you cannot see through.
This tests choosing blockers. Solid cardboard blocks all sunlight best. Clear plastic and nets with holes let sun pass through.
- Keisha wants the sandbox cooler. What should she do first?
Answer: Put a shade cover where the sun is shining from.
This question tests kindergarten understanding of building simple structures to block or reduce sunlight on an area (K-PS3-2: Use tools and materials to design and build a structure that will reduce the warming effect of sunlight). To block sunlight and create shade, we need a structure between the sun and the area we want to protect. The structure must be made of material that sunlight cannot shine through (opaque materials like cardboard, fabric, wood, metal, not clear plastic or glass). When positioned correctly - above and between the sun and the area - the structure blocks sun rays from reaching the surface, creating shade underneath. In this picture/story, Keisha wants to make the sandbox cooler by blocking sun. She needs to first identify where sun is coming from and position a shade cover to block it. A shade cover or umbrella should be placed where the sun is shining from to intercept rays before they reach sand. Choice A is correct because it identifies the first step: put a shade cover where the sun is shining from. The structure works by blocking sun rays at their source path to the sandbox. Key understanding: identify sun direction first, then position blocker. Choice D is incorrect because it suggests using a clear window which would let sun through rather than block it, showing confusion about transparent vs opaque materials. Kindergarteners often don't consider sun direction first or think any material will block sun, not understanding that clear materials let light through. To help students understand sun-blocking structures: Start with sun observation - go to sandbox, ask "Where is sun coming from?" Point to sun's position in sky. Use hand to cast shadow, showing sun direction. Next, position shade: hold up cardboard or umbrella where sun shines from, watch shadow fall on sandbox. Move blocker to wrong position - shadow moves away from sandbox! Return to correct position between sun and sandbox. Test materials: hold up clear plastic (sun goes through, no shadow), then opaque material (blocks sun, creates shadow). Build permanent shade using observations. Create sun-tracking activity: different times of day, mark where sun is, adjust shade position. Practice language: "First find where sun shines from, then put shade cover there to block it." Watch for: students who don't observe sun position first, those choosing transparent materials. Emphasize: sun position matters, blocker goes where sun comes from, and materials must be opaque to block light.
- Emma wants shade on the sunny bench. What should she build?
Answer: Build a fabric canopy over the bench to block sun.

When positioned correctly - above and between the sun and the area - the structure blocks sun rays from reaching the surface, creating shade underneath. In this picture/story, Emma wants to build a structure to block sun from a sunny bench. She needs to choose materials that block sunlight and position them correctly. A fabric canopy would be made of material that sun cannot shine through and would be positioned over the bench to create shade. Choice A is correct because it identifies appropriate opaque material (fabric) and correct positioning (over the bench). The structure works by blocking sun rays before they reach the bench surface. Key understanding: materials must be opaque and position matters for blocking. Choice B is incorrect because it recommends transparent material (clear plastic) that sun shines through, which would not create shade. Kindergarteners often don't realize clear materials let sun through and think any covering will create shade regardless of material properties. To help students understand sun-blocking structures: Test materials with flashlight - shine light through clear plastic (light passes through), then through fabric (blocks light and creates shadow). Ask: "Which material stops the light?" Build different bench covers: try clear plastic sheet (no shade), then fabric canopy (shade created!). After building, check: Is there shade? Can we see sun through the material? Practice sorting materials: "blocks sun" pile (fabric, cardboard, wood) vs "sun shines through" pile (clear plastic, glass). Use hands-on testing to discover which materials work. Watch for: students who suggest transparent materials, those who think any covering creates shade. Emphasize: materials matter - must block light, not let it through, and opaque materials like fabric create shade while transparent ones don't.
- Emma makes a fabric canopy. How does this structure make shade?
Answer: It blocks sunlight by covering the area from above.
This asks how canopies work. The fabric covers from above and blocks sunlight. Sun can't get through the fabric roof.
- Sofia wants shade on the bright picnic bench. Where should she put the canopy?
Answer: Put it above the bench, between sun and bench.
This asks about where to put shade makers. The canopy must go above the bench to block sun. Behind or under won't make shade on top.
- Maya makes shade for reading. What should hold the sheet?
Answer: Use sticks and clips to hold the sheet up.
This tests building supports. Sticks and clips hold things up strong. Bubbles pop and one string won't hold a sheet steady.
- Carlos sets up a canopy. What does it do to sunlight?
Answer: It blocks sun rays, making shade under the canopy.
We're learning what canopies do. The canopy blocks sun rays from reaching down. This makes cool shade underneath it.
