- Three paper airplanes were tested. Airplane A flew 18 feet and took 8 minutes to fold. Airplane B flew 14 feet and took 3 minutes to fold. Airplane C flew 22 feet and took 12 minutes to fold. Criteria: fly at least 15 feet and fold in under 10 minutes. Which solution best meets the need while following the constraints?
Answer: Airplane A because it meets 15+ feet and is under 10 minutes.
This question tests comparing solutions using criteria (NGSS 3-5-ETS1-2: Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem). Comparing solutions means evaluating how well each option meets the criteria for success. When multiple criteria exist, the best solution meets ALL criteria, not just one impressive feature. In this scenario, students must compare 3 paper airplane designs. The criteria for success are: fly at least 15 feet AND fold in under 10 minutes. Looking at the data: Airplane A flew 18 feet (meets) and took 8 minutes (meets); Airplane B flew 14 feet (fails) and took 3 minutes (meets); Airplane C flew 22 feet (meets) and took 12 minutes (fails). Choice B is correct because Airplane A meets both criteria: it flew 18 feet (exceeds 15-foot minimum) and took 8 minutes to fold (under 10-minute limit), making it the only solution that satisfies all requirements. Choice C represents focusing on the most impressive single feature. Students who choose this may think the farthest-flying airplane (22 feet) is automatically best without checking that it fails the time constraint by taking 12 minutes to fold. To help students: Create a comparison checklist with solutions as rows and criteria as columns, marking pass/fail for each. Ask "Does each airplane meet BOTH the distance AND time requirements?" Emphasize that meeting all criteria is essential. Use sentence frame: "Airplane A is best because it meets both criteria by flying 18 feet in 8 minutes."

In this scenario, students must compare 3 paper airplane solutions: Airplane A (18 feet, 8 minutes), Airplane B (14 feet, 3 minutes), and Airplane C (22 feet, 12 minutes). The criteria for success are must fly at least 15 feet and fold in under 10 minutes. Looking at the data: Airplane A flies 18 feet (meets) and takes 8 minutes (meets), Airplane B flies 14 feet (fails) and takes 3 minutes (meets), Airplane C flies 22 feet (meets) and takes 12 minutes (fails). Choice B is correct because Airplane A is the only solution that meets both criteria: it flies 18 feet (more than the 15-foot minimum) and takes 8 minutes to fold (under the 10-minute limit). Choice A represents focusing on one criterion while ignoring others - students who choose this may think the farthest-flying plane is automatically best without checking if it meets the time constraint. To help students: Create a comparison checklist or table with solutions as rows and criteria as columns, marking yes/no for each. Ask "Does Airplane A meet the distance criterion? The time criterion?" for each solution. Emphasize that "best" means meeting ALL criteria, not just excelling at one.
- Students tested 3 containers to grow beans. Tin can: $1, plants grew 7 inches, water drained well. Glass jar: $2, plants grew 8 inches, water pooled. Paper cup: $0, plants grew 6 inches, water drained well. Criteria: costs $2 or less, plants grow 7+ inches, and drains water. According to the results, which container should students choose?
Answer: Tin can because it costs $1, grew 7 inches, and drains well.
This question tests comparing solutions using criteria (NGSS 3-5-ETS1-2: Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem). Comparing solutions means evaluating how well each option meets the criteria for success. Engineers use data to systematically check each criterion rather than making assumptions based on single factors like price. In this scenario, students must compare 3 container solutions: Tin can ($1, 7 inches, drains well), Glass jar ($2, 8 inches, water pools), and Paper cup ($0, 6 inches, drains well). The criteria for success are costs $2 or less, plants grow 7+ inches, and drains water. Looking at the data: Tin can meets all criteria ($1 ≤ $2, 7 ≥ 7, drains), Glass jar meets cost and growth but fails drainage ($2 ≤ $2, 8 ≥ 7, but pools), Paper cup meets cost and drainage but fails growth ($0 ≤ $2, drains, but 6 < 7). Choice A is correct because the tin can meets all three criteria: it costs $1 (under $2 limit), plants grew 7 inches (meets 7-inch minimum), and water drains well (meets drainage requirement). Choice B represents focusing on one impressive result while ignoring a critical failure - students who choose this may see the tallest plant growth without realizing that poor drainage disqualifies this solution. To help students: Create a comparison checklist marking yes/no for each criterion. Practice identifying when a solution excels in one area but fails in another. Use sentence frame: "Tin can is best because it meets cost, growth, and drainage criteria by costing $1, growing 7 inches, and draining well."
- Read about three paper airplanes and their results. Airplane A flew 18 feet and took 8 minutes to fold. Airplane B flew 14 feet and took 3 minutes to fold. Airplane C flew 22 feet and took 12 minutes to fold. Criteria: must fly at least 15 feet and be foldable in under 10 minutes. Which solution meets all the criteria for success?
Answer: Airplane A because it flies 18 feet and folds in 8 minutes.
This question tests comparing solutions using criteria (NGSS 3-5-ETS1-2: Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem). Comparing solutions means evaluating how well each option meets the criteria for success. Engineers use data and evidence to compare solutions systematically rather than just picking their favorite. When multiple criteria exist (like cost, performance, and time), the best solution meets ALL or MOST criteria, not just one. Sometimes comparing solutions reveals trade-offs - one solution is faster but more expensive, another is cheaper but slower - and engineers must decide which factors matter most. In this scenario, students must compare three solutions: Airplane A, Airplane B, and Airplane C. The criteria for success are flying at least 15 feet and folding in under 10 minutes. Looking at the data: Airplane A flies 18 feet in 8 minutes, Airplane B flies 14 feet in 3 minutes, and Airplane C flies 22 feet in 12 minutes. To find the best solution, check which option meets all criteria or performs best overall. Choice B is correct because it selects Airplane A, which flies 18 feet (over 15 feet) and folds in 8 minutes (under 10 minutes), meeting both criteria while Airplane B flies too short and Airplane C takes too long. For example: Airplane A meets all criteria with strong performance in both distance and time. Choice C represents focusing on one criterion while ignoring others. Students who choose this may think the farthest flying distance is automatically best without checking the time constraint. To help students: Create a comparison checklist or table with solutions as rows and criteria as columns, marking yes/no or scores for each. Ask "Does Solution A meet Criterion 1? Criterion 2? Criterion 3?" for each solution. Emphasize that "best" means meeting the most criteria or all criteria, not just being good at one thing. Practice identifying when a solution excels in one area but fails in another (trade-offs). Use sentence frame: "[Solution X] is best because it meets [criteria Y and Z] by [evidence]."
- Maya tested 3 plant containers for growing beans. Criteria: costs $2 or less, plants grow 7+ inches, and water drains well. Look at the results and compare. Which container best meets the criteria?
Answer: Milk carton because it is $0, grew 9 inches, and drains well
This question tests comparing solutions using criteria (NGSS 3-5-ETS1-2: Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem). Comparing solutions means evaluating how well each option meets the criteria for success. Engineers use data and evidence to compare solutions systematically rather than just picking their favorite. In this scenario, students must compare 3 plant containers: plastic cup, clay pot, and milk carton. The criteria for success are costs $2 or less, plants grow 7+ inches, and water drains well. Looking at the data: plastic cup is free with 6-inch growth, clay pot costs unknown with 8-inch growth and good drainage, milk carton is $0 with 9-inch growth and good drainage. Choice C is correct because the milk carton meets all three criteria: it costs $0 (under $2 limit), plants grew 9 inches (more than 7-inch minimum), and it drains well, making it the best solution based on the evidence provided. Choice A represents focusing on cost while ignoring growth criteria. Students who choose this may think free is always best without checking that 6 inches fails the 7+ inch growth requirement. To help students: Create a comparison checklist with containers as rows and criteria as columns, marking yes/no for each. Ask "Does the plastic cup meet the cost criterion? Growth criterion? Drainage criterion?" for each container. Use sentence frame: "The milk carton is best because it meets all criteria by costing $0, growing 9 inches, and draining well."
- Maya wants the best way to pack snacks. Criteria: keeps snacks separate, uses few containers, and takes under 12 minutes. Method A uses 20 bags, keeps separate, and takes 15 minutes. Method B uses 1 container with dividers, keeps separate, and takes 10 minutes. Method C uses 1 bag, snacks mix, and takes 2 minutes. Which method best meets the criteria?
Answer: Method B because it keeps snacks separate, uses 1 container, and takes 10 minutes

Comparing solutions means evaluating how well each option meets the criteria for success. Sometimes comparing solutions reveals trade-offs - one solution is faster but less effective, another is slower but more effective - and engineers must decide which factors matter most. In this scenario, students must compare 3 snack packing methods: Method A, Method B, and Method C. The criteria for success are keeps snacks separate, uses few containers, and takes under 12 minutes. Looking at the data: Method A keeps separate (meets criteria), uses 20 bags (fails criteria - not few), takes 15 minutes (fails criteria); Method B keeps separate (meets criteria), uses 1 container with dividers (meets criteria), takes 10 minutes (meets criteria); Method C uses 1 bag (meets criteria), snacks mix (fails criteria), takes 2 minutes (meets criteria). Choice C is correct because Method B is the only method that meets all three criteria: it keeps snacks separate using dividers, uses only 1 container (few), and takes 10 minutes (under 12-minute limit). Choice A represents choosing the fastest method while ignoring quality requirements. Students who choose this may think speed is most important without checking if the method actually keeps snacks separate as required. To help students: Create a comparison checklist or table with solutions as rows and criteria as columns, marking yes/no for each. Ask "Does Method A keep snacks separate? Use few containers? Take under 12 minutes?" for each method. Practice identifying when a solution is fast but ineffective versus slower but successful. Use sentence frame: "Method B is best because it meets all criteria by keeping snacks separate, using 1 container, and taking 10 minutes."
- Yuki tested 3 plant containers. Pot A costs $2, plants grew 7 inches, and it drains well. Pot B costs $1, plants grew 6 inches, and it drains well. Pot C costs $0, plants grew 8 inches, but water pooled. Criteria: costs $2 or less, grows 7+ inches, and drains well. Which container meets all the criteria?
Answer: Pot A because it costs $2, grew 7 inches, and drains well
This question tests comparing solutions using criteria (NGSS 3-5-ETS1-2: Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem). Comparing solutions means evaluating how well each option meets the criteria for success. Engineers must verify that solutions meet ALL criteria, even when another option performs better in individual areas. In this scenario, students must compare 3 plant containers: Pot A, Pot B, and Pot C. The criteria for success are costs $2 or less, grows 7+ inches, and drains well. Looking at the data: Pot A costs $2 with 7-inch growth and good drainage, Pot B costs $1 with 6-inch growth and good drainage, Pot C costs $0 with 8-inch growth but water pools. Choice C is correct because Pot A meets all three criteria: it costs $2 (at the $2 limit), plants grew 7 inches (meets 7-inch minimum), and it drains well (no pooling), making it the only container satisfying all requirements. Choice A represents being attracted to free options while ignoring performance problems. Students who choose this may think free is always best without recognizing that water pooling fails the drainage criterion, which could harm plants. To help students: Create a comparison table with pots as rows and criteria as columns, checking each systematically. Teach that "drains well" means water doesn't pool, which is important for plant health. Use sentence frame: "Pot A is best because it meets all criteria by costing $2, growing 7 inches, and draining properly."
- Read about three book holder designs tested at school. Design 1 holds 6 books, costs $0, and does not tip. Design 2 holds 4 books, costs $3, and is very stable. Design 3 holds 8 books, costs $5, and tips easily. Criteria: holds 5+ books, costs under $4, and does not tip. According to the results, which solution should students choose?
Answer: Design 1 because it holds 6 books, costs $0, and does not tip.

Looking at the data: Design 1 holds 6 at $0 without tipping, Design 2 holds 4 at $3 with stability, Design 3 holds 8 at $5 and tips. To find the best solution, check which option meets all criteria or performs best overall. Choice B is correct because it selects Design 1, which holds 6 books (over 5), costs $0 (under $4), and does not tip, meeting all criteria while Design 2 holds too few and Design 3 costs too much and tips. For example: Design 1 fully satisfies the requirements. Choice C represents choosing based on one impressive feature without criteria justification. Students who choose this may pick the highest capacity but ignore cost and tipping issues. To help students: Create a comparison checklist or table with solutions as rows and criteria as columns, marking yes/no or scores for each. Ask "Does Solution A meet Criterion 1? Criterion 2?

Comparing solutions means evaluating how well each option meets the criteria for success. When multiple criteria exist (like cost, performance, and drainage), the best solution meets ALL criteria, not just one or two. In this scenario, students must compare 3 container options for growing bean plants. The criteria for success are: costs $2 or less, plants grow 7+ inches, AND drains water well. Looking at the data: Clay pot costs $4 (fails), grows 8 inches (meets), drains well (meets); Plastic cup costs $0 (meets), grows 6 inches (fails), water pools (fails); Milk carton costs $0 (meets), grows 9 inches (meets), drains well (meets). Choice C is correct because the milk carton meets all three criteria: it's free (under $2), plants grew 9 inches (more than 7), and it drains well, making it the only solution that satisfies every requirement. Choice B represents focusing on partial success while ignoring failures. Students who choose this may see that the clay pot performs well in two areas (growth and drainage) without recognizing that failing the cost criterion disqualifies it. To help students: Create a comparison table with solutions as rows and criteria as columns, marking pass/fail for each.

Comparing solutions means evaluating how well each option meets the criteria for success. When multiple criteria exist, the best solution meets ALL criteria, not just one. Sometimes comparing solutions reveals trade-offs between performance and time efficiency. In this scenario, students must compare 3 paper airplanes: Plane A, Plane B, and Plane C. The criteria for success are fly 15+ feet and fold in under 10 minutes. Looking at the data: Plane A (16 feet, 9 minutes), Plane B (20 feet, 11 minutes), Plane C (14 feet, 5 minutes). Choice C is correct because Plane A is the only one that meets both criteria: it flew 16 feet (more than 15 minimum) and took 9 minutes to fold (under 10 minute limit), while Plane B exceeds the time limit and Plane C fails the distance requirement. Choice A represents focusing on one criterion while ignoring others. Students who choose this may think the farthest flying plane is automatically best without checking that 11 minutes exceeds the 10 minute time limit. To help students: Create a comparison checklist or table with solutions as rows and criteria as columns, marking yes/no or scores for each. Ask "Does Plane A meet the distance criterion?

Comparing solutions means evaluating how well each option meets the criteria for success. Engineers must systematically check all criteria rather than assuming one good feature makes up for failures. In this scenario, students must compare 3 snack-packing methods. The criteria for success are: snacks stay separate, use few containers, AND take under 12 minutes. Looking at the data: Method A keeps snacks separate (meets), uses 20 bags (fails - not few), takes 15 minutes (fails); Method B keeps snacks separate (meets), uses 1 container (meets - few), takes 10 minutes (meets); Method C uses 1 bag (meets - few), takes 2 minutes (meets), but snacks get mixed (fails separation). Choice A is correct because Method B meets all three criteria: it keeps snacks separate, uses only 1 container (few), and takes 10 minutes (under 12), making it the only solution that satisfies every requirement. Choice C represents prioritizing speed over essential requirements. Students who choose this may think the fastest method (2 minutes) is automatically best without recognizing that mixed snacks fail the primary criterion of keeping them separate. To help students: Create a comparison checklist systematically evaluating each criterion. Ask "Which is more important: saving 8 minutes or keeping snacks separate as required?" Use sentence frame: "Method B is best because it meets all criteria: separate snacks, 1 container, and 10 minutes."
- Read about the different designs tested. A class needs hamster bedding that absorbs smell 7+ out of 10, costs under $7, and is comfortable. Wood shavings absorb 9/10 and cost $8. Paper bedding absorbs 6/10 and costs $6. Shredded paper absorbs 3/10 and costs $0. Which solution meets all the criteria for success?
Answer: None of the bedding choices because each fails at least 1 rule.

Sometimes comparing solutions reveals trade-offs - one solution is faster but more expensive, another is cheaper but slower - and engineers must decide which factors matter most. In this scenario, students must compare three solutions: wood shavings, paper bedding, and shredded paper. The criteria for success are absorbs smell 7+ out of 10, costs under $7, and is comfortable. Looking at the data: wood shavings absorb 9/10 but cost $8; paper bedding absorbs 6/10, costs $6; shredded paper absorbs 3/10, costs $0. To find the best solution, check which option meets all criteria or performs best overall. Choice D is correct because none meet all criteria: each fails at least one, such as wood shavings cost too much, paper bedding absorbs too little, and shredded paper absorbs too little. For example: no solution satisfies all three while others fail key aspects like absorption or cost. This solution best meets the stated criteria based on the evidence provided. Choice A represents focusing on one criterion while ignoring others. Students who choose this may look at one impressive number without checking if ALL criteria are met. To help students: Create a comparison checklist or table with solutions as rows and criteria as columns, marking yes/no or scores for each. Ask "Does Solution A meet Criterion 1? Criterion 2? Criterion 3?" for each solution. Emphasize that "best" means meeting the most criteria or all criteria, not just being good at one thing.

- Amir tested 3 bedding materials for a class hamster. Wood shavings: smell rating 9/10, costs $8, soft. Paper bedding: smell rating 6/10, costs $6, very soft. Shredded paper: smell rating 3/10, costs $0, somewhat soft. Criteria: smell rating 7+, costs under $7, and comfortable. Which bedding should Amir choose?
Answer: None of them because no choice has rating 7+ and costs under $7
This question tests comparing solutions using criteria (NGSS 3-5-ETS1-2: Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem). Comparing solutions means evaluating how well each option meets the criteria for success. Sometimes no solution meets all criteria, requiring engineers to recognize when more work is needed. In this scenario, students must compare 3 bedding materials: wood shavings, paper bedding, and shredded paper. The criteria for success are smell rating 7+, costs under $7, and comfortable. Looking at the data: Wood shavings have 9/10 smell rating but cost $8, paper bedding has 6/10 smell rating and costs $6, shredded paper has 3/10 smell rating and costs $0. Choice D is correct because none of the options meet all criteria: wood shavings exceed the cost limit ($8 > $7), paper bedding fails the smell rating (6/10 < 7), and shredded paper also fails the smell rating (3/10 < 7). Choice B represents focusing on one strong feature while ignoring cost constraints. Students who choose this may see the excellent smell rating without checking that $8 exceeds the $7 budget limit. To help students: Create a comparison checklist and systematically check each option against ALL criteria. Teach students that sometimes the answer is "none meet all criteria" and more solutions need to be explored. Use sentence frame: "No bedding meets all criteria because each fails at least one requirement."
- Students compared 3 snack packing methods for a field trip. Method A uses 20 bags, keeps snacks separate, and takes 15 minutes. Method B uses 1 container, keeps snacks separate, and takes 10 minutes. Method C uses 1 bag, snacks get mixed, and takes 2 minutes. Criteria: keeps snacks separate, uses few containers, and takes under 12 minutes. Which solution should students choose?
Answer: Method B because it stays separate, uses 1 container, and takes 10 minutes.
This question tests comparing solutions using criteria (NGSS 3-5-ETS1-2: Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem). Comparing solutions means evaluating how well each option meets the criteria for success. When multiple criteria exist, engineers must find solutions that satisfy all requirements, not just optimize for one factor like speed. In this scenario, students must compare 3 snack packing methods: Method A (20 bags, separate, 15 minutes), Method B (1 container, separate, 10 minutes), and Method C (1 bag, mixed, 2 minutes). The criteria for success are keeps snacks separate, uses few containers, and takes under 12 minutes. Looking at the data: Method A fails container count (20 is not few) and time (15 > 12), Method B meets all criteria (separate, 1 container is few, 10 < 12), Method C fails separation requirement. Choice C is correct because Method B meets all three criteria: it keeps snacks separate (meets quality requirement), uses only 1 container (meets efficiency goal), and takes 10 minutes (under 12-minute limit). Choice A represents focusing on the fastest solution while ignoring quality requirements - students who choose this may think speed is most important without realizing that mixed snacks fail the separation criterion. To help students: Create a comparison table marking yes/no for each criterion. Practice identifying trade-offs between speed and quality. Use sentence frame: "Method B is best because it meets separation, container, and time criteria by keeping snacks separate in 1 container within 10 minutes."
- Read about the different designs tested. Students want a paper airplane that flies at least 15 feet and folds in under 10 minutes. Plane A flew 16 feet and took 9 minutes. Plane B flew 20 feet and took 11 minutes. Plane C flew 14 feet and took 5 minutes. Which solution best meets the need while following the constraints?
Answer: Plane A because it flew 16 feet and took 9 minutes to fold.
This question tests comparing solutions using criteria (NGSS 3-5-ETS1-2: Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem). Comparing solutions means evaluating how well each option meets the criteria for success. Engineers use data and evidence to compare solutions systematically rather than just picking their favorite. When multiple criteria exist (like cost, performance, and time), the best solution meets ALL or MOST criteria, not just one. Sometimes comparing solutions reveals trade-offs - one solution is faster but more expensive, another is cheaper but slower - and engineers must decide which factors matter most. In this scenario, students must compare three solutions: Plane A, Plane B, and Plane C. The criteria for success are flies at least 15 feet and folds in under 10 minutes. Looking at the data: Plane A flew 16 feet in 9 minutes; Plane B flew 20 feet in 11 minutes; Plane C flew 14 feet in 5 minutes. To find the best solution, check which option meets all criteria or performs best overall. Choice C is correct because Plane A is best: it meets both criteria with 16 feet (more than 15) and 9 minutes (under 10). For example: Plane A meets both criteria while Plane B takes too long to fold and Plane C doesn't fly far enough. This solution best meets the stated criteria based on the evidence provided. Choice A represents focusing on one criterion while ignoring others. Students who choose this may think the farthest flying is automatically best without checking the time constraint. To help students: Create a comparison checklist or table with solutions as rows and criteria as columns, marking yes/no or scores for each. Ask "Does Solution A meet Criterion 1? Criterion 2? Criterion 3?" for each solution. Emphasize that "best" means meeting the most criteria or all criteria, not just being good at one thing. Practice identifying when a solution excels in one area but fails in another (trade-offs). Use sentence frame: "[Solution X] is best because it meets [criteria Y and Z] by [evidence]."
- Keisha tested 3 water bottle holders for a bike ride. Holder 1 is secure, fits in a backpack pocket, and costs $0. Holder 2 is secure, does not fit, and costs $8. Holder 3 fits and costs $2, but the bottle slides out sometimes. Criteria: holds securely, fits in backpack, costs under $5. Which holder meets all the criteria?
Answer: Holder 1 because it is secure, fits, and costs $0
This question tests comparing solutions using criteria (NGSS 3-5-ETS1-2: Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem). Comparing solutions means evaluating how well each option meets the criteria for success. Engineers use data to find solutions that satisfy all requirements, not just some. In this scenario, students must compare 3 water bottle holders: Holder 1, Holder 2, and Holder 3. The criteria for success are holds securely, fits in backpack, and costs under $5. Looking at the data: Holder 1 is secure, fits, costs $0; Holder 2 is secure but doesn't fit, costs $8; Holder 3 fits, costs $2, but bottle slides out. Choice C is correct because Holder 1 meets all three criteria: it holds securely (stable), fits in the backpack pocket (portable), and costs $0 (under $5 limit), making it the perfect solution. Choice A represents valuing one criterion while ignoring practical constraints. Students who choose this may think secure holding is most important without checking that Holder 2 doesn't fit in the backpack and costs too much. To help students: Create a comparison table with holders as rows and criteria as columns, marking yes/no for each. Emphasize that all criteria matter equally - a secure holder that doesn't fit is useless for the intended purpose. Use sentence frame: "Holder 1 is best because it meets all criteria by holding securely, fitting in the backpack, and costing $0."
- Amir is choosing bedding for a class hamster. Criteria: smell rating 7+ out of 10, costs under $7 per month, and is comfortable. Wood shavings: 9/10, $8, soft. Paper bedding: 6/10, $6, very soft. Shredded paper: 3/10, $0, somewhat soft. Which bedding best meets the criteria?
Answer: None of them because no option is 7+ and under $7
This question tests comparing solutions using criteria (NGSS 3-5-ETS1-2: Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem). Comparing solutions means evaluating how well each option meets the criteria for success. When multiple criteria exist, the best solution meets ALL criteria, and sometimes no solution meets all requirements. In this scenario, students must compare 3 hamster bedding options: Wood shavings, Paper bedding, and Shredded paper. The criteria for success are smell rating 7+ out of 10, costs under $7 per month, and is comfortable. Looking at the data: Wood shavings rate 9/10 (meets criteria), cost $8 (fails criteria), soft (meets criteria); Paper bedding rates 6/10 (fails criteria), costs $6 (meets criteria), very soft (meets criteria); Shredded paper rates 3/10 (fails criteria), costs $0 (meets criteria), somewhat soft (meets criteria). Choice D is correct because none of the options meet all three criteria: Wood shavings fail the cost requirement ($8 exceeds $7 limit), Paper bedding fails the smell rating (6/10 is below 7+ requirement), and Shredded paper fails the smell rating (3/10 is well below 7+ requirement). Choice A represents focusing on one high-performing criterion while ignoring a failure. Students who choose this may think the excellent smell rating of wood shavings justifies exceeding the budget constraint. To help students: Create a comparison checklist or table with solutions as rows and criteria as columns, marking yes/no for each. Ask "Does each bedding option meet ALL three criteria?" Teach students that sometimes the answer is "none of the above" when no solution fully works. Use sentence frame: "None of the options work because each fails at least one criterion."
