Which Design Works Better - Kindergarten Science

1. Test results: wide base stayed stable 5/5 bumps; narrow base stable 3/5. Which works better?
   Answer: Design 1 works better because it stayed stable 5/5 bumps, while Design 2 was stable 3/5 bumps. We are testing which stays steady. The wide base stayed up for all 5 bumps. The narrow base fell after 3 bumps. More bumps without falling is better.
2. Test data: Canopy covered 36 sq ft; umbrellas covered 18 sq ft. Which works better for shade?
   Answer: Design 1 works better because it covered 36 sq ft, and Design 2 covered 18 sq ft, so more shade. We compare numbers from tests. 36 square feet is bigger than 18. The canopy makes more shade. Big shade is better!
3. Test results: canopy shaded 36 sq ft; two umbrellas shaded 18 sq ft. Which works better?
   Answer: Design 1 works better because it shaded 36 sq ft, while Design 2 shaded 18 sq ft, so it covers more. We are looking at which gives more shade. The canopy made 36 square feet of shade. The umbrellas made only 18 square feet. More shade is better for staying cool.
4. Test results: L-shape held 5/5 books; wedge held 3/5. Which should we choose? Why?
   Answer: Choose Design 1 because it held 5/5 books, and Design 2 held 3/5, so Design 1 is steadier. We pick based on test results. Design 1 held all 5 books steady. Design 2 only held 3 books. Pick the one that holds more books.
5. Test results: long spout had 0 spills in 3 tries; short spout had 3 spills. Which works better?
   Answer: Design 1 works better because it had 0 spills in 3 tries, while Design 2 spilled 3 times. We are testing which waters without spilling. The long spout had zero spills. The short spout spilled every time. No spills means it works better.
6. Toy scoop test: Wide scoop 45 sec; narrow scoop 120 sec. For speed, which design is better?
   Answer: Design 1 is better for speed because it took 45 seconds, and Design 2 took 120 seconds to collect toys. We measure time to pick up. 45 seconds is faster than 120 seconds. Less time means quicker cleanup. Fast is better!
7. Test results: L-shape held 5/5 books; wedge held 3/5. Which should we pick? Use data.
   Answer: Design 1 works better because it held 5/5 books, and Design 2 held 3/5, so it meets the goal. We use test data to decide. L-shape held all 5 books. Wedge only held 3 books. Data shows L-shape wins!
8. Test results: deep basket 8/8 items; tray 5/8 items. Which design solves the problem better?
   Answer: Design 1 solves it better because it delivered 8/8 items, while Design 2 delivered 5/8, so none dropped. We want to deliver items safely. The deep basket kept all 8 items safe. The tray dropped 3 items. Zero drops solves the problem best.
9. Test results: long ramp reached the top; short ramp rolled back down. Which ramp works better?
   Answer: Design 1 works better because it reached the top, and Design 2 did not, so it solves the problem. We need to get the car to the top. The long ramp got the car all the way up. The short ramp let the car roll back. Only one solved the problem.
10. Carry 8 items without dropping. Test: Design 1 delivered 8/8; Design 2 delivered 5/8. Which works better?
    Answer: Design 1 works better because it delivered 8/8 items, but Design 2 delivered only 5/8 in the test. We are testing which carries items best. Design 1 carried all 8 items safely. Design 2 dropped 3 items. No drops is better!
11. Water high plants without spilling. Test: Design 1 had 0 spills/3; Design 2 had 3 spills/3. Which is better?
    Answer: Design 1 works better for high plants because it had 0 spills in 3 tests, while Design 2 spilled 3 times. We need to water plants without spilling. Design 1 had zero spills in all tests. Design 2 spilled every time. No spills is better!
12. Books must stay upright. Test: Design 1 held 5/5; Design 2 held 3/5. Which works better?
    Answer: Design 1 works better because test showed 5/5 books stayed up, but Design 2 only kept 3/5. We are comparing designs. Design 1 kept all 5 books up. Design 2 only kept 3 books up. More books staying up is better!
13. Ramp test: Long ramp reached top; short ramp rolled back. Which design solves the problem better?
    Answer: Design 1 works better because the car reached the top, and Design 2 failed and rolled back down. We test which ramp works. The long ramp got the car up. The short ramp made it roll back. Getting up is success!
14. Test results: two-step stool was easy and safe; one-step was hard. Which design works better?
    Answer: Design 1 works better because the child climbed easily and safely, but Design 2 was hard to climb. We need a safe stool for kids. The two-step stool was easy to climb. The one-step was too hard. Easy and safe is what works better.
15. Test results: L-shape held 5/5 books; wedge held 3/5. Which design works better?
    Answer: Design 1 works better because it held 5/5 books, and Design 2 held 3/5, so it is steadier. We look at test results. Design 1 held all 5 books. Design 2 only held 3 books. More books means better!
16. Help a child reach the sink safely. Test: Design 1 was easy and reached; Design 2 reached but was hard. Which better?
    Answer: Design 1 works better because the test showed easy climbing and reaching the sink, but Design 2 was hard to climb. We need safe sink reaching. Design 1 was easy and safe to climb. Design 2 was hard to climb. Easy and safe is better!
17. Test results: wide scoop 45 sec, misses under couch; narrow scoop 120 sec, reaches all. Which is better?
    Answer: Design 1 is better for speed because it took 45 seconds, but Design 2 is better to reach all toys. We have two different needs here. The wide scoop is fast but misses some toys. The narrow scoop is slow but gets all toys. Each is better for different jobs.
18. Test results: Basket delivered 8/8 items; tray delivered 5/8. Which design should we use? Why?
    Answer: Design 1 works better because it delivered 8/8 items, while Design 2 delivered 5/8, so it is reliable. We check which design works best. The basket carried all 8 items safely. The tray dropped 3 items. No drops is better!
19. Watering test for high plants: Long spout had 0/3 spills; short spout had 3/3 spills. Which works better?
    Answer: Design 1 works better because it had 0 spills in 3 trials, while Design 2 spilled 3 times in 3 trials. We count spills in our test. Long spout had zero spills. Short spout spilled every time. No spills means it works!
20. Test results: deep basket delivered 8/8 items; shallow tray delivered 5/8. Which design works better?
    Answer: Design 1 works better because it delivered 8/8 items, while Design 2 delivered 5/8, so fewer fell. We are testing which carries items safely. The deep basket kept all 8 items safe. The shallow tray dropped 3 items. No drops means it works better.
