All questions
Question 1
Sofia wanted the ball to roll farther. No ramp: 3 tiles. With ramp: 8 tiles. Did the ramp work?
- No, it didn't work. It rolled 3 tiles.
- Yes, it worked. It rolled 8 tiles. (correct answer)
- Yes, it worked because Sofia tried hard.
Explanation: This tests comparing numbers. The ball rolled more tiles with the ramp (8 is more than 3). The ramp helped the ball go farther!
Question 2
Yuki wanted to push a far ball. Hand: couldn't reach. Long stick: pushed the ball. Did the stick work?
- Yes, it worked because she could reach. (correct answer)
- No, it didn't work because the ball is round.
- No, it didn't work because she used a stick.
Explanation: This tests using tools. Yuki couldn't reach with her hand. The long stick helped her push the ball. The stick solved her problem.
Question 3
Sofia wanted the ball to go left. She pushed it forward, it hit a barrier, and went left. Did the barrier work?
- No, it didn't work because it hit something.
- Yes, it worked because it went left. (correct answer)
- Yes, it worked because Sofia pushed hard.
Explanation: This checks if the barrier worked. Sofia wanted the ball to go left. The barrier made it turn left. Her design worked!
Question 4
Keisha wanted the car to stop faster. Hard floor: stopped after 10 tiles. Soft mat: stopped after 2 tiles. Did it work?
- No, it didn't work because it went 10 tiles.
- Yes, it worked because it stopped in 2 tiles. (correct answer)
- No, it didn't work because the mat is big.
Explanation: This tests if the mat worked. Keisha wanted the car to stop fast. It stopped in 2 tiles on the mat. The soft mat worked!
Question 5
Amir wanted the ball to go left. He added a barrier, but the ball went straight. Did the barrier work?
- No, it didn't work. It went straight. (correct answer)
- Yes, it worked. A barrier was there.
- Yes, it worked. Amir pushed the ball.
Explanation: This tests if a design worked. Amir wanted the ball to go left, but it went straight. The barrier did not work!
Question 6
Carlos wanted the wagon to move easier. Pushing: too heavy, barely moved. Pulling with rope: moved easily. Did rope work?
- No, it didn't work because the wagon had blocks.
- Yes, it worked because pulling moved it easily. (correct answer)
- Yes, it worked because ropes are long.
- No, it didn't work because Carlos tried twice.
Explanation: This question tests kindergarten understanding of analyzing test results to determine if a design solution worked as intended (K-PS2-2: Analyze data to determine if design solution works to change speed or direction). A design works if it achieves the goal we set. First, we state our goal (make object go farther, change direction, move easier). Then we test the design and observe results. Finally, we compare: Did what happened match what we wanted? If yes, design worked. If no, design didn't work. We use evidence (distance traveled, direction taken, ease of movement) to decide. In this test, the goal was to make the wagon move easier. Carlos tested pulling with a rope. The results show: too heavy and barely moved when pushing versus moved easily when pulling. This matches the goal. Choice B is correct because it accurately determines design effectiveness by comparing goal to result. The goal was to move easier, the result was easy movement, and they match, so the design worked. The answer uses evidence: pulling moved it easily shows achievement of the goal. Choice A is incorrect because it says didn't work when results show it did by focusing on unrelated details like blocks. Kindergarteners often focus on tool use instead of result or don't recognize partial success vs complete success. To help students: Make goal-setting explicit: 'Our goal is to make the ball roll at least 10 tiles.' Test the design and record results clearly: 'With ramp, ball rolled 12 tiles.' Guide comparison: 'Our goal was 10 tiles. We got 12 tiles. Did we reach our goal? Yes! Design worked.' Use three-part framework: Goal → Test → Compare. Show both successful and unsuccessful designs so students practice analyzing both. Use visual cues: smiley face when goal met, sad face when not met. Emphasize evidence-based decision making: 'How do we know? Look at the results.' Practice with clear-cut examples before ambiguous ones. Watch for: students who don't explicitly compare goal to result, those who describe tool without assessing effectiveness, or those who guess without looking at evidence. Make goals measurable and observable (go 5 tiles, change to go left, move heavy box 3 steps) so students can clearly see success or failure.
Question 7
Chen wanted the ball to go left. He added a barrier. The ball hit it and went left. Did the barrier work?
- No, it didn't work because it went left.
- Yes, it worked because the ball went left. (correct answer)
- Yes, it worked because the barrier was tall.
Explanation: This tests if a design worked. Chen wanted the ball to go left. The barrier made it go left. The barrier did what Chen wanted.
Question 8
Jamal wanted the box to move easier. No wheels: hard, barely moved. With wheels: easy, moved smoothly. Did wheels work?
- Yes, wheels worked. It moved smoothly. (correct answer)
- No, wheels didn't work. It still moved.
- Yes, wheels worked because the box is big.
Explanation: This tests if a design worked. The wheels made moving easy and smooth. That means the wheels worked!
Question 9
Maya wanted to push a far ball. Hand couldn't reach. Long stick reached and pushed the ball. Did the stick work?
- Yes, it worked because it reached the ball. (correct answer)
- No, it didn't work because hands are better.
- No, it didn't work because the ball is round.
Explanation: This tests if the tool helped. Maya's hand couldn't reach the ball. The long stick reached and pushed it. The stick worked!
Question 10
Emma wanted the ball to roll farther. No ramp: 3 tiles. Ramp: 8 tiles. Did the ramp work?
- No, it didn't work because it rolled.
- Yes, it worked because it went 8 tiles. (correct answer)
- No, it didn't work because ramps are hard.
Explanation: This tests if the design worked. The ramp made the ball go farther. It went from 3 tiles to 8 tiles. The ramp worked great!
Question 11
Sofia wanted the ball to go left. She added a barrier. The ball hit it and went left. Did it work?
- No, it didn't work because it hit something.
- Yes, it worked because it went left. (correct answer)
- Yes, it worked because the barrier was tall.
- No, it didn't work because it rolled forward.
Explanation: This question tests kindergarten understanding of analyzing test results to determine if a design solution worked as intended (K-PS2-2: Analyze data to determine if design solution works to change speed or direction). A design works if it achieves the goal we set. First, we state our goal (make object go farther, change direction, move easier). Then we test the design and observe results. Finally, we compare: Did what happened match what we wanted? If yes, design worked. If no, design didn't work. We use evidence (distance traveled, direction taken, ease of movement) to decide. In this test, the goal was to make the ball go left. Sofia tested a barrier. The results show: the ball hit the barrier and went left. This matches the goal. Choice B is correct because it accurately determines design effectiveness by comparing goal to result. The goal was to go left, the result was going left, and they match, so the design worked. The answer uses evidence: going left after hitting shows achievement of the goal. Choice A is incorrect because it says didn't work when results show it did by focusing on hitting instead of the direction change. Kindergarteners often ignore goal and just describe what happened or think using a design means it worked. To help students: Make goal-setting explicit: 'Our goal is to make the ball roll at least 10 tiles.' Test the design and record results clearly: 'With ramp, ball rolled 12 tiles.' Guide comparison: 'Our goal was 10 tiles. We got 12 tiles. Did we reach our goal? Yes! Design worked.' Use three-part framework: Goal → Test → Compare.

Question 12
Marcus wanted the ball to go left. He put a barrier, but the ball went straight. Did the barrier work?
- Yes, it worked because the ball moved.
- No, it didn't work because it went straight. (correct answer)
- Yes, it worked because the barrier was big.
- No, it didn't work because Marcus used a barrier.
Explanation: This question tests kindergarten understanding of analyzing test results to determine if a design solution worked as intended (K-PS2-2: Analyze data to determine if design solution works to change speed or direction). A design works if it achieves the goal we set. First, we state our goal (make object go farther, change direction, move easier). Then we test the design and observe results. Finally, we compare: Did what happened match what we wanted? If yes, design worked. If no, design didn't work. We use evidence (distance traveled, direction taken, ease of movement) to decide. In this test, the goal was to make the ball go left. Marcus tested a barrier. The results show: the ball went straight despite the barrier. This doesn't match the goal. Choice B is correct because it accurately determines design effectiveness by comparing goal to result. The goal was to go left, the result was going straight, and they don't match, so the design didn't work. The answer uses evidence: going straight shows non-achievement of changing direction. Choice A is incorrect because it says worked when results show it didn't by ignoring the specific direction goal. Kindergarteners often describe what happened without comparing to goal or focus on trying hard instead of achieving goal. To help students: Make goal-setting explicit: 'Our goal is to make the ball roll at least 10 tiles.' Test the design and record results clearly: 'With ramp, ball rolled 12 tiles.' Guide comparison: 'Our goal was 10 tiles. We got 12 tiles. Did we reach our goal? Yes! Design worked.' Use three-part framework: Goal → Test → Compare.

Question 13
Keisha wanted the toy to slide farther. Bumpy floor: stopped quickly. Smooth floor: slid far. Did the smooth path work?
- Yes, it worked. It slid far on smooth. (correct answer)
- No, it didn't work. It stopped quickly.
- No, it didn't work because it is small.
Explanation: This tests if a design worked. The toy slid far on the smooth floor. Smooth paths help things slide!
Question 14
Carlos wanted to move a heavy wagon. Pushing behind: barely moved. Pulling with a rope: moved easily. Did the rope work?
- No, it didn't work. Wagons are heavy.
- Yes, it worked. The wagon moved easily. (correct answer)
- Yes, it worked because he used a tool.
Explanation: This tests if a design worked. The rope made the wagon move easily. Pulling with rope worked better than pushing!
Question 15
Chen wanted the ball to go left. He pushed it forward; it hit a barrier and went left. Did the barrier work?
- No, it didn't work. The ball moved.
- Yes, it worked. The ball went left. (correct answer)
- No, it didn't work because Chen pushed it.
Explanation: This tests if a design worked. Chen wanted the ball to go left, and it did! The barrier changed where the ball went.
Question 16
Maya wanted the toy car to stop fast. Hard floor: rolled far. Soft mat: stopped quickly. Did the mat work?
- Yes, it worked. The car stopped quickly. (correct answer)
- No, it didn't work. The car rolled far.
- Yes, it worked because the mat is soft.
Explanation: This tests if a design worked. Maya wanted the car to stop fast. The soft mat made it stop quickly!
Question 17
Amir wanted to move a heavy box. One child pushed: it didn't move. Two children pushed: it moved forward. Did it work?
- No, it didn't work because it was heavy.
- Yes, it worked because two kids pushed. (correct answer)
- No, it didn't work because they tried.
Explanation: This asks about teamwork helping. One child couldn't move the box. Two children pushed and it moved. Working together worked!
Question 18
Sofia wanted the ball to roll farther. No ramp: 3 tiles. Ramp: 8 tiles. Did the ramp work?
- No, it didn't work because it rolled less.
- Yes, it worked because it rolled farther. (correct answer)
- Yes, it worked because Sofia used a ramp.
Explanation: This tests comparing results. The ball rolled 8 tiles with the ramp but only 3 tiles without it. Since 8 is more than 3, the ramp helped the ball go farther.
Question 19
Carlos wanted to move a wagon of blocks. Pushing: barely moved. Pulling with rope: moved easily. Did the rope work?
- No, it didn't work because wagons are heavy.
- Yes, it worked because it moved easily. (correct answer)
- Yes, it worked because ropes are long.
Explanation: This tests push versus pull. Pushing the wagon was hard. Pulling with rope made it easy. The rope helped Carlos move it.
Question 20
Amir wanted to move a heavy box. One child pushed: box didn't move. Two children pushed: box moved forward. Did it work?
- No, it didn't work because one child pushed.
- Yes, it worked because the box moved forward. (correct answer)
- Yes, it worked because pushing is always enough.
Explanation: This tests force and teamwork. One child couldn't move the box. Two children pushed together and moved it. Working together made it work.
