This question tests 4th grade ability to ask scientific questions about energy changes during collisions (NGSS 4-PS3-3). Students must identify questions that are specific, testable, and focused on observable motion or energy changes. Good scientific questions about collisions: (1) are specific about what to observe (speed, direction, motion of specific objects), (2) can be answered by observing the collision, (3) focus on motion or energy changes, (4) are testable through investigation. Poor questions are not about energy/motion ("Why are marbles shiny?"), subjective ("prettiest pattern"), or already answered ("Are marbles still?" - yes, as stated). In this collision where one marble hits three still marbles and two roll away, good questions would ask about: how changing the number of still marbles affects outcomes, why two marbles moved instead of all three, how energy divides among marbles, or what determines which marbles move. These questions can be answered by testing and observing, directly relating to motion and energy changes. Choice B is correct because it asks a specific, testable question about how changing the number of still marbles affects how many move after collision. This question can be answered by testing with different numbers of marbles, focuses on the relationship between setup and motion outcomes, and helps understand energy transfer patterns. This demonstrates good scientific questioning - identifying variables that affect results. Choice D is incorrect because "Are the marbles sitting still before Keisha rolls one?" is already answered in the problem statement which says "three still marbles." This is a weak scientific question because the answer is already given, it doesn't investigate energy changes, and doesn't guide investigation. Good questions explore unknowns, not confirm given information. To help students ask good questions: Model the process - before demonstrations, brainstorm: 'What could we observe? What might change? What would we measure?' Practice turning vague questions into specific ones: 'What happens?' becomes 'How does marble number affect movement?' Emphasize observable, measurable changes. Use question stems: 'How will ___ change?' 'What will happen to ___?' 'How does ___ affect ___?' Create T-chart: Good Questions vs. Poor Questions with examples. Remind: Good questions are specific (name what to observe), observable (can see/measure), and about energy/motion changes in this scenario.

In this collision between falling dominoes in a line on a desk, good questions would ask about: how one domino's motion causes the next to move, chain reactions in speed or direction, how far the effect travels, or motion transfer. These questions can be answered by carefully observing before and after the collision and are directly about motion and energy changes. Choice A is correct because it asks a specific, testable question about how the falling domino’s motion causes the next domino to start moving. This question can be answered by observing the dominoes' falling sequence during collisions, focuses on observable motion or energy changes, and helps understand what happens during collisions. This demonstrates good scientific questioning skills - being specific about what to investigate. Choice D is incorrect because it is too vague and doesn't specify the observable outcome. This is a weak scientific question because it isn't testable with details and doesn't focus on energy transfer; it's overly general.
