This question tests 4th grade ability to trace energy transfer pathways, identifying where energy starts, where it goes, and where it ends (NGSS 4-PS3-2). Students must understand that energy follows a path from source to destination. An energy transfer pathway shows the route energy takes as it moves. Every pathway has three parts: (1) a SOURCE where energy starts, (2) INTERMEDIATE STEPS where energy passes through or transfers, and (3) a DESTINATION where energy ends up or is used. Energy doesn't just appear—it always comes from somewhere and travels to somewhere. In this scenario, the energy pathway is: battery → wires → switch → bulb → light; the SOURCE is the battery, it transfers through wires and switch to the bulb, and the DESTINATION is the light given off by the bulb. For example: the battery is the source, electrical energy travels through wires and the closed switch, reaches the bulb, and converts to light energy. Choice A is correct because it shows the complete pathway in the right order, starting from the battery and ending with light, matching the scenario where energy flows after the switch is flipped. Choice B is incorrect because it starts with the switch instead of the battery, scrambling the order. This error often happens when students confuse the action of flipping the switch with the energy source or trace object movement instead of energy flow. To help students trace pathways: Draw energy pathways with arrows showing direction (source → step 1 → step 2 → destination). Use consistent language: 'Where does it START? Where does it GO? Where does it END?' Practice with familiar examples, then more complex chains. Act out pathways physically (one student is battery, one is wires, one is switch, one is bulb—pass 'energy' object along chain). Key skill: Following the path step by step from beginning to end.

Every pathway has three parts: (1) a SOURCE where energy starts, (2) INTERMEDIATE STEPS where energy passes through or transfers, and (3) a DESTINATION where energy ends up or is used. Energy doesn't just appear—it always comes from somewhere and travels to somewhere. In this scenario, the energy pathway is: battery → bulb → light to mirror → light to wall; the SOURCE is the battery, it transfers through the bulb and mirror, and the DESTINATION is the wall. For example: the battery is the source, electrical energy converts to light at the bulb, light travels to hit the mirror, reflects, and reaches the wall—the destination. Choice C is correct because it correctly identifies the destination as the wall, where the light energy finally ends up after reflecting. Choice A is incorrect because it identifies the wrong ending point as the battery, which is actually the source. This error often happens when students reverse the pathway or don't realize intermediate steps matter. To help students trace pathways: Draw energy pathways with arrows showing direction (source → step 1 → step 2 → destination). Use consistent language: 'Where does it START? Where does it GO? Where does it END?' Practice with familiar examples, then more complex chains.

In this scenario, the energy pathway is: Carlos’s voice → electric signal → wires → other phone sound; the SOURCE is Carlos’s voice, it transfers as electric signal through wires, and the DESTINATION is the sound from the other phone. For example: Carlos’s voice is the source, converts to electric signal in the phone, travels through wires, and becomes sound at Keisha’s phone—the destination. Choice B is correct because it shows the complete pathway in the right order, from voice to final sound. Choice C is incorrect because it reverses the pathway, starting from the other phone sound. This error often happens when students think energy can go backwards or scramble the order. To help students trace pathways: Draw energy pathways with arrows showing direction (source → step 1 → step 2 → destination). Use consistent language: 'Where does it START? Where does it GO? Where does it END?' Practice with familiar examples, then more complex chains.

In this scenario, the energy pathway is: sunlight → window → book → Yuki’s eyes; the SOURCE is sunlight, it transfers through the window to the book, and the DESTINATION is Yuki’s eyes after bouncing. For example: sunlight is the source, passes through the window, hits the book, and reflects into Yuki’s eyes—the destination. Choice B is correct because it correctly identifies the destination after the book as Yuki’s eyes, where the light energy goes next. Choice A is incorrect because it reverses the pathway back to the sun, which is the source. This error often happens when students think energy can go backwards or skip important steps. To help students trace pathways: Draw energy pathways with arrows showing direction (source → step 1 → step 2 → destination). Use consistent language: 'Where does it START? Where does it GO? Where does it END?' Practice with familiar examples, then more complex chains.

In this scenario, the energy pathway is: Sofia’s voice → sound through air → Chen’s ear; the SOURCE is Sofia’s voice, it transfers through the air, and the DESTINATION is Chen’s ear. For example: Sofia’s voice is the source, sound energy vibrates through the air, and reaches Chen’s ear—the destination where he hears it. Choice C is correct because it correctly identifies the source as Sofia’s voice, where the sound energy begins. Choice A is incorrect because it identifies the wrong starting point as Chen’s ear, which is the destination. This error often happens when students think energy can go backwards or confuse the medium like air with the source or destination. To help students trace pathways: Draw energy pathways with arrows showing direction (source → step 1 → step 2 → destination). Use consistent language: 'Where does it START? Where does it GO?

In this scenario, the energy pathway is: stove burner → pot → water → hot water; the SOURCE is the stove burner, it transfers through the pot to the water, and the DESTINATION is the hot water. For example: the stove burner is the source, heat conducts to the pot, then to the water, making it hot—the destination. Choice A is correct because it shows the complete pathway in the right order, matching the heat flow from burner to hot water. Choice D is incorrect because it reverses the pathway, starting from hot water and going backwards. This error often happens when students scramble the order or think energy can go backwards. To help students trace pathways: Draw energy pathways with arrows showing direction (source → step 1 → step 2 → destination). Use consistent language: 'Where does it START? Where does it GO?

In this scenario, the energy pathway is: wind → turbine → generator → wires → house lights; the SOURCE is the wind, it transfers through turbine, generator, and wires, and the DESTINATION is the house lights. For example: the wind is the source, kinetic energy turns the turbine, generates electricity, travels through wires, and powers the lights—the destination. Choice C is correct because it correctly identifies the source as the wind, where the energy chain begins.

In this scenario, the energy pathway is: voice → microphone → electrical signal → amplifier → speaker sound; the SOURCE is the voice, it transfers through microphone, signal, and amplifier, and the DESTINATION is the speaker sound. For example: Fatima’s voice is the source, converts at the microphone to electrical signal, strengthened by amplifier, and output as sound from speaker—the destination. Choice B is correct because it shows the complete pathway in the right order, from voice to speaker sound. Choice A is incorrect because it reverses the pathway, starting from the speaker.
