All questions

Question 1

Chen reads by sunlight: Sun → through window → hits book → bounces to his eyes. Trace the energy pathway in order.

  1. Sun → book → window → Chen's eyes
  2. Sun → window → book → Chen's eyes (correct answer)
  3. Book → window → Sun → Chen's eyes
  4. Sun → Chen's eyes → window → book
Explanation: 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: Sun (SOURCE) → through window → hits book → bounces to Chen's eyes (DESTINATION). The SOURCE is the Sun producing light energy, it transfers through the window, reflects off the book, and the DESTINATION is Chen's eyes where he sees the reflected light. Choice B is correct because it shows the complete pathway in the right order: Sun first, then window, then book, finally eyes. This matches how light actually travels from its source through space and materials to reach our eyes. Choice A is incorrect because it places the book before the window, scrambling the order—light must pass through the window before it can hit the book. This error often happens when students don't think carefully about the physical path light takes through space. To help students trace pathways: Draw energy pathways with arrows showing direction (Sun → window → book → eyes). Use consistent language: 'Where does it START? Where does it GO? Where does it END?' Practice tracing light paths with flashlights and mirrors. Act out pathways physically (one student is Sun, one is window, one holds book, one is eyes—pass 'light beam' object along chain in correct order). Key skill: Following the path step by step in the correct sequence.

Question 2

Amir uses solar lights: Sun → solar panel → electric current → battery → LED. What is the source?

  1. The solar panel
  2. The sun (correct answer)
  3. The battery
  4. The LED light
Explanation: 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: Sun (source) → solar panel → electric current → battery → LED (destination). The SOURCE is the sun where light energy originates, it transfers through the solar panel which converts it to electricity, stores in the battery, and the DESTINATION is the LED where electrical energy becomes light. Choice B is correct because it correctly identifies the sun as the source—the original starting point where all energy in this system begins. This matches what happens in the scenario and shows the student can trace where energy comes from and where it goes. Choice A is incorrect because it identifies the solar panel as the source, but the panel is actually an intermediate step that converts energy from the sun. This error often happens when students confuse the device that captures energy with the actual source of energy. To help students trace pathways: Draw energy pathways with arrows showing direction (sun → panel → current → battery → LED). Use consistent language: 'Where does it START? Where does it GO? Where does it END?' Practice with familiar examples like solar calculators, then more complex chains. Act out pathways physically (one student is sun, one is panel, one is battery, one is LED—pass 'energy' object along chain). Key skill: Following the path step by step from beginning to end.

Question 3

Emma flips on a flashlight: battery → wires → bulb → light reaches her eyes. Where does the energy start?

  1. The battery (correct answer)
  2. Emma's eyes
  3. The bulb
  4. The wires
Explanation: 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 (SOURCE) → wires → bulb → light reaches Emma's eyes (DESTINATION). The SOURCE is the battery, it transfers through the wires to the bulb, and the DESTINATION is Emma's eyes where she sees the light. Choice A is correct because it correctly identifies the battery as the source—the starting point where chemical energy is stored and begins its journey through the circuit. Choice B is incorrect because it identifies Emma's eyes as the source, but eyes are actually the destination where light energy ends up, not where it starts. This error often happens when students confuse the end point with the starting point or trace the pathway backwards. To help students trace pathways: Draw energy pathways with arrows showing direction (battery → wires → bulb → eyes). Use consistent language: 'Where does it START? Where does it GO? Where does it END?' Practice with familiar examples like flashlights, then more complex chains. Act out pathways physically (one student is battery, one is wire, one is bulb, one is eyes—pass 'energy' object along chain). Key skill: Following the path step by step from beginning to end.

Question 4

Keisha makes a simple circuit: battery → wire → switch (on) → bulb lights. Where does the energy end up?

  1. At the switch
  2. At the bulb (correct answer)
  3. At the wire
  4. At the battery
Explanation: 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 (SOURCE) → wire → switch (on) → bulb lights (DESTINATION). The SOURCE is the battery storing chemical energy, it transfers through the wire and switch as electrical energy, and the DESTINATION is the bulb where electrical energy becomes light. Choice B is correct because it correctly identifies the bulb as the destination—the ending point where electrical energy is converted to light energy that we can see. Choice D is incorrect because it identifies the battery as the destination, but the battery is actually the source where energy starts, not where it ends up. This error often happens when students confuse the beginning and end of the pathway or don't understand that energy transforms at the destination. To help students trace pathways: Draw energy pathways with arrows showing direction (battery → wire → switch → bulb). Use consistent language: 'Where does it START? Where does it GO? Where does it END?' Practice with simple circuits, identifying transformations at each point. Act out pathways physically (one student is battery, one is wire, one is switch, one is bulb—pass 'electricity' object along chain and have bulb student light up). Key skill: Recognizing where energy transforms into its final useful form.

Question 5

Sofia reads: Sun → through window → hits book → bounces to eyes. Where does energy end up?

  1. At Sofia's eyes (correct answer)
  2. At the sun
  3. At the window
  4. At the book cover only
Explanation: 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: sun (source) → through window → hits book → bounces to eyes (destination). The SOURCE is the sun where light energy originates, it transfers through the window and bounces off the book, and the DESTINATION is Sofia's eyes where light energy is detected. Choice A is correct because it correctly identifies Sofia's eyes as the destination—the ending point where energy completes its journey and allows her to see. This matches what happens in the scenario and shows the student can trace where energy comes from and where it goes. Choice B is incorrect because it identifies the sun as the destination, but the sun is actually the source where light energy starts. This error often happens when students don't follow the complete pathway or confuse the brightest object with the destination. To help students trace pathways: Draw energy pathways with arrows showing direction (sun → window → book → eyes). Use consistent language: 'Where does it START? Where does it GO? Where does it END?' Practice with familiar examples like reading by sunlight, then more complex chains. Act out pathways physically (one student is sun, one is window, one is book, one is eyes—pass 'light energy' object along chain). Key skill: Following the path step by step from beginning to end.

Question 6

Maya warms her hands: campfire → heat through air → her hands feel warm. After leaving the fire, where does energy go?

  1. It goes into the air (correct answer)
  2. It goes back into the fire
  3. It goes into the ground first
  4. It goes straight to her hands, skipping air
Explanation: 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: campfire (SOURCE) → heat through air → Maya's hands (DESTINATION). The SOURCE is the campfire producing heat energy, it transfers through the air as heat radiation and convection, and the DESTINATION is Maya's hands where she feels warmth. Choice A is correct because it correctly identifies that after leaving the fire, energy goes into the air—this is the intermediate step where heat energy travels through space to reach Maya. Choice D is incorrect because it suggests energy goes straight to her hands, skipping air, but heat cannot travel through empty space without a medium or radiation path. This error often happens when students don't realize that energy needs a way to travel between source and destination. To help students trace pathways: Draw energy pathways with arrows showing direction (fire → air → hands). Use consistent language: 'Where does it START? Where does it GO? Where does it END?' Practice with heat examples like radiators, sun warmth, and hot food cooling. Act out pathways physically (one student is fire, several represent air carrying heat, one is hands receiving warmth). Key skill: Understanding that energy travels through intermediate steps, not magically jumping from source to destination.

Question 7

This scenario shows Emma warming her hands: campfire → heat through air → hands. Which correctly describes how energy moves?

  1. Campfire → hands → air
  2. Air → campfire → hands
  3. Campfire → heat through air → hands (correct answer)
  4. Hands → heat through air → campfire
Explanation: 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: campfire (SOURCE) → heat traveling through air (intermediate step) → hands (DESTINATION). The SOURCE is the campfire where chemical energy converts to heat energy, it transfers through the air as heat radiation and convection, and the DESTINATION is Emma's hands where the heat energy is absorbed and felt as warmth. Choice C is correct because it shows the complete pathway in the right order: campfire as source, heat through air as the transfer method, and hands as destination. This matches what happens in the scenario and shows the student can trace where energy comes from and where it goes. Choice D is incorrect because it reverses the pathway, suggesting hands are the source and campfire is the destination. This error often happens when students think energy can go backwards or don't understand that heat always flows from hot objects (campfire) to cooler objects (hands). To help students trace pathways: Draw energy pathways with arrows showing direction (campfire → heat through air → hands). Use consistent language: 'Where does it START? Where does it GO? Where does it END?' Practice with familiar examples like warming by a fire, then more complex chains. Act out pathways physically (one student is campfire holding red scarves for 'heat', passes them through 'air' students to 'hands' student). Key skill: Following the path step by step from beginning to end.

Question 8

Maya heats soup: first the stove burner warms the pot, then the pot warms the water, and finally steam rises. Where does the energy start in this scenario?

  1. In the steam
  2. In the water
  3. In the pot
  4. At the stove burner (correct answer)
Explanation: 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: stove burner (SOURCE) → pot (transfers heat) → water (receives heat) → steam (DESTINATION as heated water vapor). The SOURCE is the stove burner producing heat energy, it transfers through the pot, heats the water, and the DESTINATION is the steam carrying thermal energy. Choice D is correct because it identifies the stove burner as the source—the place where heat energy originates in this cooking scenario. This matches what happens in the scenario and shows the student can trace where energy comes from and where it goes. Choice B is incorrect because it identifies the water as the source, but water is receiving energy, not producing it. This error often happens when students see the bubbling water and think that's where heat starts rather than tracing back to the original source. To help students trace pathways: Draw energy pathways with arrows showing direction (burner → pot → water → steam). Use consistent language: 'Where does it START? Where does it GO? Where does it END?' Practice with cooking examples, always starting at the heat source. Act out pathways physically (one student is burner making 'heat', passes to pot student, then to water student, finally to steam student). Key skill: Always trace back to the original energy source, not just what we see changing.

Question 9

In this energy transfer, first Sofia talks, then sound travels through the air, and finally the sound reaches Chen's ear so he can hear. Where does the energy start in this scenario?

  1. In Chen's ear
  2. In the air
  3. In Sofia's voice (correct answer)
  4. In Chen's brain
Explanation: 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: 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? Where does it END?' Practice with familiar examples, then more complex chains. Act out pathways physically (one student is voice, one is air, one is ear—pass 'energy' object along chain). Key skill: Following the path step by step from beginning to end.

Question 10

Emma flips a switch: battery → wire → switch (on) → bulb. Where does energy start?

  1. At the wire
  2. At the battery (correct answer)
  3. At the bulb
  4. At the switch
Explanation: 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 (source) → wire → switch → bulb (destination). The SOURCE is the battery where chemical energy is stored, it transfers through the wire and switch, and the DESTINATION is the bulb where electrical energy becomes light. Choice B is correct because it correctly identifies the battery as the source—the starting point where energy originates in this circuit. This matches what happens in the scenario and shows the student can trace where energy comes from and where it goes. Choice C is incorrect because it identifies the bulb as the source, but the bulb is actually the destination where energy ends up as light. This error often happens when students confuse where they see the effect (light) with where energy actually starts (battery). To help students trace pathways: Draw energy pathways with arrows showing direction (battery → wire → switch → bulb). Use consistent language: 'Where does it START? Where does it GO? Where does it END?' Practice with familiar examples like flashlights, then more complex chains. Act out pathways physically (one student is battery, one is wire, one is switch, one is bulb—pass 'energy' object along chain). Key skill: Following the path step by step from beginning to end.

Question 11

Based on the pathway described, Sofia reads by sunlight: Sun → window → book → eyes. Where does the energy end up?

  1. Sofia's eyes (correct answer)
  2. The Sun
  3. The window glass
  4. The book cover
Explanation: 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: Sun (SOURCE) → window (intermediate step) → book (intermediate step) → eyes (DESTINATION). The SOURCE is the Sun where light energy originates, it transfers through the window, reflects off the book, and the DESTINATION is Sofia's eyes where the light energy is absorbed and allows her to see. Choice A is correct because it identifies Sofia's eyes as the destination—the ending point where energy is finally used. This matches what happens in the scenario and shows the student can trace where energy comes from and where it goes. Choice B is incorrect because it identifies the Sun as the destination, but the Sun is actually the source where energy starts, not where it ends. This error often happens when students reverse the pathway or don't realize that seeing requires light to enter our eyes. To help students trace pathways: Draw energy pathways with arrows showing direction (Sun → window → book → eyes). Use consistent language: 'Where does it START? Where does it GO? Where does it END?' Practice with familiar examples like reading by sunlight, then more complex chains. Act out pathways physically (one student is Sun, one is window, one is book, one is eyes—pass 'light energy' object along chain). Key skill: Following the path step by step from beginning to end.

Question 12

Marcus uses a solar garden light: Sun → solar panel → battery stores energy → LED lights at night. Where does energy start?

  1. The battery
  2. The solar panel
  3. The Sun (correct answer)
  4. The LED light
Explanation: 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: Sun (SOURCE) → solar panel → battery stores energy → LED lights at night (DESTINATION). The SOURCE is the Sun producing light energy, it transfers through the solar panel which converts it to electricity, stores in the battery, and the DESTINATION is the LED light shining at night. Choice C is correct because it correctly identifies the Sun as the ultimate source—the starting point where all the energy in this system originates as sunlight. Choice B is incorrect because it identifies the solar panel as the source, but the panel is actually an intermediate step that captures and converts the Sun's energy, not where energy originates. This error often happens when students confuse energy converters with energy sources. To help students trace pathways: Draw energy pathways with arrows showing direction (Sun → solar panel → battery → LED). Use consistent language: 'Where does it START? Where does it GO? Where does it END?' Practice identifying ultimate sources versus converters and storage. Act out pathways physically (one student is Sun, one is solar panel catching light, one is battery storing, one is LED using stored energy). Key skill: Distinguishing between the ultimate energy source and devices that capture, convert, or store energy.

Question 13

Keisha makes a simple circuit: first energy leaves the battery, then goes through a wire and switch, and finally reaches the bulb. What is the source of energy in this scenario?

  1. The switch
  2. The wire
  3. The battery (correct answer)
  4. The light bulb
Explanation: 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 (SOURCE) → wire (carries electricity) → switch (controls flow) → bulb (DESTINATION). The SOURCE is the battery storing chemical energy that converts to electrical energy, it transfers through the wire and switch, and the DESTINATION is the bulb where electrical energy becomes light. Choice C is correct because it identifies the battery as the source—the component that provides the energy for the entire circuit. This matches what happens in the scenario and shows the student can trace where energy comes from and where it goes. Choice B is incorrect because it identifies the wire as the source, but wire only carries energy, it doesn't create it. This error often happens when students confuse the pathway (wire) with the source (battery). To help students trace pathways: Draw energy pathways with arrows showing direction (battery → wire → switch → bulb). Use consistent language: 'Where does it START? Where does it GO? Where does it END?' Practice with circuit examples, always identifying the battery or power source first. Act out pathways physically (one student is battery with 'energy' balls, passes through 'wire' students and 'switch' to 'bulb' who lights up). Key skill: Recognizing that batteries store and provide energy, while wires and switches just help it travel.

Question 14

Jamal speaks: his voice makes sound → sound travels through air → reaches Sofia's ear. Where does the energy end up?

  1. In Jamal's mouth
  2. In the air
  3. In Sofia's ear (correct answer)
  4. In Jamal's lungs
Explanation: 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: Jamal's voice/lungs (SOURCE) → sound travels through air → reaches Sofia's ear (DESTINATION). The SOURCE is Jamal creating the sound, it transfers through the air as sound waves, and the DESTINATION is Sofia's ear where the sound energy is received. Choice C is correct because it correctly identifies Sofia's ear as the destination—the ending point where sound energy arrives and is detected. Choice B is incorrect because it identifies the air as the destination, but air is actually the medium through which sound travels, not where it ends up. This error often happens when students confuse the pathway (what energy travels through) with the destination (where energy finally arrives). To help students trace pathways: Draw energy pathways with arrows showing direction (voice → air → ear). Use consistent language: 'Where does it START? Where does it GO? Where does it END?' Practice with sound examples like talking, music, and echoes. Act out pathways physically (one student makes sound, others represent air molecules passing vibrations, last student is the ear receiving sound). Key skill: Distinguishing between the medium (what carries energy) and the destination (where energy ends up).

Question 15

Diego uses solar lights: first sunlight hits a solar panel, then the panel makes electric energy, next it charges a battery, and finally an LED light turns on. Trace the energy: what is the correct order of steps?

  1. Sun → solar panel → battery → LED light (correct answer)
  2. Solar panel → Sun → battery → LED light
  3. Sun → battery → solar panel → LED light
  4. Sun → solar panel → LED light → battery
Explanation: 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: Sun (SOURCE) → solar panel → battery → LED light (DESTINATION). The SOURCE is the Sun where light energy originates, it transfers to the solar panel which converts it to electricity, stores in the battery, and the DESTINATION is the LED light that uses the energy. Choice A is correct because it shows the complete pathway in the right order from start to finish. This matches what happens in the scenario and shows the student can trace where energy comes from and where it goes. Choice D is incorrect because it shows the LED light before the battery, suggesting the light turns on before getting energy from the battery, which scrambles the order of energy storage and use. This error often happens when students don't understand that batteries store energy before devices can use it. To help students trace pathways: Draw energy pathways with arrows showing direction (Sun → panel → battery → light). Use consistent language: 'Where does it START? Where does it GO? Where does it END?' Practice with familiar examples like solar-powered devices, then more complex chains. Act out pathways physically (one student is Sun, one is solar panel, one is battery, one is light—pass 'energy' object along chain, showing how it changes from light to electricity). Key skill: Following the path step by step from beginning to end.

Question 16

In this energy transfer, first Emma flips a switch, then energy goes from the battery through wires to the bulb, and finally the bulb gives off light. What is the pathway of energy transfer from start to finish?

  1. Battery → wires → switch → bulb → light (correct answer)
  2. Switch → wires → battery → bulb → light
  3. Battery → bulb → light → wires → switch
  4. Battery → bulb → light → light switch → wires
Explanation: 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.

Question 17

Chen warms up near a campfire: first heat comes from the fire, then it travels through the air, and finally it reaches Chen's hands. In this energy transfer, which correctly describes how energy moves?

  1. Chen's hands → air → campfire
  2. Campfire → air → Chen's hands (correct answer)
  3. Air → campfire → Chen's hands
  4. Campfire → Chen's hands → air
Explanation: 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: campfire (SOURCE) → air → Chen's hands (DESTINATION). The SOURCE is the campfire where heat energy is produced, it transfers through the air as heat radiation and convection, and the DESTINATION is Chen's hands where he feels warmth. Choice B is correct because it shows the complete pathway in the right order: campfire → air → Chen's hands. This matches what happens in the scenario and shows the student can trace where energy comes from and where it goes. Choice A is incorrect because it reverses the pathway, suggesting heat starts at Chen's hands and goes to the campfire, which violates how heat naturally flows from hot to cold. This error often happens when students think energy can go backwards or don't understand that heat always flows from warmer objects to cooler ones. To help students trace pathways: Draw energy pathways with arrows showing direction (fire → air → hands). Use consistent language: 'Where does it START? Where does it GO? Where does it END?' Practice with familiar examples like warming by a fire, then more complex chains. Act out pathways physically (one student is fire, one represents air/heat waves, one is person—pass 'heat energy' object along chain). Key skill: Following the path step by step from beginning to end.

Question 18

Yuki plays a guitar near a drum: first the guitar string vibrates, then sound travels through air, next it hits the drum, and finally the drum vibrates. Based on the pathway described, where does the energy start?

  1. The drum
  2. The air in the room
  3. The guitar string (correct answer)
  4. Yuki's ears
Explanation: 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: guitar string (SOURCE) → air → drum → drum vibrates (DESTINATION). The SOURCE is the guitar string where sound energy begins when it vibrates, it transfers through air as sound waves, hits the drum, and the DESTINATION is the vibrating drum. Choice C is correct because it correctly identifies the guitar string as the source where energy starts. This matches what happens in the scenario and shows the student can trace where energy comes from and where it goes. Choice A is incorrect because it identifies the drum as the starting point, but the drum is actually the destination that receives the sound energy from the guitar. This error often happens when students confuse cause and effect or don't realize that one instrument can make another vibrate through sound waves. To help students trace pathways: Draw energy pathways with arrows showing direction (guitar string → air → drum). Use consistent language: 'Where does it START? Where does it GO? Where does it END?' Practice with familiar examples like musical instruments affecting each other, then more complex chains. Act out pathways physically (one student plucks imaginary guitar, others represent sound waves moving through air, last student is drum that starts vibrating—pass 'sound energy' object along chain). Key skill: Following the path step by step from beginning to end.

Question 19

In this energy transfer, first Diego puts a metal spoon in a cup of hot water, then heat moves from the water to the cup, next it moves into the spoon, and finally the spoon handle gets warm. Where does the energy end up?

  1. In the hot water
  2. In the spoon handle (correct answer)
  3. In the cup only
  4. In the air above the cup
Explanation: 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: hot water → cup → spoon → spoon handle; the SOURCE is the hot water, it transfers through the cup and spoon, and the DESTINATION is the spoon handle getting warm. For example: the hot water is the source, heat conducts to the cup, then to the spoon, and warms the handle—the destination. Choice B is correct because it correctly identifies the destination as the spoon handle, where the heat energy ends up. Choice A is incorrect because it identifies the wrong ending point as the hot water, which is the source. This error often happens when students reverse the pathway 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. Act out pathways physically (one student is hot water, one is cup, one is spoon—pass 'energy' object along chain). Key skill: Following the path step by step from beginning to end.

Question 20

This scenario shows an energy chain: first wind turns a turbine, then a generator makes electric current, next the current travels through wires, and finally lights in a house turn on. What is the source of energy in this scenario?

  1. The house lights
  2. The wires
  3. The wind (correct answer)
  4. The generator
Explanation: 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: 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. Choice A is incorrect because it identifies the wrong starting point as the house lights, which is the destination. This error often happens when students reverse the pathway or confuse the medium like wires 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? Where does it END?' Practice with familiar examples, then more complex chains. Act out pathways physically (one student is wind, one is turbine, one is generator, one is lights—pass 'energy' object along chain). Key skill: Following the path step by step from beginning to end.
