Question 1

The spoon handle warms up, showing heat moved from soup to spoon. (correct answer)
The spoon looks shiny, showing light moved from spoon to soup.
The soup makes a noise, showing sound moved from spoon to air.
The spoon is metal, showing electric current moved without a circuit.

Explanation: This question tests 4th grade ability to identify and observe different types of energy transfer: sound, light, heat, and electric current (NGSS 4-PS3-2). Students must recognize evidence that energy is moving from one place to another. Energy transfer means energy moves from one place to another. Sound transfers energy through vibrations in air (or other materials). Light transfers energy through space in all directions from a source. Heat transfers energy from hotter objects to cooler objects. Electric current transfers energy through wires and conductive materials. In this scenario, Chen places a metal spoon in hot soup, observing the spoon handle warming up and staying warm briefly after removal. The energy starts at the hot soup (source) and transfers to the spoon (destination). We can observe this transfer because we feel the handle getting warmer, indicating heat conduction through the metal. This shows heat energy transfer occurring. Choice A is correct because it identifies heat energy transfer, which matches the observations in the scenario. The evidence that supports this is the spoon handle warming up, showing heat moving from soup to spoon. This shows the student can recognize this type of energy transfer from observable effects. Choice B is incorrect because it claims light energy moved from spoon to soup, making it shiny. This is wrong because no brightness or visual travel is observed; instead, temperature changes occur. Students sometimes confuse different energy types, such as mistaking thermal effects for optical ones. To help students: Create a chart of the four transfer types with examples and evidence for each. Conduct demonstrations: ring bell (sound—hear it across room), shine flashlight (light—see it on wall), heat metal spoon (heat—handle gets warm), complete circuit (electric—bulb lights). Practice identifying: What type? Where does it start? Where does it go? What's the evidence? Key vocabulary: transfer = move from place to place. All four types transfer energy but in different ways.

Question 2

Maya claps her hands (source) near her friend Marcus (destination). Marcus hears a loud clap when he is close. When Marcus steps back several meters, the clap sounds quieter. In this observation, how is energy moving from one place to another?

Sound energy travels through air from Maya's hands to Marcus's ears. (correct answer)
Light energy travels through air from Maya's hands to Marcus's eyes.
Heat energy transfers from Marcus's ears to Maya's hands as he listens.
Electric current flows from Maya's hands to Marcus without any wires.

Explanation: This question tests 4th grade ability to identify and observe different types of energy transfer: sound, light, heat, and electric current (NGSS 4-PS3-2). Students must recognize evidence that energy is moving from one place to another. Energy transfer means energy moves from one place to another. Sound transfers energy through vibrations in air (or other materials). Light transfers energy through space in all directions from a source. Heat transfers energy from hotter objects to cooler objects. Electric current transfers energy through wires and conductive materials. In this scenario, Maya claps her hands, and Marcus hears it louder when closer and quieter when farther away. The energy starts at Maya's hands (source) and transfers to Marcus's ears (destination). We can observe this transfer because the clap is heard with volume changing by distance, indicating vibrations in air. This shows sound energy transfer occurring. Choice A is correct because it identifies sound energy transfer, which matches the observations in the scenario. The evidence that supports this is the clap sounding quieter farther away, showing sound moving through air. This shows the student can recognize this type of energy transfer from observable effects. Choice B is incorrect because it claims light energy transfer to Marcus's eyes. This is wrong because no visual effects like brightness are observed; instead, auditory changes occur. Students sometimes confuse different energy types, such as hearing with seeing. To help students: Create a chart of the four transfer types with examples and evidence for each. Conduct demonstrations: ring bell (sound—hear it across room), shine flashlight (light—see it on wall), heat metal spoon (heat—handle gets warm), complete circuit (electric—bulb lights). Practice identifying: What type? Where does it start? Where does it go? What's the evidence? Key vocabulary: transfer = move from place to place. All four types transfer energy but in different ways.

Question 3

Chen turns on a flashlight and points it at a wall. The bright spot appears on the wall, and when he covers the flashlight, the spot disappears. In this observation, which type of energy is being transferred?

Sound energy transfers from the flashlight to the wall.
Light energy transfers from the flashlight to the wall. (correct answer)
Heat energy transfers from the wall to the flashlight.
Electric current transfers through the air from the wall to Chen.

Explanation: This question tests 4th grade ability to identify and observe different types of energy transfer: sound, light, heat, and electric current (NGSS 4-PS3-2). Students must recognize evidence that energy is moving from one place to another. Energy transfer means energy moves from one place to another. Sound transfers energy through vibrations in air (or other materials). Light transfers energy through space in all directions from a source. Heat transfers energy from hotter objects to cooler objects. Electric current transfers energy through wires and conductive materials. In this scenario, Chen's flashlight creates a bright spot on the wall that appears and disappears with the light beam. The energy starts at the flashlight and transfers to the wall. We can observe this transfer because we see the bright spot appear on the wall when the flashlight is on. This shows light energy transfer occurring. Choice B is correct because it identifies light energy transfer, which matches the observations in the scenario. The evidence that supports this is the visible bright spot that appears on the wall and disappears when the flashlight is covered. This shows the student can recognize light energy transfer from observable effects. Choice A is incorrect because it claims sound energy transfer. This is wrong because no vibrations or sounds are mentioned - only a visible bright spot. Students sometimes confuse different energy types when multiple forms might be present. To help students: Create a chart of the four transfer types with examples and evidence for each. Conduct demonstrations: ring bell (sound—hear it across room), shine flashlight (light—see it on wall), heat metal spoon (heat—handle gets warm), complete circuit (electric—bulb lights). Practice identifying: What type? Where does it start? Where does it go? What's the evidence? Key vocabulary: transfer = move from place to place. All four types transfer energy but in different ways.

Question 4

Yuki turns on a desk lamp (source) and aims it at her book (destination). The page becomes bright, and she can read the words clearly. When she blocks the lamp with a folder, the page becomes dark again. What type of energy is being transferred in this observation?

Heat energy transfers from the book to the lamp, making the page brighter.
Light energy travels from the lamp to the book, lighting the page. (correct answer)
Sound energy travels from the book to Yuki's ears, helping her read.
Electric current flows through the air from the lamp to the book.

Explanation: This question tests 4th grade ability to identify and observe different types of energy transfer: sound, light, heat, and electric current (NGSS 4-PS3-2). Students must recognize evidence that energy is moving from one place to another. Energy transfer means energy moves from one place to another. Sound transfers energy through vibrations in air (or other materials). Light transfers energy through space in all directions from a source. Heat transfers energy from hotter objects to cooler objects. Electric current transfers energy through wires and conductive materials. In this scenario, Yuki turns on a lamp aimed at her book, observing the page brightening and darkening when blocked. The energy starts at the lamp (source) and transfers to the book (destination). We can observe this transfer because the page becomes visible and bright, disappearing when obstructed. This shows light energy transfer occurring. Choice B is correct because it identifies light energy transfer, which matches the observations in the scenario. The evidence that supports this is the page lighting up and becoming dark when blocked, showing light traveling through space. This shows the student can recognize this type of energy transfer from observable effects. Choice D is incorrect because it claims electric current flows through the air from lamp to book. This is wrong because no wires or circuit are involved, and the effect is visual not electrical flow. Students sometimes confuse energy transfer types like light with electric current. To help students: Create a chart of the four transfer types with examples and evidence for each. Conduct demonstrations: ring bell (sound—hear it across room), shine flashlight (light—see it on wall), heat metal spoon (heat—handle gets warm), complete circuit (electric—bulb lights). Practice identifying: What type? Where does it start? Where does it go? What's the evidence? Key vocabulary: transfer = move from place to place. All four types transfer energy but in different ways.

Question 5

Jamal rings a small bell (source) at the front of the classroom. Students across the room (destination) can hear the ringing, but it sounds quieter farther away. When Jamal closes the classroom door, students in the hallway hear it much softer. Based on what happened, what type of energy transfer do these observations show?

Sound energy travels through air from the bell to the students' ears. (correct answer)
Light energy travels from the bell to the students' eyes.
Heat energy transfers from the students to the bell, making it ring.
Electric current flows from the bell through the air to the hallway.

Explanation: This question tests 4th grade ability to identify and observe different types of energy transfer: sound, light, heat, and electric current (NGSS 4-PS3-2). Students must recognize evidence that energy is moving from one place to another. Energy transfer means energy moves from one place to another. Sound transfers energy through vibrations in air (or other materials). Light transfers energy through space in all directions from a source. Heat transfers energy from hotter objects to cooler objects. Electric current transfers energy through wires and conductive materials. In this scenario, Jamal rings a bell, and students hear it quieter from farther away or through a closed door. The energy starts at the bell (source) and transfers to the students' ears (destination). We can observe this transfer because we hear the ringing sound across the room, which diminishes with distance or barriers. This shows sound energy transfer occurring. Choice A is correct because it identifies sound energy transfer, which matches the observations in the scenario. The evidence that supports this is the sound being heard quieter farther away and muffled through the door, showing vibrations moving through air. This shows the student can recognize this type of energy transfer from observable effects. Choice B is incorrect because it claims light energy transfer to the students' eyes. This is wrong because no visual changes like brightness are observed; instead, auditory effects occur. Students sometimes confuse different energy types, such as mistaking hearing for seeing. To help students: Create a chart of the four transfer types with examples and evidence for each.

Students must recognize evidence that energy is moving from one place to another. Energy transfer means energy moves from one place to another. Sound transfers energy through vibrations in air (or other materials). Light transfers energy through space in all directions from a source. Heat transfers energy from hotter objects to cooler objects. Electric current transfers energy through wires and conductive materials. In this scenario, Yuki plugs in a charger, connects to the phone, and the battery starts charging. The energy starts at the outlet and transfers to the phone. We can observe this transfer because the phone shows a charging symbol and battery percent rises. This shows electric current energy transfer occurring. Choice D is correct because it identifies electric current energy transfer, which matches the observations in the scenario. The evidence that supports this is the phone charging through the cord. This shows the student can recognize this type of energy transfer from observable effects. Choice B is incorrect because it claims light energy through the cord. This is wrong because no light is observed, and the transfer is through conductive materials, not light. Students sometimes confuse different energy types like electric and light when devices have screens or indicators. To help students: Create a chart of the four transfer types with examples and evidence for each. Conduct demonstrations: ring bell (sound—hear it across room), shine flashlight (light—see it on wall), heat metal spoon (heat—handle gets warm), complete circuit (electric—bulb lights).

Students must recognize evidence that energy is moving from one place to another. Energy transfer means energy moves from one place to another. Sound transfers energy through vibrations in air (or other materials). Light transfers energy through space in all directions from a source. Heat transfers energy from hotter objects to cooler objects. Electric current transfers energy through wires and conductive materials. In this scenario, Maya rings a bell, and students hear it a moment later without seeing it. The energy starts at the bell and transfers to the students' ears. We can observe this transfer because we hear the ringing across the room. This shows sound energy transfer occurring. Choice B is correct because it identifies sound energy transfer, which matches the observations in the scenario. The evidence that supports this is hearing the bell even when it's not visible. This shows the student can recognize this type of energy transfer from observable effects. Choice A is incorrect because it claims light energy to the eyes. This is wrong because the students cannot see the bell, so no light transfer is observed. Students sometimes confuse different energy types like sound and light when something is heard but not seen. To help students: Create a chart of the four transfer types with examples and evidence for each. Conduct demonstrations: ring bell (sound—hear it across room), shine flashlight (light—see it on wall), heat metal spoon (heat—handle gets warm), complete circuit (electric—bulb lights). Practice identifying: What type? Where does it start? Where does it go? What's the evidence? Key vocabulary: transfer = move from place to place. All four types transfer energy but in different ways.

Sound energy transfers from the sun to the floor through the window.
Light energy transfers from the sun to the floor through the window. (correct answer)
Electric current transfers from the floor to the sun through the air.
Heat energy transfers from the floor to the sunlight patch in the air.

Explanation: This question tests 4th grade ability to identify and observe different types of energy transfer: sound, light, heat, and electric current (NGSS 4-PS3-2). Students must recognize evidence that energy is moving from one place to another. Energy transfer means energy moves from one place to another. Sound transfers energy through vibrations in air (or other materials). Light transfers energy through space in all directions from a source. Heat transfers energy from hotter objects to cooler objects. Electric current transfers energy through wires and conductive materials. In this scenario, sunlight creates a bright patch on the floor through the window, and the floor feels warmer. The energy starts at the sun and transfers to the floor. We can observe this transfer because we see the bright patch and feel the warmth. This shows light energy transfer occurring. Choice B is correct because it identifies light energy transfer, which matches the observations in the scenario. The evidence that supports this is the bright patch appearing on the floor from the sunlight. This shows the student can recognize this type of energy transfer from observable effects. Choice D is incorrect because it claims heat energy from the floor to the sunlight patch. This is wrong because the direction is reversed, and the primary transfer is via light, with warmth as a result. Students sometimes confuse different energy types like light and heat when light causes heating. To help students: Create a chart of the four transfer types with examples and evidence for each. Conduct demonstrations: ring bell (sound—hear it across room), shine flashlight (light—see it on wall), heat metal spoon (heat—handle gets warm), complete circuit (electric—bulb lights).

Explanation: This question tests 4th grade ability to identify and observe different types of energy transfer: sound, light, heat, and electric current (NGSS 4-PS3-2). Students must recognize evidence that energy is moving from one place to another. Energy transfer means energy moves from one place to another. Sound transfers energy through vibrations in air (or other materials). Light transfers energy through space in all directions from a source. Heat transfers energy from hotter objects to cooler objects. Electric current transfers energy through wires and conductive materials. In this scenario, Keisha plucks a guitar string softly then harder, hearing soft and loud sounds, feeling vibrations. The energy starts at the vibrating string and transfers to Keisha's ears. We can observe this transfer because we hear the sounds and feel the vibrations. This shows sound energy transfer occurring. Choice A is correct because it identifies sound energy transfer, which matches the observations in the scenario. The evidence that supports this is hearing softer and louder sounds from the plucks. This shows the student can recognize this type of energy transfer from observable effects. Choice B is incorrect because it claims light energy to the ears. This is wrong because no light is observed from the string, only sound and vibrations. Students sometimes confuse different energy types like sound and light when vibrations are visible but the effect is audible. To help students: Create a chart of the four transfer types with examples and evidence for each. Conduct demonstrations: ring bell (sound—hear it across room), shine flashlight (light—see it on wall), heat metal spoon (heat—handle gets warm), complete circuit (electric—bulb lights).

Explanation: This question tests 4th grade ability to identify and observe different types of energy transfer: sound, light, heat, and electric current (NGSS 4-PS3-2). Students must recognize evidence that energy is moving from one place to another. Energy transfer means energy moves from one place to another. Sound transfers energy through vibrations in air (or other materials). Light transfers energy through space in all directions from a source. Heat transfers energy from hotter objects to cooler objects. Electric current transfers energy through wires and conductive materials. In this scenario, Keisha sits near a space heater, observing her hands warming up more when closer and less when farther away. The energy starts at the heater (source) and transfers to her hands (destination). We can observe this transfer because we feel the warmth increasing with proximity, indicating heat radiation. This shows heat energy transfer occurring. Choice B is correct because it identifies heat energy transfer, which matches the observations in the scenario. The evidence that supports this is the hands feeling warmer near the heater and less so farther away. This shows the student can recognize this type of energy transfer from observable effects. Choice A is incorrect because it claims sound energy transfers from heater to hands, warming them. This is wrong because no vibrations or sounds are observed; instead, temperature changes occur. Students sometimes confuse heat with sound due to similar distance effects. To help students: Create a chart of the four transfer types with examples and evidence for each. Conduct demonstrations: ring bell (sound—hear it across room), shine flashlight (light—see it on wall), heat metal spoon (heat—handle gets warm), complete circuit (electric—bulb lights).

Sound transfers energy through vibrations in air (or other materials). Light transfers energy through space in all directions from a source. Heat transfers energy from hotter objects to cooler objects. Electric current transfers energy through wires and conductive materials. In this scenario, Carlos plugs a charger into an outlet and connects to the phone, observing the charging symbol and battery increase, stopping when unplugged. The energy starts at the outlet (source) and transfers to the phone (destination). We can observe this transfer because the battery percent rises and the symbol appears only when connected. This shows electric current energy transfer occurring. Choice C is correct because it identifies electric current energy transfer, which matches the observations in the scenario. The evidence that supports this is the charging symbol and battery increase when plugged in, showing flow through the cord. This shows the student can recognize this type of energy transfer from observable effects. Choice A is incorrect because it claims light energy transfers from outlet to phone, making the screen brighter. This is wrong because no brightness change is directly from transfer, and it's not through air but wires. Students sometimes confuse electric current with light effects from devices. To help students: Create a chart of the four transfer types with examples and evidence for each. Conduct demonstrations: ring bell (sound—hear it across room), shine flashlight (light—see it on wall), heat metal spoon (heat—handle gets warm), complete circuit (electric—bulb lights).

Heat transfers energy from hotter objects to cooler objects. Electric current transfers energy through wires and conductive materials. In this scenario, Amir connects a battery to a bulb with wires, observing the bulb lighting up when the circuit is complete and turning off when disconnected. The energy starts at the battery (source) and transfers to the bulb (destination). We can observe this transfer because the bulb lights up immediately upon connection, indicating flow through wires. This shows electric current energy transfer occurring. Choice C is correct because it identifies electric current energy transfer, which matches the observations in the scenario. The evidence that supports this is the bulb lighting when connected and turning off when disconnected, showing energy moving through the circuit. This shows the student can recognize this type of energy transfer from observable effects. Choice D is incorrect because it claims heat energy moving from the bulb back to the battery. This is wrong because no temperature changes are mentioned, and the direction is reversed; not in a circuit so not electric current in that way. Students sometimes confuse energy transfer with transformation or direction. To help students: Create a chart of the four transfer types with examples and evidence for each. Conduct demonstrations: ring bell (sound—hear it across room), shine flashlight (light—see it on wall), heat metal spoon (heat—handle gets warm), complete circuit (electric—bulb lights).

This shows the student can recognize this type of energy transfer from observable effects. Choice D is incorrect because it claims light energy moved from the speaker, making the room bright. This is wrong because no brightness is observed from the speaker; instead, auditory effects occur. Students sometimes confuse sound with light when devices produce both. To help students: Create a chart of the four transfer types with examples and evidence for each. Conduct demonstrations: ring bell (sound—hear it across room), shine flashlight (light—see it on wall), heat metal spoon (heat—handle gets warm), complete circuit (electric—bulb lights). Practice identifying: What type? Where does it start? Where does it go? What's the evidence? Key vocabulary: transfer = move from place to place. All four types transfer energy but in different ways.

Question 16

Sofia holds an ice cube (destination) in her warm hand (source). After a minute, her hand feels colder, and the ice cube starts to melt. Water drips from the ice cube into the sink. In this observation, which statement correctly describes the energy transfer happening?

Light energy travels from the ice cube to Sofia's hand, making it feel cold.
Heat energy transfers from Sofia's hand to the ice cube, causing melting. (correct answer)
Sound energy transfers from the ice cube to Sofia's ears, causing dripping.
Heat energy transfers from the ice cube to Sofia's hand, causing melting.

Explanation: This question tests 4th grade ability to identify and observe different types of energy transfer: sound, light, heat, and electric current (NGSS 4-PS3-2). Students must recognize evidence that energy is moving from one place to another. Energy transfer means energy moves from one place to another. Sound transfers energy through vibrations in air (or other materials). Light transfers energy through space in all directions from a source. Heat transfers energy from hotter objects to cooler objects. Electric current transfers energy through wires and conductive materials. In this scenario, Sofia holds an ice cube in her warm hand, observing her hand getting colder and the ice melting with water dripping. The energy starts at her warm hand (source) and transfers to the ice cube (destination). We can observe this transfer because we feel the hand cooling and see the ice melting, indicating heat moving from hotter to cooler. This shows heat energy transfer occurring. Choice B is correct because it identifies heat energy transfer, which matches the observations in the scenario. The evidence that supports this is the hand feeling colder and the ice melting, showing heat moving from hand to ice. This shows the student can recognize this type of energy transfer from observable effects. Choice D is incorrect because it claims heat energy transfers from the ice cube to the hand, causing melting. This is wrong because heat flows from hotter (hand) to cooler (ice), not the reverse; no temperature change so not heat in that direction. Students sometimes confuse the direction of heat transfer with the observed effects like melting. To help students: Create a chart of the four transfer types with examples and evidence for each. Conduct demonstrations: ring bell (sound—hear it across room), shine flashlight (light—see it on wall), heat metal spoon (heat—handle gets warm), complete circuit (electric—bulb lights). Practice identifying: What type? Where does it start? Where does it go? What's the evidence? Key vocabulary: transfer = move from place to place. All four types transfer energy but in different ways.

Question 17

Keisha plugs a phone charger into a wall outlet and connects it to a tablet. The tablet shows a charging symbol, but it stops when she unplugs the charger. What evidence shows that energy is being transferred?

The charging symbol appears, showing electric current flows from outlet to tablet. (correct answer)
The charger looks white, showing light energy moves from tablet to outlet.
The tablet makes no sound, showing sound energy is blocked by the cord.
The outlet is on the wall, showing heat energy moves from tablet to outlet.

Explanation: This question tests 4th grade ability to identify and observe different types of energy transfer: sound, light, heat, and electric current (NGSS 4-PS3-2). Students must recognize evidence that energy is moving from one place to another. Energy transfer means energy moves from one place to another. Sound transfers energy through vibrations in air (or other materials). Light transfers energy through space in all directions from a source. Heat transfers energy from hotter objects to cooler objects. Electric current transfers energy through wires and conductive materials. In this scenario, Keisha connects a charger between a wall outlet and tablet, seeing a charging symbol that stops when unplugged. The energy starts at the wall outlet and transfers through the charger cord to the tablet. We can observe this transfer because the charging symbol appears when connected and disappears when disconnected. This shows electric current energy transfer occurring. Choice A is correct because it identifies that the charging symbol shows electric current flows from outlet to tablet. The evidence that supports this is the charging symbol appearing only when the charger connects the outlet to the tablet. This shows the student can recognize electric current transfer from observable device responses. Choice C is incorrect because it claims the tablet makes no sound, showing sound energy is blocked. This is wrong because the question asks what energy IS being transferred, not what isn't present. Students sometimes confuse the absence of one energy type with evidence for another. To help students: Create a chart of the four transfer types with examples and evidence for each. Conduct demonstrations: ring bell (sound—hear it across room), shine flashlight (light—see it on wall), heat metal spoon (heat—handle gets warm), complete circuit (electric—bulb lights). Practice identifying: What type? Where does it start? Where does it go? What's the evidence? Key vocabulary: transfer = move from place to place. All four types transfer energy but in different ways.

Question 18

Sofia connects a battery to a small bulb with two wires. When the circuit is complete, the bulb lights up, but it turns off when a wire is removed. Based on what happened, what type of energy transfer is shown?

Electric current transfers from the battery through the wires to the bulb. (correct answer)
Heat transfers from the bulb through the wires to the battery.
Sound transfers from the battery through the air to the bulb.
Light transfers from the wires through the battery to the room.

Explanation: This question tests 4th grade ability to identify and observe different types of energy transfer: sound, light, heat, and electric current (NGSS 4-PS3-2). Students must recognize evidence that energy is moving from one place to another. Energy transfer means energy moves from one place to another. Sound transfers energy through vibrations in air (or other materials). Light transfers energy through space in all directions from a source. Heat transfers energy from hotter objects to cooler objects. Electric current transfers energy through wires and conductive materials. In this scenario, Sofia connects a battery to a bulb with wires, and the bulb lights when the circuit is complete but turns off when a wire is removed. The energy starts at the battery and transfers through the wires to the bulb. We can observe this transfer because the bulb lights up when connected and turns off when disconnected. This shows electric current energy transfer occurring. Choice A is correct because it identifies electric current transfer from the battery through the wires to the bulb. The evidence that supports this is the bulb lighting only when the circuit is complete with wires connecting battery to bulb. This shows the student can recognize electric current transfer from observable circuit effects. Choice B is incorrect because it claims heat transfers from the bulb to the battery. This is wrong because the primary energy flow is electric current from battery to bulb, not heat in the reverse direction. Students sometimes confuse the heat produced by the bulb with the main energy transfer type. To help students: Create a chart of the four transfer types with examples and evidence for each. Conduct demonstrations: ring bell (sound—hear it across room), shine flashlight (light—see it on wall), heat metal spoon (heat—handle gets warm), complete circuit (electric—bulb lights). Practice identifying: What type? Where does it start? Where does it go? What's the evidence? Key vocabulary: transfer = move from place to place. All four types transfer energy but in different ways.

Question 19

Carlos plays music from a small speaker on a table. He can hear the music across the room, but it is quieter when he steps into the hallway. In this observation, which type of energy is being transferred?

Light energy transfers from the speaker to Carlos's eyes.
Electric current transfers through the air from the hallway to the speaker.
Sound energy transfers from the speaker through air to Carlos's ears. (correct answer)
Heat energy transfers from Carlos's ears to the speaker.

Explanation: This question tests 4th grade ability to identify and observe different types of energy transfer: sound, light, heat, and electric current (NGSS 4-PS3-2). Students must recognize evidence that energy is moving from one place to another. Energy transfer means energy moves from one place to another. Sound transfers energy through vibrations in air (or other materials). Light transfers energy through space in all directions from a source. Heat transfers energy from hotter objects to cooler objects. Electric current transfers energy through wires and conductive materials. In this scenario, Carlos plays music from a speaker that he can hear across the room but is quieter in the hallway. The energy starts at the speaker and transfers through the air to Carlos's ears. We can observe this transfer because Carlos hears the music at different volumes in different locations. This shows sound energy transfer occurring. Choice C is correct because it identifies sound energy transfer from the speaker through air to Carlos's ears. The evidence that supports this is hearing the music across the room and it being quieter in the hallway, showing sound energy spreading from the source. This shows the student can recognize sound energy transfer from observable audio effects. Choice A is incorrect because it claims light energy transfer from the speaker to Carlos's eyes. This is wrong because the scenario describes hearing music at different volumes, not seeing anything. Students sometimes confuse the different senses and energy types involved. To help students: Create a chart of the four transfer types with examples and evidence for each. Conduct demonstrations: ring bell (sound—hear it across room), shine flashlight (light—see it on wall), heat metal spoon (heat—handle gets warm), complete circuit (electric—bulb lights). Practice identifying: What type? Where does it start? Where does it go? What's the evidence? Key vocabulary: transfer = move from place to place. All four types transfer energy but in different ways.

Question 20

Keisha claps her hands once near her friend, then claps again from farther away. Her friend still hears the clap, but it is quieter farther away. Which statement correctly describes the energy transfer happening?

Sound energy travels through air from Keisha's hands to her friend. (correct answer)
Light energy travels through air from Keisha's hands to her friend.
Heat energy travels from her friend's ears to Keisha's hands.
Electric current travels through air from Keisha's hands to her friend.

Explanation: This question tests 4th grade ability to identify and observe different types of energy transfer: sound, light, heat, and electric current (NGSS 4-PS3-2). Students must recognize evidence that energy is moving from one place to another. Energy transfer means energy moves from one place to another. Sound transfers energy through vibrations in air (or other materials). Light transfers energy through space in all directions from a source. Heat transfers energy from hotter objects to cooler objects. Electric current transfers energy through wires and conductive materials. In this scenario, Keisha claps her hands and her friend hears it, with the sound being quieter when Keisha is farther away. The energy starts at Keisha's clapping hands and transfers through the air to her friend's ears. We can observe this transfer because the friend hears the clap and the volume decreases with distance. This shows sound energy transfer occurring. Choice A is correct because it identifies sound energy traveling through air from Keisha's hands to her friend, which matches the observations in the scenario. The evidence that supports this is the friend hearing the claps and the sound being quieter at greater distance. This shows the student can recognize sound energy transfer from observable auditory effects. Choice D is incorrect because it claims electric current travels through air. This is wrong because electric current requires wires or conductive materials - it cannot travel through air between people. Students sometimes think any energy transfer through air must be electricity. To help students: Create a chart of the four transfer types with examples and evidence for each. Conduct demonstrations: ring bell (sound—hear it across room), shine flashlight (light—see it on wall), heat metal spoon (heat—handle gets warm), complete circuit (electric—bulb lights). Practice identifying: What type? Where does it start? Where does it go? What's the evidence? Key vocabulary: transfer = move from place to place. Sound travels through air as vibrations, while electric current needs wires.
