Energy Transformations worksheet showing various images and arrows for students to identify and write the correct energy types.

Explanation:
We are given a worksheet titled “Energy Transformations” with four rows. Each row shows an energy transformation: something on the left (input) changes into something on the right (output), and we must fill in the correct energy types using the word bank.

Word bank includes:
- Kinetic
- Potential
- Mechanical
- Light
- Radiant
- Chemical
- Stored
- Nuclear
- Sound
- Elastic
- Electrical
- Heat

Let’s go row by row.

Row 1:
Left image: A hand plugging in a lamp (electricity being supplied).
Right image: A lit lamp (producing light and some heat).
→ Input: Electrical energy (from the outlet).
→ Output: Light (and possibly Heat, but the lamp primarily gives light; “Light” is in the word bank, and it's the main visible output).
So:
Left box: Electrical
Right box: Light

Row 2:
Left image: Food (e.g., apple, bread, maybe a banana — clearly food).
Right image: A child running (movement).
→ Food stores Chemical energy (from nutrients).
→ When the body uses it, that becomes Kinetic energy (motion).
So:
Left box: Chemical
Right box: Kinetic

Row 3:
Left image: The Sun (a bright yellow sun with rays).
Right image: A person sweating and looking hot (feeling heat).
→ The Sun emits Radiant energy (also called solar or electromagnetic radiation — “Radiant” is in the word bank).
→ That radiant energy reaches Earth and is absorbed, warming things → becomes Heat.
Note: “Light” is separate, but sunlight includes both light and infrared (heat). Since the person is feeling hot, the main transformation shown is radiant → heat.
So:
Left box: Radiant
Right box: Heat

Row 4:
Left image: Two batteries (chemical energy storage).
Right image: A boombox playing music (sound coming out, also likely light from display, but sound is most obvious).
→ Batteries store Chemical energy, which is converted to Electrical energy inside the device, then to Sound (and maybe some heat/light). But the question asks for the *main* input and output energy types shown.
Input: Chemical (batteries store chemical energy).
Output: The boombox produces Sound (music). “Sound” is in the word bank.
However — wait! In Row 2 we already used “Chemical” for food. Can we reuse words? Yes — the worksheet doesn’t say each word is used once. It says “write the words in the correct place”, and multiple items can involve chemical energy.

But let’s double-check: Is there a better match?
Alternative: Some might say batteries provide Electrical, but the image shows *batteries themselves*, not a circuit — so the stored form is Chemical. The boombox output is clearly Sound (speakers making noise). Also, “Electrical” is used in Row 1, but again, reuse is fine.

So:
Left box: Chemical
Right box: Sound

Wait — hold on! Let’s verify if any other row might need “Electrical” elsewhere.

Actually, re-examining Row 1: Plugging in a lamp — the plug brings Electrical energy *into* the lamp. Lamp converts it to Light (and some Heat, but Light is primary and listed). That’s solid.

Row 2: Food → body movement = Chemical → Kinetic. Correct.

Row 3: Sun → person feels hot = Radiant → Heat. Yes. (Note: “Light” is a type of radiant energy, but “Radiant” is the broader term used in science for energy from the sun; and “Light” is separately listed, so we reserve “Light” for visible light output like lamps.)

Row 4: Batteries → boombox sound. Batteries store Chemical energy. Boombox outputs Sound. That fits.

But wait — is there a chance the right side of Row 4 should be Electrical? No, because the boombox is *using* electrical energy internally, but the final observable output is sound (and maybe light/heat), and the picture emphasizes the speakers/sound waves. The worksheet expects the *final useful output* energy form.

Also, check word bank: “Stored” is there — could batteries be “Stored”? Technically yes, but “Stored” is vague; science prefers “Chemical” for batteries. “Stored” is probably a distractor or for other contexts (like stored potential energy). We have “Chemical” available and appropriate.

One more check: Is “Mechanical” used anywhere? Mechanical energy = kinetic + potential (e.g., moving parts). The running child is kinetic, not mechanical per se — we use kinetic directly. The lamp isn’t mechanical. Sun isn’t. Boombox has moving speaker parts, but output is sound.

So final assignments:

Row 1: Electrical → Light
Row 2: Chemical → Kinetic
Row 3: Radiant → Heat
Row 4: Chemical → Sound

All words used are in the bank.

Final Answer:
Row 1 left: Electrical, right: Light
Row 2 left: Chemical, right: Kinetic
Row 3 left: Radiant, right: Heat
Row 4 left: Chemical, right: Sound
