Let's solve the worksheet step by step.

Worksheet: Forms of Energy
Direction: Identify the form of energy and match each image to the correct type of energy.
We have six images on the left and six types of energy on the right. We need to match each image with the correct form of energy.
---
Step-by-Step Matching:
1.
Image: Campfire (logs burning with flames)
- This shows fire, which produces
heat and
light.
- The most direct form here is
heat energy.
-
✔ Match:
Heat energy
2.
Image: Electric fan
- A fan uses electricity to move its blades, producing motion.
- This is
mechanical energy (motion).
-
✔ Match:
Mechanical energy
3.
Image: Person pushing a cabinet
- The person is applying force to move an object — this involves physical movement.
- This is
mechanical energy (kinetic energy due to motion).
-
✔ Match:
Mechanical energy
4.
Image: Sun
- The sun emits
light and
heat, but primarily it is known for
light energy.
-
✔ Match:
Light energy
5.
Image: Guitar
- When played, a guitar produces
sound through vibrating strings.
-
✔ Match:
Sound energy
6.
Image: Battery
- A battery stores energy in chemical form and provides
electric energy when used.
-
✔ Match:
Electric energy

Final Matches:
| Image | Form of Energy |
|-------|----------------|
| 🔥 Campfire | Heat energy |
| 🌀 Fan | Mechanical energy |
| 👩🦰 Pushing cabinet | Mechanical energy |
| ☀️ Sun | Light energy |
| 🎸 Guitar | Sound energy |
| 🔋 Battery | Electric energy |
> Note: "Chemical energy" is listed as one of the options, but none of the images directly show a chemical reaction storing energy (like food or fuel). However, the
battery contains
chemical energy, which is converted into
electric energy. But since the question asks to identify the *form of energy* associated with the image, and the battery is typically associated with
electric energy output, we match it accordingly.
But let’s clarify:
- The
battery stores
chemical energy but releases
electric energy.
- Since the image is of a battery with a lightning bolt (⚡), it emphasizes
electric energy.
- So, the best match is
electric energy.
However, if the prompt allows for
stored vs.
used energy, then:
- Battery →
Chemical energy (stored)
- But based on common educational contexts and the visual cue (⚡), it's usually matched to
electric energy.
✔ Therefore,
battery → electric energy.

✔ Final Answer:
1. Campfire →
Heat energy
2. Fan →
Mechanical energy
3. Person pushing cabinet →
Mechanical energy
4. Sun →
Light energy
5. Guitar →
Sound energy
6. Battery →
Electric energy

⚠️ Note:
The option
"chemical energy" is not used in this matching, but it's still a valid form of energy. In real life, the
campfire also involves
chemical energy (from wood combustion), but the visible output is
heat and light. So,
heat energy is the most appropriate choice for that image.
