Students identify items that produce thermal energy by placing checkmarks on the correct images.

Let's solve this Thermal Energy worksheet step by step.

🔍 What is Thermal Energy?

Thermal energy is the energy produced by heat. It is the internal energy of a system due to the movement of particles (atoms or molecules). Objects that are hot or produce heat have thermal energy.

We need to identify which of the items in the image produce or involve thermal energy.

✔ Let’s go through each item:

1. Frying pan on a stove with food cooking
→ The stove heats the pan, and food is being cooked.
✔️ Produces thermal energy → Checkmark

2. Flower
→ A flower does not produce heat. It may absorb sunlight but doesn't generate thermal energy.
✘ No

3. Campfire
→ Fire produces intense heat.
✔️ Produces thermal energy → Checkmark

4. Cup of coffee (steaming)
→ Steam indicates hot liquid; it has thermal energy.
✔️ Contains thermal energy → Checkmark

5. Guitar
→ A musical instrument. No heat production involved.
✘ No

6. Toaster oven with a pie baking
→ Oven heats up to cook food.
✔️ Produces thermal energy → Checkmark

7. Ice cubes
→ Cold objects. They absorb heat (they don’t produce thermal energy).
✘ No

8. Kettle boiling water
→ Water is heated, steam is rising — clear sign of thermal energy.
✔️ Produces thermal energy → Checkmark

9. Eyeglasses
→ No heat involved.
✘ No

✔ Final Answers (Items that produce thermal energy):

- Frying pan on stove
- Campfire
- Cup of coffee
- Toaster oven
- Kettle

👉 So, checkmarks should be placed in the circles under:
1. Frying pan
2. Campfire
3. Coffee cup
4. Toaster oven
5. Kettle

📝 Summary:

Thermal energy is produced when something generates heat.
The correct items are those involving fire, cooking, boiling, or hot objects.

✔ Check these:
- Frying pan
- Campfire
- Coffee cup
- Toaster oven
- Kettle

✘ Leave blank:
- Flower
- Guitar
- Ice cubes
- Eyeglasses
