Let's solve the "Transforming Energy" worksheet step by step. The goal is to identify the
form of energy before and
after each energy conversion shown in the images.
---
🔹 1. Gas Pump → Car
-
Before (left side): A gas pump is dispensing fuel into a car.
- The fuel (gasoline) stores
chemical energy.
-
After (right side): The car is moving, emitting exhaust.
- The car’s engine converts chemical energy into
mechanical energy (motion).
✔ Answer:
- Before:
Chemical Energy
- After:
Mechanical Energy
---
🔹 2. Battery → Flashlight
-
Before (left side): A battery.
- Batteries store energy in
chemical form.
-
After (right side): A flashlight is turned on, emitting light.
- The battery powers the flashlight, converting energy into
light energy.
✔ Answer:
- Before:
Chemical Energy
- After:
Light Energy
---
🔹 3. Electric Kettle → Cup of Hot Coffee
-
Before (left side): An electric kettle plugged in and heating water.
- Electricity is being used — so
electrical energy is input.
-
After (right side): A cup of hot coffee (steaming).
- The water has been heated, so the energy is now
thermal energy (heat).
✔ Answer:
- Before:
Electrical Energy
- After:
Thermal Energy

✔ Final Answers:
| Image | Before | After |
|------|--------|-------|
| Gas Pump → Car | Chemical Energy | Mechanical Energy |
| Battery → Flashlight | Chemical Energy | Light Energy |
| Kettle → Coffee | Electrical Energy | Thermal Energy |

This worksheet teaches how energy changes form during everyday processes. Each transformation follows the law of conservation of energy — energy is not destroyed, just converted from one form to another!
Parent Tip: Review the logic above to help your child master the concept of energy transformation worksheet.
