This worksheet asks you to identify the correct
source of energy for each item in the yellow column.
Let’s go row by row and match each item with its most direct or primary source of energy from the options given:
---
1. Electric Fan
-
Options: electricity, food, sunlight
-
✔ Correct Answer: electricity
- An electric fan runs on electrical power — it plugs into an outlet or uses a battery (which stores electricity). It doesn’t run on food or sunlight directly.
---
2. Remote Control
-
Options: sunlight, batteries, food
-
✔ Correct Answer: batteries
- Most remote controls are powered by batteries. While some solar-powered remotes exist, the standard one shown here uses batteries. Sunlight and food are not relevant.
---
3. Plant
-
Options: batteries, sunlight, electricity
-
✔ Correct Answer: sunlight
- Plants use
sunlight for photosynthesis to make their own food. This is their primary energy source. They don’t use batteries or electricity.
---
4. People
-
Options: food, electricity, batteries
-
✔ Correct Answer: food
- Humans get energy from eating
food, which our bodies convert into usable energy. Electricity and batteries aren’t direct sources of human energy.
---
5. Robot
-
Options: electricity, food, sunlight
-
✔ Correct Answer: electricity
- Robots are machines that typically run on
electricity — either from batteries or being plugged in. They don’t eat food or absorb sunlight as their main energy source (unless specifically solar-powered, but the image shows a general robot).

✔ Final Answers:
| Item | Source of Energy |
|---------------|------------------|
| Electric Fan | electricity |
| Remote Control| batteries |
| Plant | sunlight |
| People | food |
| Robot | electricity |
---
✔ Summary Explanation:
Each object gets energy from a specific source:
- Machines like fans and robots →
electricity
- Battery-powered devices →
batteries
- Living things (plants & people) →
sunlight (for plants via photosynthesis) and
food (for humans)
This helps children understand how different things in the world get the energy they need to function!
