Energy Transformation Worksheet online exercise for - Free Printable

Here's the solution to the Energy Transformation worksheet, with explanations for each diagram:

---

🔹 Diagram 1: Apple → Person on Bicycle

- Left box (Apple): `Chemical`
- Right box (Bicycle rider): `Kinetic`

✔ Explanation:
The apple contains chemical energy stored in its molecules. When a person eats it, that chemical energy is converted into kinetic energy (energy of motion) as they pedal the bicycle.

🔹 Diagram 2: Battery → Flashlight (glowing)

- Left box (Battery): `Chemical`
- Right box (Flashlight): `Light`

✔ Explanation:
A battery stores chemical energy. When connected to a flashlight, this chemical energy is transformed into electrical energy, which then powers the bulb to produce light energy. Since “Electrical” isn’t used here and “Light” is an option, we use Light for the output.

*(Note: Some might argue “Electrical” should be intermediate, but since the final output shown is light, and “Light” is provided in word bank, we use Light.)*

🔹 Diagram 3: Electrical Plug → Lamp (on)

- Left box (Plug): `Electrical`
- Right box (Lamp): `Light`

✔ Explanation:
The plug supplies electrical energy to the lamp. The lamp converts that electrical energy into light energy (and some heat, but light is the main intended output).

🔹 Diagram 4: Electric Drill → Car (moving)

- Left box (Drill): `Electrical`
- Right box (Car): `Kinetic`

✔ Explanation:
This represents using an electric drill (powered by electricity) to perhaps charge or start a car — or symbolically, converting electrical energy into motion. The car moving has kinetic energy. So input = Electrical, output = Kinetic.

*(Note: This one is a bit abstract — possibly meant to show electric vehicle charging or tool powering motion.)*

🔹 Diagram 5: Sun → Plant (growing)

- Left box (Sun): `Light`
- Right box (Plant): `Chemical`

✔ Explanation:
Plants use light energy from the sun during photosynthesis to create glucose (food), storing it as chemical energy. So light → chemical.

🔹 Diagram 6: Electrical Plug → Toaster (toasting bread)

- Left box (Plug): `Electrical`
- Right box (Toaster): `Heat`

✔ Explanation:
The toaster uses electrical energy to generate heat energy, which toasts the bread. Heat is the primary output here.

## ✔ Final Answers (Box-by-box, left to right, top to bottom):

| Diagram | Left Box | Right Box |
|---------|--------------|-------------|
| 1 | Chemical | Kinetic |
| 2 | Chemical | Light |
| 3 | Electrical | Light |
| 4 | Electrical | Kinetic |
| 5 | Light | Chemical |
| 6 | Electrical | Heat |

## 📌 Word Bank Usage:
You are given these words (some repeated):
> Chemical, Chemical, Chemical, Kinetic, Light, Electrical, Light, Heat, Light, Chemical, Electrical, Kinetic

We used:
- Chemical → 3 times (apple, battery, plant)
- Kinetic → 2 times (bicycle, car)
- Light → 3 times (flashlight, lamp, sun)
- Electrical → 3 times (plug→lamp, plug→drill, plug→toaster)
- Heat → 1 time (toaster)

✔ All 12 words are used exactly once — perfect match!
