Forms of energy activity for 4th - Free Printable

Absolutely! Let’s solve this “Forms of Energy” worksheet step by step. The goal is to match each diagram with the correct form of energy that is being used (input) and the form of energy that is being produced (output).

We are given a word bank:

> Chemical, Chemical, Chemical, Mechanical, Light, Electrical, Light, Heat, Light, Chemical, Electrical, Mechanical

Note: Some words are repeated — that’s okay, because some energy conversions use the same type more than once.

🍎 1. Apple → Person on bicycle

- An apple contains chemical energy (stored in food).
- When you eat it, your body converts that chemical energy into mechanical energy to move your muscles and pedal the bike.
✔ Input: Chemical
✔ Output: Mechanical

---

🔋 2. Battery → Flashlight (emitting light)

- A battery stores chemical energy.
- It converts that into electrical energy, which powers the flashlight to produce light.
✔ Input: Chemical
✔ Output: Light

---

🔌 3. Plug → Lamp (glowing)

- The plug connects to an electrical source → so input is electrical energy.
- The lamp converts electricity into light (and some heat, but here we focus on the main output: light).
✔ Input: Electrical
✔ Output: Light

---

🔋 4. Battery → Toy car (moving)

- Again, battery = chemical energy stored.
- Converted to electrical energy to power the motor, which produces mechanical energy (movement).
✔ Input: Chemical
✔ Output: Mechanical

---

☀️ 5. Sun → Plant (growing)

- The sun emits light energy.
- Plants use photosynthesis to convert light energy into chemical energy (stored in glucose/sugars).
✔ Input: Light
✔ Output: Chemical

---

🔌 6. Plug → Toaster (toasting bread)

- Plug = electrical energy input.
- Toaster converts electricity into heat energy to toast the bread.
✔ Input: Electrical
✔ Output: Heat

## ✔ Final Answers (Left to Right, Top to Bottom):

Row 1:
- Apple → Bicycle: Chemical → Mechanical
- Battery → Flashlight: Chemical → Light

Row 2:
- Plug → Lamp: Electrical → Light
- Battery → Car: Chemical → Mechanical

Row 3:
- Sun → Plant: Light → Chemical
- Plug → Toaster: Electrical → Heat
