Educational worksheet on types of energy featuring matching terms with definitions and identifying energy types in real-life scenarios.

Let’s solve this step by step.

---

Part 1: Match each term with the correct definition.

We have 6 energy types and 6 definitions. Let’s match them one by one using what we know about energy:

- Thermal energy → This is heat energy. So it matches:
→ *Energy that produces heat.*

- Light energy → This is energy from light (like lamps, sun). So:
→ *Energy that produces light.*

- Chemical energy → Stored in things like food, batteries, fuel. So:
→ *Energy stored in food and living things.*

- Electrical energy → Comes from moving electric charges (like in wires or outlets). So:
→ *Energy that comes from the flow of electric charge.*

- Kinetic energy → Energy of motion. If something is moving, it has kinetic energy. So:
→ *Energy that an object possesses because of its motion.*

- Sound energy → Made by vibrations that travel through air (or other materials) as sound waves. So:
→ *Energy that produces sound.*

✔ All matched correctly!

Part 2: Choose the appropriate ‘type of energy’ in each picture.

Now let’s look at each item and think: What kind of energy does it mainly use or produce?

1. Flashlight → It turns electrical energy (from batteries) into light. So main output = Light energy

2. TV → Uses electricity to make pictures (light) and sound. But since we’re picking one type per item, and TVs are known for showing images, we’ll go with Light energy — but wait! Actually, many teachers accept “electrical” as input, but the question says “type of energy IN each picture” — meaning what energy form is being used or shown? Since TV uses electricity to work, and also gives off light and sound… Hmm. Let’s check common school answers: Usually, for TV, they say Electrical energy (because it plugs in) OR sometimes Light + Sound. But since we must pick ONE, and looking at context — Flashlight is clearly Light, Radio is Sound, so TV might be Electrical? Wait — no, let’s rethink.

Actually, let’s list all items again and assign based on PRIMARY function or energy form involved:

- Flashlight → Makes light → Light energy
- TV → Uses electricity to show video/audio → Most accurate single answer: Electrical energy (since it needs power to run), BUT some curricula say “light and sound”. However, since we can only choose one, and comparing to others — let’s see standard matching: In most elementary science, TV is associated with Electrical energy because it runs on electricity.
Wait — actually, let me double-check with logic: The question says “choose the appropriate ‘type of energy’ in each picture.” That could mean what energy is being converted or displayed.

But here’s a better way: Think about what energy you GET from the device:

- Flashlight → gives you LIGHT → Light energy
- TV → gives you LIGHT (pictures) and SOUND → but if forced to pick one, perhaps Light? Or maybe Electrical? Let’s hold and do others first.

3. Radio → Plays music/speech → makes SOUND → Sound energy

4. Fuel (gas pump) → Gasoline stores chemical energy → when burned, releases energy → so Chemical energy

5. Radiator → Heats up room → gives off HEAT → Thermal energy

6. Ride a bike → Person pedaling → movement → Kinetic energy

Now back to TV: What’s the best fit? Since flashlight is already taking “light”, and radio takes “sound”, then TV should probably take Electrical energy, because it requires electricity to operate — even though it outputs light and sound, the source is electrical. Also, in many textbooks, devices like TVs, computers, etc., are labeled under “electrical energy”.

Alternatively, if the worksheet expects the OUTPUT energy, then TV would be light or sound — but since both flashlight and radio are output-based (light and sound respectively), maybe TV should be... hmm.

Wait — let’s count how many times each energy type appears in Part 1:

From Part 1 matches:
- Thermal → heat
- Light → light
- Chemical → food/living
- Electrical → flow of charge
- Kinetic → motion
- Sound → sound

In Part 2, we have 6 items. We need to assign one energy type per item, likely reusing the same six terms.

So let’s map:

- Flashlight → Light energy ✔
- TV → ?
- Radio → Sound energy ✔
- Fuel → Chemical energy ✔
- Radiator → Thermal energy ✔
- Ride a bike → Kinetic energy ✔

That leaves TV → must be Electrical energy

Yes! Because all other five are taken, and TV runs on electricity. Perfect.

Final assignments:

- Flashlight → Light energy
- TV → Electrical energy
- Radio → Sound energy
- Fuel → Chemical energy
- Radiator → Thermal energy
- Ride a bike → Kinetic energy

This uses all six energy types exactly once — which makes sense for a matching exercise.
