Educational worksheet for learning about different forms of energy through reading, matching, and picture identification.

Let's solve each part of this worksheet step by step.

---

1. Read and match:

We are given a list of definitions and need to match them with the correct type of energy from the box:

Energy types:
- Potential energy
- Electrical energy
- Chemical energy
- Heat energy
- Mechanical energy
- Kinetic energy
- Sound energy
- Light energy

Now, let’s match each definition:

1. The energy that a moving object has...
→ Kinetic energy
*(Because kinetic energy is the energy of motion.)*

2. The energy stored in matter...
→ Chemical energy
*(Chemical energy is stored in the bonds of molecules.)*

3. The sum of two other types of energy...
→ Mechanical energy
*(Mechanical energy = Kinetic energy + Potential energy.)*

4. The energy produced by a source of light...
→ Light energy
*(Light energy is emitted by sources like the sun or lamps.)*

5. This is released during chemical reactions...
→ Chemical energy
*(When chemicals react, stored chemical energy is released.)*

6. This energy comes from the movement of electrons...
→ Electrical energy
*(Electrical energy results from moving electrons.)*

7. This energy flows from warmer objects to cooler objects...
→ Heat energy
*(Heat energy transfers from hot to cold objects.)*

8. Vibrations of the air that we detect with our sense of hearing...
→ Sound energy
*(Sound is caused by vibrations in the air.)*

✔ Final Answers for Part 1:

- The energy that a moving object has... → Kinetic energy
- The energy stored in matter... → Chemical energy
- The sum of two other types of energy... → Mechanical energy
- The energy produced by a source of light... → Light energy
- This is released during chemical reactions... → Chemical energy
- This energy comes from the movement of electrons... → Electrical energy
- This energy flows from warmer objects to cooler objects... → Heat energy
- Vibrations of the air that we detect with our sense of hearing... → Sound energy

2. Read and choose the correct forms of energy.

We have a list of situations (a–h) and options (i–ñ). We must match each situation to the correct form of energy.

Let’s go through each:

a. wind in the trees → Wind is moving air → Kinetic energy
→ Matches with n. flowing water? No. Wait — look at the choices on the right:
Actually, the instructions say: "Read and choose the correct forms of energy" and list items a–h and i–ñ. But it seems like we're supposed to match each description (a–h) to one of the options (i–ñ) based on energy type.

Wait — actually, looking carefully:
It says “read and choose the correct forms of energy” and lists:
- a. wind in the trees
- b. noises from machines
- ...
- h. when food is broken down...

And then on the right:
- i. feel the air around you.
- j. a wind turbine in motion.
- k. musical instruments.
- l. water in a reservoir.
- m. when a ball is rolling.
- n. flowing water.
- ñ. sun and stars.

But this seems mismatched. Actually, likely the task is to match each of a–h with an example (i–ñ) that shows the same form of energy.

But more logically, perhaps it's asking: For each of a–h, identify which form of energy it represents, and then pick the matching example from i–ñ?

But the wording is confusing.

Wait — actually, looking again:
It says: “Read and choose the correct forms of energy.” Then lists a–h on the left and i–ñ on the right.

But i–ñ are also examples.

Possibly, the task is to match each item (a–h) to its corresponding energy form, and the options i–ñ are just examples of phenomena that show those energies.

But no — actually, I think the intention is to match each of a–h with one of i–ñ, but they don’t seem to be paired.

Alternatively, maybe the task is to identify the energy type for each of a–h, and then choose the correct option from the list (i–ñ) that matches that energy.

But that doesn't make sense because i–ñ are not labeled with energy types.

Wait — let's re-read:

> 2. Read and choose the correct forms of energy.
> a. wind in the trees.
> b. noises from machines.
> ...
> h. when food is broken down during digestion.
>
> i. feel the air around you.
> j. a wind turbine in motion.
> k. musical instruments.
> l. water in a reservoir.
> m. when a ball is rolling.
> n. flowing water.
> ñ. sun and stars.

Ah! Now I see — this is likely a matching exercise: Match each item on the left (a–h) to the correct example on the right (i–ñ), based on similar energy type.

But that doesn't quite fit either.

Wait — perhaps it's asking: For each phenomenon (a–h), which of the following (i–ñ) is an example of the same energy type?

But that would require knowing what energy each represents.

Let’s assume the goal is: Identify the form of energy for each of a–h, and then match it to a similar example from i–ñ.

But that still doesn't clarify.

Alternatively, maybe it's a list of examples, and we are to choose the correct energy form for each.

But the instruction says “choose the correct forms of energy”, so perhaps we need to write the energy type for each.

But there are no blank lines.

Looking at the format, it seems like the teacher wants us to match each of a–h to one of i–ñ, where both represent the same energy form.

Let’s analyze:

| a. wind in the trees | → Moving air → Kinetic energy |
| b. noises from machines | → Sound → Sound energy |
| c. a person riding a bicycle | → Motion → Kinetic energy |
| d. boiling water on a cooker | → Heat → Thermal energy |
| e. lamps and torches | → Light → Light energy |
| f. lightning in a storm | → Electricity → Electrical energy |
| g. batteries generating electricity | → Electrical energy → Electrical energy |
| h. when food is broken down during digestion | → Chemical energy released → Chemical energy |

Now look at the options on the right:

- i. feel the air around you → feels like wind → Kinetic energy
- j. a wind turbine in motion → Kinetic energy (and electrical)
- k. musical instruments → Sound energy
- l. water in a reservoir → Potential energy (gravitational)
- m. when a ball is rolling → Kinetic energy (and some potential)
- n. flowing water → Kinetic energy
- ñ. sun and stars → Light and thermal energy

Now, match a–h to i–ñ based on energy:

- a. wind in the trees → i. feel the air around you (both involve moving air → kinetic)
- b. noises from machines → k. musical instruments (both produce sound)
- c. a person riding a bicycle → m. when a ball is rolling (both are moving objects → kinetic)
- d. boiling water on a cooker → n. flowing water? No — boiling is heat → better match: ñ. sun and stars? No, too broad. Maybe none directly.

Wait — perhaps the idea is to match each of a–h to one of i–ñ, but only if they share the same energy.

But many don't match well.

Alternative interpretation: Perhaps the list i–ñ are examples of energy types, and we are to match each of a–h to the correct energy type from i–ñ.

But that doesn’t make sense.

Wait — perhaps the task is: For each of a–h, choose the letter (i–ñ) that represents the same form of energy.

So:

- a. wind in the trees → i. feel the air around you (both kinetic)
- b. noises from machines → k. musical instruments (both sound)
- c. a person riding a bicycle → j. a wind turbine in motion or m. when a ball is rolling → both kinetic
- d. boiling water on a cooker → n. flowing water? No — boiling is heat → ñ. sun and stars? Sun produces heat, yes — but not perfect.
- e. lamps and torches → ñ. sun and stars (both emit light)
- f. lightning in a storm → g. batteries generating electricity? But g is listed as a separate item. Wait — g is on the left.

Wait — now I realize: The list a–h are the phenomena, and i–ñ are other examples. So the task is to match each of a–h to one of i–ñ that demonstrates the same type of energy.

So:

- a. wind in the trees → i. feel the air around you → both involve moving air → kinetic energy
- b. noises from machines → k. musical instruments → both produce sound energy
- c. a person riding a bicycle → m. when a ball is rolling → both are kinetic energy
- d. boiling water on a cooker → n. flowing water? No — boiling is heat/thermal energy → ñ. sun and stars? Sun emits heat, but not direct match. Better: l. water in a reservoir? No, that’s potential. Not good.

Wait — perhaps d. boiling water → i. feel the air around you? No.

Another idea: Maybe d. boiling water → n. flowing water? No — different.

Wait — perhaps d. boiling water → ñ. sun and stars? Sun heats things, but not direct.

Alternatively, d. boiling water → l. water in a reservoir? No.

Wait — perhaps d. boiling water → n. flowing water? Still no.

Maybe d. boiling water → i. feel the air around you? If the air is hot, yes — but not clear.

Perhaps the best matches are:

- a. wind in the trees → i. feel the air around you (kinetic)
- b. noises from machines → k. musical instruments (sound)
- c. a person riding a bicycle → m. when a ball is rolling (kinetic)
- d. boiling water on a cooker → ñ. sun and stars? Sun heats Earth → thermal energy → yes, both involve thermal energy
- e. lamps and torches → ñ. sun and stars → both emit light energy
- f. lightning in a storm → g. batteries generating electricity → both involve electrical energy
- g. batteries generating electricity → f. lightning in a storm → both electrical
- h. when food is broken down → l. water in a reservoir? No — food has chemical energy → ñ. sun and stars? Sun provides energy for food via photosynthesis → but not direct.

Wait — this is messy.

Let’s try a better approach: Assign energy type to each of a–h:

- a. wind in the trees → kinetic energy
- b. noises from machines → sound energy
- c. a person riding a bicycle → kinetic energy
- d. boiling water on a cooker → thermal energy
- e. lamps and torches → light energy
- f. lightning in a storm → electrical energy
- g. batteries generating electricity → electrical energy
- h. food digestion → chemical energy

Now assign energy type to i–ñ:

- i. feel the air around you → kinetic energy (moving air)
- j. a wind turbine in motion → kinetic energy (and mechanical)
- k. musical instruments → sound energy
- l. water in a reservoir → potential energy
- m. when a ball is rolling → kinetic energy
- n. flowing water → kinetic energy
- ñ. sun and stars → light and thermal energy

Now match:

- a. wind in the trees → i (kinetic)
- b. noises from machines → k (sound)
- c. a person riding a bicycle → j or m or n → any kinetic → j (wind turbine) is a good example of kinetic energy
- d. boiling water → ñ (sun and stars) — both produce heat → thermal energy
- e. lamps and torches → ñ (sun and stars) — both emit light → light energy
- f. lightning → g? But g is on the left. Wait — g is "batteries generating electricity", which is also electrical.

So f and g both involve electrical energy → so f → g? But g is not on the right.

Wait — the right side is i–ñ, so:

- f. lightning → g is not on the right. So which of i–ñ is electrical?

None explicitly. But ñ. sun and stars produce light and heat, but also have electrical activity? Not really.

Wait — perhaps j. a wind turbine in motion → converts kinetic to electrical → but it’s not electrical itself.

No good match.

Alternatively, maybe the task is to write the energy type for each of a–h, but the worksheet has no blanks.

Given the confusion, perhaps the intended answer is to match a–h to i–ñ based on similar energy:

- a. wind in the trees → i. feel the air around you (both involve air movement)
- b. noises from machines → k. musical instruments (both produce sound)
- c. a person riding a bicycle → m. when a ball is rolling (both moving objects)
- d. boiling water → n. flowing water? No — boiling is heat → l. water in a reservoir? No — potential.

Wait — d. boiling water → i. feel the air around you? If the air is hot, yes — but not strong.

Perhaps d. boiling water → ñ. sun and stars (both produce heat)

Similarly, e. lamps and torches → ñ. sun and stars (both light)

f. lightning → ñ. sun and stars (lightning is electrical discharge, sun has solar flares)

g. batteries generating electricity → ñ. sun and stars? Sun generates energy, but not electrical directly.

This is not working.

Alternative idea: Perhaps the list i–ñ are examples of energy types, and we are to choose the correct energy form for a–h, but the answer choices are i–ñ.

But i–ñ are descriptions, not energy names.

I think there might be a formatting issue.

Perhaps the task is: Match each of a–h to one of i–ñ that is an example of the same energy.

Best guesses:

- a. wind in the trees → i. feel the air around you (kinetic)
- b. noises from machines → k. musical instruments (sound)
- c. a person riding a bicycle → m. when a ball is rolling (kinetic)
- d. boiling water on a cooker → n. flowing water? No — boiling is heat → ñ. sun and stars (thermal)
- e. lamps and torches → ñ. sun and stars (light)
- f. lightning in a storm → ñ. sun and stars (electrical discharge)
- g. batteries generating electricity → ñ. sun and stars (but not exact)
- h. food digestion → l. water in a reservoir? No — chemical energy

Wait — l. water in a reservoir → potential energy

h. food digestion → chemical energy

No match.

Perhaps h. food digestion → ñ. sun and stars (because sun provides energy for plants, which we eat)

But that's indirect.

Given the ambiguity, let's skip and move to Part 3, which is clearer.

3. Match the forms of energy to the pictures.

We have five pictures:

- a. A wind turbine produces...
→ Wind turbine converts wind (kinetic) into electricity → kinetic and electrical energy

- b. A radiator produces...
→ Radiator heats the room → thermal energy (heat)

- c. A candle produces...
→ Candle gives off light and heat → light and thermal energy

- d. A girl produces...
→ Girl running → moving → kinetic energy, and her body produces heat → thermal energy → kinetic and thermal energy

- e. A cymbals produce...
→ Cymbals make sound → sound energy

Now, match to the boxes:

Available options:
- sound energy
- kinetic and thermal energy
- light and thermal energy
- kinetic and electrical energy
- thermal energy

So:

- a. wind turbine → kinetic and electrical energy
- b. radiator → thermal energy
- c. candle → light and thermal energy
- d. girl → kinetic and thermal energy
- e. cymbals → sound energy

✔ Final Answers for Part 3:

- a. A wind turbine produces... → kinetic and electrical energy
- b. A radiator produces... → thermal energy
- c. A candle produces... → light and thermal energy
- d. A girl produces... → kinetic and thermal energy
- e. A cymbals produce... → sound energy

Summary of Answers

#### 1. Read and match:

1. The energy that a moving object has... → Kinetic energy
2. The energy stored in matter... → Chemical energy
3. The sum of two other types of energy... → Mechanical energy
4. The energy produced by a source of light... → Light energy
5. This is released during chemical reactions... → Chemical energy
6. This energy comes from the movement of electrons... → Electrical energy
7. This energy flows from warmer objects to cooler objects... → Heat energy
8. Vibrations of the air that we detect with our sense of hearing... → Sound energy

#### 2. Read and choose the correct forms of energy.

Given the confusion, here’s the most logical matching:

- a. wind in the trees → i. feel the air around you (both kinetic)
- b. noises from machines → k. musical instruments (both sound)
- c. a person riding a bicycle → m. when a ball is rolling (both kinetic)
- d. boiling water on a cooker → ñ. sun and stars (both thermal)
- e. lamps and torches → ñ. sun and stars (both light)
- f. lightning in a storm → ñ. sun and stars (both electrical/light)
- g. batteries generating electricity → ñ. sun and stars (indirectly)
- h. when food is broken down during digestion → l. water in a reservoir? No — better: ñ. sun and stars (sun provides energy for food)

But this is not ideal.

Alternatively, perhaps the task is simply to identify the energy type for each of a–h:

- a. kinetic energy
- b. sound energy
- c. kinetic energy
- d. thermal energy
- e. light energy
- f. electrical energy
- g. electrical energy
- h. chemical energy

But since the worksheet asks to "choose" from i–ñ, and i–ñ are examples, it’s likely a matching exercise.

Given the ambiguity, I’ll provide the best possible matching:

| a | i |
|---|---|
| b | k |
| c | m |
| d | ñ |
| e | ñ |
| f | ñ |
| g | ñ |
| h | ñ |

But this repeats ñ.

Alternatively, perhaps:

- a. i
- b. k
- c. j or m
- d. n? No — boiling is heat
- e. ñ
- f. ñ
- g. ñ
- h. ñ

Still not great.

Perhaps the task is to match a–h to the correct energy type, and the i–ñ are distractors.

But without clear instructions, I'll focus on Part 1 and 3, which are clear.

If you can clarify Part 2, I’d be happy to refine it.
