Sources of Light - ESL worksheet by monika.79 - Free Printable

Let’s solve this step by step.

We have two parts:

Part 1: Match the pictures to the numbers (Sources of Light)
We are given 10 pictures and a list of 10 light sources with numbers. We need to write the correct number next to each picture.

Looking at the pictures (from top left, going row by row):

1. Wall lamp → looks like a lamp mounted on a wall with two lights → that’s #7
2. Torch (flashlight) → handheld, battery-powered → that’s #10
3. Lantern → red, old-style with handle → that’s #4
4. Candle → wax with flame → that’s #3
5. Bedside lamp → small lamp on table, yellow shade → that’s #6
6. Lamppost → tall street light → that’s #5
7. Bulb → just the glass bulb part → that’s #8
8. The Sun → bright yellow sun → that’s #2
9. Matches → box with matchstick sticking out → that’s #1
10. Chandelier → hanging from ceiling with multiple arms → that’s #9

So for Part 1, the numbers next to each picture (in order as shown) are:
- Wall lamp → 7
- Torch → 10
- Lantern → 4
- Candle → 3
- Bedside lamp → 6
- Lamppost → 5
- Bulb → 8
- The Sun → 2
- Matches → 1
- Chandelier → 9

But note — the instruction says “write the number next to each picture” — so we don’t need to list them again unless asked. Since the user didn’t ask to fill in the blanks visually, and the main task seems to be solving the riddles (which use those same items), let’s move to Part 2.

---

Part 2: Solve the riddles

Each riddle describes one of the light sources. We must match the riddle number (1 to 10) to the correct word from the list on the right.

List of words (right side):
- matches
- the Sun
- a candle
- a lantern
- a lamppost
- a bedside lamp
- a wall lamp
- a bulb
- a chandelier

Now solve each riddle:

Riddle 1: “It’s a small object powered by batteries which you keep in your hand.”
→ That’s a torch or flashlight. But “torch” is not in the right-side list? Wait — look back: In the first part, “a torch” was #10. But in the riddle answer choices on the right, “a torch” is NOT listed! Hmm... Let me check again.

Wait — actually, looking at the image description: On the right side under “Solve the riddles”, there are 10 boxes with arrows pointing to words. The words listed are:

From top to bottom:
- matches
- the Sun
- a candle
- a lantern
- a lamppost
- a bedside lamp
- a wall lamp
- a bulb
- a chandelier

That’s only 9 words? No — wait, let me count again from the original problem text provided:

In the user's message, under “Solve the riddles”, after the 10 riddle boxes, on the right it says:

```
matches
the Sun
a candle
a lantern
a lamppost
a bedside lamp
a wall lamp
a bulb
a chandelier
```

That’s 9 items. But there are 10 riddles. Oh — I see! In the initial list (top right box), there are 10 items including “a torch”. And in the riddle section, perhaps “a torch” is implied? Or maybe I miscounted.

Wait — let’s re-read the user’s input carefully.

Actually, in the “Solve the riddles” section, the right-hand column has 10 entries? Let me recount based on standard layout.

Looking at typical worksheets: Usually, for 10 riddles, there are 10 answers. In the top-right box, we have:

1- matches
2- the Sun
3- a candle
4- a lantern
5- a lamppost
6- a bedside lamp
7- a wall lamp
8- a bulb
9- a chandelier
10- a torch

And in the riddle-solving section, the right-side list likely includes all 10, but in the text you pasted, you wrote only 9. However, since Riddle 1 clearly refers to a torch (battery-powered, handheld), and “torch” is item #10 in the master list, we’ll assume the answer choices include “a torch” even if not explicitly typed in your message — because otherwise Riddle 1 has no answer.

Alternatively, perhaps in the actual image, the right-side list for riddles includes “a torch” as the last item. Given that, let’s proceed logically.

Let’s solve each riddle using common sense and the master list:

Riddle 1: “small object powered by batteries which you keep in your hand” → torch (#10)

Riddle 2: “transparent case usually made of glass which you keep in your hands” → This sounds like a lantern? But lanterns aren't always held in hands... Wait — could it be a bulb? No, bulbs aren’t kept in hands. Actually, some lanterns are handheld. But let’s think: “transparent case... glass... keep in your hands” — maybe it’s describing a glass lantern? Yes, likely lantern (#4). But wait — another possibility: Is there a “glass object you screw into a lamp”? That’s Riddle 10. So Riddle 2 might be lantern.

Hold on — let’s do them all systematically.

Better approach: Use elimination.

Make a table:

Riddle | Description | Likely Answer | Number from master list
---|---|---|---
1 | small, battery-powered, handheld | torch | 10
2 | transparent glass case, kept in hands | lantern (some are handheld glass ones) | 4
3 | lamp with branches, hangs from ceiling | chandelier | 9
4 | lamp that stands in a street | lamppost | 5
5 | piece of wax burned for light | candle | 3
6 | small lamp next to bed | bedside lamp | 6
7 | small wood lit by striking against box | matches | 1
8 | small lamp that hangs on wall | wall lamp | 7
9 | star in center of solar system | the Sun | 2
10 | small glass object screwed into lamp | bulb | 8

Yes! That fits perfectly.

Now, verify:

- Riddle 1: torch → #10 ✔️
- Riddle 2: lantern → #4 ✔️ (handheld glass lanterns exist)
- Riddle 3: chandelier → #9 ✔️
- Riddle 4: lamppost → #5 ✔️
- Riddle 5: candle → #3 ✔️
- Riddle 6: bedside lamp → #6 ✔️
- Riddle 7: matches → #1 ✔️
- Riddle 8: wall lamp → #7 ✔️
- Riddle 9: the Sun → #2 ✔️
- Riddle 10: bulb → #8 ✔️

Perfect — all match, and we used all 10 items exactly once.

So the answers for the riddles (riddle number → word) are:

1 → torch
2 → lantern
3 → chandelier
4 → lamppost
5 → candle
6 → bedside lamp
7 → matches
8 → wall lamp
9 → the Sun
10 → bulb

But the worksheet asks to draw lines or write the word next to each riddle box. Since we’re providing final answer, we can list the matched pairs.

However, note: In the riddle section, the right-hand column probably lists the words in random order, and we assign each riddle to the correct word.

Since the user didn’t specify format, but the task is to “solve the riddles”, meaning match each riddle number to the correct term.

Final Answer should reflect the solution to the riddles, as that’s the active task (“Solve the riddles”).

Also, for Part 1 (matching pictures to numbers), since it says “write the number next to each picture”, and we’ve identified them, but unless the user asks to output those, and since the riddles are the main puzzle, I’ll focus on the riddles for Final Answer.

But to be thorough — let’s confirm what the user wants. The upload contains both tasks, but the instruction is to “solve the problem accurately”. Since both are present, and the riddles require reasoning, while the picture matching is straightforward labeling, perhaps both are expected.

However, looking at the structure: The “Solve the riddles” section has numbered boxes (1 to 10) and then a list of words to choose from. So the expected output is likely: for each riddle number, which word it corresponds to.

Similarly, for the first part, it’s “write the number next to each picture” — so if we were filling the sheet, we’d put numbers beside images. But since we can’t draw, and the user may expect textual answer, perhaps we list the riddle solutions.

Given that, and to avoid confusion, I’ll provide the riddle answers as the primary solution, since they involve deduction.

But let’s double-check Riddle 2: “It’s a transparent case usually made of glass which you keep in your hands.”

Is that really a lantern? Some lanterns are metal. But traditional oil lanterns often have glass cases and can be carried. Alternatively, could it be something else? What about a “candle holder”? Not in list. Or “matches”? No. “Bulb”? Not kept in hands. “Chandelier”? Too big. So yes, lantern is best fit.

Another thought: Could “transparent case... glass... keep in your hands” refer to a light bulb? But bulbs are screwed in, not typically “kept in your hands” as a source of light — you hold them when installing, but not while using. Whereas a lantern you carry around.

Also, Riddle 10 specifically says “small glass object which you screw in the lamp” — that’s definitely the bulb. So Riddle 2 cannot be bulb.

Thus, our mapping is solid.

Final Answer will be the solved riddles: which word goes with which riddle number.

To present clearly:

Riddle 1: a torch
Riddle 2: a lantern
Riddle 3: a chandelier
Riddle 4: a lamppost
Riddle 5: a candle
Riddle 6: a bedside lamp
Riddle 7: matches
Riddle 8: a wall lamp
Riddle 9: the Sun
Riddle 10: a bulb

Note: For Riddle 7, it says “matches” (plural), and in the list it’s “matches” without article, so we keep it as is.

Similarly, “the Sun” has “the”, others have “a” or none.

So in final answer, we write exactly as per the word list.
