Educational worksheet on the properties of metals and non-metals, featuring multiple-choice and fill-in-the-blank exercises with images of cooking pots, bridges, mirrors, and jewelry.

Explanation:
Let’s solve each part step by step.

Part 1: Tick the box for Metal or Non-metal

We need to decide whether each property usually applies to metals, non-metals, both, or neither — but the question says “tick the box to show if the property described applies to metals and/or non-metals.” So for each statement, we tick Metal, Non-metal, or possibly both — but looking at the options, it seems each row has two boxes (Metal / Non-metal), and we tick only the correct one(s). Let’s analyze each:

a) *Most are good conductors of electricity.*
→ Metals are good conductors (e.g., copper, silver). Non-metals are generally poor (except graphite). So this applies to Metal.

b) *Most are flexible solids.*
→ Metals are malleable and ductile — they can bend without breaking (flexible solids). Non-metals like sulfur or phosphorus are brittle. So Metal.

c) *Most are shiny when polished.*
→ Metals have luster; when polished, they shine (e.g., silver, gold). Non-metals are dull (except iodine crystals, but “most” → metal). So Metal.

d) *Tend to be brittle solids that break rather than bend.*
→ This is typical of non-metals (e.g., sulfur, carbon in solid form like coal). Metals bend, not break. So Non-metal.

e) *Mostly poor conductors of heat.*
→ Non-metals are poor conductors of heat (e.g., wood, plastic, sulfur). Metals are good conductors. So Non-metal.

f) *All but one are solids at room temperature.*
→ At room temp: most metals are solids (only mercury is liquid). Most non-metals: gases (O₂, N₂), one liquid (bromine), rest solids (S, P, C). So “all but one are solids” fits Metals (only Hg is liquid). For non-metals, there are *more* than one non-solid (gases + bromine), so this does not describe non-metals. So Metal.

g) *Some are gases.*
→ Non-metals include gases: O₂, N₂, F₂, Cl₂ (gas at room temp), etc. Metals are never gases at room temp. So Non-metal.

So Part 1 answers:
a: Metal
b: Metal
c: Metal
d: Non-metal
e: Non-metal
f: Metal
g: Non-metal

Now Part 2: Fill in the blanks using words from the box:
Words: strong, sonorous, conductor, heat, ductile/flexible

Let’s match each use with the correct property:

1. *Aluminium is used for cooking pots as it is a good: ___ of ___*
→ Cooking pots need to transfer heat well → aluminium is a good conductor of heat.

2. *Iron is used for bridges as it is: ___*
→ Bridges need strong material to hold weight → iron (and steel) is strong.

3. *Silver is used for mirrors as it is: ___*
→ Mirrors rely on reflectivity/shininess — but among the given words, none say “shiny” or “reflective”. However, “sonorous” means produces sound — not relevant. “Conductor” — yes, silver is the best electrical conductor, but mirrors use its reflectivity, not conductivity. Hmm — but maybe the expected answer is based on common textbook phrasing. Wait — let’s reconsider: In many school worksheets, silver is noted for being shiny (lustrous), but “shiny” isn’t in the word bank. The word bank is: strong, sonorous, conductor, heat, ductile/flexible.

None directly mean “shiny”, but sometimes “sonorous” is misapplied — no, sonorous = produces ringing sound (like metals when struck). That’s not for mirrors.

Wait — perhaps the question expects:
Silver is used for mirrors as it is a good conductor — but that’s not why mirrors use silver. Actually, historically, silvering uses silver because of its high reflectivity, which is related to its metallic luster — but again, not in word list.

Let’s look at the fourth item:

4. *Silver is bent to make jewellery as it is: ___*
→ Bending implies it’s ductile/flexible.

So for #3 (mirrors), the only remaining plausible word is sonorous? No — that doesn’t fit.

Hold on — maybe we misread the first blank structure.

Look again:

“Aluminium is used for cooking pots as it is a good:
c ________ of ________”

The “c” likely hints at the word starting with c → “conductor” fits. Then second blank: “heat”.

Yes.

“Iron is used for bridges as it is: ________” → strongest choice: strong

“Silver is used for mirrors as it is: ________” — what property makes it suitable for mirrors? Reflectivity — but not in list. However, in some curricula, they associate “shiny” with “lustrous”, and sometimes mistakenly link to “sonorous”, but that’s incorrect.

Wait — check the word list again:
strong, sonorous, conductor, heat, ductile/flexible

Note: “heat” is a noun, others are adjectives (except “conductor” is noun/adjective). The blank after “as it is: ___” expects an adjective.

- strong ✔
- sonorous ✔ (adjective)
- conductor ✘ (noun — but can be used as noun phrase “a good conductor”)
- heat ✘ (noun, not describing silver directly)
- ductile/flexible ✔

For mirrors: silver is highly reflective, but since that’s not an option, perhaps the worksheet expects sonorous? No — that’s wrong.

Alternative idea: Maybe the mirror question is about *electrical* use? No, mirrors are optical.

Let me double-check typical school answers for such worksheets.

Upon recalling standard UK/IGCSE-style worksheets:
- Aluminium for pots → good conductor of heat
- Iron for bridges → strong
- Silver for mirrors → shiny (but not in box) — however, sometimes they accept “lustrous”, but not here.

Wait — could the word “conductor” be reused? Like “silver is used for mirrors as it is a good conductor” — still doesn’t make sense.

Let’s read the instruction again:
“Complete the word that describes the property of the material being used, and which is important for the use shown.”

For mirrors, the key property is reflectivity, which stems from its metallic luster — and luster is closely related to being a metal, but not in word bank.

Hold on — maybe there’s a typo, and one of the words is meant to be “lustrous”, but it's written as something else? No — we must work with given words.

Let’s try assigning uniquely:

Available words: strong, sonorous, conductor, heat, ductile/flexible
We have 4 blanks:

1. c ______ of ______ → clearly “conductor” and “heat”
2. iron for bridges → “strong”
3. silver for mirrors → ???
4. silver bent for jewellery → “ductile/flexible”

That leaves “sonorous” unused. But all words should be used? Not necessarily — instruction says “complete the word” from the box — may not use all.

In many similar worksheets, the mirror answer is “shiny", but since it’s not an option, and “sonorous” is the only adjective left, maybe it's a trick? No — sonorous is about sound, not reflection.

Let me search my knowledge: Is silver described as sonorous? Yes, metals are sonorous, including silver — but that’s not why it’s used in mirrors.

However, considering this is a basic worksheet, and the only adjective left after assigning strong, ductile/flexible, and using conductor+heat, the remaining word is sonorous — and perhaps the worksheet incorrectly pairs it, or expects students to know metals are sonorous, and silver is a metal — but that’s weak.

Wait — another possibility: The blank for mirrors might be just one word: “conductor” — but again, not accurate.

Let me count blanks:

- First: two blanks (c ____ of ____) → 2 words
- Second: one blank
- Third: one blank
- Fourth: one blank
Total: 5 blanks.

Word bank has 5 words: strong, sonorous, conductor, heat, ductile/flexible.

Perfect — 5 blanks, 5 words.

So assignment must be bijective:

1. c ______ of ______ → starts with c → conductor and heat
2. iron for bridges → strong
3. silver for mirrors → must be sonorous? But why?
4. silver bent for jewellery → ductile/flexible

That uses all 5.

Even if “sonorous” is not the best real-world reason, in many school-level worksheets, they do pair “silver is sonorous” as a metal property, and since other slots are taken, this is likely what’s expected.

Alternatively, could “sonorous” go to iron bridges? No, bridges don’t need to ring.

I think, for the purpose of this worksheet, the intended answers are:

- conductor, heat
- strong
- sonorous
- ductile/flexible

Yes, this matches number of blanks and word bank. It’s a simplification for young students.

So final answers:

Part 1:
a: Metal
b: Metal
c: Metal
d: Non-metal
e: Non-metal
f: Metal
g: Non-metal

Part 2:
- conductor, heat
- strong
- sonorous
- ductile/flexible

Final Answer:
1a: Metal
1b: Metal
1c: Metal
1d: Non-metal
1e: Non-metal
1f: Metal
1g: Non-metal
2: conductor, heat; strong; sonorous; ductile/flexible
