Worksheet activity identifying solids, liquids, and gases by selecting the odd one out in each row.

The task asks you to look at each row of pictures and find the one that does not belong — meaning it is the odd one out based on whether it is a solid, liquid, or gas.

Let’s go row by row:

Row 1:
- Coffee cup (steam rising) → gas (steam)
- Balloon → gas (inside)
- Pencil → solid
- Person coughing → gas (germs or air particles)

Wait — actually, let’s think again. The balloon contains gas, the steam is gas, the cough releases gas/particles, but the pencil is clearly a solid. So the pencil is the odd one out? But wait — maybe we’re supposed to group by state of matter per row.

Actually, looking closer: In Row 1, three items are associated with gases (steam, balloon, cough), and one is a solid (pencil). So pencil doesn’t belong.

But hold on — maybe the instruction means: In each row, three things are the same state (solid, liquid, or gas), and one is different. Let’s check each row carefully.

---

Row 1:
- Steam from coffee → gas
- Balloon → contains gas
- Pencil → solid
- Coughing person → releasing gas/air

→ Three gases, one solid → Pencil is the odd one.

---

Row 2:
- Glass of water → liquid
- Pond → liquid
- Milk carton pouring → liquid
- Bicycle wheel → solid

→ Three liquids, one solid → Bicycle wheel is the odd one.

---

Row 3:
- Rain cloud → water droplets (liquid) falling
- Flower → solid
- TV → solid
- Hot dog → solid

Wait — rain is liquid, but flower, TV, hot dog are solids. That would mean rain is the odd one? But that seems off.

Actually, let’s reconsider: Maybe “rain” here represents water in liquid form, while the others are solids. So yes — rain (liquid) vs. flower, TV, hot dog (solids). So rain cloud is the odd one? But that feels strange because rain is still water.

Alternatively — perhaps the question is about what is NOT a solid? No, the instruction says “draw an X on the picture that does not belong” — implying in each row, three are alike, one is different.

In Row 3:
- Rain → liquid
- Flower → solid
- TV → solid
- Hot dog → solid

So rain is the only liquid → rain cloud is the odd one.

But wait — maybe I’m misinterpreting. Let’s look at Row 4.

---

Row 4:
- Maple syrup bottle → liquid
- Perfume spray → liquid (in bottle) and gas (spray)
- Paint can pouring → liquid
- Bucket pouring paint → liquid

All seem to be liquids. But perfume spray might be considered gas when sprayed? Hmm.

Actually, all four are primarily liquids:
- Maple syrup = liquid
- Perfume = liquid (even if sprayed, it’s a liquid mist)
- Paint can = liquid
- Bucket pouring paint = liquid

So maybe no odd one? But that can’t be.

Wait — perhaps the perfume spray is meant to represent gas? Because it’s a spray can — aerosol. So maybe:

- Maple syrup → liquid
- Perfume spray → gas (aerosol)
- Paint can → liquid
- Bucket pouring → liquid

Then perfume spray would be the odd one (gas among liquids).

That makes sense.

Row 5:
- Ice cream cone → solid (ice cream is frozen solid)
- Glass with bubbles → liquid (soda)
- Sun melting puddle → liquid (puddle) and gas (evaporation?) — but the puddle is liquid
- Person breathing → gas (air)

Wait — ice cream is solid, soda is liquid, puddle is liquid, breathing is gas.

So we have: solid, liquid, liquid, gas → two liquids, one solid, one gas. Not clear.

Perhaps the ice cream is melting — so it’s becoming liquid? But it’s still mostly solid.

Alternatively — maybe the sun is not a state of matter? But the sun is shown melting the puddle — so the puddle is liquid.

This is tricky.

Let’s list them:

- Ice cream → solid
- Soda glass → liquid
- Puddle under sun → liquid
- Person breathing → gas

So three states represented? But we need three alike, one different.

Unless... the ice cream is the only solid? Then it’s the odd one.

But soda and puddle are both liquids, breathing is gas — so no majority.

Wait — perhaps the “sun” is not part of the state — the puddle is the focus. So:

- Ice cream → solid
- Soda → liquid
- Puddle → liquid
- Breathing → gas

Still not three alike.

Maybe I made a mistake earlier.

Let me try a different approach. Perhaps in each row, three items are examples of ONE state of matter, and one is another.

Let’s re-express each item by its primary state:

Row 1:
- Steam → gas
- Balloon → gas (filled with)
- Pencil → solid
- Cough → gas (particles/air)

→ 3 gases, 1 solid → Pencil is odd.

Row 2:
- Water in glass → liquid
- Pond → liquid
- Milk pouring → liquid
- Bicycle wheel → solid

→ 3 liquids, 1 solid → Bicycle wheel is odd.

Row 3:
- Rain → liquid
- Flower → solid
- TV → solid
- Hot dog → solid

→ 3 solids, 1 liquid → Rain cloud is odd.

Row 4:
- Maple syrup → liquid
- Perfume spray → this is tricky. If it’s the spray coming out, it’s aerosol (gas + liquid droplets), but often classified as gas in such contexts. Or if it’s the bottle, it’s liquid. Looking at the image — it shows the spray can with spray coming out, so likely representing gas/aerosol.
- Paint can pouring → liquid
- Bucket pouring → liquid

Assuming perfume spray is gas → then 3 liquids, 1 gas → Perfume spray is odd.

If perfume spray is considered liquid, then all are liquids — but that can’t be, since the task requires one odd one out.

So likely, perfume spray is intended to be the gas.

Row 5:
- Ice cream → solid
- Soda with bubbles → liquid
- Puddle → liquid
- Person breathing → gas

Again, not three alike. Unless...

Wait — the ice cream is melting — so it’s transitioning, but still primarily solid.

Soda is liquid, puddle is liquid, breathing is gas — so two liquids, one solid, one gas.

Perhaps the breathing is the odd one? But why?

Another idea: Maybe the sun is not an object — it’s a source of heat. But the puddle is the focus.

Perhaps the ice cream is the only thing that is typically eaten as a solid, while others are not? Not helpful.

Let’s think differently. In Row 5, three items involve water in some form: ice cream (frozen water), soda (water-based), puddle (water). Breathing is air — not water.

So person breathing is the odd one.

That makes sense!

Similarly, in other rows, we can find the common theme.

But the task is about solids, liquids, gases — not about water.

Perhaps for Row 5:

- Ice cream → solid
- Soda → liquid
- Puddle → liquid
- Breathing → gas

No clear majority.

Unless the ice cream is considered to be melting, so it's not purely solid? But that's stretching.

I recall that in many such worksheets, ice cream is considered a solid, soda is liquid, puddle is liquid, and breathing is gas — so the breathing is the only gas, making it the odd one if the others are not gas.

But there are two liquids and one solid — so not three alike.

Perhaps the worksheet has a mistake, or I'm missing something.

Let's look at the last row again:

- Ice cream cone: solid
- Glass with bubbles: liquid (soda)
- Sun melting puddle: the puddle is liquid, sun is not a state
- Person breathing: gas

If we ignore the sun and focus on the puddle, then we have solid, liquid, liquid, gas.

Still not three alike.

Another possibility: the "sun" is meant to represent heat, which is energy, not matter — so it doesn't belong? But the instruction is about solids, liquids, gases — states of matter.

Perhaps in this context, the sun is not considered, and the puddle is the focus.

I think the intended answer for Row 5 is that the person breathing is the odd one because it's gas, while the others are related to water in different states: ice cream (solid water), soda (liquid water), puddle (liquid water). So breathing is not water-based.

But the topic is solids, liquids, gases — not water.

Perhaps for consistency, in each row, three are the same state, one is different.

For Row 5, if we consider:

- Ice cream: solid
- Soda: liquid
- Puddle: liquid
- Breathing: gas

Then there is no three-of-a-kind. Unless the ice cream is considered to be in the process of melting, so it's not a good example of solid.

I found a better way: let's assume that in Row 5, the ice cream is solid, the soda is liquid, the puddle is liquid, and the breathing is gas — so the breathing is the only gas, and since there are two liquids and one solid, the breathing is still the odd one because it's the only gas.

But that's not consistent with the pattern of "three alike, one different".

Perhaps the worksheet expects us to identify the one that is not a solid, or not a liquid, etc., but the instruction doesn't specify.

Let's read the instruction again: "Draw an X on the picture that does not belong."

And the title is "Solids, Liquids, And Gases", so likely, in each row, three items are examples of one state, and one is another.

For Row 5, if we take:

- Ice cream: solid
- Soda: liquid
- Puddle: liquid
- Breathing: gas

Then the only way to have three alike is if we consider the soda and puddle as liquids, and ice cream as solid, breathing as gas — no three alike.

Unless the ice cream is considered to be a liquid because it's melting? But that's not accurate.

I recall that in some curricula, ice cream is classified as a solid, even when melting.

Perhaps for Row 5, the odd one is the sun, but the sun is not a state of matter.

Looking back at the image description, in Row 5, the third item is "sun melting puddle" — so the picture shows the sun and a puddle. The sun is not a state of matter, so it might be the odd one.

But the instruction is to draw X on the picture that does not belong, and the picture includes the sun and puddle together.

This is ambiguous.

To resolve this, let's look for a standard answer or logical choice.

Another idea: in Row 5, the ice cream is solid, the soda is liquid, the puddle is liquid, and the breathing is gas — so the breathing is the only one that is not water-based, but again, not relevant.

Perhaps the intended answer is that the person breathing is the odd one because it's gas, and the others are not gas.

But let's calculate the states:

- Ice cream: solid
- Soda: liquid
- Puddle: liquid
- Breathing: gas

So two liquids, one solid, one gas. The breathing is the only gas, so it might be the odd one.

Similarly, in Row 3, rain is liquid, others are solid — so rain is odd.

In Row 4, if perfume spray is gas, then it's odd.

For Row 5, if we must choose, the breathing is the only gas, so it could be the odd one.

But let's see the first few rows are clear.

Perhaps for Row 5, the ice cream is the odd one because it's the only solid, while the others are liquids or gas.

Soda and puddle are liquids, breathing is gas — so no majority.

I think I need to make a decision.

Let me search for similar worksheets online or recall standard answers.

Upon second thought, in many such worksheets, for a row like:

- Ice cream
- Soda
- Puddle
- Breathing

The breathing is considered the odd one because it's gas, and the others are associated with water in solid or liquid form, but the topic is states of matter, so perhaps the breathing is the only gas, and since there are two liquids, it's still the odd one.

But to be consistent with the pattern, let's assume that in each row, three are the same state, one is different.

For Row 5, if we consider the ice cream as solid, soda as liquid, puddle as liquid, breathing as gas — then there is no three-of-a-kind. Unless the puddle is considered to be evaporating, so gas, but that's not indicated.

Perhaps the sun is the odd one because it's not matter.

I think the safest bet is to go with the breathing as the odd one for Row 5, as it's the only gas.

So summarizing:

Row 1: Pencil (solid among gases)
Row 2: Bicycle wheel (solid among liquids)
Row 3: Rain cloud (liquid among solids)
Row 4: Perfume spray (gas among liquids)
Row 5: Person breathing (gas among solids and liquids? But not consistent)

For Row 5, if we take the ice cream as solid, soda as liquid, puddle as liquid, breathing as gas — then the breathing is the only gas, so it's the odd one.

Yes.

So final answers:

Row 1: Pencil
Row 2: Bicycle wheel
Row 3: Rain cloud
Row 4: Perfume spray
Row 5: Person breathing

Now, to confirm, let's write it down.

Final Answer:
Row 1: Pencil
Row 2: Bicycle wheel
Row 3: Rain cloud
Row 4: Perfume spray
Row 5: Person breathing

But the task is to draw an X on the picture, so in the response, I need to specify which one in each row.

Since the user will see the image, I can describe it.

But in the final answer, I should list them.

Perhaps:
- In row 1, the pencil does not belong.
- In row 2, the bicycle wheel does not belong.
- In row 3, the rain cloud does not belong.
- In row 4, the perfume spray does not belong.
- In row 5, the person breathing does not belong.

Yes.

So for the Final Answer section, I'll write that.
