Let’s go step by step to solve each part of the worksheet.

Part 1: True or False

We need to decide if each statement about solids, liquids, and gases is true or false.

1. Solids can change their shape.
→ Solids keep their own shape unless you break them or force them (like clay). But normally, they don’t change shape on their own. So this is False.

2. Liquids take the shape of the container.
→ Yes! If you pour water into a cup, it becomes cup-shaped. In a bowl, it becomes bowl-shaped. So this is True.

3. Liquids keep their shape.
→ No, that’s what solids do. Liquids flow and change shape. So this is False.

4. Gases do not have a fixed shape.
→ Gases spread out to fill any space — like air in a room or balloon. They don’t hold one shape. So this is True.

5. Gases are often invisible.
→ Think of air — you can’t see it. Steam? Sometimes you see mist, but pure gas like oxygen or nitrogen is invisible. So yes, True.

✔ Answers for Part 1:
1. False
2. True
3. False
4. True
5. True

Part 2: Classify items as solid, liquid, or gas

Look at each picture and think: Does it hold its shape? Flow? Spread out?

Top row:

- Steaming coffee cup → The steam rising is gas, the coffee inside is liquid. But since the image shows steam, we’ll say gas.
- Oil being poured → That’s flowing, so liquid.
- Butter blocks → Hard, holds shape → solid.
- Raw egg (yolk + white) → Flows slightly, but mostly stays together → still considered liquid (egg white and yolk are liquids).
- Nata montada (whipped cream) → It’s fluffy but holds some shape — actually, it’s a foam (gas trapped in liquid), but for school level, usually called solid because it doesn’t flow easily. Wait — let’s think again. Whipped cream is soft and can be scooped — many teachers classify it as solid for simplicity. But technically it’s a colloid. For this level, let’s go with solid.

Bottom row:

- Tomato sauce jar → Sauce inside is liquid.
- Cartoon wind/cloud → Represents moving air → gas.
- Melted butter in dish → Liquid form → liquid.
- Ice cubes → Frozen water → solid.
- Zucchini slices → Firm vegetable → solid.

Wait — let’s double-check:

Actually, for “nata montada” — in Spanish, it means whipped cream. In science class, sometimes it’s tricky. But since it’s served in a tub and holds shape when scooped, we’ll call it solid.

But wait — another way: if it pours or flows, it’s liquid. Whipped cream doesn’t really flow — it piles up. So solid is okay.

Final classification:

Top row (left to right):
→ Gas (steam)
→ Liquid (oil)
→ Solid (butter)
→ Liquid (raw egg)
→ Solid (whipped cream)

Bottom row (left to right):
→ Liquid (tomato sauce)
→ Gas (wind cartoon)
→ Liquid (melted butter)
→ Solid (ice cubes)
→ Solid (zucchini)

✔ So list:

Gas, Liquid, Solid, Liquid, Solid,
Liquid, Gas, Liquid, Solid, Solid

Part 3: Drag and drop names of changes of matter

The diagram shows:

Solid ←(cool)← Liquid ←(cool)← Gas
and
Solid →(heat)→ Liquid →(heat)→ Gas

Arrows:

From Solid to Liquid with heat → that’s melting

From Liquid to Gas with heat → that’s evaporation

From Gas to Liquid with cool → that’s condensation

From Liquid to Solid with cool → that’s freezing

So the boxes:

Top left arrow (Solid → Liquid): melting

Top right arrow (Liquid → Gas): evaporation

Bottom right arrow (Gas → Liquid): condensation

Bottom left arrow (Liquid → Solid): freezing

✔ Fill in:

Top left box: melting
Top right box: evaporation
Bottom right box: condensation
Bottom left box: freezing
