Completed Answers:
All materials are either solid,
liquid or gas.
A brick, chocolate and glass are all
solids.
Solids can be
held. They have a definite
shape.
The molecules that make up a solid are packed
tightly together.
Water, milk and syrup are all
liquids. Liquids can be
poured and take the shape of the
container they are in.
Steam, helium and carbon dioxide are all
gases. Gases are mostly
invisible. They will fill empty
spaces.
Steam is a
gas, water is a
liquid and ice is a
solid.

## 🔍 Explanation:
This worksheet teaches the
three states of matter:
solid,
liquid, and
gas.
1. All materials are either solid, _liquid_ or gas.
→ This is the basic classification of matter. Every substance exists in one of these three states under normal Earth conditions.
2. A brick, chocolate and glass are all _solids_.
→ These are everyday examples of solids — they keep their shape and don’t flow.
3. Solids can be _held_. They have a definite _shape_.
→ Solids are rigid and can be picked up or held. Unlike liquids or gases, they don’t change shape unless acted upon.
4. The molecules that make up a solid are packed _tightly_ together.
→ In solids, particles are very close together and vibrate in place — this gives them fixed shape and volume.
5. Water, milk and syrup are all _liquids_.
→ These are common liquids — they flow and take the shape of their container.
6. Liquids can be _poured_ and take the shape of the _container_ they are in.
→ Liquids flow easily and conform to the shape of whatever holds them — but they still have a fixed volume.
7. Steam, helium and carbon dioxide are all _gases_.
→ Steam is water vapor (gas), helium is a noble gas, and CO₂ is a gas at room temperature.
8. Gases are mostly _invisible_. They will fill empty _spaces_.
→ Most gases cannot be seen (like air or steam). They expand to fill any available space — they have no fixed shape or volume.
9. Steam is a _gas_, water is a _liquid_ and ice is a _solid_.
→ This shows how the
same substance (water) can exist in all three states depending on temperature:
- Ice = solid (frozen)
- Water = liquid (room temp)
- Steam = gas (boiled)

Key Science Concept:
Matter changes state based on
temperature and pressure. The arrangement and movement of
molecules determine whether something is a solid, liquid, or gas.
