📚 Part 1: Multiple Choice & Classification

1. What is matter?

Energy only (no mass)

Something that has mass and takes up space

Light and sound only

Temperature measured in °C

2. Which property best describes a liquid?

Keeps a fixed shape

Holds a fixed volume and can flow to take the shape of its container

Particles are far apart and move freely

Cannot be poured

3. Which state of matter is easy to compress?

Solid

Liquid

Gas

None of the above

4. Check all that are solids:

Ice

Water

Air

Cloth

Sand

Oil

✏️ Part 2: Short Answers & Modelling

5. In one sentence, explain the particle model for solids, liquids and gases.

6. Draw simple particle diagrams for each state. Label each drawing: Solid, Liquid, Gas.

7. Why does a gas have no fixed shape? Write 1–2 sentences.

8. Group sorting reflection: List two observable features you used to decide if an object was a solid or a liquid (e.g., keeps shape, pours).

🌱 Extension & Support

Extension challenge (advanced learners):

Find one traditional First Nations Australian use of a natural material (e.g., resin, plant oil, bark). Describe which state(s) of matter the material is used in and why that property makes it useful.

Differentiation & dyslexia-friendly options (teacher notes for classroom use):

For diverse learners: Give hands-on samples (ice, water, inflated balloon) and let students sort physically. Allow verbal or pictorial responses rather than written answers if needed.

Extension: Ask advanced students to explain how particle motion changes when ice melts at 0°C or when a gas is compressed.

Dyslexia-friendly reading option: Provide a coloured strip or ruler to follow lines of text, use short sentences, and pair text with clear images or diagrams. Offer audio of the worksheet prompts where possible.
