In a gas, particles move _____________ and are spread _____________ apart.

🏗️ Part 3: Material Uses and Applications

5. Match each material with its best use by drawing lines between them:

1. Glass

2. Metal

3. Fabric

4. Plastic

A. Making clothing

B. Building car frames

C. Making windows

D. Food containers

6. For the ball protection challenge, which materials would you choose and why?

Check all materials you would use:

Soft fabric (for cushioning)

Hard plastic (for structure)

Metal (for strength)

Bubble wrap (for protection)

7. Explain your material choices for the ball protection challenge:

🌏 Part 4: Real-World Connections

8. Circle the correct answer: Why do we use glass for windows instead of metal?

Glass is stronger than metal

Glass is transparent so we can see through it

Glass is cheaper than metal

Glass is lighter than metal

9. Think about how First Nations Australians used natural materials. Fill in the examples:
