🔬 Part 1: Understanding Particle Theory

1. The particle theory of matter has three main points. Circle the correct statements:

All matter is made up of tiny particles

Particles are always moving

Particles only exist in solids

Particle behaviour changes in different states

2. Which state of matter has particles that are closely packed and only vibrate?

Solid

Liquid

Gas

3. In which state do particles move freely but stay close together?

Solid

Liquid

Gas

4. What happens to particle movement when matter is heated?

Particles move faster

Particles move slower

Particles stop moving

✏️ Part 2: Particle Behaviour

5. Complete the sentences about particle arrangement:

In a solid, particles are _____________ packed and can only _____________.

In a liquid, particles can _____________ around each other but stay _____________.

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

6. Explain why ice (solid water) has a fixed shape but water (liquid) takes the shape of its container:

7. Using the particle theory, explain what happens when you heat a liquid until it becomes a gas:

🎨 Part 3: Drawing Particles

8. Draw how particles are arranged in each state of matter. Use circles to represent particles:

SOLID

LIQUID

GAS

9. Think about today's lesson. Write one new thing you learned about particles:
