🔬 Part 1: Particle Arrangement and Motion

1. Match each state of matter to its particle arrangement:

Solid:

Particles close together, vibrating in place

Liquid:

Particles far apart, moving freely and quickly

Gas:

Particles close together, sliding past each other

2. Which state of matter is most compressible (can be squashed the most)?

Solid

Liquid

Gas

3. Complete the particle properties table:

Solid particles: Arrangement: _____________ Motion: _____________

Liquid particles: Arrangement: _____________ Motion: _____________

Gas particles: Arrangement: _____________ Motion: _____________

4. Explain why air can be compressed more easily than water using particle theory:

📊 Part 2: Fair Testing and Data

5. In our syringe compression experiment, identify the variables:

Variable we changed: _________________________________

Variable we measured: _________________________________

Variables we kept the same: _________________________________

6. Why is it important to do 3 trials instead of just 1?

To make the experiment longer

To check our results are reliable and accurate

To use more equipment

7. Record your compression results:

8. Based on your data, write one evidence statement about particle compression:

In our trials, ________________________________________________

because particles in gases _________________________________

🎯 Part 3: Model Evaluation

9. How well did your particle model match your experimental results?

Perfect match - our model explained everything

Good match - mostly correct with minor improvements needed

Poor match - major changes needed to our model

10. What would you change about your particle model based on your evidence?

11. Draw and label a simple particle diagram showing why gases are more compressible than liquids:
