Drag and drop the items into the correct state of matter.
| Property | Solid | Liquid | Gas |
|---|---|---|---|
| Shape | Fixed | Takes container shape | Fills container |
| Volume | Fixed | Fixed | No fixed volume |
| Compressibility | Can't be compressed | Can't be compressed | Can be compressed |
| Density | High | Moderate | Low |
| Flow | Can't flow | Flows slowly | Flows quickly |
All substances are made of particles in constant motion. The motion depends on the energy they possess.
Use your mouse or finger to draw how particles are arranged in each state.

Key terminology to remember:
Density: High, Moderate, Low. Arrangement: Regular (Solid) vs Irregular (Liquid/Gas). Behaviour: Vibrate, Slide, Move Randomly.
"Susan and Jeremy went to a concert. Initially, they were close to the stage which was packed (they only bobbed their heads). Then they moved to a spaced-out area to dance. Finally, at the end, everyone spread out in all directions."
1. At what stage were they like a Solid?
2. At what stage were they like a Liquid?
3. At what stage were they like a Gas?
Strength: It shows how density and freedom of movement change between states.
Weakness:
Suggested Answers:
Solid: Near the stage (packed, barely moving, bobbing/vibrating heads).
Liquid: Moving away to dance (spaced out enough to flow past each other).
Gas: Leaving the concert (moving randomly in all directions).
Weakness: The model fails to show the specific bonds/forces holding particles together or the fact that people have brains and choices, unlike particles.
