Lesson Details
Key learning points
- A substance may have a solid, liquid and gas state
- In the solid state a substance has a fixed shape, it does not flow and cannot be compressed
- In the liquid state a substance can flow, it fills the shape of its container and cannot be compressed
- All substances are made of particles that are too small to see
Common misconception
Students think that the particles are embedded in the substance
Ensure that students are reminded that all matter is made of small particles and nothing is between the particles.
Keywords
Solid state - the substance has a fixed shape and cannot be compressed
Liquid state - the substance can flow, it fills the shape of its container and cannot be compressed
Gas state - the substance does not have a fixed shape and will take the shape of its container
Flow - when a substance can be poured from one place to another
Compress - when a substance is made to take up less space (volume)
