📓 Matter: Properties of solids, liquids, and gases

Properties of Solids
1. Shape: Solids have a fixed shape.
2. Volume: Solids have a fixed volume.
3. Density: Solids have a fixed density.
4. Rigidity: Solids are rigid and maintain their shape.

Properties of Liquids
1. Shape: Liquids take the shape of their container.
2. Volume: Liquids have a fixed volume.
3. Density: Liquids have a fixed density.
4. Fluidity: Liquids can flow and change shape.

Properties of Gases
1. Shape: Gases have no fixed shape.
2. Volume: Gases have no fixed volume.
3. Density: Gases have a low density.
4. Compressibility: Gases can be compressed.

Changes in State of Matter
1. Melting: Solids change to liquids when heated.
2. Freezing: Liquids change to solids when cooled.
3. Evaporation: Liquids change to gases when heated.
4. Condensation: Gases change to liquids when cooled.

Examples and Applications
1. Solid: A book, a chair, a rock
2. Liquid: Water, oil, juice
3. Gas: Air, oxygen, helium

Fun Activities
1. Sorting Game: Sort objects into solids, liquids, and gases.
2. State of Matter Experiment: Observe changes in state of matter using ice, water, and steam.
3. Density Column: Create a density column using different liquids.
