Materials & their properties
- Materials have different properties e.g. strong, hard, rough etc.
- Some materials are magnetic but most are not.
- All materials can be sorted into natural, e.g. sand, or man-made, e.g. plastic.
- Water turns to steam when heated but on cooling returns to water.
- Materials change when they are cooled e.g. water becomes ice.
- Mains electricity is dangerous.
- A battery needs to be connected by both the positive and negative pole before electricity will flow.
- You need a complete circuit with a battery for electricity to flow.
- Some metals are magnetic e.g. steel.
- Light comes from a source and there are many different sources e.g. sun, torch etc.
- Shiny objects can only reflect light and therefore do not shine in the dark.
- Light helps us to see.
