1 Physical properties of materials and their uses

2 CopperPlasticdiamondAluminiumsteel What are the properties of each material? What are these things used for? How are the uses related to the properties?

3 Carry out an investigation to compare the properties of some of these materials. Thermal conductivity is easy to compare

4 Copperplasticdiamondaluminiumsteel Electrical conductivity 59.6 × 10 6 Sm -1 Very low 37.8 × 10 6 Sm -1 10.4 x 10 6 Sm -1 Thermal conductivity 400 W/(m K)0.5 W/(m K) 1800 W/(m K) 237 W/(m K)80 W/(m K) Density8920 kg m -3 920 kg/m 3 3500 kg m -3 2700 kg m -3 7874 kg m -3 Source

5 Name of material (element, mixture, or compound) Reason for choice giving material data Are there any other factors that might affect the choice of material? Cable for a ring mains at 230V or higher Making a drill bit for very hard rock Material for constructing a plane Material for making a saucepan Making a storage container Making body panels for a car

6 Plenary: Look at the answers of your partner or another group. Do you agree with their reasons? Are there any other possible materials that could be used for that purpose? Have they used valid reasons and data to support their answer? You may wish to make alterations to your own work following this discussion with your peers.
