Physical properties of materials and their uses
CopperPlasticdiamondAluminiumsteel What are the properties of each material? What are these things used for? How are the uses related to the properties?
Carry out an investigation to compare the properties of some of these materials. Thermal conductivity is easy to compare

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
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.
