  1. Materials Scientists Making the right choices

  2. How do we decide what material to use for what job? • How do the properties of a material determine its’ use?

  3. Lets start withlooking at why we don’t choose certain materials

  4. Why would we not make… • a rubber bridge • chocolate teapot • a lead parachute • a wooden light-bulb • a glass tyre • a concrete lifebelt Try to use the following words in your explanation: FlexibleConductor BrittleMelting point Density These are physical properties of materials

  5. What would we use to make • a bridge • teapot • a parachute • a light-bulb • a tyre • a lifebelt Try to use the following words in your explanation: FlexibleConductor BrittleMelting point Density

  6. Material Properties • Strength • How much force is needed to break it • Hardness • How difficult it is to scratch • Conductivity (heat and/or electricity) • How well it lets the energy flow through it • Stiffness • How flexible it is • Melting point • The temperature at which it turns from solid to liquid • Density • How much mass it has for a given size

  7. Some of these materials occur naturally • An increasing number are man-made (synthetic) Natural Synthetic

  8. Draw a car and labelwith the material used foreach part and why
