*We prepare or refine raw materials to obtain natural materials .
*When we process raw materials, they become processed materials (also called manufactured material).
*Any materials used to construct an object is called a technicall material.

EXERCISE 5 :
·Shoe --> Is make of leather and plastic
·Partition wall --> Is make of bricks and wood
·Streetlight --> Is make of metal, plastic and glass
·Stay cables --> Is make of steel

EXERCISE 6 :
 
·Umbrella : Is made of plastic because is water proof.
· A chair : Is make of wood or metal because persons use to sit in it so the chair have to be tough
· A frying pan : Is made of metal and some plastic, because it have to be exposed to very high temperratures, so it should be made of metal; and the handle of the frying pan is made up of plastic because, like this, is more comfortable to cook.

·Thermal Properties: They are very good conductors of heat, they expand and contract and some of them can be soldered to other metals.
·Electrical and Magnetic Properties: They are good conductors and some have a magnetic behaviour.
·Other Properties: Many rust easily, are sound conductors, are solid at room pemperature, are heavy and dense etc...]]> 2018-02-27 17:48:53 UTC https://padlet.com/belvissilvia/1FSilviaBelvisPaulaMarchante/wish/236036033 Pag. 81. technology_paula https://padlet.com/belvissilvia/1FSilviaBelvisPaulaMarchante/wish/236049107 Exercise 12.

SARDINE TIN: We will use tin

WIRES FOR AN ELECTRICAL CIRCUIT: We will use copper. ]]> 2018-02-27 18:16:18 UTC https://padlet.com/belvissilvia/1FSilviaBelvisPaulaMarchante/wish/236054561 RED BOXES. technology_paula https://padlet.com/belvissilvia/1FSilviaBelvisPaulaMarchante/wish/236059097 ·Depending on the percentage of carbon in the alloy, ferrous materials an be classified as: iron, steel and cast iron.
·When the percentage of carbon in the alloy is less than 0.1%. we call this meterial iron.
·Steel is a ferrous material made mainly from iron with 0.1% to 2% carbon.
·Cast iron is made from iron and 2% to 6.67% carbon.]]> 2018-02-27 18:22:39 UTC https://padlet.com/belvissilvia/1FSilviaBelvisPaulaMarchante/wish/236059097 METALS. technology_paula https://padlet.com/belvissilvia/1FSilviaBelvisPaulaMarchante/wish/236065451 2018-02-27 18:30:51 UTC https://padlet.com/belvissilvia/1FSilviaBelvisPaulaMarchante/wish/236065451 METALS. technology_paula https://padlet.com/belvissilvia/1FSilviaBelvisPaulaMarchante/wish/236067036 2018-02-27 18:32:49 UTC https://padlet.com/belvissilvia/1FSilviaBelvisPaulaMarchante/wish/236067036 METALS. technology_paula https://padlet.com/belvissilvia/1FSilviaBelvisPaulaMarchante/wish/236067395 2018-02-27 18:33:15 UTC https://padlet.com/belvissilvia/1FSilviaBelvisPaulaMarchante/wish/236067395
