are materials taken directly from nature that we process into other materials to make products with .
NATURAL MATERIALS 
we prepare or refine raw materials to obtain natural materials 
PROCESSED MATERIALS :
 when we processed war materials , they become processed materials , ( also called manufactured materials)
TECHNICAL MATERIALS :
any materials use to contract an object is called a technical materials                    ]]> 2017-12-12 10:56:40 UTC https://padlet.com/albalaurapaula/slbx1b6r9k2x/wish/215350569 albalaurapaula https://padlet.com/albalaurapaula/slbx1b6r9k2x/wish/216869825 EX 5 PAGE 77 :

Each materials has certain characteristics or properties that make it suited to a certain use 

When we choose materials we can consier different criters : 
. will be strong enough for that obejct 
. weighs as litlle as possible 
.makes the product looks atractive 
.feels nice to touch 
. is as cheep as possible 
.we can bouild whit asn is avilable an affordable
.is ready available 
.is not troxic o contaminated
