-Tensile strength (good in longitudinal direction and poor in the transverse direction)
-Compressive strength (it is better in the transverse direction that in the longitudinal direction)
-Flexural strength (it is good in the tranverse direction)
-Hardness (this can vary a lot)
-Toughness (wood is tough)
-Thermal and electrical conductivity (it is very low)
-Sound conductivity (good. Its is used to make certain musical instruments)
-Colour (different woods of different colours)
-Density (wood is a light material)]]> 2018-11-28 12:43:40 UTC https://padlet.com/LauraMorenoANDLauraRaczka/ALauraMorenoANDLauraRaczka/wish/308733886 Wood products: LauraMorenoANDLauraRaczka https://padlet.com/LauraMorenoANDLauraRaczka/ALauraMorenoANDLauraRaczka/wish/308739604 Man-made wood: enhances the properties of natural wood and reduces its price.
       -PLYWOOD: is from by an odd number of thin wood layers.
       -CHIPBOARD: is obtained from wood chips that are mixed with resin and then pressed
Wood derivatives: are usually obtained from leftover wood.
       -PAPER: is obtained by forming a paste out of wood and plant fibres.
       -CARDBOARD: is made by compressing several layers while it is wet.
       -CORK: is  obtained from the bark of the cork oak. It is waterproof lightweight and a good
insulator. ]]> 2018-11-28 12:59:31 UTC https://padlet.com/LauraMorenoANDLauraRaczka/ALauraMorenoANDLauraRaczka/wish/308739604 Metals: LauraMorenoANDLauraRaczka https://padlet.com/LauraMorenoANDLauraRaczka/ALauraMorenoANDLauraRaczka/wish/308745896 The most popular metal is iron. Metals that contain mainly iron are called ferrous metals. Metals that don´t contain iron ae called non-ferrous metals. 
FERROUS METALS: depending on the percentage of carbon in the alloyd. Can be classified as: iron, steel and cast iron.
       -Iron: When the percentage of carbon is less than 0.1% we called it iron.
       -Steel: it is mainly made of iron (0.1%) and carbon (2%).
       -Cast iron: it is made of iron (2%) and carbon (6.67%).
NON-FERROUS METALS: metals that don´t contain iron in their composition.
        -Copper: bright, red-colour metal that has been used since ancient times.
        -Tin: a silver-colour, shiny metal; it is resistant.
       -Aluminium: white, shiny, cheap and easy to recycle.
      -Zinc: bluish-white in colour and is one of the least common metals]]> 2018-11-28 13:15:07 UTC https://padlet.com/LauraMorenoANDLauraRaczka/ALauraMorenoANDLauraRaczka/wish/308745896
