Apple

The important thing about an apple is that it is round.

It is red.

You bite it, and it is white inside,

And the juice splashes in your face,

And it tastes like an apple,

And it falls off a tree…..

But the important thing about an apple is that it is round

Aluminium

Aluminium is the most abundant metal in theearth´s surface, and, after steel is the mostwidely used. It has a good resistance tocorrosion because forms a natural surfaceoxide film which keeps the material. It is agood conductor of both electricity and heat. Itis quite light in weight which gives its alloys aninteresting low density. Products made ofaluminium are window frames, cookingsheets, drink can, power cables…

Aluminium

The important thing about

aluminium is that it is a

good conductor of both heat and

electricity

It’s the most abundant metal in

earth’s surface

It is widely used

It is not easily rusted

It isn’t heavy

It is light

And it is used to make window

frames, cans or power cables.

But the important thing about

aluminiumIs that it is a good conductor of

both heat and electricity

Plywood

• Plywood is made up of three or more thinlayers (veneers) of wood, glued together. Theyare placed so that the grains run in alternatedirections. This process gives the materialuniform strength. Examples of products madeof plywood are school chairs and desks, tabletennis racket…

Plywood

The important thing about plywoodis that it is uniformly strongIt has layers glued togetherThe layers have the grains running indifferent directionsPeople make chairs and decks for schoolYou can make a table tennis racket too

And it is a manufactured board .............

But the important thing about plywoodIs that it is uniformly strong

The important thing about beech

wood is that it is very tough and

quite hard.

It is a very light brown wood with

characteristics speckles.

It has no taste or odour,

which make it suitable for children

toys and kitchen utensils.

But the important thing about beech

wood is that it is very tough and

quite hard.

The important thing about

copper is that it is a good

conductor of electricity and heat.

It is the third most important

metal

You can make glue gun bits, wires

and radiators.

But the important thing about copperis that it is a good conductor of

electricity and heat.

The important thing about

grey cast is that it is very

brittle.

It is very good under compression

forces.

It isn't very good under tension

forces.

You can make blocks of engines,

bases of pillar drill... with it.

And it is an alloy which contains

3% carbon.

But the important thing about

grey cast is that it is very brittle.

The important thing about pine

wood is that it can be easily

worked, when it is dry.

You can make floorboards,

gates, window frames and more

things with it.

It is almost knot free.

And it isn't a manufactured board

it is a natural wood.

But the important thing about pine

wood is that it can be easily

worked, when it is dry.

The important thing about copper is

that it is a good electrical conductor

It protects itself from corrosion with a

natural oxide film

You can make the glue gun bit, wires,

radiator core... with it.

It isn't a thermal insulator

And it is the third most important metal

But the important thing about copper is that

it is a good electrical conductor

The important thing about mild steel is

that it is harder, tougher and has a higher tensile strength than iron.

It has a very low amount of carbon (0.1-0.3%)

It is used in many applications because of its properties: screws nails, structural shapes...

But the important thing about mild steel is that it is harder, tougher and has a higher tensile strength than iron.

The important thing about plywood is that the grains run in alternate directions and it gives the material uniform strength.It is an example of Manufactured boards.You can make with it chairs, desks, table tennis racked...

It is made up of three or more thin layers ofwood, glued together.

But the important thing about plywood isthat the grains run in alternate directionsand it gives the material uniform strength.

The important thing about high carbon steel is that it is very hard and brittle

It is used in cutting tools and products.

It has high carbon amount (0,7-1,3 %)

But the important thing about

high carbon steel is that it is very hard and brittle
