Metals

                                                            METALS

Is a hard element that shines that can be in a rock or in the soil like iron, gold.Metals can be good conductors of electricity.

TYPES OF FERRROUS: 

FERROUS METALS:
  Carbon steel: iron content 98.6 to 99.4 %. It is used to make cutting tools such as drill bits.





  




 Stainless steel: is made of iron, chromium and nickel. It resists corrosion and staining and is used   for the likes of cutlery and surgical instrumentation.

 



    






Cast iron: It is iron about  94 to 98%. Is very strong but is brittle. It's used for manufactured items such as engine blocks and manhole covers.

 






NON-FERROUS METALS:  

   Aluminium: very lightweight and easily worked. Used in aircraft manufacture, window frames and some kitchen ware.

    Cooper: is a natural ocurring substance, it conducts heat and electricity, it's used for wiring, tubing and pipe work.

 






    Brass: is a combination of cooper and zinc. Is usef for ornamental purposes and within electrical fittings.


 







     Silver: mainly a natural substance, but mixing with cooper creates sterling silver. It's used  for decorative impact in jewellery and ornaments, and also to solder different metals together.

 







    


 Lead: is a naturally occurring substance. It's heavy and very soft, is often used in roofing, in batteries and to make pipes.

TYPES OF FERROU ALOYS:

- Cast iron: are usually manufactured through casting technique owing to their brittle nature due to presence of iron carbide.

TYPES OF NON-FERROU ALOYS: 

Cooper aloys: are excellent electrical conductors and very good thermal conductivity and can be easily machined and soldered.
Brass: cooper and zync atoms are randomly dispersed at lattice points. 
Bronzes: are softer and weaker than steel. corrosion resistance, heat and electric conductivity are also better than steel, while the cost is higher than steels.

SUPERCONDUCTOR METALS: 

Mercury, lead, tin, aluminium and zinc.

MY PERSONAL OPINION

                                       MYRA'S ADVENTURE
 
I like so much to make the movie but I think we start to record it so late and we don't have in off time to film with more details the movie.
For next year I hope that everyone makes a good film and then saw it during the second break.
In the group we had worked well but we had some problems to film because the camera didn't work and we need to film with the phone but, in general I like so much to make the movie.

STRUCTURES

STRUCTURES

DEFINITION: object made of a particular shape who is made in order to protect another thing, support something, to help people, etc.

NATURAL STRUCTURES: are structures made by the nature with natural things, structures that are not made by humans.

EXAMPLES:

Jeju island:                                      Iguazu falls:                      Mount Everest:

MAN-MADE STRUCTURES: are structures made by humans and can have a profit or just to make something beatiful.

EXAMPLES:

Eiffel Tower:                                                              Big Ben:    
                  
                          

AN AMAZING STRUCTURE !:

Burj Khalifa:

Types of forces:

FORCE: a force is to make some effort to an object.

Contact Forces: 

-Tension Force
-Friction Force
-Normal Force
-Air Resistance Force
-Applied Force
-Spring Force  

Distant Forces: 

-Electrical Force
-Gravitational Force
-Magnetic Force

Hour of code

MATEU JOAN LLINÀS MOREY         2C        TECHNOLOGY

HOUR OF CODE

Program is so important nowadays because everything is related with technology and program helps us in our daily life. We have social networks that helps to meet people and know abou things that you didn't know. For me program is important because every day I program things with the computer, the cell phone, etc.

For me scratch was a good experience coding because I learn to create a situation in a place with the custome that I want that makes the things that I want, it was so nice. Now I know how to create a nicde scratch.

I thing that one day a year in school the teachers can let us to use the mobile phone during an hour, because this was a thing that everyone wants, including me.

What is technology

                                       WHAT IS TECHNOLOGY?

Technology is the collection of techniques, skills, methods and processes used in the production of  services. 
Every day I use a lot of technological things like for example: cell phone, digital alarm, TV, table, bed,etc.

Cell phone: it's helpful for a lot of things, you can comunicate with people of every part of the world. It haves the possibility to have internet. it's possible to make a lot of more things are not so important.

 Digital alarm: it's programmed at the hour that you put and when it's the hour rings a bell that wokes you up.

  The TV is a system that shows a lot of  channels about different topics











     The table is a rectangular piece of wood that helps you for a lot of things: to eat,to make homework, etc.
 
 The table is a piece of furniture wich is uded as a place to sleep or relax.






     

                    
The knowledge in technology is very important because you have to know everything about what you are crafting. Technology can be the knowledge of techniques. The materials are so important for the craft section, the materials are the important part of the sructure.

 Hello, I'm Mateu Joan, I'm 13 years old and I live in Sant Llorenç des Cardessar.
 I like to play football and I am in a football team "Carde", i love animals but I didn't have anyone. I have a sister that is 6 and loves music.I didn't know really what I want to be when I grew up, I only know that I want to be more or less like bussines man. I like technology classes because I like computers, mobile phones, etc. For me the best technological object is the mobile phone because has internet, a lot of games and a lot of tools to work, is like a computer but with the advantage to move with them.
