Water, an extraordinary substance ...

       Water is one of the most extraordinary substance existing, thanks to her there is life on the planet. It is the only substance in liquid is denser than solid state and thanks to that the ice floats, allowing the existence of the iceberg and life under water when frozen seas.
I leave the link of a very good video that explains very well the physical and chemical properties of water.

The BING BANG theory...

      As many know one of the best and most complete explanations of the creation of the universe is the Big Bang theory.
I found online a very good article that explains in detail this theory, which seemed very good to me share with you because the students can go to ask it in class, especially those who are serving 3 rd.
Here I leave the link so they can read.

Also I leave the link of a video that is very good about the Big Bang theory.

Learning theory of Vygotsky

          A few classes ago, we talked about learning theory of Vygotsky, the psychology of this study the activity of the subject and it does not respond to specific stimuli, but uses its transforming activity. To get to the modification of the subject uses stimuli mediating instruments. It is culture that provides the tools necessary to modify the environment, also to be culture consisting mainly of signs or symbols, they act as mediators of the actions.

       For Vygotsky, the social influences on learning rather than the attitudes and beliefs have a profound influence on how you think and what you think. The context is part of the development process and, as such, shape cognitive processes, the social context must be considered at several levels:
A. - The immediate interactive level, consisting of the (those) individuals who (is) the child interacts at the time.
2.-The structural level, constituted by the social structures that influence the child, such as family and school.
3. - The cultural and general social level, constituted by the society at large, such as language, number system


       The influence of context in the development of the child, for example, a child growing up in a rural environment where relationships are specified only to family ties will have a different development to that which is surrounded by cultural environments more conducive . The rural child develop faster your body control and knowledge of the field, the urban environment will have closer cultural and technological aspects.

       To Vygotsky development and personality formation occurs in the very process of teaching and learning.

                         

                                       

I think they're funny...

I would like to share with you two pictures that I find very funny:                                

 ...a great time when Kekule discovered the benzene form, although I don't think it was in the way shown in the picture, jajajaja.

ok, maybe when we graduate we still thinking this!!!!!!!!

Incredible...

       Today, we had a test in biochemestry, and one of the topics was about the DNA, so I started thinking about the surpraisin of this.

     I do not know about you but I think it's really amazing how the man could get to discover something like that.
The composition of the structure of DNA was discovered in 1953 by two biologists. They know of the existence of nucleic acid and composed, they prepared an article in which they had come to count as the structure of DNA.
I read about this experiment and really surpriced me because it is amazing in which they lived in these Biolos arrived to discover the genetic code.

I was sare with you a link where you can read part of the article published by Watson and Crick (the  scientists who discovered the structure of DNA).

Enjoy it...
