Sólidos y Líquidos

En nuestra clase de Fisicoquímica estuvimos viendo como están compuestos los Sólidos y los Líquidos del libro. Luego nuestra profesora Susy Perez Rey nos pidió que hagamos un resumen sobre estos temas en un Prezi. Trabajé con Agustín Segura. Esta es nuestra presentación.

Movement in and out of cells

In Biology we have been studying the movement in and out the cells. Today experiment consisted on cutting strips of potatoes and soaking them in distilled water and a concentrated solution for 24 hours. Then we took another strip of potatoe that was not soaked in anything and then compared them. I work with Flor Araya and Rochi Hartmann. This are our results.

Potatoe in distilled water: This was the stiffest and least flexible potato because it absorbed water, therefore it swelled and became firm.

Natural potato: This potato was less stiff but more flexible than the one soaked in distilled water.

Potato in concentrated solution: This was the least stiff one of all and the most flexible.


On the Verge of War

In History we have already studied the short-term causes of WW2 and the failures of the League of Nations in the 1930´s. Now we have to work with some protagonists of the conflicts of the league before the beginning of WW2. For this, we had to create a Fakebook of one of the protagonists. I worked with Luli Giambruni, Delfi Miy Uranga and Joaco Venini and our protagonist was Haile Selassie.


“Fakebook” is a fake Facebook in which you can create a false profile of a character of a story or comedy that you like. In this case it is a profile of a history character that is call Haile Selassie.

Short Term Causes of WW2

For me this Meograph is well made and had a lot of information that can help to study the Short Term Causes of The Second World War.

WW2 Animation

This is a very interesting and entertaing video that helps  a lot to understand how the Second World War was developed and how countries attacked other territories. In the video is well explained the movements of the countries and how the allies in the USSR and the USA managed to recovered all their territories loosed.

Specialisation of cells

In our Biology class we  have started seen our new topic: Specialisation of cells. We have seen seven different tipes of cells. Ciliated cell, root hair cell, xylem vessels, palisade mesophyll cell, nerve cell, red blood cell and sperm and egg cell.

Ciliated Cell


Adaptation: It has a layer of tiny hair called “Cilia” which can move and push mucus from one place to another. The “Mucus” can transport trapped dust and microbes when it is pushed by the cilia.

Root Hair Cells

Adaptation: Plant roots have root hair cells for absorbing water and mineral salts.

Xylem Vessels


Adaptation: Transports water and supports the plant. The cell has no cytoplasm (so water can pass freely), no end wall (so that many cells can form a continuous tube) and walls strengthend with a waterproof substance called lignin.

Palisade Mesophyll Cells

Adaptation: Some plants have palisade mesophyll cells that contains chloroplasts to produce photosynthesis.

Nerve Cells

Adaptation: Animals have nerve cells to transmit information in the form of electrical impulses.

Red Blood Cells

Adaptation: Transports oxygen from the lungs to the tissues where aerobic respiration occurs. The cytoplasm is filled with the pigment haemoglobin, which carries oxygen. The cells have no nucleus, leaving more space for haemoglobin, and they are very flexible (They can be forced through even the narrowest of blood vessels).

Sperm and Egg Cells


In testes are sperms cells and in the ovaries are egg cells that contains the genetic material to trasnmit genetic information from the parents to the

The sperm has a tail which produces swimming movements to go to the egg cell.

The Woodspurge

In our literature class we have seen a poem call “The Woodspurge”, written by Dante Gabriel Rossetti and our teacher told us to compare this poem to “A Birthday” in relation with the tone, theme and the atmosphere. I work with Juan Ignacio Lutowicz.

A Birthday”

Theme: Self-expression;

Tone: Love, pacific and reflective;

Atmosphere: Happyness, full of love and joyful.

“The Woodspurge”

Theme: Grief and regret;

Tone: Sad and depress;

Atmosphere: Sadness and depression.

Living Oraginsm – Bird

In our Biology class we have learnt more about living organisms and their characteristics. Our teacher told us to work in pairs about one organism, in my case was a bird, ilustrate it and determine from which class it was. I work with Agustin Segura.



Class: Birds

Kingdom: Animalia

Phylum: Chordata


Animal and Plant Cell Structure.

In our class of Biology we have been studying the organisation of organism. In our last class on Wednesday we have seen how is the animal and cell structure and his finctions.
