Pupil Reflex

Our biology  teacher Male Ravagnan told us to get in pairs and work in our blogs. The topic is about the eye, specifically the pupil reflex. I worked with Delfi Nicora.

We found a video which explains this process.

Poem: Rooms

For our Literature Virtual Period our teacher Pato Chujman gave us a task on a poem by Charlotte Mew, ¨Rooms¨.

1- Why is it said that the life of the writer was a tragedy?

After reading Charlotte’s biography my answer would be that her life was a tragedy because she was surrounded by so many deaths and inconvenients, it is almost impossible to believe so much could happen to one person. She was the eldest sister from 7 brothers. Three of them died when they were just kids, they had a whole life ahead. Other two, one sister and one brother were commited to a mental hospital in their 20’s and stayed there for the rest of their lives. Up to here, Charlotte had already lost 5 brothers. The only kids left in the Mew family were her sister Anne and herself. Both sisters had decides they would never get married or have children because of the menta illness history in their family. A fw years later her father died, leaving the with almost no economic support. Soon they had to leave the house they were living in because it had been condemned. As if had not been enough rough times, Anne got ill with cancer and Charlotte had to take the responsibility of taking care of her and producing an income to pa for the medicines and food. A year later Anne died. This was the feather that broke the camel’s back. She became depressed and delusional, entered in a nursing home and soon after comitted suicide. Her life was really tragic, one bad episode after another.

2- How are “rooms” described?

In the poem rooms are described as being part of death as it says, adn I quote “rooms that have had their part in the steady slowing down of the heart” I took the risk and assumed that by “slowing down of the heart” the author meant to describe what the hearts does when the person has died. The rooms are also described as little, damp, as if they were very uncomfortable. It also makes a reference to the place in which these rooms arelocated when she writes “seaweed smell” and “sound of tides”, we would imagine this as somewhere relaxing, somewhere to rest, but Charlotte describes this rooms next to the sea in a negative way, she makes use of words such as “ceaseless”and “maddening” for example. They are also described as related to death and illness. I would also like to make account of something that might ot be related to the description of the rooms itselves but to the author’s life. When she writes “we (two) lie dead” it might be referring to the moment when she and her sister Anne were the onl ones left. Charlotte, reaching the end of the poem wrote, “other dustier, quieter bed” the use of the word “other” could be analysed as the poet expressing his or her tiredness or deillusionment, and by “dustier” I would say the writer is making reference to when they had to move to another house because the had run out of money. The last lines of this poem ” out there in the sun- in the rain” means that they have a safe place to stay, which protects us from the climate outside.

3-  ” But there is the room where we (two) lie dead, Though every morning we seem to wake and mightiest as well seem to sleep again”

“I remember rooms that have had their part in the steady slowing down of the heart”

4- The poem beginning with “I remember” makes me guess that the voice of the poem is talking about the past,  it is someone who has being through that situation but not any longer. The tone is somehow nostalgia and melancholic.

5- I believe that the theme dealing with this poem would be that of love and companionship.

Piece of writing: An Important Place

Our language teacher Daniela Barra gave us a writing task which consisted of getting in pairs with someone we shared an imortant place with. We had to describe the place, b making a story, a diary entry, a poem, a song or anything we wanted. After writing we had to say why that friend we chose plaed an important role in that place we had chosen. I worked with Delfi Nicora.

It was a hot dy in November, we were about to give a closure to our year in school, our first year as friends, when we experienced many different and new things.

There were for of us, each completely diferent from each other, yet shared a lot. That day we had decided to have a sleepover. One by one we arrived to our friend¨s house, Delfina Santayana. She was a girl who came from Brazil, it was her first year living in Argentina and had thought us the extremely different culture she was raised in.

It was late at night, her famiy was asleep so we decided to  go and talk in the balcony, which had a nice view of the 9 de Julio Avenue with all the lights on. We sat there and wonder what to do. Her mom had made home-made brownies so we took them outside with us, we played some music and started talking and laughing, remembering old anecdotes. We were having a lot of fun but the best was yet to come.

After dancing, laughing and doing all sort of things we sat down. As we were thinking, an idea came up. We had to think of moments where we had gotten to know each other better. And there we sat sharing anecdotes not all of us knew, soon we were aproaching a more serious atmosphere. As we spoke about those stories, we aso realized that there were some thing we didn¨t felt comfortable with, or maybe attitudes that once harmed us. It was the perfect time to talk about them, politely and respecting each other opnions. We sat in a circle and one by one we started relfecting. To cheer up the night a little bit, after we said the things we didnt like baout each other and each gave her point of view, we also said the things we loved the most about the other person, why we thought they were valuable. It was nice because we didnt fight, we listened and appreciated the things we said. That simple conversation became one full of our deepest thoughts, secrets, worries and joys, we really got to know each other in a different way.

In order to relax a little bit, we went for a walk and laughed again, remembering old memories, and without even noticing, creating new ones. When we got back it was almost twilight so we made popcorn and watched some movies. It was a great night.

Epi was an important part of this place we shared because she put her good will and commited to sharing her secrets and private life too. She was also imortant because as a matter of fact she is part of the group we created, part of that union which had been fortified that night.

Ensayo 1

Nuestra profesora de Literatura, Camila Aliberti nos propuso empezar el trimestre haciendo un ensayo, practicando nuestra habilidad para realizar estos mismos.

La frase que en este caso elegi para escrbir mi ensayo fue ¨Uno es dueño de sus silencios y esclavo de sus palabras¨.

“Cada uno es dueño de sus silencios y esclavo de sus palabras”, esta frase o consejo o advertencia, cada cual le pondra un nombre de acuerdo a su propia perspectiva, viene pasando de boca en boca a lo largo de los años.

Esta frase finalmente, llega a mí, una adolescente de 16 años, con la característica rebeldía, pasión e impuslividad inocente de esta etapa en mi vida. ¿Como entiendo yo, o como la interpreto a esta frase? Por empezar yo creo que los silencios crean un gran impacto, en la persona que calla tanto como en la que recibe esa nada ensordecedora como respuesta. Cuando se habla de que uno es dueño de sus silencios yo interpreté basándome en mi poca experiencia de vida, que cada uno elije cuando, por que y hacia quien van dirigidos esos silencios. Pero no estoy de acuerdo completamente, creo que también los silencios son, a veces, incontrolables. Digo esto porque me pasó a veces sentir tanto dolor o enojo hasta a veces envidia, que mi cabeza no lograba poner en palabras lo que sentía y no me quedaba nada mas que callar, en este caso mis silencios eran involuntarios. Pero por otro lado creo que hay silencios que sí elegimos causar, esos silencios que crean indiferencia, ignorancia, que quieren causar dolor o castigar al otro, tanto como los que son para dar una muestra de respeto hacia el otro. Ambos son silencios voluntarios.

Al decir que somos esclavos de nuestras palabras yo pensé directamente en un ejemplo concreto, una vez que habia discutido con mi mamá y conteste mal, en consecuencia mi mamá se enojó y sufri las consecuencias. Esta parte de la frase yo creo que es verdad completamente, al contrario de los silencios, las palabras dan mas que pensar, las veo como si estuvieran mas en la superficie de una persona, en la punta de la lengua y por el contrario a los silencios me los imagino en el fondo de la garganta, como un nudo. Estoy de acuerdo con esto de ser “esclavos” de nuestras palabras porque para mi es más fácil culpar a la otra persona si tenemos algo concreto, palabras, la superficie de la persona, algo facil de interpretar pero al mismo tiempo con tantas interpretaciones diferentes e individuales. Creo que las palabras causan daño más rápido aunque debatiría que los silencios causan daño mas profundo.

En conclusión los silencios tienen una amplia interpretación aunque es más dificil llegar a ellos y pueden ser tanto voluntarios como involuntarios, en cambio las palabras son voluntarias, superficiales y con un rápidez mayor que la de los silencios en causar un impacto en las personas, pero estas palabras nos esclavizan porque nos dejan vulnerables.

Excretion and Kidneys

In biology we are preparing for the IGCSE. Our teacher Male Ravagnan gave us some activities on her blog about Excretion and Kidneys, and we worked with them during the lesson.

  • Excretion as removal from organisms of the waste products of metabolism (chemical reactions in cells including respiration), toxic materials, and substances in excess of requirements.
  • Egestion as the passing out of food that has not been digested or absorbed, as faeces, through the anus

Urea is formed in the liver from excess amino acids.

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. 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.

Specialization of Cells

PLANT CELLS:

Ciliated Cell

ciliated

Has a layer of tiny hairs (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

root hair

Absorbs minerals and water from the soil water. This cell has a long extension (a root hair) which increases the surface area of absorption of materials.

Xylem Vessels

xylem vessel

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

palisade mesophyll

It is found beneath the epidermis of a leaf and contains a lot of chloroplasts as its function is to carry out photosynthesis.

 

ANIMAL CELLS:

Nerve Cells

nerve

Conducts nerve impluses. The cell has a long fibre called an axon along which impulses a travel, a shatty sheath which gives electrical insulation and a many-branched ending which can connect with many other cells.

Red Blood Cells

red blood

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

sperm and egg

egg and sperm

Sperm Cell: It has a long tale called flagellum which allows the cell to swim through the female reproduction system. It’s neck is full of mitochondria to give energy so that the flagellum can move.

Egg Cell: it has a jelly-like layer around it and outside the membrane for protection and it is full of cytoplasm.

Ghost Story

Our language teacher Pilar gave us the task of writing a ghost story using a technological device or editing app, including the vocabulary we have been studying this term. I used iMovie.

Here is my story, hope you get scared!

Animal and Plant Cell

Since in our biology class we have been studying Cells and their organels, our teacher,  Magdalena Ravagnan, told us to do some activities  that she put in her blog.

 

The first acivity was to construct a Venn diagram and show the differences and similarities between animal and plant cells.

 

The second activity was to state the functions of the structures in the plant cell and in the animal cell.

Functions of the Organels:

  •  CELL MEMBRANE: encloses the cytoplasm and stops it from flowing out; controls which substances can get in and out of the cell (it is partially membrane).
  • CYTOPLASM: contains all the organelles and the chemical reactions take place in it.
  • NUCLEUS: stores the genetic information.
  • CELL WALL: maintains the shape of plant cells, supports and strengthens plants, it is fully permeable.
  • VACUOLE: contains a solution of sugars and salts named cell sap.
  • MITOCHONDRIA: Inside them, oxygen is used to release energy from glucose, in the process of aerobic respiration.
  • RYBOSOMES: produce and contain proteins.
  • CHLOROPLASTS: contain a green pigment called Clorophyll which absorbs solar energy that is used for making food for the plants by photosynthesis.

Online Test

La Our language teacher, Pilar Pando prepared for us an online test about some of the topics we have seen this previous months.

The first task was to do an inphographic including the main characteristics of the Gothic Novel as a genre and to name at least two relevant pieces of work and their writers.

Here is my work

The other task was to imagine you had to interview one of the  authors of these stories: The Cask of Amontillado, The Monkey’s Paw and The Yellow Wall Paper, to choose one and to find out about him/her and write the interview.

D: I am here with Charlotte Perkins, so how are you?
C:Good morning, i’m good, excited about this interview.
D:I would like to get to know you more, could it be?
C:No problem, I am all ears
D: Tell me about your childhood.
C:I was born in Hartford, iConnecticut and I had a happy life and loving family.
D: What do you make a living of?
C:I am a writer of short stories poetry and nonfiction.
D: Which was the most famous piece of write?
C:The most famous pice of write was The Yellow Wall Paper, I think it is because there was a message I wanted to transmit to all the future generations.
D:And what did you transmit?
C:The woman’s life in the 19 century is more a feminist kind of text, defending the womans position in everyday life.
D:Okay, and tell me are you engaged or married?
C:Yes! Igot married in 1884 with Charles Stetson.
D: Do you have kids?
C: I do, a little girl.
D:Where did you get your inspiration from?
C: My father,Fredrick Perkins, he was a librarian so I learnt a lot from him.
D: Good to know! It was lovely meeting you.

Online Language Test

We had to do an online test for our Language Assignment which its topic is about Benjamin Zephaniah, also the author of Face the book we are reading.

Sos (Save our Sons)

1- This poem is about black people who live in England. In this poem Benjamin talks about rascism and discrimination against his people. He says “We black men of England, too proud to cry for shame” by this I understood that he was saying that they acted indifferent in some unfair situations, that they didn’t argue for what they stood up for. Benjamin also says ” The bad talk and the cool walk will not keep us out of jail”  meaning that they had to change their ways in order to be treated more fairly. 

Benjamin makes use of hyperboles in order to exaggerate and emphasise phrases, for example in “Let’s cry a sea” because nobody actually cries a sea, it’s a way of saying that he encourages his people to cry a lot. He also makes use of rhyme to make it more enjoyable.

I chose this poem because I liked the idea that he teaches his people to become better ones, to fight politely for their rights and he shows that he cares for them. I really like how Benjamin writes because he is always in search of justice for everyone.

2- There  was once a girl

Whose face was covered in scars and

Purple bruises which then turned into grey.

It was impossible to stare at such a horrible thing

But she still dared to come school and show her skin.


Every kid in school stood away her

And she dealt with it until she became depressed.

Her loneliness consumed her 

Until one day she took her life away.


Had I know how bad she felt

Would I have helped being her friend.
