Short term causes to World War 2

This are the presentations my partners and I did on the short term causes to World War 2. We were divided into groups ans asigned different causes to analyze. each grup made a presentation and then presented to the rest of the class during history.

I worked on the Nazi Soviet Pact, that was the last cause to the war, with Tin Reynal, Agustin Bravo and Juan Stordeur. 


This is the presentation made on Rearmament by Salvador, Juan Cruz, Trinidad Torrendel, and Feli Donato

This is the presentation on Rhineland made by Fran Costamagna, Vicky Quiroga, Euge Kenny and Mati Giambruni.

This is the presentation on the Anschluss made by Lucia Frias, Clara Allende, Lucas Caputo, Malena Millan.

This is the presenation made on Czechoslovakia by Josefina Tasca, Felix Okecki, Gaston Posse and Tota Lupi.

Movement in and out of cells

During our biology class we studied movement in and out of cells, Diffusion, Osmosis and Active Transport. We used this website to understand the different processes, completed the games and made a comparative chart for the different movements.

Type of molecules Water Ions, gases, other molecules Ions, gases, other molecules
Concentration gradient Down a water potential. High to low Down a concentration gradient. High to low Against concentration gradient
Energy NO NO YES

Leyendo sobre el INTI y el INTA

En nuestra clase de físicoquimica, con nuestra profesora Susana Perez Rey, leímos artículos sobre el INTI (Instituto Nacional de Tecnología Industrial) y el INTA (Instituto Nacional de Tecnología Agropecuaria). Como consigna nos dio elegir un articulo de cada pagina, hacer un resumen del articulo y un comentario personal.

Sobre el INTI elegi un articulo que trata de la impresion 3D que se llama: “Panorama de la impresion 3D”. Fue de los primeros articulos que leimos y de los mas interesantes para mi.

El articulo cuenta que ahora el INTI cuenta con impresoras 3D, y ofrece a las industrias servicios de impresión 3D, que hasta ahora solo estaban disponibles en el exterior. Aunque la impresión 3D es una realidad hace ya 35 años, fue solo en esta ultima década que se implemento mas en lo que son las industrias y agendas publicas. El aumento del la impresión 3D se debe a los usos que se le han encontrado, tanto en industrias en las que crean diseños de nuevos productos hasta en hospitales para implantes médicos. Gracias a la impresión se podrán sustituir importaciones. Existen grandes variedades de impresión, y depende del consumidor elegir la mas apropiada para el uso que se le va dar. Es importante conocer las posibilidades de la impresión 3D, y saber cuales son las consecuencias de su uso.

Creo que la impresión 3D traerá muchos cambios, tanto en la industria como en la vida cotidiana de muchas personas. Se le podrá múltiples usos, tanto para diseños y usos personales y como ya se menciona el articulo implantes médicos.

Sobre el INTA elegí un artículo que trata sobre la desertificación del suelo y como combatirla, “Especies Nativas” se llama el artículo, es en forma de video.

Adriana Beider nos cuenta en el vídeo como en la Patagonia están trabajando para combatir la desertificación del suelo. La desertificación ocurre cuando plantamos una planta, somo la soja que es muy común en la Argentina, y como toda planta luego cosechamos para consumo, el suelo después de la cosecha queda sin nutrientes y demás elementos que necesitan las plantas para crecer debidamente. En esos casos es cuando interviene el hombre y ayuda a que el suelo recupere los nutrientes y demás elementos, tanto artificialmente como naturalmente. Lo que Adriana propone es el uso de plantas que crecen rápido y dan semillas que pueden consumirse, pero no usan tantos nutrientes o elementos. De esta forma el suelo recupera elementos importantes y producimos otros productos, resolviendo asi una importante problemática en cuanto a la desertificación.

En mi opinión la solución que han brindado a esta gran problemática es muy buena, permiten que la tierra recupere naturalmente nutrientes y otros elementos con la producción de productos agrícolas que no necesitan sustento del suelo, dejando así afuera la nutrición artificial del suelo, que como sabemos no es buena para la vegetación y mucho menos para nosotros como consumidores.

Food Tests

During our Biology class we went to the lab where we tested milk for, starch, using iodine solution, reducing sugars, using benedict solution and also proteins using biuret solution and bioling it for two minitues. Our conclusion were that milk does not contain starch, it contains reducing sugars and proteins. We completed the charts below and took some pictures during and after the expirement.

A Iodine Solution White Orange Starch is not present
B Benedict Solution White Purple Milk contains reducing sugars
C Biuret Solution White Orange/Yellow Proteins are present


Test for starch iodine solution Orange Black
Test for protein biuret solution Blue Orange/Yellow
Test for reducing sugars benedict solution Blue Purple

This are all three different test tubes with milk and the different solutions we used to test for components.

These are all the test tubes when the tests are completed, we can see that milk only contains reducing sugars and proteins.

  These are the test tubes when the solutions are added 

Revision Unit 1

Our teacher Maria gave this questions to answer on the unit we finished reading on Business, Revision Unit 1

A. Human needs are: shelter, clean water, clothing. It is essential for every human being to have somewhere to sleep and protect from the cold or rain. It is also crucial for us to drink water, dehydration is a dangerous thing, and clothing is also very important to stay cover, such as from the cold winter.

Human wants are: luxury house, coca-cola, car, designer jeans. It is not a need for a us to have a big house, with many rooms and nice things, coca-cola is a tasteful drink, but not essential, and designer jeans are something only those with money use, no all of us have them and we don’t need them.

B. In all countries there are wants and needs that need to be fulfilled, to make all of these goods and services there are factors of production, land, labour, capital, enterprise, which are limited. As there is never enough land or capital to fulfil the needs and wants of the population, there is an economic problem of scarcity.

C. Land: natural resources provided by nature, such as oil, land, forests, gas, metals.

Labour: people available to make products.

Capital: finance, machinery and equipment used for manufacture of goods.

Enterprise: the person who brings the resources and factors of production together to produce a good or a service, such as the owner of a business, known as an entrepreneur.

D. Let’s imagine someone that has $1000 and wants to buy a new pair of shoes and phone, so he goes to store and the phone is $700 and the shoes are $500, he does not have enough money to pay both the phone and the shoes, so he chooses to buy the shoes, the phone would be the opportunity cost. Opportunity cost is the best alternative given up by choosing.

E. A group of students has to decide whether to go to Entre Rios, by bus and make a two days stop in the Termas, or go directly to a camping site in Entre Rios by Plane. The students decide to go to Entre Rios by bus and stop for two days in the Termas, as they have never been there. The air plane is the opportunity cost.

A group of tourists visiting Rome are asked by the guide whether they would like to go see Fontana de Trevi or visit the Colosseum . They decide to go to the Colosseum, which is bigger and takes longer to visit. Seeing Fontana de Trevi would be the opportunity cost.

F. Division of labour is when the production is divided into the making of different jobs and making each worker a specialist at just one task.

G. Why is a business likely to increase output if it adopts division of labour? It is likely for a business to increase output if it adopts division of labour because, having different workers doing different tasks and then putting them together to have the final product is faster than having one person doing the whole product by himself.

H. Mixing the eggs and the milk, adding the flour, adding the mix to a mould, putting the mould in he oven.

I. Three benefits from business activity can be: products that satisfy the needs and wants of people, they give jobs to unemployed people, when you pay for a product you are also paying taxes that then help society.

J. Added value is the difference of money there is between the selling price of a product and the cost of bought in materials and components that the product has.

K. You can make the product with cheaper products, or something that makes it different, such as making it hand made, you will be earning more money.
