The subject that I enjoyed studying this semester is chemistry. This subject is the science that study the composition, structure and properties of matter, and changes of energy that experiment the matter during a chemical reaction. This subject, it's useful specially in the medicine, because thanks to the chemistry, it's possible to create the medicines for many disseases. I love this subject for many reasons. Fisrt, I have to say that I love study chemistry since I start to have this subject in the school. At the begging, it wasn't easy to me undersand this subject, because it was something new to me (the structure of the atom, the chemical reactions, and others). I really wanted to understand it, so I study very hard, until I finally did it. I think that it's importat understand this subject from the beginning, because if you don't understand the basic concepts, it's going to be so difficult understand the topics that will be seen in later years. I think ...

Now that I'm in the university, it's so important that you use reliable and certified internet pages. One of my favourites pages to search information for is  SciELO. This page, has a lot of papers and articles about many things, a lot of them are experiments with animals, or studies based on people. I like this page because it's in Spanish, and it's easier for me to search for the information in cases of emergency. I'm using this page so much because I have to make an ABP, that is an oral presentation about some topic that your teacher gives you. In my case, I have to talk about pesticides and malformations, and there isn't so much information about that, or at least, nothing concrete. For that reason, this page has helped me a lot, because it has a lot of experiments with animals and epidemiological studies. Since I discovered this page,  I look up information about this topics at least 1 time a week, and every time I discover new studies. I recomend this pa...

Hi everyone! today I would like to share with you which is my favourite place in Chile. This place is La Serena. I love this place for many reasons. First, since I was little I always go on vacacions there, so I think that I know this place so well. What most I like about La Serena are its beaches, especially totoralillo, the sea in that place is fantastic. When I go on vacacion to La Serena, I usually stay there for 2 or 3 weeks, and I usually go with my family. The last summer, I went with my friends, because one of them has a house there, so we stay for a week. That week, I knew another parts, because when I go with my parents, they just want to be in the beach. With my friends went to eat to some differents restaurants, we went to party, and we did differents activities such riding on roller skates or taking a boad ride. If you don't know this place yet, I invite you to go, it's very beautiful and you won't regreat it.

In this photo, I'm standing with one of my best friends in a waterfall from Cajon del maipo. We went this year, in summer holidays; she invited me to her house in this place, and we went with all his family. I'm not sure, but I think that this picture was took for his cousin, and I remember that we were planning to pose for the photo, but it was impossible because it was a lot of wind. I love this picture for many reasons. First, because I've never been in this place before, and I loved it. I think that it was a really beautiful place to took a photograph, and I remember, that it was a very peaceful and relaxing place. Another reason it's because it's a spontaneous photo, in wich we appear laughning and having a good time like always when we are together, besides we don't have many photos together, because we don't have so much time to get togheter, thinking that we know each other only since last year, in the pre-university. The last reason it's bec...

Hi everyone! today I'm going to talk about my favorite film, called "Always by your side (Hachiko)". I think that most people have seen this movie, especially if you love the dogs. There's so much reasons why I love this movie, and why it's my favorite. First, I have to say that I love the dogs, whatever their race, and with this movie I confirm that a dog can really be the most faithful animal in the world. The history, it's so well narred and starred, that it's impossible for you don't be moved with it, and that's the fisrt reason why it's my favorite movie. Secondly, beacuse the movie it's based in a true story, where a dog called Hachiko (like in the movie) waited for his owner in the same place, at the same time, and every day until the day of his death. Knowing that it isn't a fictional history, allows you to move even more with the movie. And the third reason, it's a little bit masochistic. I love watch this movie the ...

I use so many types of techonoly in my day to day, and since I'm living with my uncle, I spent the majority of the time alone, so I don't have so much time to cook my food, so I buy frozen food, or keep food that my mom cook during the week in the refrigerator and when I come to my uncle's home, I put it in the microwave to eat it after. If I have to choose some piece of technology, I would have to choose the cellphone. I've started to use it when I have 10 years old and since that day, I couldn't leave it. Technically, I can use it to everything. In holidays I use it so much more, to see videos in Youtube, to talk with my friends, or to use instagram. But now that I'm the university, it's essential for me to another uses. Although I don't have so much time now to see videos, or see instagram, I use it to look for information about something realtioned with some subject. To me, it's easier to use than the computer, because it's faster and I got...

When I was a child, I didnt know exactly what I  wanted to study. I always liked maths, and chemistry, but never found a carrer connected with that subjects that I really  liked  Although I like biology, I was never so fan of that asignature, or at least not like maths or chemistry, but I was clear that I liked so much the science, and the investigation, so I start to investigate about health carreers, and one of that called my attention: the nutricion. My sister it's a nutricionist, and I always loved what she was studying. I always investigate about food, their components, how to have a healthy diet, etc. Actually I still love that topics, but now, found a job in that area its so complicated, because they'are so much nutricionist in Chile , so I discarded it. One day, I was looking the TV, and i saw a girl that was a dentist, and started to talk about the carrer, since that day, i'm in love with the odontology. The part that I most like about this carrer, is th...
