Presentation on Cocaine

In our Biology class we have been studying drgus; I had to make a presentation about Cocaine with Agos, Cata and Gonzalo. We explained the main concepts and ideas of this drug, its effects, and a case of a famous person which was addicted to it. We made an Easel.ly, hope you like it.

What are the important places in your life?

In our Language class we worked in pairs and brainstormed ideas about an important place for us. Then individually we had to write a piece about the place and why it is important for us. I worked with Catu, and we did a poem.

The four of us alone in the grass,

far away from our class

we enjoyed our time together

and did´t care about the weather

We told each other secrets during the night,

and woke up early to enjoy the light

we went there to isolate ourselvs

and therefore, connect with our inner self.

Once we all took a bath,

it cleared our head from the class of math

during the day we had long walks,

and during the night deep talks.

The Eye as a Sense Organ

In our biology class we have been studying the eye. This is an activity me and Catu Grosso did. We watched the animations in Male’s blog and answered the questions in the booklet. 

This is the video we found for question 6.

Our flow chart: 

bright light – cones in retina – brain – muscles in iris

*effect: circular muscles contract, radial muscles relax. These are antagonist muscles, muscles that work against each other.

*response: pupil constricts.

dim light – rods in retina – brain – muscles in iris

*effect: circular muscles relax, radial muscles contract.

*response: pupil dilates.

9) 2)b) When object O comes closer to the eye, the ciliary muscle contracts, the suspensory ligaments are slackened (are loose), and so the lens is allowed to bulge.

4)a) ciliary muscle contracts – allows lens to become fatter for focusing on close objects. (ACCOMMODATION)

iris circular muscle contracts – pupil constricts (PUPIL REFLEX)

5)a i) They detect light and send it to the brain as electrical impulses. (Change light into electrical impulses)

ii) Rod cells are sensitive to dim light but do not respond to colours. Cones are sensitive to bright light and distinguish different colours of light (blu, red and green).

b) sensory neurone. They have a long axon, this way they can send the impulses to the brain.

c) Cornea, lens, retina.

d) i) biseps contracts and triceps relaxes.

 

 

Essay On “The Yellow Wallpaper”

On our Literature class we’ve been analysing the story The Yellow Wallpaper by Charlotte Gilman. And we were asked to write an essay based on an aspect discussed in class, but not to write the final conclusion.  I worked with Gonzalo Vazquez Avila. Hope you like it!

In the story The Yellow Wallpaper by Charlotte Gilman, John, the husband of the narrator is known to be the villain of the story. Because he, as a ‘physician of high standing’ assures his wife is going through a nervous depression, and locks her up and vetoes her wish to write and relate to other people; because he’s sure this will help her recover. He trapped his wife and left her alone, but only for her to get better. So up to what point is he the villain?

To begin with, we know for certain, that John, through his knowledge as a physician, did what he thought was best for his wife’s health. As the narrator says at the beginning of the story, he was “practical in the extreme”, he believed isolating her wife was the solution so no matter what she said or what she did, he did not let her out of the land. He thought what he was doing was right, and she would eventually get better, but she wasn’t in the slightest; not until she broke free.
Furthermore, we know he cared deeply for his wife’s health and did what he believed was right for her, though he couldn’t help her at all simply because he didn’t think he needed his wife’s opinion, which was his first mistake. He ignored her when she wanted to express herself, “…John would not hear of it”, and told him what she really needed, what she really was going through, but there was no case. Without the point of view of the diseased, it is very difficult to know exactly what goes through that person’s mind and spirit.

Despite this, we must hand it to him, he does shine at some moments and does little things for his wife that he doesn’t know mean so much for her. Like when she tried her best to express her needs but failed when she started crying uncontrollably, and then he “…gathered me up in his arms, and just carried me upstairs and laid me on the bed, and sat by me and read to me till he tired my head”, he, without the use of medicine, did what was best for his wife. It is in this moments that we come to respect John, and we understand that everything he does, he does for his love.

In contrast, the woman heard what her husband was saying, and realized he was wrong, but decided not to act upon it. She trusted him, and so she fought with herself to get better under the conditions her husband gave her, “he takes all care for me, and so I feel basely ungrateful not to value it more.”, she put up with everything John said because she knew he wanted only the best for her, and so she accepted everything, not being able to go out of the land, not being able to talk to anyone, not being able to write. She loved him, so he stuck to him, even though he was hurting her.
