SCIENCE WEEK

In the science week the two courses of 1º ESO we will make sundials, also draw differents types of mushrooms and we have already prepared the crystallization experiment, the course of 1ºA a was already finished their crystallization experiment first, with very nice crystals, but us 1ºB, make again the crystallization experiment, recrystallization, and it was worth it because we got showy and amazing crystals. 

We will take photos about science week.

Science week: 25-29 of April

Photos of crystallization experiment 1º ESO B (final crystals)

Planets are formed from clusters of dust and expanding gas around young stars. Small grains of dust and gas bags end up crowding out effect of gravity and forming ever larger agglomerations give rise to asteroids and planets has not yet begun to burn hydrogen in its core . It has been found that there is now a new planet forming around a star.In meters around those images of VLA is where astronomers have detected the protoplanet, an accumulation of matter at a distance from the star about 10 times the distance from Earth the Sun, and that will already have a mass of between three and eight times that of our planet.

TOP:5 MOST POISONOUS MUSHROOMS OF THE WORLD!

Hi!
In the last class,teacher Quesada was speaking our about mushrooms and,little by little,we ended up talking about poisonous mushromms!

What are poisonous mushrooms?
Poisonous mushrooms are dangerous organisms,that can kill or produce a disease to anyone!

Here you have a good example,the Amanita Muscarita

It is a very very poisonous mushroom,did you hear about it some time?

So,we are going to present you a top of 5 poisonous mushrooms,let´s go!

(1) Amanita Phalloides : It is the most deadly mushroom for humans, I fate killed many people , because the toxins act on the liver and kidneys, slowly killing humans.

(2) Russula emetica: Cause mild stomach disorders from half to two toxic horas.Es only lots of it.

(3) Cortinarius: They are not ver comun,and not all are so dangerous,but there are others that are very poisonous.They produce headaches,tiredness and loss o apetite about many weeks.

(4) Boletus satanas: It is not lethal,but it cans produce vomit and indigestion.

(5) Lactarius torminosus: It isn´t very dangerous,so it cans only produce symptons of bellyache,from 15 minutes to 3 hours after eat it.

THE END

I hope you like it!
Which mushroom do you think that is most dangerous?

What was before,the egg or the chicken?

It is a very complicated question.

But... Why?

Because,a person can think that the answer stay in internet,and,later to read it,this person "knows" the aswer. But... What do you think about the possibility that another person could think that the answer is not completely studied?

Greek philosopher Aristotle (Aristóteles) always said that is always present before the potential, the man always precedes the sperm, and the chicken precedes the egg.

Really, a lot of philosophers,scientifics and other persons have a lot of explanation for this answer,but... I am going to choose the most "popular answer" so... Are you ready?

The first chicken could to leave a chiken´s egg.

So,the correct anser about it,is,definitely that the egg was before tha chicken

So,after this,I would like that you comment about this item.

What do you think could have been first, the chicken or the egg?

THE STARS.

The stras are spherical heavenly bodies formed by enormous quantities of gases and that issue own light. The stras have three characteristics that are: color, size and sheen.
Color: it depends on the temperature of the star, and goes from the blue of 30.000º C, up to the red one of 3.000º C. And always the cores of the stars have a much higher temperature.
Size: compared the size of the stars with the Sun, they classify under giants, very much major that the Sun, medians like the Sun and dwarfs are smaller than the Sun.
Sheen: it depends on the distance to the one that is the star of the Earth. Beyond, lees I shine and more nearby, more I shine.
The origin and the death of the stars.
·The stars are formed with the cloudy ones on having be compacted in certain zones.
·The death of an star happens when it exhausts his fuel. His end depends on his mass.
Our star is the Sun.

 

On 27 of november , I saw how Jupiter eclipsed Io.
First, I located Jupiter with my telescope. Later, I saw where was Io, and I saw how Io saw it time less. Roemer, in the year 1676, discovered the velocity of the light thanks to the eclipses of Io.

Carina Nebula.

Picture of Carina Nebula



The second brightest star of the sky is located in Carina Nebula.

Is one of the most massive stars of the Galaxy. Its name is Carinae (canopo) is a white-yellow  supergigant, at 310 light years distance.



The Milky Way crosses Carina, the Constellation contains several open clusters,  such as NGC 2516 and IC 2602. This last one is known as the "Southern Pleiades".

The Milky Way

The Milky Way is the galaxy that contains our Solar System. It is a spiral galaxy and contains between 200.000 and 400.000 million stars, and 100.000 million planets.
The Milky Way has got three parts: the halo, the spiral arms and the galactic center. 
The spiral arms contain a lot of interstellar gas and dust. Our Sun is there, in the Orion Arm.
The galactic center is the Milky Way's center. It consists on millions of old stars.
The halo rounds the galaxy. It has got isolated stars. 
You can see the Milky Way as a band of white light in the sky at night, but it is difficult because there is a lot of contamination.

The Eclipses

An eclipse can be from Moon or from Sun.
When is the Moon. The Earth is between the Sun and the Moon. The shadow from the Earth cover the Moon and in a part of the Earth the Moon don't see. An eclipes of Moon, can be partial and total.
When is the Sun. The Moon is between the Sun and the Earth. The shadow from the Moon cover the Earth, and in a part of the Earth the Sun don't see. An eclipse of Sun, can be partial, total or annular.

Oceans , such as forests , capture emissions of carbon is a phenomenon that can endanger the survival of coral habitats and threatened animals that live in the emissions of carbon dioxide generated by human activity . However , in the case of the deep sea, the accumulation of this gas results in an increase in the acidity of the seas. An average increase of almost 30 % since the industrial revolution began its journey , over 200 years ago. And that by the end of the century can reach 150% . Thiss a phenomenon that can endanger the survival of coral habitats and threatened animals that live in them

dicover part of the matter in the big bang

;The dimensions of the universe are difficult to understand. 1,300,000 Land many of them larger than our star to reach the volume of the Sun, would be needed and it is estimated that only in the Milky Way, the galaxy we inhabit, contains more than 200,000 million stars. Yet these stars do not involve much more than 8% of normal matter  that was created at the origin of the cosmos and are made of human or planets. The remaining 90% are ionized gas clouds in which the temperature has separated electrons protons. Despite the enormous amount of matter in these clouds until now had only been able to detect between 20 and 30% of the content of the universe, the part that was hot enough to be seen with X-ray telescopes The rest remained undetectable, such as dark matter.

Welcome to Science

Hello to everybody and welcome to our new blog. As you know, we have a blog for our classes but this is just for you, for the students. Here you can write about whatever you like related to Science. Astronomy, Biology, Geology, Phisics, Chemistry... and of course about what we do in our clases. And as you are bilingual students, you are going to write in English. It doesn't matter if you have some mistakes; the most important thing is thinking and writing in English. In my opinion this is a good aim to learn both Science and English. So, we are willing to read your posts.

Best regards.
