El Mar Muerto

El mar muerto es un mar situado entre Jordania e Israel.

El Mar Muerto es famoso por ser el mar mas salado del mundo y también es rico en  calcio, magnesio, potasio y bromo. Este mar lamentablemente afecta a la biodiversidad, ya que la constante niebla y los 400 metros extras de atmósfera ayudan a que se filtren más rayos UBV, los cuales causan quemaduras de sol, además, que el Mar Muerto esté desapareciendo afecta al ecosistema cerca del mar.  El mar esta relacionado con la densidad ya que tiene tanta sal que el agua no puede disolverla, y por eso hay densidad en el agua y por eso la gente flota fácilmente cuando se mete.

Densidad en acción

En la clase de Ciencias Naturales, fuimos al laboratorio a experimentar algunos temas trabajados en clase como la capilaridad y densidad. A continuación podrán ver algunas imágenes de como trabajamos con el huevo en el laboratorio

Para entender el concepto de densidad utilizamos:

• Un huevo.
• Una cuchara.
• Un frasco.
• Sal.
• Agua.

Colocamos un huevo en un frasco con agua.

Le agregamos sal.

Luego lo batimos.

Esperamos a ver los resultados.

Le agregamos más sal.

Lo batimos nuevamente.

Observamos los cambios y el huevo flotaba gracias a la densidad.

Le agregamos agua que disolvió las sal y por eso el huevo descendió pero seguía flotando.

Arriba la capilaridad

La capilaridad es la capacidad que poseen los líquidos de avanzar o ascender por espacios muy pequeños, ya que espacios (vasos, tubos, etc.) permiten que las moléculas de dicho liquido “trepen” en su interior. Sirve para cosas como para que las plantas transporten el agua desde su raíz hasta sus hojas para realizar la fotosíntesis o para que la sangre que vuelve al corazón se transporte, entre otras cosas. A continuación, podremos ver el fenómeno en un trabajo practico:

Our Myth

2nd part: Belén.

3rd part: Tomás.

4th part: Azarías.

1^st Part

Poseidon was the god of water and he was married to Athena, the goddess of wildlife. It was Poseidon’s wife birthday and he wanted to give her a very beautiful gift. so he started thinking what he could  buy to her. He thought of a necklace, a bracelet or earrings but he couldn’t decide .he didn't find the right gift to give her.

Poseidon said: “But I do not think that jewelry will be the perfect gift. It has to be special because she is special . What can I do? I don’t want her to be sad because I love her too much and as I said before, it has to be special”.

2^nd Part

Poseidon: “Oh, my dear, your birthday is tomorrow and I don´t know what to give you. please, tell me what you want for your birthday”.

Athena: “Give me what you want, anything from you is ok”.

Poseidon: “give me an idea, something you like for example”.

Athena: “Everything you create or give me  will be enough for me”.

He thought all day and all night and he continued without knowing what to give her, but he decided it would have to be something special. so he decided to create something. He thought about something related to his son, Perseus, but he remembered that she told him not to involve him.

3^rd Part

One day, Poseidon was walking on the streets of Athena and saw a fallen bucket leaking water. In that moment, he had a great idea. He would create something like that, but bigger, natural and with more water. He knew the right place to create it, so he went there immediately.

When he arrived at the mountain he saw a big place without trees an decided it was the right place to create it. He cut that part of the mountain so it became a cliff and created a river on top of it. The water started falling and made a lake. He watched it for some minutes and thought: “She will love it! But, how shall I name it? Ah, I know! This will be a “waterfall””.

4^th Part

After he invented the first waterfall he went back home happily and ready to give his wife his present.”This waterfall Is very funny!  can you create another one? i love it! “ his friend ? said

“Well I am going to  try.

next month if I can do it, we will finish creating more. Only then, you can come”.

“Oh yes will be great! I will come with my family and we will distract and enjoy this beatiful waterfall.”

“Ok don't forget to come.”

“Next month we will finish with the watrefall so come.”

La importancia del H2O para los seres vivos.

En Ciencias Naturales buscamos información sobre el agua y su importancia para los seres vivos. Después, realizamos un mapa conceptual explicando esa información sobre porque el agua es tan importante para nosotros. Acá esta mi mapa conceptual:



Luego de realizar el mapa conceptual,utilizamos la misma información para hacer un mapa visual (muchas imágenes y poco texto). Este es el mío:

Our Fable

In Writing, was wrote a fable in groups and I had to write the 1st part:

Once upon a time in ZebraVille there was a happy couple of zebras. They were Peter, a black with white stripes zebra with big blue eyes; Peter was also a good zebra. There was also Roxy, a god zebra, but she wasn´t so cute, she was white with black stripes and little black eyes. On another part of the town there was another zebra couple: Michelle, who was a black with white stripes zebra with green eyes, but she wasn’t a good zebra, her boyfriend was Alan another ugly zebra, he was white with black stripes and grey eyes, and he was also a good zebra.

Moral: "Be happy with what you have".

Para vos, ¿qué es la salud?

Grabé a un profesor y una profesora del colegio preguntándoles que era la salud para ellos.
