Black Holes

The amazing phenomenon of black holes was a great mystery before Stephen Hawking made an investigation. Black holes are the result of the death of a star because when the star dies it triggers a supernova explosion. Black holes are very famous for their great gravitational force, they are so strong that they can absorb light. Then, it is said that black holes fit the particles and, as there is no light, they are black.

They are very different from the wormhole because the two act differently.

One sucks and the other takes you to another dimension or part of the universe.

People ask questions about black holes because it is very interesting. Black holes only suck at a certain distance, so if you do not pass this determined distance, nothing will happen to you.

Anyway, if you change the sun through a black hole, nothing happens. Only if you pass from a distance does gravity absorb you and you can not escape and you will die in a different way than you normally hear. First your body is stretched and compressed making a spaghetti.

The following video is about a NASA astrophysics and it is a supernova explosion.

Salar of Uyuni

The Salar of Uyuni is the biggest and widest salt desert in the world. It measures one thousand, five hundred and eighty-two square kilometers, and it is located in Bolivia. This work of the nature produces twenty-five thousand tons of salt and one hundred and fifty million tons of lithium in one year.

It is one of the greatest wonders of nature especially when it rains, when it transforms into a giant mirror. In the center, there is an island with plants and animals.

I have chosen this natural place because this work of nature is the one that I like the most because of all its characteristics.

The Plants

Plants are living beings just like animals, they have no movement.

Plants produce their own food through the process of photosynthesis. They capture the energy of sunlight through chlorophyll and convert carbon dioxide and water into sugars that they use as an energy source.

A plant is composed of four parts, which are:

The root: its function is to fix the plant. Through it the plants obtain nutrients from the soil.

The stem: is the one that gives support to the plant. Some stems are thin and flexible, others, like those of trees, are woody and hard.

The leaf: is the structure where photosynthesis and respiration takes place.

The flower is the reproductive organ. Inside it has all the organs it needs to make the fruit and the seed.

Plants have different types with different characteristics, these are:

Green plants like algae

Earth plants like moss.

Vascular plants such as ferns

Plants with seeds like conifers.

The vascular plants are called superior plants or cormófitas that comprise of the flora. Its main characteristic is that they present a real differentiation of tissues in root, stem, leaves, flowers....

The terrestrial plants are plants that are characterized by having a series of adaptations for life outside the water, and that are therefore responsible for the colonization of the earth by the plants.

Green plants as their name suggests are plants with a greenish color.
Seed plants are a group of plants comprising all vascular plant lineages that produce seeds.

Depression

Hi bloggers!

Here you have the video that we have prepared for our Researching Project about depression, and remember that this disease is very important nowadays.

The World Multiple Sclerosis Day

Hi bloggers!

The World Multiple Sclerosis Day is held the last Wednesday of May.

Multiple sclerosis is a chronic central nervous system disease. It is present throughout the world and it is one of the most common neurological disease among the population aged 20 to 30 years.

If you want to help people who have multiple sclerosis, you can participate in the Mulla’t campaign, in which you can donate money or participate in a number of activities to raise money for the foundation.

Don’t doubt and help, participate against the multiple sclerosis!!

Life in other Planets

Hello friends,

Today I will talk about a controversial topic. Is there life in other planets?? In my opinion, I think that if there's life on Earth, why not on other planets?

As some of us know, where it is more likely is in the red planet known as Mars, because there is not too far from the sun or very close, as our planet. This confirms that living things may be living there, things such as plants, animals and even beings older than us.

However, we cannot confirm this theory because we do not have enough technology to go to Mars.

We also have other planets like Saturn, Uranus or Neptune but as they are quite far from the sun is less likely for their characteristics.

Well guys, this is my idea about the space and its mysteries, I hope you liked it!

Heat in Natural Sciences

In Natural Sciences in the topic of heat, we have studied various concepts, from heat conversion to changes of state through to heat balance.

First we analysed how to convert heat among different measures of temperature, Celsius degrees, Pharenheit and Kelvin. Next we studied how at a molecular level, heat can affect an object to change its state. For example increased heat can make an object go from solid, to liquid, and later to gas. 

Heat gives energy to the molecules, so they change their structure, this can be seen as a change from solid to liquid and to gas. Studying heat balance, we have focused on how we can calculate the amount of heat entering and leaving a system.

Science

This term with second ESO we have been studying the topic of Diet and Health.

When looking at diet in science, the main aspects of our work have been focused  on the balanced diet and what it consists in. Within this,  we have studied how each component of a balanced diet helps the body. For example meat, fish and poultry contain high levels of protein helping our body to grow , while wheat, cereals and grains contain high levels of carbohydrates that provide energy for our bodies.

My English Experience in Natural Science

"Last Friday, 30^th January, I made a presentation in Natural Sciences in English for my 2^nd A class. It was very funny because now I know how teachers feel. At first, I was very nervous and I said to my teacher “No please, I will do it wrong, please I don’t want to do it”. But finally I was in front of the class and they were listening to me. I was scared when I started talking about the forces and how to calculate them, but while the time was going by I felt much better. My English wasn’t very good but people said to me that they understood it. My teacher congratulated me and I was happy with the result. Now I have less fear, I can talk in English!"

Tectonic plates and volcanoes

Do you think there is any relation between the situation of the volcanoes and the tectonic plates? Why? Give arguments to support your opinion.

“Yes, because we can see that the most part of the volcanoes are on the border of the tectonic plates.

There are also few volcanoes that are not on the border of the tectonic plates. This is because inside the Earth it is very hot and it warms the Earth’s crust. Through the Earth’s crust holes the lava goes out. This is what is called hot spot.”
