Como parte de las actividades y del programa de nuestro colegio, estamos estudiando el calentamiento global y algunos problemas que se relacionan.

Utilizamos el Facebook como medio de publicación, para darles a conocer a nuestros compañeros información que estamos aprendiendo y que queremos compartir.

Sabemos que a través de esta comunicación, estamos aprendiendo a redactar, a publicar y a dar retroalimentación.  Sabemos que las redes sociales nos ayudan a aprender, y el utilizar estos medios hace que nuestro aprendizaje salga del salón de clases para convertirlo en saberes para toda la vida.


About energy:
1:The energy than is obtain by the sun is called solar energy and it's very useful
2:The wind energy can be obtained in any moment in were the wind are very strong
3: the photosynthesis is the process in where we get energy of the plants
4:The water when was moving it produce a energy and that's the form of we get energy of the water

Global warming
The global warming in Mexico are very dangerous and have to many consequence like:there's more hot in Mexico,there's water shortage, and the level of the water of the ocean grow.


About energy
The Sun produce solar energy. the solar energy is received by solar pannels and it becomes in electricity.
If we use windmils the air becomes in electricity.
There is a lamp that their energy is produced by plants.
The water produce an energy that is called hydro power.

Global warming in Mexico.
The global warming in Mexico is very high, there are very hot places in Mexico because the global warming is affecting these country and others. The global warming is caused because many people pollute the world.


Global warming
Global warming is affecting all the planet... If we were talking about Mexico, I can say that temperature is changing a lot, Mexico is hot... Now imagine without the ozone layer... Is hotter! People living in Mexico is getting sick because of this problem. Your skin can burn and maybe that can cause a problem of Cancer, if you are changing of temperature quickly maybe you can get sick of your nose etc.! Take care of the planet!

Renewable energy is energy that comes from resources which are continually replenished such as sunlight, wind, rain, tides, waves and geothermal heat.
Solar energy applies energy from the sun in the form of solar radiation for heat or to generate electricity.
Geothermal energy is from thermal energy generated and stored in the Earth. Thermal energy is the energy that determines the temperature of matter.
Airflows can be used to run wind turbines. Modern utility-scale wind turbines range from around 600 kW to 5 MW of rated power.


Global Warming
Global warming is a very severe problem that affects all the countries throughout the world. In Mexico, climate is changing because of global warming. Climate in all the country is getting hotter reaching very high temperature for the people that are living here.

Energy Resources
The Sun produce solar energy, with the use of solar panels this energy can be converted in electrical energy.
With the use of windmills, wind can also be converted in electrical energy.
Water produce hydropower that can be harnessed for some useful purposes, for example, for the use of watermills or sawmills.


Kinds of Energy

Mechanical Energy is the energy of motion that does the work like the wind turns a windmill.

Heat Energy where motion or rise in temperature is caused by heat like a fire in your fireplace.

Solar energy is where natural energy that comes from Sun can turn to electrical energy by solar panels.


México affect the ozon layer because a lot of persons in Mexico didn't put the trash in the correct place so they pollute.
The sun give su energy with the solar panels .

You can use the air and wind turbines to have energy .
Some ingeniers want to do a machine of cars that get the energy of the water and not of the oil.

Global Warming
The global warming affects the planet because the people contaminate the sidewalks is very affected in Mexico because we pollute all,the temperatures are changed in poles and this temperature is very high.

Energy Recources
The sun give us the solar energy,to have this solar energy we have to use special things like the solar panel.
The wind is the second resource that we can use,we can use the wind turbines
The water is the last resource that we can use,we can use biopolymer,textil mills.

Global warming.
Global warming affects the ozone layer in all the world but one of the most affected countries is mexico,the temperatures have changed now all the year we have high temperature and we have to use sun protector for don't get too hot .

Energy produced by....
The sun.
the sun pimarly produce light so it can produce electric light by the solar pannels .
the hidráulic energy can be used by the forcé of the wáter.
the eolic energy is created basicly by the forcé of the wind and it can make factories work.

Global warming 
The global warming problem refers to the accumulation of gases in the Earth’s atmosphere.
Energy Resources
Renewable energy resources, such as wind, solar and hydropower, offer clean alternatives to fossil fuels. They produce little or no pollution or greenhouse gases, and they will never run out.

Problems of Global Warming in Mexico
One problem is that the wheather is changing because we contaminate the air using cars and if the wheather change it can produce droughts.

Problems of Global Warming in Mexico 
The problems are thant in Mexico now a days the wheather is very hot and some people burn and other is that many things with water are dry.

Energy Resources 
The Sun can gave us solar energy, to have solar energy you have to use special things like a solar panel.
The wind is another resource, to obtain the energy you have to use a mill.
The wáter is a resource where you can obtain Hydropower, this energy can be use to make watermills, sawmills, textile mills, power houses and paint making.



Nuclear energy usually means the part of the energy of an atomic nucleus, which can be released by fusion or fission or radioactive decay
That we are not using petrol, gas etc. and it's better for the world
That it pollutes... Not so much as petrol but it also pollutes 
My opinion: Maybe we can change our fuel for this one so we can recycle and not polluting(:

Nclear Energy

The sun and stars are seemingly inexhaustible sources of energy. That energy is the result of nuclear reactions, in which matter is converted to energy. We have been able to harness that mechanism and regularly use it to generate power. Presently, nuclear energy provides for approximately 16% of the world's electricity. Unlike the stars, the nuclear reactors that we have today work on the principle of nuclear fission. Scientists are working like madmen to make fusion reactors which have the potential of providing more energy with fewer disadvantages than fission reactors.

I think the nuclear energy is important because probably in the future we need thig types of enrgy.


  1. One of the most significant benefits of nuclear energy is that nuclear plants would produce energy even after coal and oil become scarce. Earth has limited supply of coal and oil. Thus, nuclear plants play a major role of in energy production.

    The major disadvantage of nuclear energy is the expulsion of radiation. These radiations are very harmful for the body, damaging the cells of the body. It not only makes people sick, but even causes death.


  2. Advantages and disadvantages of nuclear energy
    Nuclear plants bring jobs and prosperity to a town or country
    Provides the world with most of its electricity
    Its good for the econmy

    Nuclear energy produces radiation
    Nuclear power plants are very expensive to build
    Uranium is not renewable and can lead to environmental problems


  3. enefits & damages of nuclear energy


    Although the production cost is lower compared to other energy sources, the construction of new reactors, startup operations, waste dispocion investments represent very high.


    Electric power generation through nuclear plants produces no carbon dioxide

  4. Benefits and damages of nuclear energy.

    Nuclear power plants produce no controlled air pollutants, such as sulfur and particulates, or greenhouse gases. The use of nuclear energy in place of other energy sources helps to keep the air clean, preserve the Earth's climate, avoid ground-level ozone formation and prevent acid rain.
    The principal risks associated with nuclear power arise from health effects of radiation. This radiation consists of subatomic particles traveling at or near the velocity of light---186,000 miles per second. They can penetrate deep inside the human body where they can damage biological cells and thereby initiate a cancer. If they strike sex cells, they can cause genetic diseases in progeny.
