ENERGIES - Clean energy beginning with dirty water


A progress of 2013 in the solar energy of low cost, was a solar cell very small. This solar cell can produce energy  like a sheet of a tree, it can suppose a energy souce for emerging countries. This types of technologies not only will improve the quality of live of emerging countries or sites where there aren´t electricity, also, on the environment.This cell would be a hit because the price of oil is very high and consumers search accessible solutions.

UNIT 5 - PULLEY (EXERCISES)

It is form with a wheel that it has a central orifice that permit rotate fixed or freely on its axis,has got a channel in its periphery for can drag or be drag for one rope,chain,belt... There are different types of pulleys FIXED PULLEY:formula(F=R) MOVABLE PULLEY:formula(F=R/2) HERE WE HAVE SOME EXERCISE FOR PRACTISE THE PULLEYS.(interesting,and good for revise) http://www.educa2.madrid.org/web/educamadrid/principal/files/a1c18b06-dde8-4e44-98a0-49f0e0f2c425/M%c3%81QUINAS%20Y%20MECANISMOS/M%c3%a1quinas%20y%20mecanismos.pdf

ENERGIES - "Green toys" are trendy!


Spatial bases with solar panels, hydro-powered cars, doll houses with wind turbines and receivers to collect rainwaters are some of the "green toys" that are trendy.
Environmental toys promote that young children think about where energy came and how much can use, increasing their knowledge about renewable energies through the game. The manufacturers think that this toys will have an important role in our future.

UNIT 5 - RESOURCES

Some resources for review this unit:


Here you have an interesing game to know the use of the simple machines (inclined plane, level, wheels, pulley) This is a game of the museum of the Science of Chicago. Try to obtend the objects with simple machines!


- In this web, you can see a section of mechanisms and you can find a lot of webs, presentations, notes and animations for review this unit.

UNIT 5 - HOUSE OF MACHINES

This is a good example of connected mechanisms in which you can see a house of machines in which there are mechanims made with wood.

UNIT 5 - MACHINES

Machines are something that helps you use energy and more effectively.One of the simple machine is the inclined plane which allows you to trade increased distance for decreased effort or force:by doubling the distance you move a thing,you can half the force you need to exert.

UNIT 5 - "THE GREAT SEARCH"

Here we have a short video in which you can see the evolution of the technology with the use of the energy souces and simple machines. Hope you like it:)

ENERGIES - SOURCES OF ENERGY

The energy is the base for do all humans activities.Exist a big contrast in the nivel of the energy consummation that we relate with: Economic development and Conditions of the population's life The consummation of the countries measure with TEP:quanty of energy that content in one tonne of petrol,that it use as unit of meaasure and it is equal a 1'435 tonnes of coal. The energies of we consum are from different sources.In the XIX century->coal was converting in the most important but in the middle of XX century-> petrol is the most important. (From the petrol we obtent 39% From the coal we obtent 25% From the natural gass we obtent 24% From the nuclear centrals we obtent 7%) =95% 100-95=5% ARE RENOVABLE ENERGY (are dates of 2006 aprox)in the image are actual dates

OFF TOPIC - TECHNOLOGY

Is a group of technical  knowledge and used to create goods and services for society, also this the technological education that teaches us the most important technologies. The technology influences in the society and the economy. Over time the technology is progressing and forming new objects.



ENERGIES - RENEWABLE ENERGY

Is the energy that is produced by nature and probably won´t spend. Alternative energy is similar to renewable energy, that generate a few gases of greenhouse.


ENERGIES - Geothermal energy

Geothermal energy is the energy that can be obtained by harnessing the heat from inside the Earth.
This internal heat warms up the deeper water layers: the rise, the hot water or steam producing geysers or hot springs that are used for heating. 
Here I put a video that explains it very well

OFF TOPIC - NBA2k14 , In my opinion the best.


Few weeks ago I wanted to talk about this topic. Is one of our famous `off topic´.
 The NBA2k14 game.
I think that is the best basketball game ever. 
You can play with any team in the nba (as may be Chicago bulls, Miami heat, Angeles lakers, Okc thunder ..)
and with any player that you want (like Lebron James, Kevin Durant, Chris Paul, James Harden, Kobe bryant..)
And this year you also can play with european basketball teams.
The part of the game that I prefer is `My carreer´, where you can create a professional basketball player and play in the nba, where you start being a rookie and  you improve to become the best player in the NBA, even better than Lebron James.
Elsewhere in the game you can play alone as Lebron, and following the path that has to become the best player in the nba.
If you like this post please, tell me your favourite player and your favourite team of the nba , Thanks for reading.

ENERGIES - The hydraulic energy

Our energy, hydraulic energy consist in use the kinetic and potential energy of water to produce energy for people. Its advantages are that are a green energy because it doesn't pollute,  is much cheaper than oil.
Its disadvantages are that we need to flood large extensions of land , because we need water that moves  the turbines of the reservoirs to  produce the energy and with this action we lose a lot of ground that we use to build houses. The most important hydraulic energy its use in Brazil, Argentina,United States, China .
These are some of the main features of this energy that I wanted to explain. Soon my team will work on this energy with many more features. I think this is a good summary what do you think?

ENERGIES - CONCEPTS

Natural resources:are the element that the humans,with their technology,use in their profitul
  • Not renovable energy hen we spend quickier than it is produced.The time for renovable is long in this product and we should wait a long time for can spend and use.Ex:nuclear...
  • Renovable energy:it need a hort period for its recuperation.Ex.wind,sun
  • For can understand the energies you must know this conceps,there are very important and how you see also influences the technology.



    ENERGIES - OUR ENERGY,YOUR ENERGY

    For final of course we must do a presentation of one energy for know their uses,how they work and the main ideas.Our team must do a hydraulic energy and we are going to put in the blog interesting information,resources,games,activities,videos about it.Also we want know about the others energies and we want teach your some things.It is a proyect for final course that we are going to work a lot and see you.We must do some activities that you will see.The energy is a important thing in our life and we use all days,without them the life not be posible.

    UNIT 5 - Mechanisms

    Man builds objects for meet his needs and improve his quality of life. If you look around you, you can see that the majority of this objects have or produce some kind of movement with a purpose, like: clear the clothes, indicate the time, move people...

    Here we have the example of a coffee grinder. It has a  simple operation and it´s based on a lever on the top that turns gears of the machine and the grains of coffe become pulverized. The result is collected in a drawer and it´s ready for be taken in a cup of coffee.

    ENERGIES - Wind energy

    Wind power is the conversion of wind energy into a useful of energy such as using wing turbines to make electrical power.

    ENERGIES - SOLAR ENERGY!

    I think that the solar energy is radiation from the sun, it´s used by humans and it´s essential. Heat and light can be harnessed and converted into electrical and thermal energy. It´s a renewable energy. The solar panels are used to obtain energy.

    OFF TOPIC - ELECTRONIC APOCALYPSE



    Solar storms are produced by the magnetic activity when the sun is stronger, it happens each 11 years. This phenomena can produce in the Earth magnetic storms and affect to the satellite communications, navegation systems and electrical networks. The electronic apocalypse could be produced if there are a solar superstorm (which restricts these systems two years) and it can be worse than the strongest solar storm that ocurred because we have a lot of technological dependence.
