The nanotechnology is a new kind of science, I think that schools could give courses or classes to students and teachers to know more about this science.
Another thing is that enterprises use nanotechnology to innovate machines for example, to use this science to create better jobs.
In the technological world this is used to reduce the information, for example there is the iPod, this mp3 player use nanotechnology to comprime the information and you can introduce more music, video, pic's and all that you want.
It's very important for us to use nanotechnology, we need to investigate more, practice with them and use it for good reasons.
Students like me, have to compromise with teachers or instructors that give classes.
I think that nanotechnology could be used like a normal signature like maths, chemestry, to be introduced in school programs.
TEST OF NANOTECHNOLOGY
1.- Do you know what is Nanotechnology?
2.- Do you want to learn more about this theme?
3.- Do you use Nanotechnology in your life? One example.
4.- Do you know how the iPod is composed?
5.- Write 3 examples of products that you know Nanotechnology uses?
6.- Is it important to know what is Nanotechnology? Why?
7.- Do you agree that Nanotechnology be used in schools? Why?
8.- What things people would do with Nanotechnology?
9.- Do you belive Nanotechnology is used in the NASA? How?
10.- Give your opinion about Nanotechnology.

Summary (Nanotechnology)
Well hi teacher, in the pages that I've checked I found this information:
The first use of the distinguishing concepts in 'nanotechnology' (but predating use of that name) was in "There's Plenty of Room at the Bottom," a talk given by physicist Richard Feynman at an American Physical Society meeting at Caltech on December 29, 1959. The equivalence of one nanometer (nm) is one billionth, or 10-9 of a meter.
The Nanotechnology is used from many things, this science has a lot of fileds of study there are applied physics, materials science, interface and colloid science, device physics, supramolecular chemistry, chemical engineering, mechanical engineering, and electrical engineering.
Nanotechnology can be seen as an extension of existing sciences into the nanoscale, or as a recasting of existing sciences using a newer, more modern term. Two main approaches are used in nanotechnology. In the "bottom-up" approach, materials and devices are built from molecular components which assemble themselves chemically by principles of molecular recognition. In the "top-down" approach, nano-objects are constructed from larger entities without atomic-level control.
Examples of nanotechnology in modern use are the manufacture of polymers based on molecular structure, and the design of computer chips ayouts based on surface science. Despite the great promise of numerous nanotechnologies such as quantum dots and nanotubes, real commercial applications have mainly used the advantages of colloidal nanoparticles in bulk form, such as suntan lotion, cosmetics, protective coatings, drug delivery, and stain resistant clothing.
I hope that this information serve, well this is my summary.
Bye teacher, see you in the next class

Capabilities in the Field of Nanotechnology
The University of Surrey (UniS) pursues a clear mission to serve society by producing dedicated people with appropriate knowledge and skills as well as by providing imaginative and technologically informed solutions for industry, commerce and the professions.
The range of UniS’ expertise in the expanding field of nanotechnology is significant. The majority of the scientific and engineering capability for nanotechnology is within research groups and centres belonging to the Schools of Engineering, Biomedical and Molecular Sciences as well as Electronics and Physical Sciences. Societal, organisational, ethical, and risk perception issues are also dealt with within the School of Human Sciences and the European Institute of Health and Medical Sciences. The following tables provide a general, but not exhaustive, overview of capabilities.

Facts about Halloween
The origin of Halloween dates back at least 3,000 years to the Celtic celebration of Samhain (pronounced "sow-ain"). The festival was held starting at sundown on October 31st and lasted until sundown on November 1st. It was similar to the modern practice of the New Years celebration. On this magical night, glowing jack-o-lanterns, carved from turnips or gourds, were set on porches and in windows to welcome deceased loved ones, but also to act as protection against malevolent spirits. Burning lumps of coal were used inside as a source of light, later to be replaced by candles.Samhain was not the name of a "Lord of the Dead", no historical evidence has ever been found to back this up, it was simply the name of the festival and meant "Summer's End". It was believed that the souls of the dead were closest to this world and was the best time to contact them to say good bye or ask for assistance. It was also a celebration of the harvest. It is still treated as such today by those who practice Wicca or other nature based religions. It has absolutely nothing to do with satan, who was a creation of the Christian church.When European settlers, particularly the Irish, arrived in America they found the native pumpkin to be larger, easier to carve and seemed the perfect choice for jack-o-lanterns. Halloween didn't really catch on big in this country until the late 1800's and has been celebrated in many ways ever since!

Diego Hurtado: He read about oceans, the oceans are the base of Earth´s life, the article talks about animals and plants.
Ricardo Sandoval: He read a topic related about space, an international space station would be send. The countries that participate are: Russia, Japan, Brazil, USA, they would study biomedical projects.
