1.- TECHNOLOGY AND SCIENCE.
What´s technology?: Technology is the group of knowledge, skills, and techniques that human use to satisfy needs and to solve problems.
Techhnology is the practical application of knowledge. Technology works like a system that involves turning natural items into useful products: eg.car, tin, clothes, etc. It´s the “know-how”.
Technology works like a system (Input-Process-Output and feedback) where natural items turn into manufactured products. Systems are developed to address a goal.

• The INPUT are the resources availble to the system.
• The OUTPUT are the products generated by this system.
• The PROCESS is the way to get the goal.
• The FEEDBACK is used to control this process, it is the signal or measure that says how well the goal is being achieved, or how well the process is working.

2.- TECNOLOGY AND SOCIETY.
Technology and society work together: technology responds to society´s needs and helps societe to develop.
Nowdays technology is present in all areas of society and has made major changes to our lives. Can you image a world without telephones or computers? And without cars, trains or planes? Could we live with food that only comes from tradicional agricultural processes?

ACTIVITY Nº1:
1.1. Look for information about the main industries in your community. Write a short report about what is produced and how technology is used for.

1.2. Find out and write down the environmental problems that can come from those processes.

MARZIPAN
Marzipan is a confection consisting primarily of sugar or honey and almond meal, sometimes augmented with almond oil or extract. It is often made into sweets; common uses are marzipan-filled chocolate and small marzipan imitations of fruits and vegetables. It is also rolled into thin sheets and glazed for icing cakes, primarily birthday and wedding cakes and Christmas cakes. This use is particularly common in England, on large fruitcakes. Marzipan (or almond paste) may also be used as a cake ingredient, as in stollen. In some countries, it is shaped into small figures of animals as a traditional treat for New Year's Day. Marzipan is also used in Tortell, and in some versions of king cake eaten during the Carnival season. Traditional Swedish Princess Cake is typically covered with a layer of marzipan that has been tinted pale green.

PHOTO CAMERA

A camera is an optical instrument that records images that can be stored directly, transmitted to another location, or both. These images may be still photographs or moving images such as videos or movies. The term camera comes from the word camera obscura (Latin for "dark chamber"), an early mechanism for projecting images. The modern camera evolved from the camera obscura.

The first permanent photograph of a camera image was made in 1826 by Joseph Nicéphore Niépce using a sliding wooden box camera made by Charles and Vincent Chevalier in Paris. Niépce had been experimenting with ways to fix the images of a camera obscura since 1816. The photograph Niépce succeeded in creating shows the view from his window. It was made using an 8-hour exposure on pewter coated with bitumen. Niépce called his process "heliography".All the people have nowadays a digital camera, it is an instrumet that many people use when they go on holidays or when they go out anywhere.

I was born in 1971, so when I was a kid, people weren't using the internet but I had a computer in my house when I about 11 or 12 years old and my dad taught me some basic programming and I even created a program where I fooled one of my friends into thinking that we had entered into the computer record system at my school and he was getting a bad grade in social studies and I made it look like we had entered into the social studies records file and I changed his grade and he was very scared about this. He went home and told his dad and finally called me back later on that evening and said, "Hey, my dad said that you need a modem to break into another computer."
