TECHNOLOGICAL PROCESS
1. DEFINITION OF TECHNOLOGY
Techniques
Science
skills
As you have noticed, the workshop is a completely different classroom to the others in the high school in which there are some specific areas where everything is organised. This picture shows these areas and the stuff they store.

2. TECHNOLOGICAL PROCESS STAGES. Every time it is required to find a technological solution we must follow a set of stages (phases / steps / periods):

4. How is distributed the workshop?
Technology is the coordinated application of SKILLS (Techniques) and KNOWLEDGE (Science) in order to create a SOLUTION (Technological object or system) which satisfy our NEEDS or solve our PROBLEMS

2. IDEA 1. NEED 3. DEVELOP THE IDEA
As it happens in all companies and factories, the activities carried out in a workshop must be organised. That’s why each member in a workshop group has a role:
The coordinator organises all the work among the group members and represents the group.
The
secretary collets, organises and checks all the written documents from each group member. (Plans, quotations, notes, process reports…)

What does Technology depend on?
The one responsible for the materials collets the materials needed the group to make sure they are not lost or damaged.
The one responsible for health and safety
makes sure that the group members follow the health and safety rules in the workshop and when using tools.
The one in charge of cleaning makes sure each workstation is left

6. Are there any rules to follow in a workshop? Types of signs Of course there are many rules which are classified into 2 big groups:
Health rules: Their aim is to enable workers to undertake their occupation in good environmental conditions, causing the least harm to their health
Safety rules: Their aim is to prevent accidents and reduce the risk of hurting ourselves.
In a workshop, there are tools and machines which can be dangerous if they are not used properly, so that's why everyone must follow some compulsory advice and instructions.
Health rules
Safety rules
UNIT 1.- technological process
As soon as you have any kind of accident (cuts, burns, and dust in your eyes…) tell your teacher immediately. Keep your hands dry and clean. Keep your workstation and the workshop clean and tidy while you work and every time you finish a task. Put your tools away when you are not using them. Try to work being quiet (quietly) so that too much noise makes people irritable and aggressive and interrupts concentration.
Mandatory signs
Danger signs
They inform about the obligatory protections that you have to wear to avoid accidents.
General mandatory action sign
Wear protective clothing
Wear ear protections
Wear head protections
Don’t wear necklaces, rings or loose-fitting clothes. They may get caught in the machines. Ask everything you don’t understand on how to use machines and tools after reading the instructions and features. Don’t use any of them if you don’t know how to use. Use the right one for the right task. Make sure they are in perfect condition before you use them (check there aren’t parts missing or broken, the handles are secure and safety elements are in place. Don’t waste materials and look after your equipment. Find out where everything is in the workshop (alarm bells, fire extinguishers, signs, equipment…) Obey signs (Mandatory, danger, first aid and emergency and prohibition.
Wear eye protections
Wear a mask

7. Technology, society and the environment
9. The market (advertising & comsumption)
Until the industrial revolution (in 19th century) technology was based on experience and perfecting techniques so that technology was developed very slowly for centuries.
We all usually buy things when we need to satisfy a need or solve our problems (Remember the purpose of technology) but… Have you ever thought what happens in that moment? Well in one hand, companies provide goods to meet consumer demand and, of course, they obtain a profit since companies sell them at higher price than their manufacturing cost. In the other hand the consumer can’t avoid (help) buying these goods:

When industrial revolution took place scientific research become more important, affecting the technological processes. This situation made to increase production and machines were invented to do certain jobs allowing that millions of people no longer had to do laborious work. Productivity and standards of living increased.
Because they are normal or necessary goods like basic foods (bread, milk…) Because they have been exposed to aggressive advertising campaigns and consumers buy stuff they don’t need and sometimes pay inflated prices for them. As for advertising can influence us, it’s really important to be critical when we face with pressure from advertising.
Technology responds to society’s needs and helps society to develop. Although technological development has many advantages, it also creates serious PROBLEMS IN THE ENVIRONMENT such as:
Exhausting
of natural resources and raw material. Resources overexploitation (animal, mineral or vegetal). They can run out and habitats disappear.
UNIT 1.-technological process
Pollution. Human activities generate substances that impact on the
environment and can damage to living organisms, people, animals, vegetation, lakes and rivers.
Social inequalities between countries and regions.

Nowadays, the most important technological issues related to the environment are:
Technology has to optimise materials and time Technology has to find a sustainable development
without
damaging the environment.
8. The company (business activities) All companies produce goods (products or services) that improve our standard of living. They all carry out procedures which organise their work in an efficient and effective way. The main activities in a company are classified into:
Management
Objectives’ Establishment Making decisions
Production
Manufacturing goods Production process Quality control
Distribution
Sales teams Transport networks Advertising campaigns Post-sales service
Logistics
Activities to support the company Market research Finance

10. Analysis of a technological object When we need to know how an object is made of, its features and understanding how it works, it is required to answer several questions so that’s why we organise this procedure by analysing:
Its form (Analysis of form) Its technical composition (Technical analysis) Its function (Analysis of function) Its socio-economic impact. (Socio-Economic analysis) Analysis of form
Analysis of function
This analysis describes the shape of the object and it comprises these tasks:
This analysis describes the object’s use and it comprises these tasks:
UNIT 1.- technological process
1. 2. 3. 4.
Draw the object What shape is it? (Sphere, a cone, a prism…) What are its exterior measurements? (height, width and depth) Draw each of the separate pieces of the object
Images licenses http://www.freepik.es/vector-gratis/vectores-de-ultiles-escolares_740864.htm
Technical Analysis This analysis describes the manufacture of the object and it comprises these tasks:
1. 2.
How many pieces make up the object?
3. 4. 5. 6.
How are the pieces joined?
What material is each piece made of? (wood, metal, plastic, textile, stone…) What are the physical principles that make it function? What manufacturing process has been used? Which dimensions should be standardised?
1. 2. 3. 4. 5. 6. 7. 8.
What is this object used for? What are its different pieces for? How does it work? What are the instructions for use? What problems can occur when it’s being installed? What kind of maintenance does it require? What safety risks are there in using the object? What other objects have a similar function?

Socio-economic Analysis This analysis describes the social function and economic and environmental repercussions of the object and it comprises these tasks:
1. 2. 3. 4. 5. 6.
What is the origin of the object and what need does it satisfy?
7.
Could this object be made from cheaper materials? Explain your answer
Did we use anything different in the past? What are the environmental effects of its use? How is this product sold? How much does it cost in the shops? Is it expensive or cheap relative to other objects with the same function?
