Technological Process
What is technology?
Technology is the practical application of knowledge (science) and skills
(techniques to create solutions (technological objects or systems) which
satisfy our needs or solve our problems.
process of planning
The solution then becomes the technique for future technological
problems we can use the technique again. This is how technology
develops We build on previous mventions. 'I'his is called technological
evolution or development.
Summarise and analyse the background
• Find information about previous solutions to this type of
topic subject problem
• Consider technical aspects that could affect the protect. (Use
connected to the topic books, catalogues, the Internet, etc.l.
• Classify and select the data that is most useful.
• Ord r this mformation svstematically in topics
• Make a note of relevant practical details related to the data.
Examples of mformation needed
• What types of nest are theres
• Which is most appropriate for the species
in our garden
• What materials are normally used by
the birds?
• What appropnate materials have we got?
platform in storks• Where can we build the nests
• How can we fix it?
wicker nest to tansies wicker nest wooden bird house
Using information about similar cases you can find vanous solutions
You can use the solution most similar to your case as a model and adapt
it to your needs you can also combine various suggestions and create a
new solution.
~ Design an individual idea
After you have found and analysed all the information you can start
to design:
• Use exist mg models and draw possible vanations to adapt them to
your needs
• Explore the possibility of using new materials.
• Introduce minor modifications or combine models you find
interesting.
These drawings should clearly show people your ideas
Agree and choose the best solution
Sometimes we like our own design, sometimes we prefer our cost: the money needed

You can create a table to help choose the best design For example,
to look at
this table has five categones We can give points ie.g, out of 10 .The design with the most points is
the one you choose
classmate's design. How do we choose? To produce a product
Construct the design
• Before constructing the object, decide how to make each piece
• If something appears difficult to do, find that solution first. The
problem may be more difficult to solve later.
• Drawing is the first step to building.
• Draw the pieces in the order you are going to make them
• Decide how to join the next piece before you draw it.
Prepare an estimate

The types of drawings we can use are:
• Views of the complete object: these give us an idea about what
the final proyect will look like and how it will work.
• Overhead view, side view and front view: we use these views to
give technical details of the size and exact shape of the pieces We
write the measurements of the pieces on these drawings
• Details of the way pieces are joined: to solve technical problems
We use an appropiate scale and draw them in perspective.
• Separate pieces: these are views of each piece that makes up the
whole object .These drawings define exactly what we need.
To make an estimate of the construction costs in advance, then you will
know whether rhe proiect is worthwhile.
To make an estimate, you need to know the price and quantities of
the materials you are going to use.
The price can be expressed according to different measurements
unit, surface, weight, length, etc .Use the appropiate measurement to
calculate the price. In this example plywood is measured in number of
sheets.
Construct and test
lt is easy to make an object if the process is planned correctly. If you have a good design and plan correctly, construction will be quicker and more efficient.
Normally, you should make the biggest pieces first. These form the base of the design.
Evaluate and check
Evaluauon is a cntical analysis of the final product to help improve it.
Construction report
Using all the documents wntten during the construction process,
write a report on the construction of the object.
Organisation of workshop activities

• The coordinator is responsable for organising the work of each
group member to achieve efficient teamwork .This person
represents the group
• The person responsable for the material collects the material
needed for the work and is also in charge of recychng leftover
material
• The person responsable for the tools looks after the tools
assigned to the group to make sure they are not lost
or damaged
• The secretary collect, checks and organises all the written
documents trorn each group member (plans, process reports,
estimates, etc.)
• The person responsable for health and safety makes sure
that the group members follow the health and safety rules in the
workshop and when using tools
• The person in charge of cleaning makes sure each workstation
Technology, society and the environment

Until the Industrial Revolution (in the 19th century), technology was
based on experience and perfectmg techniques that had existed
ancient times. Technology developed very slowly for centuries.
when the Industnal Revolution took place, scientific research something
became more important, this research affected techno(osteal
processes. Scientific laws there used to increase production and
machines were invented to do certain jobs. This meant that millions of
people no longer had to do laborious work. Productivity and standards
of living increased.
Technology and society work together: technology responds to
society's needs and helps somety to develop
Sustainable development

Of course, technological development has many advantages, but it
also creates a series of problems
• Resources (animal, mmeral or vegetable) are overexploited
they can run out and natural habitats disappear
• Polluting gases are produced
• Toxic waste is produced
