needs? Discuss and answer the questions.

needs.

WHAT IS TECHNOLOGY?
Technology
produces
objects
and develops
systems
or strategies that solve
problems and
satisfy
1
our needs from the simplest to the most sophisticated.
An object can be a tool, machine or household appliance. A
system
2
can be the
way a train station is managed or the way someone who is hurt on a mountain is
rescued.
Sometimes the process of resolving the problem is very simple and generally
consists of various stages in which one or more people are involved.
The steps are based on a logical series of operations that start with the detection
of the need and end with checking the efficiency of the object or system that
resolves the problem.
Here is a possible sequence in the technological process:
Need
Idea Development of the idea
Construction
Verification
3
Need
Analysis of the need or problem and the conditioning factors.
Study of previous cases and their solutions.
Idea
Propose one or various solutions.
Agree on and choose the best solution.
Development of
the idea
Tools, materials and labour needed.
Prepare a budget.
Construct
Construction and testing.
Verification
Evaluate.
Write a final report.
Understand
1.
Look at the photo and
discuss the questions.
a)
What is this object for?
b)
How did we satisfy the
same needs before it
existed?
Discuss and write.
Technology
is the practical application of knowledge (science) and skills
(technology) to create a solution (an object or a technological system) that
allows human beings to satisfy their needs or problems.
The
technological process
consists of a series of stages that lead to the
efficient solution to a problem or need.
1
satisfy
:
provide something we need
2
system
: a combination of thingsworking
together with a common function
3
verification
:
evaluation and checking
that something satisfies the proposed
requirements stated at the beginning
of the process
