1.

Differentiate science from technology.

2.

Are the processes of scientific investigation similar to technological design?

3.

Cite a technological innovation on invention /product and evaluate it on the basis of:

a)

Cost

b)

Efficiency

c)

Materials

4.

Illustrate the harms and benefits of technology.

ANSWERS:

1.

1. Science can be called a systematic knowledge base developed through observation and
experiment of the

structure

and behavior of the physical and natural world;

Technology

is the
application of scientific knowledge for practical purposes.


2.

No, because
the design process is a linear sequence of events that has a start and an end
point. (Sometimes you have to go back a stage if new inform
ation comes to light. In certain cases
you may only look at one or two stages).

Design is a problem solving activity that requires the
precise definition of the problem at the start.

Design is concerned with decisions of taste, choice
and sensitivity and r
elies on your value judgments. In Science you must not make value
judgments, you must report what happens.



3.


a.

It

depends

on

the

brand.

And

its

probably

more

expensive

if

it’s

the

latest

model.

b.

Everyone wants his or her computer to be efficient. P
eople don’t buy computers in the hope
that they will run slowly, freeze up, and generally cause problems. They buy computers with the
expectation that they’re going to be able to do a lot with their new machine, and that they won’t
have to wait forever for

boot up, downloads, or other things. All computers can experience
problems sometimes, of course, because that’s just the nature of electronics. These problems
should be few and far between, and you can help them stay that way by keeping your computer
runn
ing efficiently.

c.

There is a lot of plastic in
computers that

is what makes up the outer shell. the circuits and
transistors are mainly made of silicon.
The

transistors and wires are soldered together with a
variety of elements, such as tin, zinc, or copper.

Liquid cooling systems

are mainly water based,
but could be oil based, depending on the system
.

4.

Overall technology helps us more than it harms us. Tha
t's why life expectancy keeps going up
with technology. And it's not just a
correlation

either;

a cause and effect relationship can easily be
shown to exists. But I think, I think it makes us lazy in some ways.
