2. What is Technology?

3.  Learning new facts

4.  Solving problems
?
Asking question collecting information finding answer

5.  Inventing new things

6.  It is the innovation, change, or modification
of the natural environment in order to satisfy
perceived human wants and needs.
 The goal of technology is to make
modifications in the world to meet human
needs.
 Technology is the process by which humans
modify nature to meet their needs and
wants.

7.  Deals with the natural
world.
 Is very concerned with what
is (exists) in the natural
world. (i.e.: Biology,
Chemistry, Physics,
Astronomy, Geology, etc.)
 Deals with how humans modify,
change, alter, or control the
natural world.
 Is very concerned with what
can or should be designed,
made, or developed from
natural world materials and
substances to satisfy human
needs and wants

8.  Is concerned with
processes that seek out
the meaning of the
natural world by
“inquiry”,
“discovering what
is”, “exploring”, and
using “the Scientific
Method”.
 Is concerned with such
processes that we use to
alter/change the natural
world such as
“Invention”,
Innovation”,
Practical Problem
Solving, and Design.

9. Technology is not any more “applied science” than science is
“applied technology”.

10. The power and promise of
technology can be further
enhanced through the study
of technology to assure that
all people are technologically
literate in the future.

11.  Biology
- is the study of living things. A scientist who is
an expert in the study of biology is called a
biologist

12.  Botany
- is the study of plants. A scientist who is an expert in
the study of botany is called botanist

13.  Zoology
- is the study of animals. A scientist who is an
expert in the study of animals is called a
zoologist

15.  Chemistry
- is the science of the composition structure,
properties, and reaction of matter. A scientist
who is an expert in the study of chemistry is
called chemist

16.  Physics
- is the science of matter and energy and the
interaction between them. An expert in the
study of physics is called a physicist

17.  Ecology
- is the study of how organisms interact with
each other. An expert in the study of ecology
is called ecologist

18.  Geology
- is the study of the structure of the earth’s
surface. An expert in the study of geology is
called geologist

19.  Meteorology
- is the study of weather and climate. An
expert in the field of meteorology is called
meteorologist

20.  Astronomy
- is the study of the heavenly bodies . A scientist
who is an expert in the study of astronomy is
called astronomer.

21.  Taxonomy
- is the study of classification of plants and
animals. An expert in the field of taxonomy is
called taxonomist.

22. The Scientist
o Louis Pasteur
- a French
scientist who is
famous for
working on
fermentation
and decay,
pasteurization

23. The Scientist
o Dorothy Hodgkin
- a British who was
awarded a Nobel Prize in
chemistry in 1964.
- she determined the
structure of biochemical
compounds essential in
fighting pernicious
anemia

24. The Scientist
o Arturo Alcalaz
- considered as the “Father of
philippine Geothermal Energy
Development”
- he is credited for making the
Philippines the world’s
second largest producer of
geothermal energy
- won the Magsaysay Award in
1982

25. The Scientist
o Dr. Luis Ma. Guerero
- a bacteriologist , peditrician
and renowned medical
specialist
- first physicians to become
a specialist in this field
- his contribution to the
knowledge of beriberi and
leprosy led the prevention of
death caused this disease in
both infants and adults

27.  Observing
- we need to observe very well to know the
characteristics and properties of things. We
use our senses

28.  Describing
• Telling about the features of the object being
observed ( color, shape, size, and texture )

29.  Comparing
- telling their similarities or differences

30.  Classifying
- grouping objects according to their
common characteristics or properties

31.  Measuring
- using some measuring tools such as thermometer= used to measure
temperature( measured in units called degrees)
- use ruler, meterstick or a tape measure to measure length ( express
in units called meter)
- use weighing scale , platform balance or spring balance to measure
the mass of an objects ( gram and kilogram are used to measure the
mass)
- stopwatch or clock is use to express time

32.  Making Inferences
-making good and accurate observation or
making an explanation

33. Science Laboratory Tools
• Microscope – is an optical instrument that
enlarges images of very small objects that
cannot be seen by the eyes.

34. Science Laboratory Tools
• Magnifying glass – is an instrument used for
observing tiny objects

35. Science Laboratory Tools
• Test tube – is used for heating small amounts
of liquid

36. Science Laboratory Tools
• Test tube holder – is a metallic device used to
hold a test tube

37. Science Laboratory Tools
• Graduated cylinder – is used for measuring
volume of liquids like water, oil, and other
solutions

38. Science Laboratory Tools
• Alcohol lamp – is used for heating materials

39. Science Laboratory Tools
• Evaporating dish – is a porcelain dish used in
evaporating a chemical solution

40. Science Laboratory Tools
• Beaker – is a thin glass vessel used as
container for fluids, it has graduation or masks
for the measurement of volume

41. Science Laboratory Tools
• Thermometer – is used for measuring
temperature

42. Science Laboratory Tools
• Funnel – is a device used when pouring liquids
or fine particles to a small-mouthed container

43. Science Laboratory Tools
Extra care must be observed when using
laboratory tools and materials .Always clean
and keep them properly after use.
