1. Science and Technology
UNIT ONE, LESSON 1.3
BY MARGIELENE D. JUDAN

2. LESSON OUTLINE
Review: Pure and Applied Science
Applied Science or Technology
Some Products of Technology
Feature: Filipino Scientist of the Week!

3. REVIEW: Pure vs. Applied Science
Pure science addresses basic
questions.
Supports applied science.
Restricted to abstract or
theoretical concepts.
For knowledge and research
purposes.
Applied science solves specific
problems.
Suggests questions for pure
science.
Used in actual practice or to
solve practical problems.
For problem solving purposes.
Often referred to as
“technology”.

4. REVIEW: Examples of Pure Science
1. Scientists study human vision to learn how the eye works.
2. Students look through a microscope to see what’s inside a cell.
3. A biologist is experimenting on a plant’s reaction to lack of
sunlight.
4. Anatomy, Cell Biology, Botany, Physics, Chemistry, Earth Sciences
are all pure sciences.

5. REVIEW: Examples of Applied
Science
1. Scientists invent motion pictures, eye glasses, and contact lenses.
2. Pharmacologists make and manufacture drugs and medicines.
3. Engineers create bridges and tall buildings.
4. Medicine, Computer Science, Engineering, Robotics and
Technology are all applied sciences.

6. TECHNOLOGY
Common term for applied science.
The application of scientific knowledge
(pure science) for practical purposes
Uses concepts and ideas (pure science)
to develop products that assist people in
their daily lives
Aims to make living efficient
and easier

7. Your book is a
product of
technology!

8. Without technology,
you would have to
write all these things
by hand.
That’s why books back
then were expensive
because it takes a lot of
effort to finish them.

9. You owe your
thanks to
technology! It
aims to make
your life easier.

10. SOME PRODUCTS OF
TECHNOLOGY
LASER
CT and MRI Scanners
Information and
Communication
Technology (ICT)

11. LASER
Acronym; Light
Amplification by
Stimulated
Emission of
Radiation

12. LASER (Uses)
Medical scalpel
Entertainment
Computers and
music (CDs and
DVDs)
Cutting metal

13. CT, MRI, PET Scanners
CT or CAT- Computerized
Axial Tomography
MRI- Magnetic
Resonance Imaging
PET- Positron Emission
Tomography

14. CT, MRI, PET Scanners (Uses)
Produces images inside
the body
Detects disorders of
tissues
Images are processed by
computers

15. CT, MRI, PET Scanners (Imaging
Methods)
CT or CAT uses a type of
X-ray device
MRI and PET uses the
magnetic properties of
substances in the body

16. Information and Communication
Technology [ICT] (Uses)
Sending messages
Internet
Satellite communication
TV’s and radios

17. Selective Breeding (Uses)
Applies genetic principles (pure science) to:
1. Increase yields of crops
2. Develop crops resistant to diseases
3. Enhance the nutritional value of food
4. Improve traits and characteristics of an
organism

18. Selective Breeding (Product)
GMO or Genetically
Modified Organism.

19. Food Preservation (Uses)
Promotes lesser
loss of food from
spoilage
Increases shelf
life of food

26. Activity Time!

27. Divide the class into two groups. The class will have a
debate tomorrow whether the effects of science and
technology on society are of more good or bad.
Use strong arguments to support your claim. Make a
research on your topic.
Group Task
