Introduction to Science and Technology for Grade 7

1. Nature of
ScienceMs. Maria Glofelsa O. Quiambao

2. “Science is built up with
facts, as a house is with
stones. But a collection
of facts is no more a
science than a heap of
stones is a house.”
Henri Poincaré

3. Science
concept…?

6. Our search towards the truth…
What comes into mind when we hear the
word SCIENCE?
When you were younger, why were you
asking your parents a lot of questions? What
are these questions?
How is Science related to technology?
Why… oh WHY do I have to learn these
things?!

7. SCIENCE TECHNOLOGY
Latin word: ‘scire’
meaning to know.
Study of the natural
world.
Describes nature
through laws &
theories obtained
through systematic
analysis of
phenomena.
Application of
scientific principles in
industry, commerce,
education and the arts.
Uses knowledge for
solving problems

8. SCIENCE TECHNOLOGY
Principles in chemistry Making perfume…
Principles in physics Making bridges…
Principles in biology Better-yielding
fruit trees…

9. Where would you rather live?
PRESENT? CENTURIES AGO?

10. Science should be viewed as…
1) a way of thinking in the pursuit of
understanding nature.
2) a way of investigating by which
hypothesis are tested.
3) a body of established knowledge of
which truthfulness may be questioned.

11. 1. Science as a Way of Thinking
Empirical Basis of Modern Science (present)
vs. Authoritarianism (before 1660’s)
Aim for Objectivity; but still with Subjectivity
Assumptions
Use of Inductive & Deductive
Reasoning

12. 2. Science as a Way of Investigating
Use of Scientific Method
The importance of Questions in Investigations
Testing by Additional Observation
Testing Hypothesis through
Experimentation

13. 3. Science as a Body of
Established Knowledge
Concepts, Principles and Laws
Use of Models in Science
Scientific Hypothesis & Theories
Dynamic Nature of Science

14. Usefulness of Science
Remove fear of the unknown
Make better materials (food, infrastructures…)
Make task easier and faster
Purify food and water
Cure disease / delay death

16. Position paper: (due on Monday)
 Research for the truth in the following trivia and
answer the question that follows. Write your answers
on a whole sheet of paper with proper penmanship and
reference.
TRIVIA: The Romans, more than two thousand years
ago, built bridges that made use of designs that are
scientifically sound. Several of these structures stand
until now.
QUESTION:
Which then came first, SCIENCE (the study of nature) or
TECHNOLOGY (the application of Science)?

17. “Science eliminates the worthless
and the useless and then makes use
of it in something else.”
-Thomas A. Edison
