“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
Science concept…?
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?

PRESENT? CENTURIES AGO?
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.
1. Science as a Way of ThinkingEmpirical Basis of Modern Science
(present) vs. Authoritarianism (before 1660’s)
Aim for Objectivity; but still with Subjectivity
AssumptionsUse of Inductive & Deductive
Reasoning
2. Science as a Way of Investigating
Use of Scientific Method
The importance of Questions in Investigations
Testing by Additional ObservationTesting Hypothesis through
Experimentation
3. Science as a Body of Established KnowledgeConcepts, Principles and Laws
Use of Models in ScienceScientific Hypothesis & TheoriesDynamic Nature of Science
Usefulness of ScienceRemove fear of the unknownMake better materials (food,
infrastructures…)Make task easier and fasterPurify food and waterCure disease / delay death
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)?
“Science eliminates the worthless and the useless and then makes use of it in something else.”
-Thomas A. Edison
