Science
What is Science?
An attempt to
discover order in nature and use
that knowledge to make prediction
about what is likely to happen in
nature.
What Scientists DO???
Types of Reasoning Scientists Use
Inductive Reasoning
Involves using specific
observations and measurements to arrive at a general observation and measurements to arrive at a general conclusion or hypothesis.
Deductive Reasoning
Involve using logic to arrive at a specific conclusion on a
generalization of premise.
Example of Experiment:
Inductive Reasoning (1)
• You walk into your bedroom at night and flick on the light switch.The light does not come on.
Observation
• Why did the light not come on?
Question
• Maybe the power for the house is out
Hypothesis
Example of Experiment:
Inductive Reasoning (2)
• If the power is out, the lights in
other rooms should also be out.
Test of Hypothesis
• To check this prediction, go to other rooms and click light switches.
Experiment
• Lights in other rooms come on when their switches are clicked.
Results
• Power to whole house is not out.
Conclusion
Example of Experiment:
Deductive Reasoning (1)
• Mimicry of certain fly species (prey) to imitate jumping spiders (predator)
Phenomenon
• Jumping spiders wave their legs in the presence of potential competitors
• Certain fly species, when approached by jumping spiders, wave their wings which have markings that resemble spider legs
Observations
• What is the
function of the flies’
wing
markings and
waving behavior?
Question
• The
markings and wing waving increase survival of the flies by causing jumping spiders to flee
Hypothesis
Example of Experiment:
Deductive Reasoning (2)
• That the hypothesis is correct
Prediction
• The flies wing
markings are
masked with a dye
Experiment
• Then jumping spiders should pounce on the
experimental flies more often than they do on control flies with normal wing
Predicted
• Conclusion Is the
hypothesis about the wing
markings correct?
Conclusion
Example of Experiment:
Deductive Reasoning (3)
Hierarchy of Scientific Confidence
Scientific Law/PrincipleScientific Theory
Experiment
Hypothesis
Tentative explanation a scientist proposes for a specific phenomenon that has been observed
Designed to test the hypothesis
- Hypothesis fail the test rejected
- Hypothesis survived the test accepted
Scientific Law/Principle
Scientific Theory
Experiment
When a hypothesis has been tested over and over again and has not been contradicted
- E = MC²
- Law of Thermodynamics
Hierarchy of Scientific Confidence
Synthesis of a large body of information that
encompasses well-tested and verified hypotheses about certain aspect of the natural world.
Evolves in redefinition and refinement.
- Evolution Theory
SYSTEM THINKING
What is Systems Thinking?
Scientific field of knowledge for understanding change and complexity through the study of dynamic cause and effect over time.
As paradigm, it’s a way of thinking about the world and relationship.

Principles in Systems Thinking
•The art of seeing the forest and the trees; the whole is more than the sum of its part. Any problem is related to the larger forces and interactions.
Big Picture
• While habitual short-term fixes can impede long-term outcomes, one cannot ignore necessary short-term measures.
Short and Long Term
• There is more to a system than can be measured by conventional performance indicators, known as Key Performance Indicator (KPI), Critical Success Factor (CSF), Balanced Score Card (BSC).
Soft Indicators
• A great deal of problems encountered by organizations are created internally.
• We contribute to our own problems not only because of the unintended consequences but also because of our mental models.
System as a Cause
• Cause and effect are often not close in time and space.
• Time delays and chain effects of actions often mask the connection between cause and effect.
Time and Space
• Common confussion between cause and symptom of problem leads to inappropriate treatment.
Cause vs.
Symptom
Systems vs. Linear Thinking
Systems Thinking ≠ Conventional Linear Thinking
System thinking involves:
• Dependent factors
• Loops of causes and symptoms; casuality is often circular.
• Factors are often not equally important; it could be even hierarchical.
Critical thinking is a skill
Critical thinking is the capacity to distinguishbetween beliefs(what we think is true) and knowledge(facts that are backed by accurate observation) helps us separate judgment from facts
Critical thinking involves subjecting facts and conclusions to careful analysis, looking for weaknesses in logic and other errors or reasoning
There is no single formula on how to think critically
Critical Thinking Skill
Why Do I Need to Think Critically?
Prof. Karen J. Warren of Macalester College suggests the following list :
1. Skepticism and independence 2. Open-mindedness and flexibility 3. Contextual sensitivity and empathy 4. Accuracy and orderliness
5. Persistence and relevance 6. Decisiveness and courage
CONCEPTS & RULES
Concept 1
Critical thinking requires one to know as much information about an issue as possible before rendering an opinion or making a decision.
Rule 1
Gather all information :
• Dig deeper
• Learn all you can before you decide
• Don’t mistake ignorance for perspective
CONCEPTS & RULES
Concept 2
To think critically about an issue, one must
understand the terms and concepts related to it.
Rule 2
Understand all terms
• Define all terms you use
• Be sure you
understand terms and concepts others use
CONCEPTS & RULES
Concept 3
Critical thinking requires that we know how
information has been acquired and that we
question the methods by which it was derived.
Rule 3
Questions how information is derived.
• Were they derived from scientific study?
• Were the studies well
conceived and carried out?
• Were there an adequate number of subjects?
• Was there a control group and an experiment group?
• Has the study been repeated successfully?
• Is the information anecdotal?
CONCEPTS & RULES
Concept 4
Critical thinking requires one to search for hidden biases and assumptions that may influence one’s understanding of an
issue or interpretation of data.
Rule 4
Question the source of information.
• Is the source invested in the outcome of the issue?
• Is the source biased?
• Do underlying
CONCEPTS & RULES
Concept 5
Critical thinking requires us to question the
conclusion drawn from facts to see if other
interpretations might be possible.
Rule 5
Question the conclusion.
• Do the facts support the conclusion?
• Correlation does not necessarily mean causation
CONCEPTS & RULES
Concept 6
Our knowledge of the world around us is evolving, so it is
necessary to accept uncertainty as an
inevitable fact of life and make decisions with the best information
Rule 6
Expect and tolerate uncertainty.
• Hard and fast answers aren’t always possible
• Learn to be
comfortable with not knowing
CONCEPTS & RULES
Concept 7
To become a critical
thinker it is necessary to examine the big picture - relationships and entire system.
Rule 7
Examine the big picture.
• Study the whole system
• Look for hidden causes and effects
• Avoid simplistic thinking
• Avoid dualistic thinking
Assignment
1. What’s the difference between scientific inquiry and non- scientific inquiry?
2. From your opinion, which one would be better for
understanding life sciences and technology, system thinking or linear thinking? State your arguments.
3. What is the relationship between systems thinking and
