Knowledge of Science, scientific temper and use of method of science by the people are the key requirements for the growth and development of a society and the nation. Practically every body having knowledge of science or not use the method of science. Let us see how?

1. Exploring
a Scientist
in
Ourselves

2. well
educated &
have degree
in Science
well
Educated but
don’t have degree
in Science
Not well
educated
But a common thing among most of the people from these groups is
They act scientifically and they have a scientist in them

3. Whom can we call a Scientist?
Can a Doctor be called Scientist?

4. A scientist is a person who...
 is curious about the world
Galileo Galileo's curiosity about the heavenly bodies made him the
first person to use a telescope to study the moon, the sun, the
planets and the stars.
 is logical and systematic
Among the reasons why Gregor Mendel discovered the principles of
heredity when others have failed was his logical experimental
methods and his careful and accurate record keeping.
 Is open-minded and free of bias
An open-minded person is one who can modify plans or discard
hypotheses if necessary. One such person was Johannes Kepler
who was hired to develop evidence that planets moved along
perfect circles.

5. A scientist is a person who...
 Is intellectually honest
Isaac Newton built his laws of motion on the previous work of
Galileo and others and he gave them credit
“If I could see little farther than others, the reason was that I was
sitting on the shoulders of giants like Galilio and Kepler”
Newton
 works hard and is persistent
Marie Curie was the first person ever to be awarded the Nobel Prize
twice. It was not surprising considering how hard she worked to
extract a grain of radium after processing hundreds of tons of
residual waste of Pitch bland.
 does not jump to conclusions
John Dalton's atomic theory was backed by experimental evidence.
He was not the first to propose that the atom was the smallest
particle of matter, but he was the first to use experimental evidence
to support his theory.

6. A scientist is a person who...
 is a creative and critical thinker
Albert Einstein was able to derive his theory of relativity
because he went beyond what was given and known at
that time. He saw links and connections where others did
not. He looked at things from different perspectives.
 is rational who believes that every thing that
happens has a reason
 is willing to suspend judgment until he is sure of his
results
 tries new approaches to arrive at solutions

7. Where do we stand?
 All of us have considerable knowledge of
science.
 Is it so?
 We apply Scientific principles/concepts in our
day to day life even without knowing.
 Is it true?
 We use method of science in our daily life for
solving different problems.
 Is it so?

8. All of us have considerable knowledge
of Science
 Health related – knowledge about diseases, their
prevention, medicines, food, nutrition, vitamin, and
so on
 Measurement – time, length, volume, speed,
temperature etc
 Energy – heat, light, electricity, fuels their use
 Environmental issues and problems (global
warming)
 Importance of oxygen for breathing, burning,
 Importance of carbon dioxide for fire extinguishing,
food production by plants etc

9. We apply Scientific Principles in our
daily life even without knowing them
 Cooking – making burner shim after one whistle or
once boiling
 Bucket – knowing with seeing whether it is filled or
not
 Choice of clothes – which type of clothes to use in
which season and why
 Bending our body on a side while carrying bucket
full of water in a hand
 Leaning forward while climbing a mountain
 Bending of a cyclist while taking turn on a curved
road

10. Let us do some activities
 Standing from the chair
 Pick up coin while standing against a wall
 A coin on card board placed on a glass

11. We use method of science in our daily
life for solving different problems
 You arrive home late at night, walk up to your
house door, unlock the door, reach to the
light switch just inside the front door and
switch on it.
 Encounter a Problem The light does not
come on!
 As a normal human being, what do you do in
this situation?, .

12. We use method of science in our daily
life for solving different problems
 Observation: Switch on, but still it is dark
 Question: Is the Power Out?
 Hypothesis: If power is out, there should be no light in neighboring
houses
 Experiment Observe neighborhood lights (indirect
evidence)
 Analysis If any house has lights If all houses dark
prediction fails, Prediction holds
 Conclusion Reject hypothesis Accept hypothesis
(Power is not out) (Power is out)
 Possible error It may be because of Inverter or Generator
If power is there, still lamp does not lights. What will you do
next?

13. Method of Science
Revised experiment Try another switch in the house, with a revised
hypothesis/prediction
Hypothesis/prediction If the power is out then none of the lamps in the house
should turn on.
Analysis If lamp works, prediction fails, as a conclusion You
reject hypothesis
If lamp does not light, prediction is supported, as a
conclusion you accept hypothesis
Question: Is light bulb burned out?
Is lamp plugged in?
Hypothesis/Prediction If bulb is burned out, then the old bulb will not light
another lamp
And so on…..

14. Method of Science

15. Comparing two approaches to problem
solvingThe scientific approach The common man’s approach
Identification of a problem (specific
question)
Hypothesis formulation
Methodology (Experimentation)
Data and Information Collection
(Systematic way)
Analyzing data
Conclusion (for the masses)
Ordinary questions
Guess ("This fruit is eatable")
Methodology (trial and error)
Data and Information Collection (not
so systematic )
Analysis
Conclusion (for the Individual)

16. Are the following statements scientific?
And why?
 The moon exists only if it is observed, when no
one is observing it, it’s not there.
 The sun rises in the east in the morning.
 The sun is not going to rise in the east in the
morning tomorrow.
 You can get on the bus of exact number at 07:00
every weekdays morning.
Are the predictions or explanations of Stock Markets
provided by finance commentators (i.e. TV,
newspaper or radio) “scientific”?

17. In order to keep
the Scientist Alive in Ourselves
We should
 be keen observer
 be curious about the world (why and how)
 think rationally and shun blind faith & superstitions
 Be logical and systematic in our daily activities
 be open-minded and free of bias
 Be ready to accept positive criticism
 be intellectually honest
 not jump to conclusions without having firm evidence
 be creative and critical thinker
 try new approaches to arrive at solutions
 Pursue our goal persistently

18. Thank You
Think Scientifically
Act Scientifically
Live Scientifically
