2201 Goals & Guiding Intentions
• …provide hands-on experiences that foster
thinking and a “sense of wonder”
• …involve students in ongoing dialogue
and development of science knowledge for
teaching
• …equip students to modify and apply these
science activities for their K-8 students

Only the brave should teach…
“It is noble to teach
oneself, it is still
nobler to teach
others”
--Mark Twain
(…and how great
an honor to teach
teachers!)
Why Teach?
On the first day of school…
“It was boring. We talked about
the number one and I fell
asleep. It was nothing like in
my dreams.”
(Lauren, 6)
On the second day of school…
“I sat there, like a dog,
begging to go home.”
(Lauren, 6)
Your philosophy of education…
• Axiology = What is of value?
• Ontology = What is real?
• Epistemology = How do you know?
What is the single most
important factor in
influencing learning?
Kid quotes on love…
What is the proper age to get married?
• “Eighty-four! Because at that age, you
don’t have to work anymore and you
can spend all your time loving each
other in the bedroom.” (Judy, 8)
Kid quotes on love…
What do most people do an a date?
• “ On the first date, they just tell each
other lies, and that usually gets them
interested enough to go for a second
date.” (Mike, 10)
Kid quotes on love…
On the role of good looks in love…
“If you want to be loved by somebody who
isn’t already in your family, it doesn’t
hurt to be beautiful.” (Jeanne, 8)
What is the single most
important factor in
influencing learning?
Educational Psychology: A Cognitive View
(Ausubel, 1968)
“The single most important factor in
influencing learning is what the learner
already knows. Ascertain this and teach
accordingly.”
Teaching is a basic human act.
• behaviorist psychology
• constructivist epistemology
• Beware of false dichotomies.
Both are of use in our “best
practice.”
Discussion…
Science teaching at its worst and best.
Rachel Carson,
The Sense of Wonder
"If children are to keep
alive the inborn sense of
wonder, they need the
companionship of at
least one adult who can
share it, rediscovering
with them the joy,
excitement and mystery
of the world we live in."
Activity: Draw a Scientist
Take a few minutes with a pencil and
paper and draw a scientist at work.
Draw a Scientist?

Draw a Scientist?
What’s the point?
Agree or Disagree?
• When cows fall asleep standing up, it is
easy (and fun!) to sneak up next to them
and tip them over.
• Birds eating rice thrown at weddings swell
up and die (even burst).
• Animals exposed to radioactive waste
mutate and turn into other types of animals.
Agree or Disagree?
• Earthworms come up onto the sidewalks
after heavy rain to avoid being drowned in
their underground tunnels.
• People licking toads have hallucinations.
• Lennon wrote better music than
Tchaikovsky.
• Heaven is not in our solar system, but it is
somewhere in the universe.
Science…
• Much of science is organized common
sense about the physical world.
• Science is a body of knowledge.
• Science is the process of discovering and
explaining the order of nature
SCI 2201: Concepts in Science
• Science: A Way of Knowing
• Trefil & Hazen, The Sciences chapter 1
Great Idea:
Science is a way of asking and answering
questions about the physical universe.
From Science for All Americans
(1990, AAAS, Project 2061)
• --things and events in the universe occur in
consistent patterns that are comprehensible
through careful, systematic study.
• --through the use of the intellect, and with
aid of instruments that extend the senses,
people can discover patterns in all of
nature.
Life Sciences

•
•
•
•
•
Biology
Botany
Ecology
Genetics
Zoology
etc
Physical Sciences
•
•
•
•
•
•
Astronomy
Chemistry

etc
• Subject Matter Knowledge for
Teaching
• Science Literacy
Knowing it well enough to teach!
“Pedagogical Content Knowledge”
• Evaluate your PCK in
Physical Science:
• Physics
• Chemistry
• Astronomy
• Meteorology
• Geology
“The Scientific Method”
1) Question or Problem
2) Hypothesize
3) Predict Consequences 4) Experiment
5) Interpret Experimental Results
The Scientific Method
• There is simply no fixed set of steps that
scientists always follow, no one path that
leads them unerringly to scientific
knowledge.
Science involves…
•
•
•
•
•
•
Using and extending the senses
Observing and collecting
Probing and testing
Deductive hypothesis testing
Inductive search for patterns
Building increasingly accurate
explanations based on evidence
Mendeleev and the Periodic
Table of Chemical Elements
Fleming and the serendipitous
discovery of the first antibiotic
Goodall and the willingness to
break with convention
“If I have seen farther it is because I
stood on the shoulders of giants.”
“Science Is Not Words”
by Richard P. Feynman
• “Shoe leather wears
out because it rubs
against the sidewalk
and the little notches
and bumps on the
sidewalk grab pieces
and pull them off. To
simply say it is
because of friction is
sad, because it is not
science.”
The world looks different after learning
science…
“Trees are made of air, primarily. When they
are burned, they go back to air. In the
flaming heat is released the flaming heat of
the sun which was bound in to convert the
air into tree…”
These are beautiful things, and the content of
science is wonderfully full of them.”
The Scientific Attitude
• Inquiry
• Experimentation
• Humility before the facts
Fact, Hypothesis, Law, Theory
• Fact = a stated observation
• Hypothesis = a proposition that may
be investigated
• Law or Principle = a description of
observable phenomena
• Theory = an explanation based on
extensive evidence
Science, Art, Religion
Three ways that humans experience and express:
art, science, and religion.
Art
Religion
Science
Helps us reflect.
Asks “Why?”
Asks “How?”
Allows us to
express the best
of our humanity
Deals with
ultimate
purpose,
wisdom &
belief
Search for
patterns, builds
explanations on
evidence
The Borderlands of Science
Shermer, (2001)
• Normal Science
– Empirical claims
– Vast body of evidence
• Borderland Science
– Empirical work
– Growing body of evidence
• Pseudoscience
– Fake science disguised as
normal science
– Lacks evidence
10 different areas of inquiry:
•
•
•
•
•
Acupuncture
Astrology
Big Bang
Big Foot
Chiropractic
• Heliocentrism
• Hypnosis
• Neurophysiology of
Brain Function
• Punctuated
Equilibrium
• Search for
Extraterrestrial
Intelligence (SETI)
