Foldable(s)?
Process Skill(s)?
Lesson / Framework Correlations
 Discuss at your table and be ready to share in large group:
 the main topics of study seen in the SLE list
 Are there any shared topics?
 Are there any topics that overlap grades? Which grades?
Lesson / Framework Correlations
 Form a group of 4 people with 2 concurrent grade levels
represented (K-1, 1-2, 2-3, 3-4).
 Choose any SLE.
 Backmap the SLE: discuss what content/skill preparation
students need to have in the lower grade level for
content/skill success in the upper grade.
In your journal, finish this:
Science is…
Science is
 a particular way of understanding the natural world
 an extension of our curiosity
 a connection with past, present and future
 based on our senses and extensions of senses through
instruments
 can give accurate information about the Universe
 very specific as to ‘rules’
 testable and changeable
Science asks
 What’s there ?
 How does it work ?
 How did it come to be this way?
Science works in specific ways

Purpose is to learn about our universe.
Emanates from freedom to explore and wonder.
Follows sensible guidelines.
Relies on evidence from the natural world.
Examined and interpreted through logic.
Uses creative flexibility within certain parameters
Embedded in culture of its times.
Science has principles
 Science seeks to explain the natural world and its
explanations are tested using evidence from the natural
world.
 Science assumes that we can learn about the natural
world by gathering evidence.
Science is a process
 Scientific ideas are developed through reasoning.
 Scientific claims are based on testing explanations against
observations of the natural world and rejecting the ones that
fail the test.
 Scientific claims are subject to peer review and replication.
 The simplest explanation has the advantage.
 There is no such thing as ‘THE Scientific Method.’
 Questioning, investigating and hypothesizing can occur in any
order.
 Theories (well substantiated explanations of some aspect of the natural world)
are central to scientific thinking.
Characteristics of Science

Conclusions of science are reliable, though tentative.
Science is not democratic.
Science is non-dogmatic.
Science cannot make moral or aesthetic decisions.
Science is not always a direct ascent toward the truth.

model of the universe, continental drift
Science corrects itself (plasticity of thought).
 Science is a human endeavor and subject to frailties:
falling in love with one’s own hypothesis and being draw in by preconceptions

Take a blank sheet of paper
Place your open hand in the middle of the sheet
Draw a small dark cross next to the right side of your hand.
Draw a dime sized dot on the paper next to the left side of
your hand.
Hold your left hand over your left eye and the paper at
arm’s length.
Stare at the dot on the left with your right eye only.
Bring the paper close while continuing to stare at the dot.
Notice anything strange?
Try the same thing covering your right eye with your right
hand and staring with your left eye.
What’s happening?
 Blind spot is the spot where the retinal nerves come
together and exit the eyeball through the retina to
form the optic nerve.
 Eyes are not perfect and the sense that we normally see
a complete field of view is an illusion.
Other Illusions
 Sun traveling across the sky
 Moon size at horizon and overhead
 The Earth is flat
 Star locations in sky
 Earth stands still
Deep Ignorance
 What do you know?
 How do you KNOW these things?
 Are you CERTAIN these things are accurate?
 Has anyone discovered something that made what you
‘knew’ be wrong or different from what you thought?
 How would you find out if your knowledge is accurate?
How can Deep Ignorance be challenged?
 Take a minute and list 5 ideas, concepts or understandings
that you know about the natural world and 5 that you
don’t know.
Continuing
 Now share your list with others at your table and, as a
group, choose one to share with the class. Did your group
come up with more ideas than you did alone?
 Write the following statement in your journal:
“Science is important to me because… (fill in with your
own answer.)
Some questions facing science over
the next quarter century:
What is the Universe Made Of?
How can a Skin Cell become a Nerve Cell?
How Does the Earth’s Interior Work?
Are We Alone in the Universe?
How and Where Did Life on Earth Arise?
How Hot will the Greenhouse World Be?
What Can Replace cheap Oil—and When?
How Did Cooperative Behavior Evolve?
What Are the Limits of Conventional Computing?
Welcome to Deep Ignorance
There are things you know, and they fit reality.
2. There are things you think you "know", but they do not fit
reality.
3. There are things you know about, but you don't really know or
understand them.
4. There are things you don't even know you don't know!
This is ...... DEEP IGNORANCE.
 The more we learn, the more we find out how little we know.
 Most of reality, whatever that is, is unknown to us.
 Most of what we do "know" we are not certain of.
1.
Science Is Not A Process That
1. can solve all kinds of problems and questions.
2. can ignore rules.
3. seeks the truth or facts.
4. attempts to prove things.
5. can produce any kind of explanation.
6. produces certainties or absolute facts.
7. can always be relied upon due to its total objectivity and internal selfcorrection.
8. is always properly used.
9. is free from values, opinions or bias.
10. the product (understanding) is based on faith or belief.
11. one solution is as good as another, or is simply a matter of opinion.
And Scientific Theories are not "tentative ideas" or "hunches".
Science is a process to try to understand how the natural
world works.
The inferences that scientists draw from the data
collected is know as scientific knowledge.
There is no certainty in science, only degrees of
probability with the potential for change.
Underlying assumptions in Science
1. The world is real. The physical universe exists, whether
we can sense it or not. It’s not just our imagination.
2. Humans can accurately perceive and understand the
physical universe - such understanding is possible.
3. Natural processes are sufficient to explain the natural
world; non-natural processes are unnecessary.
4. Nature operates the same way everywhere in the
universe, and at all times, except where contrary
evidence is seen.
