Introductions Where are you from? What do you teach? Favorite
Hobby? Favorite science class? Why? Workshop Agenda Slide 2 UMASS
RESEARCH CONNECTIONS Slide 3 K-12 Perspective Slide 4 The Nature of
Science Science may be described as the attempt to give good
accounts of the patterns in nature. The result of scientific
investigation is an understanding of natural processes.... Overall,
the key criterion of science is that it provides a clear, rational,
and succinct account of a pattern in nature.... Massachusetts

Slide 11 NSTA Workshop Focus: RAPT and Wrinkles! NSTA participants
will: Learn and use a method for teaching students about patterns
in math and science (RAPT) Learn the interdisciplinary nature of
wrinkling patterns Learn how this workshop aligns with state and
national standards Slide 12 RAPT- a method for teaching patterns
1.R Recognize a pattern exists. Be observant and curious. Why does
the pattern exist? 2.A Ask and Analyze. What information and tools
can be used to understand the pattern? What physical principles are
causing the pattern? 3.P predict the cause and next occurrence of
the pattern 4.T - test the prediction Slide 13 R ecognize a pattern
exists Nanotechology Wrinkles Slide 14 A sk WHY there is a pattern.
Why do some puppies and peas have wrinkles? Slide 15 A nalyze by
classification. Three Categories Spontaneous Engineered-based on a
plan Hybrid (Nanotech) Radiolarians and Diatoms Condensation on a
mirror Nano-texturedmetallic surface Slide 16 A nalyze using
knowledge. Prior Knowledge What do I already know and how can I
apply it to help explain the pattern I see? Acquiring Knowledge
Research Perform experiments Slide 17 A nalyze using physical
principles that cause the pattern Forces What balanced forces
create the wrinkling pattern? Energy Does the wrinkling show stored
(potential) or the energy of motion (kinetic) and stored energy.
Waves vs Wrinkled shirt What are the properties of the material(s)
that create wrinkling? an understanding of patterns helps us deduce
properties of materials and vice versa Materials Slide 18 Predict
--The pattern will occur again given certain conditions Two
round-seeded parent pea plants will produce offspring with round
seeds. x Slide 19 T est hmmmWHAT?????? Slide 20 Much Ado About
Spontaneous Wrinkling funding! Spontaneous wrinkling---application
in nano- materials research Nano-materials micro-electronics and
memory applications Sheet of paper 100,000 nm thick Nano-films
1-100 nm thick Wrinkling patterns used to deduce thickness of
nanofilms Slide 21 Spontaneous Skin Wrinkling Inquiry Model for
deducing properties of materials from observations of wrinkling
patterns Frameworks: MA Frameworks Biology 6-8 6. Identify the
general functions of the major systems of the human body
(digestion, respiration, reproduction, circulation, excretion,
protection from disease, and movement, control, and coordination)
and describe ways that these systems interact with each other. MA
Frameworks Biology High School NGSS SIS1. Make observations, raise
questions, and formulate hypotheses. SIS2. Design and conduct
scientific investigations. SIS3. Analyze and interpret results of
scientific investigations. SIS4. Communicate and apply the results
of scientific investigations. Slide 22 Epidermis - thin with
keratin protein for stiffness Dermis collagen and elastin proteins
offer support and elasticity Subcutis fatty layer SKIN Slide 23 R
ecognize a pattern Procedure: 1.Put index finger and thumb 3 cm
apart in the middle of the top of your forearm. Apply lateral force
to reduce to 2 cm and wrinkle skin. Count wrinkles (peaks). 2.IV:
skin on different parts of the body 3.DV: number of peaks
(wrinkles) 4.Constant: applied opposing forces Slide 24 A sk and
Analyze Are wrinkling patterns different on different areas of the
body? What do we know about skin itself and its form and function
to help us make deductions about the variation in skin on different
parts of the body? (fatty layer, elastin, collagen, keratin, etc)
Slide 25 P redict Lateral vs longitudinal forces? Gender
similarities/differences? Age similarities/differences? UV exposure
differences? Slide 26 T est IV: Gender constants: age, area, force
IV: Age constants: gender, area, force IV: UV exposure constants:
person, basic area, force IV: Latitudinal vs longitudinal
constants: person, area, force Slide 27 Top of forearm (lateral)
top of forearm (longitudinal) Under forearm Top of upper arm top of
hand Slide 28 Spontaneous Wrinkling of Silicone Sheets * Another
model for deducing properties of materials from observations of
wrinkling patterns * Silicone sheets of varying thicknesses are
floating on a corn syrup substrate. Applied force is constant.
Slide 29 Which silicone sheet Is the thinnest? Slide 30 Why Does
this matter??? Wrinkling patterns can be quantified. Data can be
used to make deductions. Using these data, were your deductions
correct based on your observations ? Slide 31 RAPT and Spontaneous
Wrinkling R Recognize Wow, I see a pattern of wrinkling in
different conditions and materials. Ex. skin, silicone and
nano-films!!! A Ask and Analyze What information do I have? Similar
wrinkling patterns occur when there is a adhering substrate and a
film associated with it. P Predict different thickness of skin,
silicone and nano-films T Test Skin activity, silicone activity,
and research on nano-films R.A.P.T. Slide 32 NSTA Workshop Much Ado
About Wrinkles What can we learn about wrinkling patterns in
seemingly disparate events? Slide 33 A wrinkling pattern emerges as
the balance of opposing forces and the interaction of those forces
with associated materials Slide 34 Engineered wrinkling (inherited
trait) Slide 35 Spontaneous Wrinklingbalance of forces Slide 36
Hybrid Wrinkling nanotechnology spontaneous wrinkling with
parameters Slide 37 Wrinkled Peas Inquiry Teaching Inquiry:
Scaffolding Pre-Inquiry Labs that present background information
and tools in order to perform an Inquiry Task. This lab will
investigate why some peas are wrinkled when dry and others are not.
Slide 38 Connection To NGSS HS-LS3-3.Apply concepts of statistics
and probability to explain the variation and distribution of
expressed traits in a population. HS-LS1-6.Construct and revise an
explanation based on evidence for how carbon, hydrogen, and oxygen
from sugar molecules may combine with other elements to form amino
acids and/or other large carbon-based molecules. HS-LS1-2.Develop
and use a model to illustrate the hierarchical organization of
interacting systems that provide specific functions within
multicellular organisms. Slide 39 Gregor Mendel and Wrinkled Peas
Background Information Slide 40 Human saliva and enzymes Lab 1

Analyzing dry and imbibed weights of wrinkled and smooth pea seeds
Lab 3 Slide 43 Putting it All Together, What makes Wrinkled Peas?
Which Peas are wrinkled? Inquiry Lab 4 Slide 44 Picture of peas in
benedicts What pattern classification would you use for wrinkled
peas? A.Spontaneous B.Hybrid C.Engineered Wrinkled peas are
wrinkled because the do not have the enzyme which converts sugars
to starch. When the wrinkled peas are growing, they contain more
water due to the osmotic pressure produced by the sugars within the
pea. When they dry, the outer shell of the pea has an imbalance of
forces on either side of the shell and wrinkles. Slide 45 Patterns
Around Us - Summary Scientists are using principles of patterns in
many different ways, especially with new technologies. Principles
of patterns can help to explain scientific phenomena. Analyzing
patterns is a great way teachers can integrate many different
concepts in order make sense of a pattern. Spontaneous pattern
formation is cool and engaging! Go RAPT your pattern! Slide 46
Final Thought Patterns allow scientist the opportunity to view and
study mathematical principles of the universe. If one knows the
basic mathematical principles of the universe, one can explain why
a pattern occurs.
