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....

Todays Learning Goals
1. Be Observant
2. Ask WHY there is a pattern.
3. Use and develop tools to help understand
patterns.
4. Apply physical principles to evaluate new
pattern observations
1. Be Observant - Wrinkles
Nanotechology Wrinkles
2. Ask WHY there is a pattern.
Why?
• Balance of forces
• Properties of
materials
• Forms of energy
– Potential
– Kinetic
2. Ask WHY there is a pattern.
Three Categories
• Spontaneous
• Engineered
• Hybrid (Nanotech)

3. Use and develop tools to help
understand patterns.
Background Knowledge
Acquiring Knowledge
• What do you already • Research
know and how can I • Perform experiments
apply it to help
explain the pattern I
see.
4. Apply physical principles to evaluate
patterns - Overarching Principles
Forces
Materials
• What are the
• What balanced
properties of the
forces create the
material(s) that
wrinkling pattern?
create wrinkling?
• an understanding
of patterns helps
us deduce
properties of
materials and vice
versa
Energy
• Does the
wrinkling show
stored
(potential) or
the energy of
motion
(kinetic) and
stored energy.

Agenda
• Determine dry weight and soak your peas.
• Wrinkles in skin inquiry
• Wrinkled Peas
Determine dry weight of you peas

Skin Wrinkles - Connection To
Frameworks
• Science:
• 2.5. Systems in Living Things: Describe the
organization of multicellular organisms from cells
to tissues to organs to systems to organisms.
• 2.7. Reproduction and Heredity: Recognize that
every organism requires a set of instructions that
specifies its traits. These instructions are stored in
the organism's chromosomes. Heredity is the
passage of these instructions from one
generation to another.
Inquiry – Wrinkles in Skin
Inquiry – Wrinkles in Skin
Inquiry – Wrinkles in Skin
Understand wrinkling patterns in skin
RAPT
• R – Recognize – Wow, I see a pattern!!!
• A – Analyze – What information do I have?
– Testing skin at different parts of the body.
• P – Predict – Your Choice
• T – Test – Was your prediction accurate?

4. Recognize that within cells, many of the basic functions of organisms (e.g.,
extracting energy from food and getting rid of waste) are carried out. The way
in which cells function is similar in all living organisms.
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.
16. Recognize that producers (plants that contain chlorophyll) use the energy
from sunlight to make sugars from carbon dioxide and water through a
process called photosynthesis. This food can be used immediately, stored for
later use, or used by other organisms.
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.
