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 Department of

Todays Learning Goals

• Be Observant
• Ask WHY there is a pattern.
• Use and develop tools to help understand
  patterns.
• Apply physical principles to evaluate new pattern
  observations

9
1. Be Observant - Wrinkles
Nanotechology Wrinkles
10
2. Ask WHY there is a pattern.

• Why?

• Balance of forces
• Properties of materials
• Forms of energy
• Potential
• Kinetic

11
2. Ask WHY there is a pattern.

• Three Categories

• Spontaneous
• Engineered
• Hybrid (Nanotech)

Condensation on a mirror
Radiolarians and Diatoms
Nano-texturedmetallic surface

3. Use and develop tools to help understand
patterns.

• Background Knowledge

• Acquiring Knowledge

• What do you already know and how can I apply it
  to help explain the pattern I see.

• Research
• Perform experiments

13
4. Apply physical principles to evaluate patterns
- Overarching Principles

• Forces

• Energy

Materials

• What balanced forces create the wrinkling
  pattern?

• 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

14
Today Wrinkles around us.
These wrinkles can tell you something about the
properties of these material

Agenda

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

16
Determine dry weight of you peas

• Read through third activity in Peas in a Pod
  Laboratory (page 9)

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.

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? WHY?

Wrinkled Peas- Connection To Frameworks

• Biology 6-8
• 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.
