Welcome to:Biomimicry- Using nature to inspire sustainable design in science class Friday 9:00 - 11:00 Presenter: Dan Gross email@example.com
Goals Connections: meet each other Adjust Agenda for this session to meet everyone’s needs Introducing Biomimicry to students Out of your seat biomimicry activities Biomimicry PBL explanation Links on the web/and my website If there is time: Design your own sustainable invention inspired by nature
Connections Any background you want to share Experience with biomimicry What you want out of this sessionSipping through a foot, the thorny devil lizard of the arid Australian desertdemonstrates its ability to wick water to its mouth via channels between its scales.Scientists hope to mimic the mechanism to develop water-capture technologies fordry regions.
Inspirations Earthwatch Institute William McDonoughHow could a tree inspire design? Janine Benyus Thomas FreidmanPreparing students for the 21st century Nature
Introducing biomimicry to your students
On your Do-Now paper…….. 1. What do you think is the most creative piece of technology ever? 2. What human problem does this piece of technology solve? 3. What problem do you think inspired the development of this technology?
What do these have in common? Older students: How does nature inspire technology? Location: Sahara Desert Location: city in a desert Termite Mound Largest building in Zimbabwe. Can be millions of termites in 1 mound Energy Design Challenge:. Termites never sleep Keeping the Building cool without. Used to be used to find gold wasting a lot of electricity. Side note: Chance to share wonder ofnatural world Hypothesis ________________________________________________________________
Temp: constant 87 deg Base of the chamber is cool wet mud that has openings that redirects air up. even though outside temp. Constantly build new vents and close old ranges from 100-40 deg in ones to regulate temperature. 1 dayExplanation ____________________________________________________________Building designers saved A/C energy by opening/closingvents and storing cold air.
What do these have in common?40-50 ft long Design Challenge: Harness the most energy possible from well designedUp to 80,000 pounds bladesMax load of an 18 wheeler Hypothesis: _______________________________Eat Krill 2” long _________________________________________
VS. Which is more efficient? 8% improvement in lift 32 % reduction in dragExplanation:Ridges on the edges of windmill blades, like ridges on a whale fin, create morepower with less drag and more lift
Tangent “When you step into the intersection of different fields/disciplines/cultures, you can combine existing concepts into a large number of extraordinary new ideas.” - Frans Johansson “The Medici Effect”
What do these have in common? Shark skin Boat Keel . Non-Smooth Skin Design Challenge: Marine life grows on keel . Sharks are self- cleaning Marine life on keel = Skin does not collect marine slower speed life chemicals needed to cleanHypothesis ________________________________________________________________
How can designers use shark skin design on a keel to keep marine life off……. Sharkskin Paint- with scale-like texture . 4-5 knots self cleaning . 67% reduction marine life on keel Explanation:Paint is scaly and allows water to get in-between scales to push off marine life.
What do all of these examples have in common? Biomimicry: Break down the word Bio- life Mimicry- imitate Definition: Developing sustainable technologies inspired by nature Sustainable: How do you define sustainable? Lasts a long time/reusable Less harmful Uses less resources like energy Why it works: life has been adapting to earth for 3.8 billion years, we have a lot we can learn from life on earth
Activities to get students thinking like a sustainable designer inspired by nature Read your card to yourself Find your match: picture and description Example: card card more fuel efficient car Match up nature’s solution with design challenge Example nature’s solution design challenge box fish more fuel efficient car Figure out how nature can inspire the solution to the design challenge
PBLShort videoPass out PBLEmphasis on Sustainability
Putting your creativity to the test… Existing Example of Biomimicry a. identify the part of nature in your picture b. identify the technology in the picture Read the explanation under the photo. c. explain how “nature” inspired the technology on your sheet d. what is the purpose of the technology? e. Why is the technology sustainable.
Examples of completed Student Projectswith different levels of application drawings made on Smartboard program
Fennec Fox Hot air leaves here. Fur reflects the heat to keep the animal cool.The Fennec Fox has reflective fur that keeps itcool. It’s big ears act like a vent for hot air toescape its body.
A “Cool” Ride This is the reflective paint. Cool air enters the car here.Heat leaves the car. This car (shown above) has reflective, non-toxic paint so it reflects light. It also has air vents so that cool air comes in and it pushes the hot air out. This lowers the use of air conditioning and stops people from cutting down trees for money.
Fire resistant House off ground Houses off the ground where wild fire are Sand pine frequent so it doesn’t catch house on fire High off the ground as easy. If the support beams are made so it doesn’t catch on out of concrete it is sustainable and can fire so easily. be used over and over again. fire

It can also at room temperature, and produced prevent things from getting dirty. on an as-needed basis •From studying the giraffe’s hair weOur invention is sustainable because all can watch the process of how theof the ingredients in it are non-toxic and chemicals are made and mix together.fairly common. After that, it is a simple matter of making an artificial version.

The Black Jewel Bio- Our Invention Mimic- Beetle The Forest Fire Detector This invention is a special wrist band that beeps when there is a forest fire for firefighters and forest rangers. It is solar powered and The Black Jewel Beetle has when it is dark out it uses its stored special sense organs that can energy to work. sense forest fires up to 50 miles away
