Creating New Teams
• Number off 1 – 12• Pack and stack and move to new table• Introduce yourself to your new teammates
COLLABORATIVE INQUIRY USES NORMS!
• Keep everyone engaged in the research & design
• Consider each idea as viable• Share materials• Identify jobs/role for each member
of the team• Expect Cognitive Dissonance!
INTEROFFICE MEMORANDUM
TO: ASSOCIATION OF WASHINGTON SCHOOL PRINCIPALS – COHORT 3
FROM: US DEPARTMENT OF ENERGY EFFICIENCY AND RENEWABLE ENERGY (EERE)
SUBJECT: RESEARCH AND DEVELOPMENT OF A PROTOTYPE WINDMILL
DATE: JULY 24, 2012
The United States Department of Energy’s Efficiency and Renewable Energy Division has recently been asked by President Obama and his administration to assume responsibility for the research, design, and development of localized personal-use windmill projects. These personal-use windmills are in direct response to the desire to use alternative renewable energy as well as to reduce the individual homeowner’s utility costs. On Tuesday, July 24, 2012 the EERE submitted a request for proposals to conduct the necessary research and development to create prototype windmill blades for electrical generation windmill that could be constructed, by the general public, with easily obtainable materials. Because you have gathered a set of creative and innovative thinkers at Sleeping Lady, the EERE is asking the principals of AWSP to conduct the initial blade research using the materials provided. You will have just over 24 hours to conduct your research and report your findings on blade design in the assigned category. The timeline is short due to the difficult situation being faced across the country with dwindling fossil fuel reserves. Please be prepared to present your team’s prototype to an expert panel Wednesday, July 25 shortly before noon. Your team of researchers will demonstrate the blade designs you have created for electricity generation. The team who generates the most electricity will be awarded with a contract for further R&D as well as funding to produce a marketable windmill blade design. We wish you great success and look forward to the outcomes of your research.

Time for Lunch
You will be testing…• 20 minutes per station:
• STATION ONE (Flicker): Blade Number• STATION TWO (Nuthatch): Blade Shape• STATION THREE (Dipper): Blade Length• STATION FOUR (Tadpole): Blade Pitch
Tips for Success• Explore and discover but…– Ensure that the dowel is fully inserted into the hub– Blades should all face the same direction– Pitch should be maintained across all blades– Direction matters – you should record positive values NOT
negative values– Observe, record, be curious if something doesn’t make sense– If time, experiment beyond the station procedures– If you see a trend, follow up on it…– Safety first (use the safety glasses)!
Start cleaning up at 3 p.m. and be back in the room at 3:15 p.m.
Summarizing the Data…• Thus far…– What do you know now that you didn’t know
before?
– How will you share your findings tomorrow?
