Energy Audit Worksheet. Construct one for Vacation Home▪ Imagine you have been hired to audit the energy use of a vacation home in either Vermont (Winter Home) or Cape Cod (Summer Home)▪ Come up with ideas on how the owners can same money and energy▪ Creatively construct a scoring sheet.▪You may use the audit from Friday as a guide

Horizontal Axis-Designed to interact with more wind surface space-Require much larger tracts of land-Act to push wind around them-Better in the ocean

Vertical Axis-Designed to fit into smaller vertical spaces

-Does not require large spans of land

-Some even try to remove friction by using maglev

What are some of the complaints that people use as evidence against?

What are some of the evidences that contradict these complaints?

Who is affected by these complaints or evidence?

Is there any affect to the natural environment?

Are there businesses related to these issues?

To be filled in by students…

Looking at the picture, what do you notice most about the air particles?

A. They move faster across the topB. They move faster across the bottomC. Not Sure

Foils/wings Use the

premise of air pressure to create lift

Air moving faster=Low Pressure

Air moving Slower=High Pressure

High Air Pressure moves towards Low Air Pressure

The main reason that the airplane wing lifts is due to …

A. The pressure below the wingB. The pressure above the wingC. The difference in pressure

above and belowD. None of the Above

How could our understanding of Airplane wings and Bird wings be connected?

Birds (Avian)have Similar Shape wings To Airplanes

Same Principles!!
