Blowing in the Wind (11-14)
This resource, from Siemens UK, looks at the use of wind farms to provide sustainable energy for a range of communities in a variety of settings. The selection of a New Zealand context is significant as Maori communities see themselves as being responsible for effective stewardship of the land for future generations.
Students consider the factors that affect the design of a wind turbine and consider how these might impact on each other. They then investigate various factors to come up with an optimum design, such as number of blades, length and shape of blade and angle, using their data to justify their conclusion.
