I’ve just completed an article on the use of Google Earth as a teaching tool to make decisions about wind farm locations. Read article: Investigating Wind Energy with Google Earth
The suggested activites make use of a number of web sites. Creative Commons images linked to Google Earth come from Geograph. The MAGIC interactive map, an excellent UK government resource provides geographic information on a wide range of environmental themes. The lesson also uses the DTI wind speed database.
Investigating Wind Energy gets students to use a number of fairly simple, yet powerful applications to arrive at a decision about a site for a wind farm. They are handling real geographical data, giving the task lots of credibility. Wind energy is an emotive subject and the exercise will get students to question their own values and attitudes. There is plenty to challenge students of different abilities along with an option to extend the activity with some simple modelling in Sketch Up and Photoshop Elements.
I would welcome feedback!
