Geothermal Energy Webquest
Introduction
As you learned in my presentation, geothermal energy is derived from the fact that the earth's mantle and core hold tremedous heat - largely due to pressures deep below the earth's surface.  That heat is evident whenever there are thin areas in the earth's crust, especially in regions of volcanic activity, hot springs, and geyser fields.

For centuries, people took advantage of the earth's heat by using it to directly warm their homes or for bathing purposes.  We have also long known that energy from the earth's mantle can be used indirectly to create electricity.  The link comes through steam, which can drive electrical generators.

Many people believe that geothermal energy holds great promise as a viable alternative to coal, shale gas, and nuclear fission for generating electricity.  Others are not so sure, due to their belief that geothermal has limitations.

The purpose of this webquest is to enable teams of students to learn more about geothermal energy, and determine its potential to serve as a significant source of alternative energy in the future.


Task
The teams assigned to this webquest are to review the websites listed below.  Students in those teams are to answer the following questions:
  • What evidence supports the idea that geothermal energy can provide a significant proportion of electrical demand in the future?
  • Does everybody agree with that evidence?  If not, explain.
  • We know that geothermal energy generation is localized. 
    • Can production be enhanced in those areas in which it is already developed?
    • Can production be developed in areas (like Pennsylvania) where geothermal is minimally developed?
  • What environmental problems does geothermal pose?
  • What social / political problems?
  • Do any laws or regulations prevent the deployment of geothermal energy?
  • What emerging technologies may enhance the utilization of geothermal?
  • Can geothermal energy run out?
Process
Student teams assigned to this topic will conduct a webquest using the following websites:
On 19 November, student teams assigned this topic will each give a 20 minute Powerpoint-based presentation in which they will answer the questions.

Evaluation
Students will be evaluated using the following rubric.  The grade will reflect both an individual and a team performance.
