Geothermal Energy~ Day 1 Have your science at your table Title: Geothermal Energy Date: 02/03/14 Update your table of Contents

Vocabulary Connection geo = relating to the earth therm = heat geothermal = relating to the internal heat of the Earth Geothermal energy is power generated from natural steam, hot water, hot rocks, or lava in the Earth's crust. What other words have the prefix “geo” in them? How do those words relate to “the Earth”? What other words have the prefix or root word “therm” in them? How do those words relate to “heat”?

Where Geothermal Energy is Found Geothermal reservoirs are naturally occurring areas of hydrothermal resources. They are deep underground and are largely undetectable above ground. Geothermal energy finds its way to the earth's surface in three ways: Volcanoes (or holes/cracks in the earth’s crust) Hot springs Geysers (See Old Faithful erupt: http://youtu.be/wE8NDuzt8eg ) When magma comes near the earth's surface, it heats ground water trapped in porous rock or water running along fractured rock surfaces and faults. Hydrothermal features have two common ingredients, water (hydro) and heat (thermal). Geologists use various methods to find geothermal reservoirs. Drilling a well and testing the temperature deep underground is the most reliable method for locating a geothermal reservoir. Why does Old Faithful erupt on a schedule? Check this out to see how geysers erupt and recharge: http://youtu.be/X4zA_YPCyHs Source: U.S. Department of Energy, Energy Efficiency & Renewable Energy

Geothermal Energy Basics Most geothermal resources are near tectonic plate boundaries The most active geothermal resources are usually found along major tectonic plate boundaries where earthquakes and volcanoes are located. One of the most active geothermal areas in the world is called the Ring of Fire. Source: U.S. Department of Energy, Energy Efficiency & Renewable Energy

Geothermal Energy Basics See how geothermal energy creates electricity: be ready to write this in your own words http://youtu.be/rfUQy86ZMpQ

Geothermal Energy Your teacher will demonstrate how power plants help us harness the energy of the earth . In your notebook, sketch the model and label the parts. Write in your own words how electricity is generated using geothermal energy.

Geothermal Energy What conclusion can you make about how geothermal power plants work? <Answer at least 1 in your journal> I used to think _____, but now I think ___. Based on the information I just learned, I conclude that ___ is important because ___. Because of ___, I now understand why ___. What testable questions do you have now? What variables would you be testing and which variables must you control?  

Geothermal Energy Evaluating models: With your table group label Your illustration with the following information   What do these things in our model represent? The boiling pot of water? The steam? The aluminum foil? The can? The pinwheel? What are the limitations of this model?  

Geothermal Energy You and your partner will complete the Geothermal Row in your Energy chart… You already have this saved….. Complete Row 2. Alternative Energy Definition How does it make energy? Examples/ Picture Hydroelectric   Geothermal Wind BioMass Solar

Day 2 Research Open your Research Document and complete a 2nd form for Geothermal You will use the Symbaloo website from Mrs. Aldridge’s web page as part of your research. Remember to save your changes with the blue square in the top left corner of your screen.

Geothermal Energy Research Use these links and the printed resources that your teacher provides to inform the public about geothermal energy. Include the same categories of information that you used to tell the public about the other forms of energy you have studied.
