2. 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”?

3. 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: )
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:

4. 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.

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

6. 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.

7. 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?

8. 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?

10. 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.

11. 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.
Research links (This is a Symbaloo that has links to many different sites – not just wind turbines):
