Volcanic Eruptions

1. Volcanic Eruptions Fifth Grade WebQuest IntroductionTaskProcessEvaluationConclusionTeacher page

2. Introduction • Volcanoes have erupted throughout our history and do you know, the first surface of the Earth would have looked like a giant lava flow as it was all melted and hardening! Volcanoes are exciting structures that never stop erupting around the world. It is important for you to learn about the earth’s processes such as volcanoes and understand how they work and why they occur because they erupt all the time! IntroductionTaskProcessEvaluationConclusionTeacher page

3. Task • In this WebQuest, you will… • discover how volcanoes form • take a journey to find out the parts of a volcano • discover different types of eruptions • find out where volcanoes are located in the United States • be able to write down a plan to prepare for a volcanic eruption through your research! You will need your science journals to complete this WebQuest and some colored pencils or crayons would be of use. Read the questions and press the control button while clicking the mouse on the desired link to help you figure out the answers. Have fun! IntroductionTaskProcessEvaluationConclusionTeacher page

4. Process • You already know that the Earth is made up of interlocking tectonic plates. Now, take the time to review what two types of plates we learned. Being a detective, find and explain in your journal what the process of subduction is and how it helps in the formation of volcanoes.http://www.pwcs.edu/itech/Resources/TLCF02/tectonics/index.html • Test your knowledge of plate tectonics by playing a game or two. http://www.quia.com/jg/514.html IntroductionTaskProcessEvaluationConclusionTeacher page

5. Process • Before moving on, define these key words in your journal. Lava, magma, igneous rocks, and pyroclastic flow. http://volcanoes.usgs.gov/Products/Pglossary/pglossary.html • Using the terms you know, take a journey to reawaken a volcanic eruption! Draw your own volcano and label the parts given in the website. http://www.pbs.org/wnet/savageearth/animations/volcanoes/index.html IntroductionTaskProcessEvaluationConclusionTeacher page

6. Process • Are there different types of volcanic eruptions? If so, what are they? How are they different from one another? Make a chart with the different types of eruptions and their characteristics. http://library.thinkquest.org/17457/english.html • Do you know what the latest important event in volcano history is? Use this website to search for the date closest to today and record the event in your journal.http://volcano.und.edu/vwdocs/history/EventCalendar.html IntroductionTaskProcessEvaluationConclusionTeacher page

7. Process • Where are some volcanoes located in the United States of America? Find these volcanoes: Yellowstone, Uinkaret Field, Sunset Crater, Wapi Lava Field, St. Helens, Ubehebe Craters, South Sisters, and Hood. http://www.volcano.si.edu/index.cfm will help you to find in what subregion they are located and when the last eruption took place. Record your answers in your journal. • Since volcanoes can cause much damage, is there a way we can predict when a volcano will erupt? How can we monitor volcanoes? What would you do to prepare for a volcanic eruption? Write a paragraph describing what actions or preparations you wouldtake. IntroductionTaskProcessEvaluationConclusionTeacher page

9. Conclusion • You have learned a good deal of information about volcanoes. You have learned how volcanoes are formed, the certain terms associated with volcanic eruptions, the different types of volcanic eruptions, where volcanoes are located in the USA, and how to prepare for a volcanic eruption. Now that you have this knowledge, I want you to research a volcanic eruption around the world and make a poster describing where it is located, when it last erupted, what type of volcanic eruption, and what effect has it had on the world. Lastly, find a picture or draw a picture of the volcano. IntroductionTaskProcessEvaluationConclusionTeacher page

10. Teacher Page • Objectives: Students will understand that the world is made up of tectonic plates and when an oceanic and a continental plate collide, a volcano can form. The students will have a clear understanding of the terms associated with a volcano and the students will find out where certain volcanoes exist in the United States. The students will also make a poster after researching a volcano in the world. • Standards: 3.5.4 A: Describe earth processes. 3.5.7 A: Describe the processes involved in the creation of geologic features (volcanism). 3.5.7 A: Distinguish between examples of rapid surface changes and slow Surface changes.
