IC Lessons Volcanoes This is lesson _5_ of _5__in this IC A. Title of this lesson: Building a Virtual Volcano (optional activity) B. Summary of this lesson In this short visit to the computer lab students apply what they have learned to date about volcanic eruptions to create a virtual volcano. While the lesson has high kinesthetic engagement value, the emphasis should be on gathering and use of evidence, and explaining why the evidence supports a claim about a volcano’s explosive force. Generative Question(s): Why did Mt. St. Helens explode with so much force? (Why does a stratovolcano’s eruption result in an explosion of gases and rock, instead of lava plumes?) C. Objective(s)/Learning Goal(s)/ Key Student Learning(s) of this lesson Students will understand (content knowledge): 1. Both viscosity of magma and gas content are factors which interact to produce eruptions characteristic of particular types of volcanoes at particular kinds of plate boundaries. 2. Make a prediction of the response to sudden release of pressure in substances with high and low gas content. 3. Describe where areas of high and low pressure are in a given situation. 4. Build on ability to predict the shape of volcano (shield or composite) by the gas content of the magma. 5. Locate volcanoes on a world map using latitude and longitude. 6. Describe the different volcanic eruptions by their explosivity index (VEI). 7. Connect the location of volcanoes in subduction zones with the type of magma (thick or thin) and shape (shield or composite) and their explosivity Created by San Lorenzo Unified teachers (2012): Linda Preminger, Julie Ramirez, Marilyn Stewart, and Lawrence Yano IC Lessons Volcanoes This is lesson _5_ of _5__in this IC (gentle or violent) and make a statement about the relative danger to human life. Students will be able to (process skills): 1. Navigate the internet in a school computer lab, and locate relevant information in response to specific content questions. 2. Work cooperatively with a partner in developing a written synthesis of evidence collected over several lessons. D. Teacher Background Knowledge for this lesson In this lesson, 6th graders will gain an appreciation for the combined characteristics of silica content and gas pressure, which are two major factors determining the types and force of volcanic eruptions. There is high student engagement in manipulating the varying degrees of both characteristics. Even if the students are working in pairs, all students should have the opportunity to sit at the controls and play with the results. Allow sufficient time, however, to bring students back to the purpose of the lesson, which is to be able to explain why different volcanoes in different types of tectonic plate boundaries behave in different ways, and use key points of evidence to provide reasoning for their claims. E. Prior knowledge that students need to understand this lesson - with an assessment to determine what they already know (if appropriate). Students will need to understand the meaning of viscosity (resistance to flow); that some volcanoes erupt with very fluid lava while other volcanoes erupt explosively in clouds of rock and ash, with pyroclastic flows that can cause devastation over huge areas; and that most shield volcanoes with gentle, fluid eruptions occur over geologic hot spots, and that most strato- and composite volcanoes occur at convergent subduction zones.

Lesson Plan – detailed, numbered, step-by-step plans. Introduce the lesson by showing videos of the 1980 Mt. St. Helens eruption; the more recent fiery eruption of Mt. Etna; and an eruption of Kiluaea; or Loihi erupting under the ocean. 1) Ask students to make verbal assessments of which volcanoes have thick, sticky, viscous magma. Accept their answers. Look for uncertainty, and expect students to have different opinions of Mt. Etna and Loihi. 2) Then tell students, today, we’re going to visit a volcano on-line. We’re going to the computer lab, where you will complete some reading, answer questions, and then visit a virtual volcano. You will have the opportunity to manipulate not just the viscosity of the magma, but also the gas content of the magma, and learn more about the characteristics of certain volcanoes. By the end of the lesson, you should be able to choose a volcano from the list, and based on what you’ve learned, determine the general Created by San Lorenzo Unified teachers (2012): Linda Preminger, Julie Ramirez, Marilyn Stewart, and Lawrence Yano IC Lessons Volcanoes This is lesson _5_ of _5__in this IC characteristics of the volcano. Tomorrow we’ll experiment with aspects of pressure and how the sudden release of pressure affects volcanic eruptions. 3) Assist students in logging on to the website: http://kids.discovery.com/games/build-play/volcano-explorer 4) Allow students to explore the site on their own for 20 minutes; just be available for questions. 5) After students have had a chance to check all the variations of gas content and viscosity, and read the examples and explanations, ask them to choose one volcano from the prior list, and, based on location and Volcanic Explosivity Index, explain in a paragraph how they anticipate the eruption characteristics of that volcano. The hypotheses must be supported with at least the following evidence: a. Location of the volcano in a subduction zone or geologic hot spot. b. Location of the volcano on a continental or oceanic plate. c. Relative Explosivity of the volcano, compared to other volcanoes in similar (and different geographic locations). d. Classification of the volcano as stratovolcano, shield volcano, or cinder cone. K. Vocabulary words – key vocabulary words that are targeted or taught as part of the lesson. (Understanding these words is essential for students to understand the key concepts of this lesson.)

Potential Pitfalls for: a. student understanding; b. laboratory mishaps and common procedural errors; c. academic vocabulary issues, etc. The application does not run on all systems, and some school districts may restrict access to websites that are considered game-based. Test the website and application well in advance of the lesson, and be prepared to run as a demonstration if necessary. Otherwise, this is an opportunity for students to explore and apply what they have learned to a computerized volcano model. It is an opportunity for the teacher to determine any remaining misconceptions and guide students through the evidence so they are prepared to complete the same kind of synthesis of information on the final assessment for this unit. M. Differentiation: Modifications for English Learners, advanced learners, struggling learners, etc. Allow for simple sentences among English learners, but encourage the use of the most important vocabulary: high viscosity and high gas content for stratovolcanoes; and low viscosity, and low or high gas content for shield volcanoes.
