1. Unit Timeline Overview Matrix of Entire IC IC name Volcanoes_ Lesson Parts 1 2 Anatomy of a Volcano Mapping the World’s Volcanoes Class time Lesson Objectives Prep Time Lesson Preparation Key Vocabulary 1 50minute period 1. 2. 3. Describe the parts of a volcano Distinguish between magma and lava Explain the different phases that a volcano can go through in a “lifetime” 1-1/2 hrs 1) volcano, magma, magma chamber, lava, caldera, vent, dike, sill, conduit 1 50minute period 1. Students know the ring of volcanoes that circles the Pacific Ocean is called the Ring of Fire. Several subduction zones border the Pacific. Given latitude and longitude, students can locate volcanoes on a map of the world. Identify geologically-significant tectonic plate boundaries and volcano types. Learn difference between low and high viscosity Create and compare data on a table and in a graph. Characteristics of density and viscosity of a substance are different properties. Make a prediction of the flow rate of different liquids and test them. Predict the type of magma a volcano will have based on its shape. Connect the location of volcanoes on subduction zones viscous magma and explosive eruptions. 30 mins 2. 3. 4. 3-4 The Great Viscosity Race 2 ea 50min periods or 1 90min block 1. 2. 3. 4. 5. 6. 5 Sudden Release of Pressure and Highly Explosive Volcanoes 3ea 50minute periods or 2 90min block with 1. Students practice English-to-metric conversion 2. Use of conversion factors. 3. Observe effects of pressure change. 4. Students are introduced to Newton’s Third Law. 2) 3) 1) 2) 3) 4) 1 to 11/2 hrs 1 hr 1) Copy Volcano Anatomy diagrams and terms (1 per student); Prepare jello mold volcano; fill flavor injector with chocolate syrup; Prepare flour caldera. Copy Connecting Volcanoes to Plate Boundaries (1 per student) Have ready Bathymetric Maps (1 per every 2 students), and set of adhesive labels (1 per table team) Make classroom Bathymetric of Plate Tectonics map available. Provide rulers and markers Prepare stream table raceways: line with foil and mark lanes 2) Line catch basins with foil 3) Pour liquids into cups and label contents. 4) Pour sand into cups and label contents. 5) Pour additional cup of corn syrup per group, and refrigerate. 6) Copy Viscosity Probe (2 per student) 7) Copy The Great Viscosity Race student packet and Viscosity Assessment (1 of each per student) 8) Test stopwatches 9) Prepare sentence strips 10) Find on-line videos of volcanic 1) Copy and laminate volcano photos 2) Cut cord and provide straws 3) Gather 10” balloons and digital scale 4) Gather full and empty soda cans, bottle of fizzy water, liter of Diet Coke, Mentos, tubing, and card 5) Gather hot plate, shallow pan, ice, water latitude, longitude, subduction, Ring of Fire, plate boundary, divergent, convergent, transform, bathymetric viscosity, viscous, magma, stratovolcano, shield volcano, cinder cone, thick, thin, sticky, runny, stiff Plate tectonics, explosivity index, subduction zones, stratovolcano, shield volcano, mid-ocean ridges, balanced and Lesson Parts Class time Lesson Objectives time to spare 5. Make predictions about the sudden release of pressure in several containers of liquid, and document their observations. Prep Time Lesson Preparation Key Vocabulary 6) Ready technology for showing videos Copy Volcanoes 5 documents – 1 per st unbalanced forces, high pressure, low pressure mass, weight, volume 1) Plate tectonics explosivity index subduction zones stratovolcano mid-ocean ridges balanced and unbalanced forces magma, lava, silica gas pressure, latitude, longitude 6. Students use formulas to calculate atmospheric pressures. 5b Building a Virtual Volcano 1 50minute period 1. 2. 3. 4. Option Modeling Volcanoes from a Multicultural Perspective 2 week research and technolo gy project 1. 2. 3. 4. 5. Both viscosity of magma and gas content are factors which determine characteristics of volcano eruptions. Write predictions, observations and conclusions about high & low pressure and depressurization. Predict shape of volcano based on silica & gas content. Connect location of volcanoes on tectonics plates with volcano type. Research active volcanoes using books, news articles, and websites. Synthesize unit content and connect with eruptive history an active volcano. Research indigenous myths associated with natural phenomena and why they might be useful to scientists. Use standard MS Office apps to produce brochure. Engineer 3-D working volcano model, incl eruptions characteristics consistent with research results. 30 min 2) 2 hours 1) 2) 3) 4) 5) 6) Reserve computer lab, and verify website and application run on available hardware and operating system. Copy Volcano 5b document “Volcano Explorer Student Worksheet” – 1 per st Reserve computer lab Determine students groups and distribution of research topics Reserve school or public library, or check out books to bring to the classroom Copy Volcano Project and Rubric, 1 per st Prepare technology to show slide show Prepare technology to demonstrate valuable websites
