Volcanoes & Videoconferencing Challenger E-Mission Prep Lynne M. Bailey CSD 9 Title IIB STEM Grant [email protected] or [email protected] Agenda • Paperwork • Introduction • Protocols • Objectives • Review volcanoes • Prepare materials for e-mission team • Activities • Forces of Nature website • E-Mission practice • Volcano bursts • VC Providers • Reflection • Share-out Online Agenda & Links • http://teacherlynneb.googlepages.com • Click on Workshop Agendas • Click on today’s subject • Read the hand-out on Volcanoes from Challenger’s e-mission Getting Started • Paperwork done? • Protocols – leave no tracks! • Earth science components • Volcanoes • Hurricane • Algebraic calculations • Mapping • Disaster planning Volcanology What’s Hot? Volcano Primer • Escape of hot, molten rock (Magma), ash and gas through planetary crust from below the surface • Creates an opening, or rupture in the crust • Magma is called lava as it flows out and can form mountains or features like mountains over a period of time • Heat rises because hot substances are less dense than colder ones; this heat energy and trapped gas can create cataclysmic explosions • Most formed at subduction zones found at tectonic plate borders Volcano Types • Shield volcano • Oldest form, tall and broad with flat, roundish shapes: Olympus Mons on Mars, Kilauea • Cinder cone volcano • Small cone-shaped: Crater Lake • Composite or stratovolcanoes: majestic, towering like Mt. St. Helens Stratovolcano Cross-Section 1. 2. 3. 4. 5. 6. 7. Large magma chamber Bedrock Conduit (pipe) Base Sill Branch pipe Layers of ash emitted by the volcano 8. Flank 9.

Will a nearby hurricane make landfall? • Should you evacuate residents from their homes? • Simulation based on real-life events on Montserrat • Computers with Internet access and VC equipment required Four Teams • Soufriere Hills volcano on Montserrat is ready to erupt at the same time a Category 3 hurricane is approaching • Volcano team calculates rock fall and volcanic tectonic data to predict volcanic activity • Hurricane team tracks hurricane and estimated estimates path and arrival time • Evacuation team uses population maps and transport options to move residents from danger zones to safe shelters • Satellite data from the island transmitted every 56 minutes • Communication team keeps Mission Control informed and relays team recommendations Previously… • Overview presentation • Visit website and review materials • www.e-missions.net • Operation Montserrat – for students: T-3 Weeks • http://www.emissions.net/om/3weeks/yourTask.aspx • See teacher site for sequence & task plan Connect to Mission Control Can use webcam with Safari Check with Rosemary Nieves, Grant Coordinator/ NYIT for additional resources Today’s Mission: Volcano Team • Distribute volcano team worksheets • Complete in groups • Review volcanic eruption data and graphs • Rock fall • Tectonic activity Construct a Volcano • Research ideas for volcano designs • Experiment with bursts • Alka Seltzer in small containers • Baking soda and vinegar • Menthos and Coca Cola? (see YouTube for videos) • Add to wiki page at http://technoed.wikispaces.com Bursting Gas Alka Seltzer Experiment • Need: Alka seltzer, film canister, or similar, water & pushpin • Develop hypothesis • Put 20 mm water (about 4 tsp.) into canister • Add ¼ Alka seltzer, cover and observe • Repeat, adding ½ a tab, cover and observe • Repeat again, but this time, put a few small holes in canister lid. Add ½ a tab, cover with lid and observe. • Write up your experiment: Hypothesis, materials, procedure, results & conclusion Vinegar & Baking Soda • Need: Aluminum tray, Large cup, small Dixie cup, food coloring • Place large cup upside down in pan • Add baking soda to Dixie cup to about 1/3 and place on top of large cup • Add white vinegar tinted with food coloring? and stand back • Variations: • http://www.volcanolive.c om/model.html From PS 53 Online Volcano Resources • This presentation and resources are online at http://technoed.wikispaces.com Click on the Volcano tab Video Conferencing • Joys • Very engaging • Great pre & post-conferencing resources • Pitfalls • Equipment • Expense • Coordinating VC Providers • NASA • Many museums • For video conferencing providers go to http://www.nyiteez.org/providers.htm VC Equipment • Traditional • New • Webcam attached to interactive white board • Online server connection • www.safarimontage.com • www.sightspeed.com • Video support via Skype, Yahoo, Aim, Reflections Reflection and Share -out • Written reflection of today’s workshop or • Add a comment to the blog http://lynnembailey.edublogs.org Closing • Questions • Evaluations • Check the blog for these and more resources • Pictures will be posted and linked to http://flickr.com/photos/lynnemb/ for more photos Thanks for Coming!
