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

Forces of Nature
• National Geographic Website
http://www.nationalgeographic.com/forcesofn
ature/
• Enjoy the volcano section
• You can take a quiz online at
http://www.nationalgeographic.com/ngkids/01
06/volcano/
• In groups, develop worksheet ideas for
student use when visiting this site
May ‘07 Eruption in Chile
http://www.nytimes.com/2008/08/10/world/americas/10chile.html
How Do These Compare?
• Aleutian Islands: Listen to Podcast
• Last one of 8/7/08 Kasatochi, third in three
weeks
• Chilean mountain erupted in May 2008
• Hawaiian Islands are always cooking

What’s an e-Mission™
• Video conferencing environment
• Challenger Learning Center
• www.e-missions.net
• Mission control is in charge
• Online materials for students and teachers
• Several award-winning missions available
for grades 3-12
Operation Montserrat
• Middle school students
• Will the volcano erupt? 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

• 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
