A Little Help for Teachers… BACKGROUND INFORMATION: Realistic Points in the Movie - Depiction of enormous power released during a composite volcano eruption. - Explosive eruption with lots of tephra. - Hot springs exist near volcanic activity. - Towns water supply became contaminated. - Volcano became restless quickly (within one week of first signs of activity). Earthquakes do occur. - NASA tested a robot named Dante at volcanoes in Alaska and Antarctic. - Lakes near volcanoes can become acidic enough to be dangerous to people (pH of water was tested initially). - Seismograph readings. - Carbon dioxide can kill trees and wildlife. Unrealistic Points in the Movie - Can be deadly for helicopters to fly in areas with dense ash in the air. - Lava flows were too fluid! (looked like mafic magma). Should be thick and slow moving (Cascades = felsic). - Temperature of hot spring near volcano changes more slowly than shown (increase takes days, weeks to develop). - Water supply probably contaminated too quickly. - Earthquakes associated with eruptions rarely exceed 5.0 (not big enough to destroy houses, roads, and buildings). - Robots are not used by the USGS to monitor earthquakes. They rely on observations and measurements taken in the field and with satellites. - Unlikely that acid lake would dissolve the metal boat in minutes. - Seismographs were not real...patterns not reflective of earthquake shown. - Driving across lava flow! Whatever! 2000 degrees C! Rubber tires melt, gas tank ignites...
Examples of Student Questions for Rubber Ducky Article What was the main advantage of the ducks getting dumped into the ocean? a)To bump Princess Di off the front pages of British newspapers. b)To study ocean currents and wind currents. c)To study the climate. d)To study what weather has to do with oils spills. The toys were dumped into the ocean: a)Because people were angry. b)By a careless sailor. c)In a crazy, unexpected storm. d)As they were going onboard. A similar thing happened in 1990 when a) Barbie dolls went overboard….ahhhh! Splash! b) Nike shoes were lost at sea. c) Hot, new clothes made in Taiwan got knocked into the ocean. d)A years supply of dust rags disappeared from the ship. Weather patterns are very interrelated with: a) Pollution patterns b) Solar radiation patterns c) Ocean current patterns d) Fish migration patterns What is being used to track the plastic ducks, turtles, frogs and beavers? a) A computer model b) Aircraft and satellites flying over the region c) Small fishing boats using fish trackers d) Hunting dogs with flippers on…
Examples of Student Questions (Continued…) Which is false? A) The ducks were most recently on the beaches of Sitka and Kodiak B) Studying the ducks help scientists predict what salmon may do when they come back C) There were a total of 3,000 toys D)The toys needed no flotation devices Why did the toys need no flotation devices (as scientific instruments in the ocean would normally need)? Write a letter to the intended destination point for the toys explaining why all is not lost and how what happened will actually be good for their community and good for others…
