The Volcanoes of Io
An interactive exercise enlisting students
In addition to learning about Kilauea volcano in Hawai'i, students
will also learn how Dr. John Spencer views volcanoes on Jupiter's moon Io. During
the broadcast, students will see digital pictures of Io from the
Telescope Facility on Mauna Kea, Hawai'i. These pictures, produced by a
camera behind the telescope, will be sent by the Internet to the broadcast
site. Watching Io's brightness change as it rotates will tell us where
the volcanoes are. The brightness values will be included with the pictures so that students can create a "map" of volcanic activity on Io when they return to the classroom.
Paul Varsho, one of the Teacher Argonauts has sent a message to the jason-teach discussion
group explaining in more detail how to use the Io Light Curve data provided by Dr. John
Spencer. You can read his explanation by clicking here and get the most current lightcurve data from Dr. Spencer.
Dr. Spencer's exercise will be carried out in two parts:
The real-time exercise where students will look at a single,
ideally real-time, image to locate the volcano on Io. Instructions on
how to conduct this exercise and all the required images of Io can be found HERE
The off-line exercise where students access the data on the
brightness of Io all around its orbit, gathered over a week or
so, in order to determine where the volcanos on Io are.
