Science is a new way to teach middle school science. It is an
award-winning, standards-based program in which newsworthy events
establish the relevance of science topics; authentic tasks create the
need-to-know more about those topics; and lively interviews,
photographs, Web pages, and inquiry-based science activities create a
desire to know more about those topics.
Volcano! is an Event-Based
Science module about the dynamic forces that help to shape the surface
of the Earth. It uses the 1991 eruption of Mt. Pinatubo in the
Philippine Islands to establish the context for exploring concepts
related to volcanoes. The task in Volcano! places students in
the roles of producers of a television show about the risks to people
living at the foot of Mt. Rainier, in Washington. Students will acquire
then use their knowledge of plate tectonics, lava flows, debris flows,
and the Ring of Fire to assemble the seven segments that make up the
To enhance students'
enjoyment of this EBS module, there is an album of photographs for
students to use.
These photographs were
taken at Volcanoes National Park, Hawaii, Hawaii by Event-Based Science
(Click on this
photograph to open the album.)
As with all Event-Based
Science modules, much of the information that students need is provided
in the pages of Volcano!. However, more information is needed.
Information about current earthquakes and volcanoes will add to the
authenticity of your study. Information about the area around Mt.
Rainier will add to the urgency of the task.
Between 1995 and 2017 the Event-Based
Science website was available
free to all users. We want to continue making the site available free,
but to do that we need your help. We're hoping that small contributions
will provide the support we need to continue publishing.

There is a
problem with the answer key to Here Comes the Mud. On page 13
of the Teacher's Guide the estimated arrival times for the mudflows are
incorrect. They should be:
10 km/hr and
Auburn 3.6 hr
and .72 hr
hr and .8 hr
hr and .86 hr

Tracking a Volcano Piton de la Fournaise volcano is located in the Indian
Ocean more than 1,000 km east of Madagascar (21.2°S, 55.7°E). Piton de
la Fournaise typically erupts about once a year. The 2002 eruption
began on Saturday, January 5, at 11 p.m. local time and stopped at 7:10
p.m. local time on Wednesday, January 16.

Lahars Sweep Down the Muddy River,
Mount St. Helens Within the
first few minutes of the 18 May 1980 eruption of Mount St. Helens,
numerous lahars were generated on the west, south, and east flanks of
the volcano. One lahar originating on the upper east side of Mount St.
Helens flowed 30 km down the Muddy River into a large reservoir in less
than 30 minutes. At the base of the volcano, the Muddy River lahar
flowed as an unchannelized broad sheet as fast as 110 km/hour. As the
lahar flowed down the Muddy River valley, its velocity slowed to an
estimated 10 to 20 km/hour and its depth varied from 2 to 9 m. The
photographs on this page show some of the effects of the lahar as it
traveled down the river valley.

an Eruption Try your hand at
predicting an eruption of Mount St. Helens using data collected by
scientists of the USGS Cascades Volcano Observatory. This presentation
uses data from several eruptive episodes of Mount St. Helens in the
1980s to show the way in which a series of eruptions were accurately
predicted by USGS scientists as far as 3 weeks in advance.

volcanic eruptions and weather, was originally presented in 1784.
