Learners study topographic maps and contour lines and construct a simple three-dimensional model of Mount St. Helens before the May 18, 1980, eruption. They use topographic map skills to interpret the impact of the May 18, 1980, eruption...

Students observe two demonstrations to conclude why bulge developed on the north flank of Mount St. Helens and conclude that when the "cap" was removed the pressure inside the volcano was suddenly released causing the violent eruption.

Learners review previous lessons about volcanoes and name the phenomena they think the eyewitnesses of the Mount St. Helens witnessed. They play the roles of reporter, eyewitness and scientists who are serving on a committee...

Students compile information on volcanic activity at Mount St. Helens.  In this earth science lesson, students use the information they gathered on Mount St. Helens to answer questions and create charts in Excel.  Then students...

Students discover that volcanic eruptions are geologic events that take place within the upper part and on the surface of the Earth's lithosphere. They explain how volcanoes are related to the Earth's lithosphere. They focus on the May...

Students create a legend that explains the existence of Mount St. Helens. They discuss how natural occurences often have no clear explanation. After listening to legends concerning the formation of Mt. St. Helens, students create their...

Students research volcano hazards in VolcanoWorld, make a paper volcano, produce and watch the effects of ashfall, produce and watch the effects of a mudflow and create a hazard map by plotting historical ashfall/mudflow data from Mount...

Students become familiar with Native American myths and legends created to explain volcanic activity. They apply the clustering, writing process and peer-editing techniques to the writing of an original myth about Mount St. Helens

Students investigate the concepts related to volcanoes and focus upon Mt. St. Helens. They define the difference between an active and dormant volcano. They conduct research using a variety of resources. The information is used in order...

Students become familiar with an eruptive history and related world events and impart a sense of the immensity of geological time. They explore timelines by creating their own, then are introduced to major eruptive periods of Mount St....

In this Mt. Saint Helens worksheet, students read the passage about Mt. Saint Helens and answer true or false questions. Students answer 10 questions. 

Learners use clustering/mind mapping techniques to generate ideas, graphically represent inferences, organize their conclusions and write a report that presents conclusions the writer has reached, and facts substantiating those conclusions.

Students utilizing a volcanic hazard map of Mount Rainier, reach conclusions about the potential hazards of future eruptions. They create educational materials about these hazards and what to do if one erupts again in the future.

Students imagine themselves staying for the weekend in a summer cabin near Mount St. Helens (or other volcanic site,) and having to quickly evacuate the area.

Students prepare for a field trip to Mount St. Helens National Volcanic Monument and exploration of Ape Cave (see also Ape Cave Exploration). In the absence of a field trip, students become acquainted with lava tubes in general.

Students evaluate the impact of volcanic ash on the surroundin environment. Through discussion, videos and activities, they identify the various ways in which volcanic ash can be more detrimental than volcanic magma and lava.

Students conduct research and teach each other about the eruption of Mount St. Helens and identify the major components of the eruption, their characteristics and their effects. They simulate the eruption dramatically.

Students construct a mockup of a volcano by crumbling up newspapers and piling them into the shape of a volcano. They place a tarp over the newspapers making sure the tarp is large enough to simulate a flat area at the volcano's base....

Students create models of the three major types of volcanoes and determine how a volcano's shape is related to the type of material erupted. They then observe a demonstration that simulates the nature of two volcanic materials: lava and...

Young scholars watch a demonstration to introduce them to the consistency of mudflows and how they move. In groups, they compare and contrast volcanic avalanches and mudflows. They create their own model of a volcano, simulate how it...

Students discover the various ways in which tree rings can give information. After a brief disucssion of concentric tree rings, they use cross section cut outs of tree rings to identify the time and type of various naturally occuring...

Pupils, while utilizing a large wall map, experiment recording the annual precipitation for cities on the east and west sides of the Cascade Mountains. They discover that volcanic mountains do not have to erupt to affect the atmosphere.

For this Plinian eruptions worksheet, students read about the types of volcanic eruptions and about Gaius Plinius Secundus who the Plinian eruption was named after. Students answer four critical thinking questions about volcanic eruptions.
