Lesson Plan 1: Evacuating a Volcano: A Simulation

Goal: To explore hazards associated with cataclysmic natural events, and human responses to them.

Objectives: Students will

  1. Work cooperatively in small groups to solve a problem;
  2. Consider ways of minimizing risk and threats to human safety;
  3. Identify behaviors appropriate in an emergency situation;
  4. Plan an orderly, step-by-step process in a limited amount of time;
  5. Evaluate their own group decision-making processes.

Concept: Cataclysmic events create threats to individual safety that must be analyzed and managed logically, methodically, and cooperatively.

Summary: Students imagine themselves staying for the weekend in a summer cabin near Mount St. Helens (or some other volcanic site), and having to quickly evacuate the area. Working in groups of three to six, they decide on the location of their cabin in relation to the mountain, and plan an evacuation procedure on a 30-minute timeline. Groups attempt to solve this problem cooperatively. Students then evaluate their groups' success, analyzing and discussing processes used to establish priorities, make plans and decisions, manage time and achieve consensus.

Content Areas: Social studies, language arts, science, group process skills. Group's task may be simplified for younger students; for older students, it may be preceded or accompanied by specific instruction in such group-process skills as consensus-building, decision-making, conflict resolution, etc.

Materials Needed for Evacuation Lesson:

Instructional Sequence:

  1. Divide students into groups of three to six members each. Provide each group with one copy of the Anywhere Recreation Area map. Group begins by deciding upon the location of their summer cabin, l isting at least three reasons for their choice. Emphasize that they must all agree on the location and the criteria for choosing it. Once they have decided, they should draw their cabin on the map.
  2. Ask students to imagine themselves in the Evacuation Scenario given below. Read it aloud to the class. (For dramatic effect, you may want to show the film or video version of "A Place in Time" or some other volcano video).
  3. Explain that it is now 7:30 a.m., and the groups have only 30 minutes in which to plan their evacuation. They must decide upon a plan that uses the resources they have available, and gets them out of the area in the least possible time. Emphasize that every member of the group must agree to the plan. Their resources include:
  4. It will be helpful to provide the groups with instruction in the following problem-solving process. (When students have agreed upon and completed the plan of action, they may consider themselves "evacuated". Have each group record the time it took them to complete the task.)
  5. After thirty minutes, find out which groups made it out in time and which did not. Record their times on the blackboard. Allow time for each group to share its plan. Encourage comments on the plans from other students.
  6. Have students discuss in their groups the following questions:
  7. Conduct a whole-class discussion. Provide opportunity for students to see how those in other groups made decisions, resolved conflicts, etc.
  8. Provide closure. Explain that volcanic activity can be seen as destructive when you think about its impact on the landscape, bridges, home, highways, wildlife and people. However, as they continue this unit their study will focus on another side of volcanic eruptions: volcanic forces as part of a natural earth-building process.

    Extension:

  9. Provide original groups with butcher paper and colored marking pens. As a lead-in to further work with this unit, direct them to brainstorm what they already know about volcanoes and volcanic eruptions. If they are unsure of their information, or a s they have questions, have them circle those items in their brainstorming list. After ten minutes or so, have groups share with the class their questions and needs for additional information about the topic.
  10. Post a composite list of questions in the classroom, so that you can refer back to them as the unit progresses. Unanswered questions can also be the starting points for students' final independent projects.

Evacuation Scenario:

It is a beautiful weekend in late Spring, and you have permission to spend it in a cabin owned by your friend Pat's parents, located near (Mount St. Helens or other volcanic site.) Until they return to pick you up on Sunday evening, you are "on your own" in the wilderness. You and your friends have spent your first day fishing and swimming in a nearby river, scouting the trails for a hike you plan to take tomorrow, eating, laughing, and generally having a wonderful time. By evening you are all exhausted, ready for dinner and an early bedtime. But one member of the group, Rudy, can't sleep. His restless movements around the cabin keep disturbing your dreams, and the others are complaining that he's keeping them awake, too. By dawn, your sleepless friend is up, crashing around the kitchen, fixing breakfast. Groaning and grumpy, everyone is awake by 6:30 a.m. It is May 18, 1980.

While the group eats, Rudy tells you all about the dreams that kept waking and upsetting him last night. He dreamed of a series of earthquakes and violent volcanic eruptions. At first, you tease him about his fears. You've all lived in the shadow of this familiar mountain most of your lives. True, over the last year it has been showing increasing, mild activity; however, scientists have maintained that there is no present danger.

But Rudy insists that he has a "premonition", that the dreams were so vivid he believes they're a warning. He want to pack up the gear, and leave the area. His words are having an effect on the rest of you, who begin to look anxiously out the windows.

Just then, Pat burst through the cabin door. He'd gone to get a clear view of the mountain from a spot about 40 feet in front of the cabin, and now he urges the rest of you to come out and look. Something new is happening. Instead of the usual light-colored puff of steam, there is a huge dark-gray cloud hanging over the peak. And then, there is a slight tremor at your feet. And then, a stronger shaking that knocks a can of soup off a kitchen shelf, and causes several empty Styrofoam cups to roll off the table onto the floor.

Realizing that you should:
	1) stay together,
	2) decide on the best route out of the area, 
	3) above all, avoid panic, you gather around 
	   the kitchen table to plan your evacuation.
