Classroom Activity:

 

Living with Fire CD-ROM

What’s the Point? Fires have shaped the wildlands of North America for thousands of years, but fire has been excluded from many of these ecosystems for nearly a century. Does it matter? One of the consequences of fire exclusion, scientists believe, is a change in the fire behavior likely when a fire does finally occur–a change in the fire regime. In this activity, students play a simulation game to explore the effects of various management choices (treatments) on the behavior of a subsequent wildland fire in ponderosa pine/western larch/Douglas-fir forests. They use the CD-ROM Living with Fire, which displays data from mathematical models of tree growth and fire spread in a "cartoon forest" format, to make management choices and view the consequences. Living with Fire is limited to ponderosa pine/larch/Douglas-fir forests; students will not learn about other kinds of forest (for example, cedar/hemlock, grand fir, lodgepole pine, or whitebark pine) in this activity.

Living with Fire requires a computer with CD reader and Internet Explorer 4.0 or higher. The CD can be loaded on multiple computers. The activity can be done individually or by teams of two students. The teacher introduces the activity and assignment and then schedules students to use the computer and complete the work. Class discussion of results follows completion of the activity

Teacher’s Map:

Vocabulary: prescribed burn, surface fire, thin, treatment

Materials: You will need one copy of the Student Page, Living with Fire, for each student or team.

Procedure:

  1. Explain: The assignment will give students a taste of some of the choices that land owners, firefighters, and managers of public lands make when they work in forests where fire has been an important force. They will use the CD to answer questions.
  2. Explain your strategy, the schedule for computer use, and when the assignment is due.
  3. OPTIONAL: Explain the decision-making structure of the CD: First, an introductory section provides information they will need to make wise choices. Then they enter the game, make choices, and view consequences. The CD is organized with 5 levels of choice:
  1. Have students use the CD, complete the worksheet, and hand it in. Use for

    Evaluation.

Closure: Use a few minutes of class time to discuss:

1. What was the most severe ("scary?" "destructive?" "dramatic?") fire behavior found?

2. What conditions led to the severe fire behavior?

3. Were the game results always what you expected, or were there some surprises? Explain.

4. Were the results from your choices believable? What made the information on the CD believable… or not?

5. How important is scientific information to decisions like the ones used in this game? What other information is important for making those decisions?

Extension:

Assignment for discussion or writing project: The CD shows predictions for forests dominated in past centuries by ponderosa pine. What about lodgepole pine forests, whitebark pine forests, and the dozens of other kinds of wildlands that occur in your local area? Do library research, use the Fire Effects Information System (www.fs.fed.us/database/feis), and talk to local experts. Learn the effects of various kinds of forest treatment, including the use of no treatment at all, on potential fire behavior.
