Lab 9: Death and Destruction
The lab activity described here was created by LuAnn Dahlman of TERC for the EarthLabs project.
Summary and Learning Objectives
Students search for images and video that illustrate the dangers that hurricanes pose to property and life. They consult Morbidity and Mortality Reports to find the common causes of death attributed to hurricanes and to discover the challenges to counting deaths attributed to Hurricane Katrina in 2005. Students explore hazards from storm surge, high winds, and inland flooding and outline a plan that would prepare them to survive a hurricane.
After completing this investigation, students will be able to:
- describe the dangers to life and property posed by hurricanes;
- interpret reports to list common causes of death attributed to hurricanes;
- explain the difficulties in making an accurate count of deaths attributed to Hurricane Katrina;
- interpret the graphical results of a computer model of a storm surge and compare it to a simple physical model;
- prepare an outline for being prepared to safely survive a hurricane.
Context for Use
This lab could be completed any time within the hurricane sequence. It could be assigned to pairs of students in a computer lab or as homework if students have sufficient Internet connectivity. Alternatively, the lab could be presented using one computer with a projector, complemented by hard copies of the reports that students read. An optional hands-on activity requires awareness of safety issues related to electricity and water; the activity could be shown as a demonstration or omitted.
Activity Overview and Teaching Materials
In Part A, students search for photos and videos of hurricane damage. Links to known sources of these resources are posted in the student activity. Students also skim reports from the Centers for Disease Control: they consult the Morbidity and Mortality Weekly Reports for Hurricane Charley, Hurricane Floyd, and Hurricane Katrina. They also access reports of the deadliest and costliest hurricanes and consider factors that affect these statistics.

Teaching Notes and Tips
It is a good idea to enforce a strict time limit on the searching for hurricane photos and videos, or students may spend all their time on that task. By asking them to choose a favorite or two of the ones they've seen, you'll come up with a list of good links that you can post.
The Morbidity and Mortality Reports may be upsetting to some students. While the content is not gory or sensationalized, the topic is still death. Use your best judgment to prepare your students appropriately for this assignment.
In Part B, the first section on Storm Surge, step 1 has student view a diagram and animation of a storm surge. Several of the animations in the document are still in Flash format on the site and can no longer be watched online. The video versions are embedded in the Lab for step 2.
You can assess student understanding of topics addressed in this Investigation by grading their responses to the Stop and Think Questions.
State and National Science Teaching Standards
If you're working with older students, this video with information about what driving through floodwater can do to a car may be interesting to them.
