Hurricane Georges: An Interdisciplinary
Lesson
(Published in the TechEdge, 1998-99)
by Wesley A. Fryer
www.wesfryer.com
During late September, 1998,
hurricane Georges cut a path of destruction through heart of the
Caribbean and the Gulf coast of the United States. Over three
hundred people living on Caribbean islands were killed by the storm.
Its strong winds, heavy rains, storm surge, and tornadoes resulted in
an estimated two billion dollars in damage on the island of Puerto
Rico alone. Thanks to advances in meteorological technology and the
communication potential of the internet, events like hurricane
Georges provide opportunities for integrated classroom learning about
dramatic current events. This article provides detailed instructions
for teaching a multi-day classroom lesson about Hurricane Georges
using computers and internet resources as tools in the learning
process. A copy of this article, including links to all referenced
resources, is available online at www.wtvi.com/teks.
Integrated Learning is the
Best
It is unfortunate that today in
Texas, because of the tremendous pressure to help students succeed on
the Texas Assessment of Academic Skills, fewer teachers have time to
present integrated, thematic lessons. Research shows that students
learn best when knowledge and skills are presented contextually
rather than in isolation. By choosing a topic like Hurricane Georges
for class instruction, a wide variety of skills and concepts in
different subject areas can be explored simultaneously.
In the December 1960 issue of The
Mathematics Teacher, Jerome Bruner observed "Teaching children to
think is most difficult. We know that education does not take place
without thought and without encouraging further thought. We also know
that further thought about any topic will exist only to the degree
that one possesses a favorable disposition toward that topic, idea,
or subject." When teachers use internet resources to focus on an
exciting topic like tropical storms, students get excited. They ask
questions which go beyond the scope of the planned lesson. They
acquire knowledge and skills in math, science, reading, and social
studies, without ever realizing they are "doing work" in a particular
content area. Perhaps most important, as Bruner noted, students get
excited about the learning process itself and engage in critical
thinking.
Materials
This lesson can be presented either
in a classroom setting with a single computer (or "garden" of
computers), or taught in a lab where each student has access to
his/her own computer. The minimal requirements include:
- A computer (Mac LCIII / 486 PC or
newer)
- A web browser (Netscape, version
2.02 if it's running on an older computer)
- WebWhacked sites (downloaded
internet websites copied onto your computer's hard drive -
www.bluesquirrel.com/whacker)
- Copies of the student instruction
sheet and tracking map (1 per student)
It is important to note that a
classroom phone line, network wiring connection, or other connection
to the internet is NOT required. Using WebWhacker software, internet
content can be downloaded at home or in the computer lab and
transferred to a computer in the classroom. For more information
about WebWhacker, refer to the article "Offline Web Browsing = No
More Excuses" at www.wtvi.com/teks/article4.html
or the workshop "Internet Research in the Classroom: Online and
Offline" at www.wtvi.com/offline.
If available, several other materials
are helpful. The teacher can use a television, VCR, and recorded
news reports or video coverage of a hurricane's damaging effects to
introduce the lesson. If an AverKey or other scan converter is
available to display the computer screen on the television, the class
can view satellite images, news photos, graphs, and other multimedia
elements during the lesson more easily from their seats. Students
can complete the basic lesson requirements with a pencil and their
handout. The optimal situation, however, is for students
(individually or with a partner) to transfer their written answers
and map drawing into a digital computer document. The ClarisWorks
drawing environment works well for this purpose on both Macintosh and
Windows computers.
Objectives
The purpose of this lesson is to
motivate students to learn a wide variety of information about
tropical storms and extend their understanding of the scientific
relationships of meteorology. While learning these concepts,
students exercise a variety of reading skills and demonstrate
mastery of numerous mathematics, social studies, and science skills.
Additionally, if equipment is available, students can utilize
computer technology to find information and incorporate it (in both
textual and graphic forms) into a word processing document or
multimedia presentation. The overarching purpose of this lesson is
to encourage students to embrace an attitude of inquiry relating to
meteorology and tropical storms, which will lead to personal
discoveries and learning experiences which go beyond the stated
objectives of the lesson.
If students have the opportunity to
put their answers into a computer document, some of the specific
TEKS
for Technology addressed by
this lesson include:
- §126.2.b.4-5 The student
uses a variety of strategies to acquire information from
electronic resources, with appropriate supervision...acquires
electronic information in a variety of formats... including text,
audio, video, and graphics.
- §126.2.b.7.B Use
appropriate software, including the use of word processing and
multimedia, to express ideas and solve problems.
- §126.12.c.7.G Integrate two
or more productivity tools into a document including, but not
limited to, tables, charts and graphs, graphics from paint or draw
programs.....
Introducing the Lesson
Videotaped news coverage of hurricane
Georges, or any other powerful hurricane, provides an excellent
introduction to this lesson. If you do not have access to videotapes
of hurricanes or do not have an opportunity to tape a segment
yourself from the evening news or the Weather Channel, short video
clips are available to download from the internet. Visit
www.cnn.com/video_vault/explore
and search the video archive for the keyword "hurricane." This
simple search yields over 100 different movie clips in varying
formats. To search for only Quicktime movies (or another specific
file format), click on "Expanded Search" (http://magnifi.cnn.com/powersearch.html)
and check only those file formats you want to find. For tips on
downloading and presenting Quicktime movies , see www.wtvi.com/teks/article6.html.
One
of the most popular sites for obtaining information about current
events is the Cable News Network's site, CNN Interactive
(www.cnn.com).
In the case of a Caribbean hurricane, however, better news coverage
is often provided by international sources. The site "El Nuevo Dia
Interactivo" (www.endi.com)
is the Puerto Rican equivalent of CNN in Spanish. Whether or not you
have Spanish language skills, this website can provide your classroom
with a wealth of multimedia resources on Caribbean current events.
Additionally, it can provide an eye opening experience for students
to the international nature of the internet. The link to
"Galería fotográfica del huracán" (Photographic
Gallery of the Hurricane) on the ENDI homepage in late September,
1998, contained numerous, dramatic photos of hurricane damage,
including the accompanying photograph of a severed highway bridge
near the Arecibo radio telescope. Due to the dynamic nature of a
website like endi.com or cnn.com, however, information about
hurricane Georges may not be available there when you decide to teach
this lesson. If you do not have success finding images at either of
these websites, use the resources mirrored at www.wtvi.com/teks/hurricane.
The introduction to this lesson
provides an ideal time to review place location geography skills with
students. Reviewing the locations of continents, oceans, and the
islands in the Caribbean is a good place to start. Longitude and
latitude should also be discussed. Next, ask students where they
think hurricanes are born, or spawn. The Federal Emergency
Management Agency website (www.fema.gov)
includes a link to a page which answers this question. The color
coded map of hurricane tracks for 1998 (www.fema.gov/hu98/tracks98.gif)
shows that hurricanes affecting the eastern and southern United
States form off the coast of Africa. Students looking at that map
can see how some hurricanes veer north and lose their energy, while
others head toward the US only to turn abruptly east. Students can
also see how some hurricanes, like Georges, plow west across the
Caribbean and over the United States, possibly even dropping large
amounts of rain on their own hometown. Additional information about
hurricane origins is available from The Weather Channel online at
http://www.weather.com/breaking_weather/encyclopedia/tropical/origins.html.
FEMA's Tropical Storm Watch page (www.fema.gov/fema/trop.htm)
is also a useful resource.
Lesson Steps
After introducing the lesson, pass
out a copy of the project instruction sheet to each student. First,
students should use the data contained in the table to plot nine
points on the path of hurricane Georges in the Caribbean. Instruct
students to round longitude and latitude measurements to the nearest
whole number, and review the rounding process. As a technique for
plotting, have students sketch a light line across their page on the
appropriate parallel (latitude line), and a light, vertical line
along the meridian (longitude line). Have students draw an "X" or
large dot on the intersection of these two lines. This instructional
technique was effective with fourth, fifth, and sixth grade students.
Older students may need less guidance. If they are struggling,
however, allow students to pair up and work collaboratively on this
project. After you have graphed three points together as a class,
have students continue the plotting process independently.
Once students have successfully
plotted the path of hurricane Georges on their paper, they can
replicate the track on the computer. If you are teaching this lesson
in a one computer classroom or another situation where it is not
practical for every student to utilize a computer, you can choose to
complete these next steps together.
Prior to the lesson, insert the
hurricane tracking chart created by NOAA (www.citi-net.com/george/tropical/images/htrkchrt.gif)
into a ClarisWorks drawing document or other word processor that
includes drawing tools. Rather than reduce the image to fit on a
single page (in landscape, not portrait orientation), move the map so
the longitude and latitude axis scales are visible on the bottom and
right edges of the page. Have students use the circle and line tools
from the drawing toolbar to plot the track of Georges across the
Caribbean, as shown in the accompanying illustration.
After
students complete their digital hurricane plot, have them answer
questions two through six using internet websites and multimedia
CD-ROM encyclopedias. To facilitate this process, you can either
link to or WebWhack (two levels deep) the following webpage:
www.wtvi.com/teks/hurricane/georges.html.
This webpage contains all the links students will need to answer the
questions on their project instruction sheet. You may consider
adding your own questions to this list. An online copy of the
instruction sheet is available at www.wtvi.com/teks/hurricane/handout.html,
which you can print or copy and paste into your own word processing
document to make modifications as appropriate.
In addition to the websites already
listed, the National Oceanic and Atmospheric Administration's (NOAA)
Geostationary Satellite Server (www.goes.noaa.gov)
is a fantastic repository of current and archived satellite photos.
The GOES satellites are the geosynchronous satellites that the United
States government maintains over each coast. Technically speaking,
"a geosynchronous orbit is one that has the same orbital period as
the Earth's sidereal rotation (23 h 56 m 4 sec), but does not have an
orbital inclination and eccentricity of zero" (www.astro.virginia.edu/~eww6n/physics/GeosynchronousOrbit.html).
In layman's terms, this means that the satellite's continuous fall
toward earth (its orbit) is in perfect sync with our planet's
rotation. GOES 8 is the satellite over the east coast, GOES 10 is
over the west coast. From the GOES image search browser, you can
download any image from either satellite from the past twenty-one
days. The search interface allows you to specify the date and time
of the photo, as well as the type (visible or infrared). This
website is a tremendous resource! Since photos of hurricane Georges
may not be available when you choose to teach this lesson, copies of
several GOES images are available at www.wtvi.com/teks/hurricane/georges.html.
Use of GOES satellite imagery will
naturally introduce the concept of GMT (Greenwich Mean Time), also
called "Zulu time," into your classroom. As part of the project
activities, students will learn about this standardized time used by
pilots, meteorologists, truck drivers, and UPS delivery men. They
will also learn how to convert their local time into GMT, and vice
versa.
While this lesson can be taught in a
variety of settings and with students of different grades, it was
originally designed as a computer lab lesson to be taught during
three weeks. During that period, students came to the computer lab
for three forty-five minute lessons.
Curriculum Links
The best time to teach a lesson about
hurricanes is during hurricane season. What time of year is that for
the United States? The fifth question on the student instruction
sheet asks just that question. A graph on the FEMA website
(www.fema.gov/hu97/strmfrm.htm)
provides the answer: August through October. Whether you choose to
teach a lesson on hurricanes during these months or not, students can
benefit tremendously from the knowledge and skills they gain in a
variety of content areas. These benefits go well beyond the
geographically oriented purposes for this project.
In the area of mathematics, this
lesson teaches students how to plot points on a coordinate grid
system. They are required to successfully round longitude and
latitude measurements to the nearest whole number. Students learn
about measuring wind speed in knots and air pressure in millibars.
They additionally interpret data contained in graphs and could even
construct their own graphs with gathered data as an extension
activity.
Students practice a variety of
reading skills during this lesson as well. Students are required to
summarize information, interpret data contained in a table, make
generalizations, and determine the main idea of a passage. Students
must draw inferences from textual information and write sentences
which support these conclusions with evidence from the
text.
Social studies skills embedded in
this lesson include an understanding of longitude and latitude and
the ability to plot points on a map. Students learn how to use
geographic tools to collect, analyze, and interpret data. They
review place location (names and locations of
continents/oceans/islands) and are further exposed to the concepts of
time zones and time conversion.
As the stated purposes of this lesson
indicate, it is principally focused on helping students understand
scientific concepts and relationships. Students learn about the
development and life of tropical storms and hurricanes, geostationary
satellite orbits, and concepts of air pressure and wind
speed.
This list of student knowledge and
skills is only partial. Additional directions the lesson takes are
up to you and your students to determine!
Can you say "TAAS
Objectives?"
After reading over the previous list
of curriculum links, Texas teachers can quickly recognize that
virtually all of these skills and concepts correspond to objectives
of the Texas Assessment of Academic Skills (TAAS). Rather than
presenting TAAS skills in isolation, however, this lesson takes an
integrated approach which is more motivational and simply more fun
for students and teachers alike.
This lesson epitomizes the philosophy
that technology is not the "end" of classroom instruction, it is
merely one of the "means" of making that instruction more exciting
and effective. Whether your lesson is about hurricane Georges or a
different topic, technology can open doors of instructional
opportunity for you and your students that would have been impossible
just five years ago. The potential for this type of classroom
instruction is available to every one of us: our challenge is to
obtain the tools and knowledge required to realize that potential in
our classrooms!
