Classroom sessions/estimated time: Three Class Periods, 50 minutes each
Grade Level(s): 9-12
Purpose: To explore the impact of remote sensing as it relates to the discovery of the Lost City of Arabia
Geography Standards addressed:
National Geography Standards addressed:
Essential Element 1: the World in Spatial Terms
Standard 1: How to use maps and other geographic representations, tools and technologies to acquire, process, and report information from a special perspective
Essential Element 6: the Uses of Geography
Standard 17: How to apply geography to interpret the past
Indiana Geography Standards addressed:
Standard 1: The World in Spatial Terms
Students will use maps, globes, atlases, and grid-reference technologies, such as remote sensing, GIS, and GPS to acquire and process information about people, places, and environments.
Standard 2: Places and Regions
Students will acquire a framework for thinking geographically, including the location and unique characteristics of places, They will identify the physical and human characteristics of place.
Standard 6: The Uses of Geography
Students will understand the influence of physical and human geographic factors on the evolution of significant historic events and movements. They will apply the geographic viewpoint to local, regional, and world policies and problems.
Some students may need additional time to complete the research from the preceding day. Allow time for class discussion and to discuss any problems they are having finding the material. After the students have some background information on the lost city of Arabia (both through research and teacher presentation), ask the question "How was this city, which was lost for thousands of years, discovered?"
To demonstrate the difficulty in locating the lost city, pour a bag of sand containing one pellet of metal into an oblong container. Explain to the students that there is a small pellet of metal (metal shavings will work also) located within the sand. Allow several students to try to find the metal. (This will be a daunting task!) Keep the sand in the classroom for the students to continue exploring. It will also be used on the last day of the lesson.
Relate the activity to the great difficulty archeologists faced in trying to discover a legendary city in miles and miles of sand dunes, which reached 1000 feet in height in some areas. Open website http://courses.smsu.edu/ejm893f/creative/glg110/deserts-wind.html#backstardune. Click on the photographs to enlarge them.
After discussing the lack of landmarks within the photographs, probe students regarding shifting of locations due to weather conditions. Lead them to discover that the shifting of the sand makes it nearly impossible to pinpoint specific locations for later use.
Activity : (This is a computer
simulation that informs about tools needed to find out where they are.)
This could be done by individual students assigned to computers or does as a class using a projector system. Open website http://www.pbs.org/wgbh/nova/ubar/hotscienceubar/index.html. This website asks students to imagine that they are archeologists looking for the lost city of Arabia. Their first task is to locate the Rub al Khali Desert by clicking on its location on a world map. A wrong click identifies the desert that they have found and also gives directions (Try heading southwest.) for locating the Rub al Khali. When the students click on the correct location, they are given factual information on the Arabian Desert and presented with the task of selecting items they will need to help them figure out where they are. As students select three of the six items (teddy bear, map, compass, fire, whistle, and global positioning system receiver) an explanation on the items usefulness is given.
Conclusion: Class discussion of focus question "What role did remote sensing play in the discovery of the lost city of Arabia?". Emphasize the collaboration between archeologists and scientists who utilize remote sensing as the major reason the lost city of Arabia was located. (Findings that should be identified include locating distinct tracks through the desert, which were identified as old caravan routes, the imagery allowed the archeologists to look at a large area in a single scene further allowing them to analyze vast portions of the desert at one time, using image processing techniques to highlight important features and data from different sources allowed them to exclude large regions of the desert and narrow the search to the most promising sites. Types of remote sensing identified should include radar imaging, Landsat imagery, and Thematic Mapper. To demonstrate the usefulness of remote sensing, provide students with a bar magnet and ask them to find the pellet of metal (or metal shavings) in the sand. This may take a few minutes but is a much, more efficient way of locating the metal. Relate this to remote sensing's ability to help archeologist become more efficient in their quest to uncover the past.
