Introduction

• Question: How much money would it take to run concrete for an airport?
• Background: An airport runway typicality needs six inches of concrete to be safe. In this lesson you will be using area to calculate for volume of concrete. based on this volume you will be able to figure out how much money it costs to run an airport in Oklahoma. Task will involve coming up with a strategy for best determining the volume of concrete, given the depth is six inches.
• Textbook resource: Holt Geometry pp. 224, 225, 226
• Time required: 30-45 minutes

  Prerequisites(s)

  • It would be helpful if you know the relationship between volume, area, and depth.
  • An understanding of how to calculate volume given length, width, height and/ or area is needed.

  Standards Addressed

  • S 2.1 - Draw and analyze 2- and 3-dimensional figures.
  • S 2.2 - Use properties of 2- and 3-dimensional figures to determine unknown values (e.g., given the perimeter/circumference, find the area).
  • S 2.3 - Compute length, perimeter or circumference, area, volume, and surface area of geometric figures with missing information and correctly identify the appropriate unit of measure of each.
  • S 2.4 - Use geometric tools (e.g., protractor, compass, straight edge) to construct a variety of figures.

  Instructions

  1. Accessing Project
     1. Download the resource Garfield County Satelite Image. (This will take quite a while, the file is very large) If possible, your teacher needs to download this file the day before and have it located where students may access it faster.
     2. Click the 'Extract all files' from the folder task menu on the left.
     3. Choose My Documents as the location to extract to, click finish when done.
     4. Download the Garfield Count Projects Resource
     5. Click the 'Extract all files' from the folder task menu on the left.
     6. Choose My Documents as the location to extract to, click finish when done.
     7. Click HERE for instructions on how to assemble the Garfield County Project.
     8. Once you have assembled the project, open the folder named Garfield Project.
     9. Open the fGIS program by pressing on the icon.
     10. Double click the "FGIS" folder and open the #6 file.
     11. Select the Measure project file, which should be listed in menu as an option.
     12. If this is your first time using fGIS, access the video Tour to get started.
     
     
  2. Lesson Instructions
     1. Locate the airport in Garfield county. The project file should automatically go to the airport.
     2. Enlarge the window and zoom in so the airport takes up most of the screen.
     3. Consider printing a hardcopy of the airport and use it to come up with a strategy for determining the area (see highlighted area) of concrete poured?
     4. Given that runways should be at least 6 inches deep, determine the volume of concrete required to pour the airport. Recall there are 12 inches in 1 foot or 6 inches is 0.5 ft deep.
     5. Assuming a concrete truck can haul nine cubic yards of concrete, determine the number of truck loads required to pour the airport.
     6. Given the going rate per cubic yard is 76 dollars, how much would it cost the city to pour the airport?
