Comparative Land Use Lab Activity

Avg. Ratings: 4.0 (1 Review)
Determine Consequences of Different Environmental Choices

  • Practice analyzing geospatial data
  • Linked to a real world scenario
Using two aerial photos — one from 1963 and one from 1991 — students take a scientific look at changes that have occurred in the 28 years between those dates. Using a transparency grid overlay, students count the number of blocks that cover different types of areas (e.g., manmade structures, forest, open land, water) on each photo. They will then create a pictorial grid of the area for each year, calculate land area percentages and compare the two. This study opens the avenue to consideration of water quality, population changes, land use, habitat, topography, soil evaluation and town planning and zoning. Developed by Edward Duncanson, the activity includes materials for 10 setups and instructions.

Students really enjoyed. - Our students really enjoyed this activity & thought it was pretty poignant showing the loss of land & how suburban sprawl moves quickly. It sparked discussion in how the local environment has changed and where to go to get local maps to compare.

Coloring in squared seem daunting at first but in pairs with one reading maps & other marking squares it went quickly.
