Stillwater, MN 9th Grade AP Geology students use new technology to map data

James Warden:

Brady Tynen needed to find out which states have the largest concentrations of people with mixed American Indian-African American ancestry. The Stillwater Junior High ninth-grader could have pored through the U.S. Census database, noted the appropriate percentage, ranked the states in a list and tried to divine some trend.
Then again, his geography class is just 50 minutes long, and Tynen needed to repeat Wednesday’s exercise two more times for different groups.
Thankfully, the Census website can show the information on a map with the press of a few buttons. In mere minutes, Tynen could tell that the group he was looking at is concentrated in the eastern U.S., particularly southern states like Louisiana, Mississippi and Georgia.
“Maps are a good way to find out all sorts of things,” he said. “It’d be kind of hard if you didn’t have a map because maps organize your data.”
The exercise gave students in Sara Damon’s ninth-grade Advanced Placement geography class a taste of a technology called geographic information systems (GIS). GIS is simply technology that merges data with maps. Something as basic as Google Maps can be considered GIS because it links a map to data, in that case street addresses.

Stillwater high school offers 17 Advanced Placement classes, according to the AP Course Audit Website.
