Day 1

GIS Storm Sewers Unit

 

Introduction to unit. Pretest.

1. Introduce the “driving scenario problem”:
South Bethlehem has horrible flooding problems when it rains. The rain water flows like crazy down the North/South roads and water becomes many inches deep on the East/West street. This is a serious problem. On rainy days, kids are walking into the 48 Hour Video store with wet socks and shoes to get their video games. The water also piles up in front of “The Cup” and nobody wants to walk through big puddles to get ice cream. Business is bad on the South Side on rainy days. The city of Bethlehem has commissioned us to investigate this problem. We will learn special surveying skills with handheld Global Positioning devices – GPS, and GIS – Geographic Information Systems to investigate this issue and come up with a solution to help out this water problem on the South Side.”

2. Instruct students to complete the pretest.

3. Instruct students to complete the “Draw a map task”:
