1. HOW MAPS MAKE DATA VISIBLE Using Maps in Science

2. Maps There are many different maps that can be used in both science and social science. In the study of Urban Ecology, all types are very useful  Census Maps  Topography Maps  Road Maps  City Maps  Distributions Maps

3. Terms you should know Latitude - A measurement of distance north or south of the equator  Context: Latitude is measured in degrees using imaginary grid lines called parallels. Longitude - A measurement of an object’s east/west position  Context: Longitude is measured in degrees from the prime meridian in Greenwich, England GPS (Global Positioning System) - A system of satellites and receivers that pinpoint location by measuring time differences for receivers’ signals to reach the satellites  Context: Developed by the military, GPS has become indispensable to many

4. Terms you should know! GIS (Global Information System) – A computerized mapping system that allows us to visualize, question, analyze, and interpret data to understand relationships, patterns, and trends  Google Earth  ArcGIS (ESRI)  GRASS GIS

6. Urban Sprawl Urban Sprawl - a situation in which large stores, groups of houses, etc., are built in an area around a city that formerly had few people living in it The map you saw was a satellite image of changes that have happened from 1984 – 2012.  In the past 30 years what can you say about the size of the Urban environment in Chicago?  Why would an Urban Ecologist be interested in this information?  What impacts may this expansion have on non-Urban environments?

7. Maps and Data observation #2 https://www.youtube.com/watch?v=UlQAxxyXhJI Again watch this video from start to finish. We will go through it twice.  Identify at least 2 things that you found interesting in the video.  Be Prepared to share!!!

8. Maps and Urban Health Take out your map of the Soho District that you picked up when you walked in today. John Snow was a physician who used maps to help identify the origin of this disease and how it was spreading.

9. Maps and Urban Health Pumps – in 1854 homes did not have running water. The pumps were where households needed to go to collect their water for the day. What questions would you need to ask about Cholera to help you figure out how to prevent it?

10. Maps and Urban Health First we need to identify what is on the map.  The black bars on the map indicate individuals who were infected with Cholera. Take 2 minutes with your partner to go through the map and identify any other information that you think might be useful that you could use.

11. Exit Ticket - On Index Card 1. Give your own definition of Urban Sprawl 2. Identify 1 abiotic component, 1 biotic component and 1 man-made component. 3. Explain how a community is different from a population.
