Ways to Conserve Water Take shorter showers Turn off the water while brushing your teeth Water your yard before 10 AM and after 6 PM Water twice a week according to your address Do not water during any form of precipitation Maintain sprinkler systems Glossary DISD - Dallas Independent School District EEI (Environmental Education Initiative) - a K-12th grade school and community outreach program funded by the City of Dallas and administered by the Science Education Research Laboratory (SERL) at the University of North Texas. G.I.S. (Geographic Information Systems) a tool used to visualize, question, analyze, interpret, and understand data to reveal relationships, patterns, and trends. ZCTA (Zip Code Tabulation Area) an area established by the Census in order to collect and report data. ZCTAs are similar to Zip Codes. Research Boundaries Zip Code Map ZCTA Map Established by the post office in 1970s to make addressing easier. Established by the census to help collect data. City of Dallas Outline: ZCTA Overview Summary of previous year 2012 Research plan Results Next steps In the Field Training G.I.S. Learning Experiences Wastewater/water treatment plants Summary of Previous Year (2011) Reevaluated research areas based on three years of water usage data Built maps using G.I.S. software representing the research areas Presented results of water data comparisons Research Purpose Overall Goal: Through this study, we aim to measure the effects of education on public behavior in relation to water consumption. Steps to Reach Our Goal: Attempt to define a research area. Which areas to conduct the intervention and why? Through our analyses this summer, we attempt to define two research areas establishing a control and an area to permeate with education.
