SummaryGeographic information systems (GIS), once used predominantly by experts in cartography and computer programming, have become pervasive in everyday business and consumer use. This unit explores GIS in general as a technology about which much more can be learned, and it also explores applications of that technology. Students experience GIS technology through the use of Google Earth on the environmental topic of plastics in the ocean in an area known as the Great Pacific Garbage Patch. The use of this topic in GIS makes the unit multidisciplinary, incorporating the physics of ocean currents, the chemistry associated with pollutant degradation and chemical sorption to organic-rich plastics, and ecological impact to aquatic biota.
GIS is a tool used in many different engineering disciplines, including environmental, petroleum, ocean and civil. GIS often involves looking at large datasets to draw conclusions from spatial patterns. And GIS is essential in planning of engineering projects. Nearly any engineering that is in some way connected with field-based projects used GIS in some way.
This unit is divided into two main thrusts. Part 1 addresses GIS in general. This topic is covered most heavily in Lesson 1, "What is GIS?" and Lesson 2, "Projections and Coordinates: Turning a 3D Earth into Flatlands." Additionally, Activity 1, "Who Can Make the Best Coordinate System?," Activity 2, "What's Wrong with the Coordinates at the North Pole?," and Activity 4, "Searching for Bigfoot and Others Lke Him" help supplement this first part of the unit.
Part 2 of the unit includes Lesson 3, "The Great Pacific Garbage Patch," and Activity 3, "Plastic in the Ocean: Get the Word Out at McDonalds!," Activity 5, "Where Are the Plastics Near Me? (Field Trip)" and Activity 6, "Where Are the Plastics Near Me? (Mapping the Data)." These focus more on using GIS for a particular application: the study and representation of data related to the Great Pacific Garbage Patch.
If the teacher wishes to simply give students exposure to GIS and digital mapping concepts, then use all or some of Lessons 1-2 and Activities 1-2, 4 without reference to any of the environmental concerns of the other half of the unit.
If, however, the teacher is more interested in the environmental side of the unit and less in the GIS aspects, then all or parts of Lesson 3 and Activities 3 and 5 go far in exposing students to an environmental issue that relates to their own community. Following this more environmental approach, students are asked to understand scientific information that they find on their own, evaluate its usefulness, and give credit to its source.
Activity 6 is the exercise that puts together both what students are expected to learn from the GIS side of the unit and the solid waste environmental side.
Each TeachEngineering lesson or activity is correlated to one or more K-12 science,
technology, engineering or math (STEM) educational standards.
All 100,000+ K-12 STEM standards covered in TeachEngineering are collected, maintained and packaged by the Achievement Standards Network (ASN),
a project of D2L (www.achievementstandards.org).
In the ASN, standards are hierarchically structured: first by source; e.g., by state; within source by type; e.g., science or mathematics;
within type by subtype, then by grade, etc.

The Great Pacific Garbage Patch (GPGP) is an intriguing and publicized environmental problem. Through exploring this complex issue, students gain insight into aspects of chemistry, oceanography, fluids, environmental science, life science and even international policy.
Through an adult-led field trip, students organized into investigation teams catalogue the incidence of plastic debris in different environments. They investigate these plastics according to their type, age, location and other characteristics that might indicate what potential they have for becoming...
Activity 6 is the culmination of all of the information in the entire unit and could be used as a summary assessment. If desired, you could give an exam that covers all of the unit concepts (not included). But, since GIS is so application focused, it is recommended that students are assessed more on their correct use of it and understanding of their results rather than being specifically tested on GIS concepts in a more formal way.
