Pollution is not a problem we just read about anymore. It affects the air we breathe, the land we live on, and the water we consume. After noticing a lack of awareness in students, a lesson was developed that used Google Earth to pinpoint sources of pollution in the local area and in others across the country, and their effects on the surrounding watershed. The technology used in this lesson helps students overcome misconceptions and better understand the science content. This article describes the activity in detail. This activity can be easily adapted for diverse learners, ability levels, available technology, and time constraints. The activity fosters data interpretation, analysis, inference, communication, and writing skills. The technology used enhances instruction, increases students' understanding of science content, and helps them develop important 21st-century skills.
