In this introductory activity, students learn about perspective, range and resolution and explain how the optimal viewing zone varies with what it is they want to know. Students view a large object such as a poster, store front, or even a brick wall from various distances and observe the difference in the information they can get from each perspective. Supplies required include a large sign or poster, metric ruler or measuring tape, chalk, and a magnifying glass. This activity is part of the Ground Truth Studies Teacher Handbook, which provides more than 20 activities to build student understanding of global change and remote sensing, and includes background chapters for teachers, glossary, and appendices.
