Each participant discovers the length of her or his own individual pace (while one pace equals two steps) by taking ten paces three times and finding the average of those three trials. Then participants count paces to experience the distance of 50 meters.
This activity allows you to make more detailed and quantitative measurements along four transects of a 50m by 50m square observation area (pixel) that can be compared with the percentages estimated using the GLOBE Observer: Land Cover tool and satellite-based maps.
