In this fieldwork activity, students learn that when setting up a research design a system's boundaries are based on the question(s) a scientist wants to answer. Students ground truth, or validate, a pixel within a homogeneous area of a satellite image and ask and answer questions related to their observations. Equipment needed to do this activity include a compass and camera. This is a learning activity associated with the GLOBE Land Cover/Biology investigations and is supported by the GLOBE Teacher's Guide, Land Cover/Biology. GLOBE (Global Learning and Observation to Benefit the Environment) is a worldwide, hands-on, K-12 school-based science education program.
