When the groups have finished contouring their data, ask them to examine what they see. Have each group present their findings to the class. The students may name coring through ice sheets, finding depth in the ocean, and other exploration. Coring, or probing, can be expensive and the results are only for a single point. These results are extrapolated to other areas.
Explorers can miss information.
In the next activity, students will explore other methods used by scientists to explore places they cannot visit in person. Please review this activity.
