Correlating Sedimentary Strata
Students examine four drill cores representing a fictional series of rock layers. They then use the evidence from each drill core to create a stratigraphic column for each location and use evidence from the cores to correlate to the layers from the different locations. They are then challenged to use this fossil evidence to construct a timeline showing the relative time spans of each species represented by the fossils. Students construct a scientific explanation based on evidence from rock strata for how the geologic time scale is used to organize Earth’s 4.6-billion-year history. The crosscutting concepts of pattern, scale, and stability and change are reinforced.
