This activity sets the stage for a series of learning activities that use authentic scientific ocean drilling data. Scientific ocean drilling is used to obtain cores of and geophysical wireline logs from holes drilled into the sediments and rock the seafloor. Scientists study the cores and logs that they collect and extract geological, geophysical, geochemical, and environmental information that provides insight into the Earth system. This knowledge enhances our ability to forecast possible future events or conditions, including global climate change.
Most scientific ocean drilling is carried out by the Integrated Ocean Drilling Program (IODP), an international partnership of scientists and research institutions organized to explore the evolution and the structure of Earth.
The learning activity introduces students to the purpose, history and technology of ocean drilling. Students practice describing model cores designed to simulate real cores retrieved by scientific ocean drilling. They work in teams to interpret their observations, carry out hole-to-hole correlation, develop conclusions, and present results to fellow students. The activity was created for 8th Grade students, but is suitable for high school level students who have little or no knowledge of scientific ocean drilling. We show the correlation to both the middle school and Earth and Space Science TEKS.

Interesting - 4.73; applicable to the implemntation of guided inquiry in the classroom - 4.68; applicable to my use of in-class technology - 4.03
Loved this! I would use this in ESS as a way of tying together stratigraphy, index fossils, environments of deposition, and rock types. A great culminating activity that can also be used to discuss how we get cross-sectional diagrams.
I like this activity very much and will try to build the core samples over the summer for next year. I would also like to develop a cross section to show where each of these core samples fit in and have the students develop a geological history to go along with the samples and cross section.
We would like to thank Sean Gulick, John Goff, and Lisa Gahagan for assistance with this learning activity.
