The two best activities that can most readily be used in classrooms are the density of the crust activity and the drilling rate activity. Both activities use real data from expedition 309. The density activity allow students to determine the relationship between density and depth in the ocean crust, while the drilling rate activity allows students to calculate the drilling rate of Expedition 309 over the course of three days.
The other activities allow students to identify and describe distinguishable characteristics in one or more core sections, use guides to catalogue and label one or more core samples, examine and match whole thin section photos taken under the microscope to the cores from which they were sampled.
