This is a multiday lab module. The first few pages involves project directiosn for students to make a model of the geologic time scale. Hopefully, this will expand their perception of time. The second half of the module involves: media to explain sampling of the ocean crust and core sampling, labs on the density of ocean crust and continental crust (using rock samples), students will calculate the density vs. depth on a sample core. The third section involves students using density cubes (purchased thru flinn and cut lumber to show the principle of isostasy and how/why the plates float on the mantle.
