Mapping the Unknown Sea Floor Lab Activity
|
By inserting “sounding rods” through a box containing one of four unknown sea floors, students measure depth and chart it on grid paper, then cut and paste the paper to form a scale model of the floor. Students can plot a guyot, rift valley, seamount, or volcano. Each kit includes a box, sea floor form, three rods, pad of plotting grids, instructions, and teacher’s guide.
