Journey to Earth’s Center

Explore inside Earth the way seismologists do. Open a cut-open Earth in three views (its layers, earthquake waves, and true proportions), then work through four investigations: why S waves stop at the outer core, why there is a P-wave shadow zone, how Inge Lehmann found the inner core, and how thin the crust really is. Each one asks for a prediction first, then runs the experiment. A journey of eight stops shows the depth, pressure, temperature, and wave speeds from the surface to the center. With a student worksheet and a teacher answer key. Personal, creator, and public display licenses. From $19.
