A GREAT teach)ing tool. Allows students to
construct a logical sequence of sedimentary layers in a squeeze box,
then apply a convergent force with the plunger in the box causing
the layers to fold, and then fault. Shows dramatic visualization of
the principle of superposition; concepts of transgression, regression
and compression; patterns of change, faults and plate tectonics and
There are (5) pegs, spaced at 30mm, or 3cm, on the plunger shaft
to control the distance the plunger is
moved forward. On top of the plunger are
(5) holes for peg storage.
The five pegs enables students to make "measured" changes in the
amount of compression and allows students
to observe changes at each compression.
Includes a complete lesson guide with student activities with tranparent 30mm graft insert and student worksheets..
Made from light weight MDF, wooden dowel, clear high impact plastic
