READING RIVER SEDIMENTS:
SIMULATED MINERAL EXPLORATION
Kit #435

Students conduct a mineral exploration which simulates real-life economic, societal and issue-
oriented problems . The activities are designed to introduce and use topographic maps and learn
about rock types, erosion and river dynamics . The kit is based on the understanding that as water
works along the Earth’s surface and through the ground, it picks up small amounts of the minerals
found in the rocks and sediments. Certain minerals ionize, then travel along in the moving water
and later react chemically with the surface of river sediments . The closer the section of river is to a
mineral deposit, the greater the detectable amount will be of the river sediments .
Accommodates three classes, each with 15 groups of two students.

GEOMETRY OF CRYSTAL STRUCTURE

Kit #401
Using a unique approach to explore crystal structure, students
use transparent pre-cut shapes to construct models of the six
basic crystal shapes . They insert axes at established center
points on each crystal face . Using the provided goniometers,
students measure the length of the axes and the angles
formed . They observe the geometric shape of all facets
(squares, rectangles, and triangles) and record the data about
each crystal form . By rotating the model on a central axis,
students study the symmetry and repetition of forms .
Accommodates unlimited classes, each with 15 groups of two
students.
