Purpose

The purpose of this activity is to engage students in evaluating a claim made on the basis of supporting statistics.

Achievement Objectives
GM4-5: Identify classes of two- and three-dimensional shapes by their geometric properties.
GM4-6: Relate three-dimensional models to two-dimensional representations, and vice versa.

Activity

Pyroxenes are minerals found in cooled volcanic lava. They have an interesting geometric structure.

 

Identify and list the irregular polygons that make up the pyroxene crystal shown in the diagram.

 

Use this list to construct a net for a pyroxene crystal.
