A Comprehensive Classroom Survey Set of Minerals and Rocks
- Descriptions of each specimen

An exceptional value for a quality collection. Originally developed by Ward's®, over the years the Washington School Collection has become one of the most widely accepted secondary-school earth science teaching aids. Carefully selected, high-quality rock and mineral samples provide students with an excellent introduction to earth materials and their characteristics. A matching set of testing chips, ideal for quizzing students on specimen identification, is also included. The set is housed in a compartmented collection box, and descriptions of each specimen are printed on a label in the lid of the box.
40 numbered samples, 1" x 2"40 matching testing chips, 1/2"
