The Teacher Set contains 20 rocks and 20 minerals, numbered and keyed to an informative identification list.
Rock-forming minerals, metallic ores and other useful minerals are all represented, as are igneous, sedimentary and metamorphic rocks. The teacher's specimens are supplied in a multicompartment box.
The Student Set contains the same 40 specimens as the Teacher Set. These samples, however, are smaller and unlabeled, making them ideal for quiz or testing purposes.
Note: collections are subject to change depending upon availability of individual items.
