The minerals are classified into groups based on these structures. In each of the 7 thermodynamically stable crystalline forms or polymorphs of crystalline quartz, only 2 out of 4 of each the edges of the {SiO 4 } tetrahedra are shared with others, yielding the net chemical formula for silica: SiO 2 .
Science Research Associates Inc. was founded in 1938 [1] with a trade and occupational focus. In 1957, it moved into individualized classroom instruction with the iconic SRA Reading Laboratory Kit, a format that they translated to mathematics, science, and social studies [1] commonly called SRA cards.

Because this style of test does not require a teacher to interpret answers, test-takers are graded purely on their selections, creating a lower likelihood of teacher bias in the results. [8]
Within the field of geology, Bowen's reaction series is the work of the Canadian petrologist Norman L. Bowen, [1] who summarized, based on experiments and observations of natural rocks, the sequence of crystallization of common silicate minerals from typical basaltic magma undergoing fractional crystallization (i.e. crystallization wherein early-formed crystals are removed from the magma by ...
