Book title by Cuny - Chemie

Karl Heinz Cuny (born September 29, 1910 ; † October 17, 1994 ,) was a German senior teacher in the Hessian school service. The textbook "Cuny - Chemistry", published by him from 1963 and published in ten editions by Hermann Schroedel Verlag , was a standard work for chemistry lessons at grammar schools in the Federal Republic of Germany.

The didactic characteristic of the book was its structure with textually integrated teacher experiments and student exercises. The orbitals of the hydrogen atom shown on the cover of the book underscored the fact that the latest knowledge of the time was included in the textbook.

Also published by Hermann Schroedel Verlag under Cuny's editorship in several editions from 1966 "Cuny - Basics of Chemistry" and from 1968 "Cuny - Chemistry Upper Level" and 1971 "Cuny - Basics of Physical Chemistry".

From 1975 onwards, the successor to chemistry lessons at grammar schools, "Cuny-Weber - Chemistry - World of Materials", was published by Hermann Schroedel Verlag , jointly edited by Karl Heinz Cuny and Walter Weber. A special feature of the textbook was the continuous two-column structure with a column in which the technical knowledge is presented and a column in which instructions for experiments, descriptions of experimental set-ups and explanations can be found.

As a didactic engineer for chemistry lessons in schools, Karl Heinz Cuny was a clear advocate of the inductive method , which leads the students from experiment to understanding the general laws of chemistry, instead of teaching the theory first and then - if at all - the practical one Try to show.

Other works published by Karl Heinz Cuny were: "Introduction to chemistry - we experiment with structural parts" (1967 published by Julius Beltz ) and the "worksheets for chemical student exercises" (1969 also published by Julius Beltz ).

Karl Heinz Cuny was also the inventor of the first tube eudiometer , in which the use of a transparent, soft plastic tube avoids the disadvantages of the glass eudiometers that were previously used to determine the volume ratios of explosively reacting gas mixtures - especially the danger of flying glass fragments. The device can be used in school lessons, for. For example, it can be demonstrated that hydrogen and oxygen only combine to form water in a volume ratio of 2: 1.
