Chemistry class

from Wikipedia, the free encyclopedia
In chemistry lessons, students should be instructed to discover and examine substances , substance properties and substance conversions and to apply their research results to new problems

Chemistry class is the information in the scientific school subject chemistry in schools and educational institutions . Here, the content of chemistry for the classroom is prepared, taught and learned according to the rules of didactics and subject didactics of the school subject chemistry for school, training and further education (see under chemistry didactics ).
The chemistry classes in the professional school differs from general chemistry lesson in particular in that occupation-specific techniques and skills taught and practiced.

Motivation for chemistry class at school

Our everyday life can only be partially understood without knowledge of elementary scientific contexts. The development and research of industrial production processes that use mathematical and scientific knowledge have led to far-reaching changes in history and today (for example industrial revolution, modern communication technology).

It is the task of chemistry classes to provide insight into the composition of materials and processes in nature. Conversions of matter in animate and inanimate nature are also based on chemical reactions and should be recognized as such. Likewise, the imparting of scientific knowledge should be used to build an understanding of modern technology and a positive attitude towards it, since chemistry in particular has made a significant contribution to improving human living conditions through the introduction of new products. Chemistry can also facilitate access to philosophical questions, such as the origin of humans or the creation of the universe (see for example the Vis vitalis hypothesis).

However, the problems associated with the application are also discussed and, if necessary, criticized with the help of the acquired basic knowledge. It is important that chemistry not only causes environmental problems, but can also help to solve them. In addition to scientific methods, models of the structure of matter should also be developed.

School material ( curriculum , course content and topics)

Chemistry Lesson in a Vocational School (December 22, 1983)

The distribution of the material over the school years is regulated differently in the various states and federal states. This is why this overview ( secondary level I ) is kept very general.

  • During the introduction to chemistry , the students should not only acquire basic experimental knowledge, such as handling Bunsen burners and hazardous substances, but also understand what chemistry is all about .
  • Substances and their properties should lay a foundation: Substances that are used in everyday life should be familiarized with and investigated in experiments , their basic properties should be known ( e.g. salts , acids , metals and non-metals ...) and their classification into groups of substances .
  • Mixtures of substances and pure substances : The pupils learn that mixtures of substances can be separated by physical methods ( separation methods , separation processes, separation techniques ) based on their substance properties (distillation, decanting, filtering, sieving, sublimating, ...).
The formation of rust ( corrosion ) as a slow chemical reaction that can be experienced in everyday school life:
oxygen and water (moisture) oxidize iron

In the upper secondary level , the following topics are usually also dealt with:

In order for chemistry lessons to function properly, state schools must have modern chemistry rooms and a chemistry collection, for the material and financial arrangements of which there are written recommendations from the responsible school authority . To ensure safe and orderly operation, the school management must commission a competent teacher who is able to apply and implement the provisions of the RiSU . The DGUV u. a. through the "Safe School" website and the DeGINTU safety tool , which can be used to create interactive risk assessments and a chemical register. For further education and training is involved within the German Chemical Society , the Department of Chemistry lessons that the magazine Chemkon out there. Other magazines for chemistry classes include: B. Science in the classroom - chemistry and chemistry in our time .
