Role of micro experiment in chemistry teaching

In the theoretical part of the thesis the literature on the importance of integration of experimental work in teaching chemistry was examined. There were presented the conditions for carrying out the experimental work, safe handling with chemicals and the concern for proper waste disposal. The main focus is put on execution of micro experimental work in teaching chemistry, and it was examined, the development of ideas and a variety of possibilities for micro experiments, evaluation of advantages and disadvantages which have been brought into teaching chemistry with performing experiments. In the experimental part of the thesis three types of experiments were chosen, which are suitable for independant experimental work of pupils. The chosen experiments were tested and upgraded in two versions: the ordinary (macro) experimental execution and execution of micro. The focus was on the comparison between the two types of experimental work; the monitoring of the amount of used chemicals, costs of implementation, the time needed for the completition and availability of laboratory inventory (sufficient number of pupils for pair work). In accordance with the objectives of the curriculum for chemistry in primary school lesson plans for teachers and worksheets for pupils to carry out selected experiments in both versions were made
