The major objective of this thesis are carnivorous plants of the genus Nepenthes and their pedagogical and educational usage addressing students of elementary and grammar schools. The first part provides a general description of the Nepenthes plants, often called tropical pitcher plants due to their pitcher-shaped leaves that function as a passive pitfall trap. Moreover, the field research on the Nepenthes digestive fluid acidity was undertaken at Borneo. Plant's acidity was measured by the pH meter with glass electrode. The results obtained prove pH level differences for various Nepenthes species. In addition, pH level differences in between the fluid from freshly opened pitcher and an older fluid were observed. All results are cross-validated with the values reported in literature. On the basis of the results of the field research, didactic part is assembled. The didactic part consists of the Nepenthes general description and proposal of educational activities aiming at the botany popularization in elementary and grammar schools. Subsequently, the method proposed is tested in biology classes of the second grade of elementary school. The results reveal a positive influence of the method on student's interest in botany.
