Ignored Role of Vegetation in Solar Energy Distribution and Formation of Climate – Survey of the Knowledge of Novice Pre-service Science Teachers
Main Article Content
Abstract
In human environment, vegetation plays a key role for the local climate formation and water supply of the landscape. Due to evaporation of water (evapotranspiration) the vegetation convert the solar energy into the latent heat and cools the environment with a power of several hundred W.m-2. By this way the vegetation cover helps to mitigate the impact of global climate change and plays significant role for the maintenance of sufficient water supply for the next generations. Despite of this crucial importance the general knowledge of the role of vegetation in solar energy distribution and local climate formation seems to be poor. Insufficient attention is paid to this topic already at the schools. This contribution brings the results of the survey focused on the knowledge of novice pre – service science teachers of Faculty of Education, University of South Bohemia. According to the results of this survey, the novice pre-service science teachers understanding of the role of vegetation in solar energy distribution and water cycle in the landscape is low. Critical points are insufficient knowledge of plant transpiration and proper understanding of the casual links between physical and physiological processes and the role of vegetation in a short water cycle. The contribution brings also brief didactic overview of the role of vegetation in water cycle and solar energy distribution in the landscape.
