“…After a certain period of time has passed, the most critical points can be checked more often, and even continuous monitoring of the situation and the disposal of non-degradable waste can be carried out. In this way, in the club, realizing extracurricular employment of students, we stimulate the development of their habits and skills [4], [13].…”

In recent decades, there has been a sharp increase in waste that pollutes the environment. It can be categorically stated that non-degradable waste has the largest share in them. They are most easily discharged and condensed in water bodies on land, and subsequently in the world's oceans. Still, measures are usually taken after floods or other emergencies occur. Not enough preventive measures are being taken. The report proposes a model for monitoring and recording unregulated dumping in and around mainland water bodies. The aim of the research is to develop a system for monitoring pollution in and around water bodies, transmitting this information, analyzing it and making decisions about the removal of pollutants. As a secondary goal, a preventive measure to limit pollution can also be indicated, because when there is control and subsequent punishments, the violations also decrease to a significant extent. A review was also made of good practices in the collection of waste in water bodies. A system for collecting information and removing the accumulated waste is proposed. It is also proposed to implement a method put in place last year in Australia to collect waste in running water. A mobile version will also be developed to signal the presence of waste, when every citizen will be able to signal the presence of such unregulated pollution. You will also use your knowledge after equipping the astronomy club to observe space debris and to create floating island fruits from the plastic waste in the world's oceans. In addition, technologies are used that are innovative and have the potential to solve these global problems. In carrying out the research, various methods were used - analysis, data synthesis, data processing and others.

In the last decade, the need for specialists in the field of engineering and exact sciences emerged in Bulgaria and around the world. This led to the launch of a National Program for the construction of stem centers in schools. From the Veliko Tarnovo region, 16 schools joined the program at different stages, where STEM centers are being built or are already functioning in various subjects, which significantly support the preparation of quality personnel for the Bulgarian economy. A review and analysis of the expectations of teachers and students from work in centers with an engineering focus and training in natural sciences was made. At the next stage, an analysis and evaluation of the effect of the implementation of these innovative centers will be done.

“…Air density, aerosol concentration, atmospheric pressure, air and soil temperature also affect the rate of change of the natural radiation background after a nuclear accident or other action that is accompanied by radioactive radiation, but their influence is very small and therefore when determining the radiation situation, they are not taken into account. Bulgaria is located in South-Eastern Europe, it is characterized by a moderate climate and there are no anomalies in the presence of abnormal amounts of the components of the atmospheric air at different heights above the earth's surface [2], [8], [9].…”

In the analysis of the meteorological elements that influence the spread of radioactive particles, radioactive isotopes and dangerous chemical substances on the territory of Bulgaria, the winds and air currents that form in the airspace over Bulgaria are considered. These are the main meteorological elements that most strongly influence the change in the radioactive background. Another element that has an impact is precipitation in its various manifestations - horizontal and vertical in appearance and depending on the aggregate state of the water. Due to their negligible influence on the radiation environment, we will exclude the remaining meteorological elements from the factors forming the natural indicators of the state of the atmosphere, water and soil. Their influence in areas where there are located large enterprises working with such substances is presented.The report examines the influence of the main factor - the movement of air masses at different altitudes in the atmosphere in the Ludogorie region and the Danube River as an area where NPPs are located in Bulgaria and Romania and which, in the event of an accident, would cause the greatest consequences. The winds in 3 cities from this region, which are located near these enterprises, are described and the corresponding analysis is made.
