NATURAL SCIENCE AND MATHEMATICS INTEGRATION POSSIBILITIES RESEARCHING WATER SALINITY

Interdisciplinary natural science education relations are developed mostly between biology, chemistry, physics, mathematics and information technologies. The teachers have to convey education content, consisting of separate concepts, laws, theories as a harmonious whole, revealing interrelation between the analysed phenomena. Organising natural science teaching in this way, the teaching material is reorganised, systemised. Solving interdisciplinary integration problems, active communication and cooperation is going on between individual natural science teachers. Seeking to generally and newly look at the natural science teaching and learning process, grounded on interdisciplinary relations, interdisciplinary experiments are carried out. Water salinity research has been chosen, because in this topic analysis, rather wide integration possibilities are discerned. Physics teacher together with the pupils would deepen the knowledge of conductivity, electrolytes, electric current in the electrolytes, chemistry teachers – of electrolytic dissociation, solution concentration, mathematics teachers - would remember percent calculation, linear equation analysis, biology teachers – about water salinity effect on the man and on the environment surrounding him. In the article, lesson organisation and research performance methodics is discussed, the essence of practical work is explained, tasks and examples are presented. Several different subject (physics, chemistry, biology, mathematics) teachers could participate in the lesson, which could form the conditions not in disintegrated way, but systematically convey the pupils the essence of the analysed phenomenon.
