	abstract = {The aim of this research was to examine the effects of a new platform for raising the pre-service chemistry and geography teachers{\textquoteright} awareness of cooperation possibilities associated with the planning relevant interdisciplinary lesson. The research featured the participation of 16 students of the Faculty of Chemistry and 28 students of the Faculty of Geography of Belgrade University. Two workshops were conducted within the research. During the first workshop the participants worked in small groups on the tasks which served to strengthen their awareness on the relevant science education. The second workshop comprised the jointly planning the interdisciplinary lessons in groups with members of the pre-service teachers of both subjects. The participants{\textquoteright} lesson plans contain goals that can be classified as those relevant for the individual and those relevant for society. Half of the lesson plans contained formulations of goals that can be assessed as relevant for certain professions. The activities planned for the attainment of the stated goals support an interdisciplinary approach, encompass the concepts envisaged by the chemistry and geography curricula, and the activities specific to these two subjects.},

	abstract = {The aim of this research was to explore students{\textquoteright} ideas about chemical reactions and difficulties in understanding the law of conservation of mass in such reactions by using an approach that started from presentations of scientists{\textquoteright} work associated with the law. The developed test items relied on: 1) the historical contents that illustrate the experimental work of three scientists (Lavoisier, Landolt and Lomonosov); 2) the description of school experiments and 3) real life situation. In this way, students would have an opportunity to show understanding of the law of conservation of mass in two contexts, one based on the stories from the history of chemistry and the other contemporary, based on school laboratory experiments and real life situation. Students of different ages were selected for the research: the seventh and the eighth grade of primary school (age 13{\textendash}14), and the second year of grammar school (age 16). The research involved a total of 301 students. The results indicated that students{\textquoteright} difficulties were mostly associated with the predictions and explanations of mass changes in open reaction systems in which a gas was a reactant than with the reactions in which a gas was a product. },
