AB  - This cross-age study aimed to provide an insight into the development of stu- dents’ understanding of the concept of matter, at the macroscopic and sub-microscopic level of chemistry knowledge. The research sample encompassed 121 students aged 14 years, 108 stu- dents aged 16 years and 112 students aged 19 years. All students completed the test comprised of five pictures and five schemata which depicted a monatomic/diatomic element, a compound and a homogeneous/heterogeneous mixture, at both of the levels. In this way, it was examined whether the selected age groups exhibit significant differences in understanding of elements, compounds and mixtures at the above-mentioned levels and whether the depth of understanding of these concepts at the macroscopic and sub-microscopic level significantly changes with the age of students. Research results indicate that all three age groups have a significantly better understanding of diatomic elements, compounds and heterogeneous mixtures at the macro- scopic, in comparison to the sub-microscopic level and a significantly better understanding of monatomic elements and homogeneous mixtures at the sub-microscopic, in comparison to the macroscopic level. Overall, a significant improvement of understanding of the concept of matter, at each of the levels, was only observed between the ages of 14 and 16.

AB  - Industry field trips provide the contexts that enable students to improve their understanding of chemical concepts and processes. The aim of this research study was to explore to what extent
students improve their understanding of water, solutions, mixtures, and the methods used for separating mixture components in the context of the waterworks, and what their views towards such an approach are. The sample consisted of 36 students aged 13 to 14 years, equally divided into the experimental and control group. The teaching unit Water and its significance for the living world was realised within the context of the waterworks in the experimental group, while in the  control group it was realised using a conventional approach at school. Prior to the elaboration of the teaching unit the students from both groups had been tested using a pre-test, and upon the completion they were tested using a post-test. The views of the experimental group were examined using a questionnaire. The obtained results showed that the activities in the context of
waterworks improved the understanding of the studied concepts, that students recognised the relevance of the applied context for their personal and societal life, as well as for their own future professional activities.
