    Abstract

    The intention of this thesis was to research and find ways on how to present the properties of water to the general public and/or pupils in primary schools. I have formed a sequence of experiments (called a »science adventure«), which explain various properties of water, such as its structure, the phases of water (gas, liquid, solid) and circulation of water in nature. They also show effects of environment variables such as temperature and pressure on the phase equilibriums and how an added solvent affects certain physical and chemical properties of water. In the first part of the thesis, water is presented from a theoretical standpoint (structure, phase diagram, effects on phase equilibrium and cryoscopic properties). Part two contains an in-depth description of the experiments, which can help a teacher with lectures on water. These experiments also form the main part of the »science adventure«. The third part is the so-called »science adventure« (a title given to an interactive demonstration in Hiša eksperimentov) itself which connects all of the experiments in a story. The goal of the science adventure is to present water and it's properties. The last, fourth, part of the thesis contains a worksheet, which pupils can solve after seeing the »science adventure« or after the lectures on water, and is intended to solidify their knowledge of water.
