Sažetak
Even today dominant teaching methods in science classroom are traditional ones, though their final result is simple accumulation of information and facts, without in-depth comprehension. Traditional method of teaching pH value and indicators only occasionally involves experiments, using synthetic indicators, which can be expensive and unavailable to schools. However, plant pigments are pH indicators as well, hence a series of experiments using plant materials, which pupils use in everyday life, was created. Studied plant material included various types of berries (strawberries, raspberries, blackberries, mulberries, etc.), not only in the form of fresh fruit but also as various fruit products (dried fruit, tea, juice, jams, preservatives, vine). Our aim was to obtain simplicity of indicator preparation, low cost, easy availability whole year, easy maintenance and higher indicator durability. To this purpose we studied indicator preparation in several concentrations (to find the optimal one considering simplicity of preparation, cost, duration) and used fruit products with maximal fruit concentration and without artificial components. Our results indicate a great potential of application of fruit and fruit products as acid-base indicators in the modern classroom in order to broaden pupils interest in this subject, and to enable successful relating of science information with everyday life.
