Abstract

Experiments have a dominant role in the education of natural science subjects. It has been our experience that students have been very satisfied, if the materials used in the experiments were well known substances to them, in this case foodstuffs. Again, 10 simple experiments of physical, chemical and biological type are described, concerning the following topics: measurement of the temperature of black coffee and milk exposed to natural light, study of capillarity in a sugar cube dipped into coffee or red wine, measuring honey viscosity, determination of the acid content of vinegar, the change of cooking oil viscosity as a function of temperature, measurement of concentration on the basis of the law of Archimedes, acidity measurement of fruits, measurement of the alcohol content of alcoholic beverages, microscopic examination of yeast, study alcoholic fermentation produced by yeast. Foodstuffs used during the investigations and measurements: apples, black coffee, brandy, fruit juice, honey, milk, oranges, red wine, rum, sucrose, sunflower oil, vinegar, wine, yeast.
