Abstract :

Natural science education at a secondary school aims at developing the competence in natural sciences in greater depth. In addition to expanding the contents of natural science as a discipline, it also develops students‘ research skills. They learn to consider and apply ideas, laws, and methods of natural sciences in creative and critical ways. I am presenting my students‘ creative project called “The Measurement of Vitamin C“. The goal of our work was to trace the amounts of vitamin C in various fruits and vegetables. We were tracing vitamin C using titration method. The results of our research point out that the highest amounts of vitamin C, among all the products that we examined, can be found in a bell pepper. Studying written sources, we found that bell peppers have more vitamin C than lemons. Also, quite a large amount of vitamin C can be found in oranges, garlics, and onions.
