Designing simple and feasible experiments with the least facilities for teaching the concepts of high school chemistry in the country

The purpose of this study is to design simple and feasible experiments with the least facilities for teaching chemistry concepts in schools of Iran. In this research, some experiments have been used to teach some of the concepts of chemistry in textbooks of the tenth and eleventh grades of high school. The design of experiments in this study was done by using the least available facilities to illustrate that even in the most deprived areas of the country, chemistry can be taught by conducting experiments in order to deepen students' level of learning. Also, due to the importance of conducting experiments and practical activities in students' learning and its application in chemical industries, students should not be deprived of this necessary excuse due to lack of facilities and chemicals. To do this, it is necessary for teachers to participate in in-service courses to learn the design of simple experiments with the least facilities and to use these experiments in their teaching.
