Chemistry is a strange science that combines mathematics, biology, physics, geometry, astronomy, and probability. In other words, whether chemistry is nature or nature cannot be answered. We have read and heard many times that science should be put into practice, but how should this goal be achieved? The purpose of this research is to link science and nature, and then guide the interest and concern of students towards chemistry course. By designing a purposeful experiment, in this research, chemistry is put into practice in its real sense, and with the connection of science and nature as well as the experience of conducting research and experiments by students, their sense of concern and love for nature is strengthened, and their minds are directed towards practical ideas and creativity to solve the problems of the surrounding world. The research method is quasi-experimental and descriptive, in which the conditions of Lake Urmia and the water behind the dam are simulated for one month in a small laboratory scale. The results of this research show that after one month and measuring the remaining water in the samples under study, due to the colligative properties in Lake Urmia, the rate of evaporation of salt water is lower than that of tab water and pure water, and the ability of the lake to store water in it is higher than that of surface evaporation.
