%X In this paper, we present a demonstration for sublimation and we investigated the demonstration efficiency on students¡¯ conceptual understanding of sublimation. Demonstration is considered an effective strategy to teach intangible concepts and a way to increase students¡¯ enthusiasm for learning. We prepared a solution in which the surface tension was decreased using soap. This facilitated the formation of bubbles when dry ice was added. This provides a good environment for students to observation of sublimation. The demonstration improved students¡¯ understanding of sublimation.
