However, the scientific instruments are expensive and not easy to obtain, so most people can only the search the Internet for nanostructures photo or go to the library to find nano-book if they want to know the nano structure of some materials. The photo is flat and not easy to understand the 3D nano structure. Elementary school teachers usually use slides or animations to explain nano phenomenon. In the case of passive inculate knowledge and very few interactive operations, it is not easy to arouse the students motivation to take the initiative to explore the nano phenomenon in learning. In this study, the interactive teaching materials of butterfly effect of was designed using mobile devices or multi-touch Tablet PC technology to manipulate the butterfly wing for showing different magnification of its nano structure. The 3-axis acceleration sensor technology allows users to turn around a different view-point to make the butterfly wing show a different color. Students can understand the butterfly effect by the observation of nano phenomena as seen in the nature. In this study, a teaching experiment was conducted to investigate the learning effectiveness of students after using "The interactive teaching materials of butterfly effect". The experimental data were analyzed using the SPSS statistical software and a significant difference was found by comparing with traditional teaching method. The experimental results showed that "The interactive teaching materials of butterfly effect" could increase the effectiveness of learning. Through the system questionnaire survey, it was found that the "The interactive teaching materials of butterfly effect" can effectively increase students’ interest in learning.
