Abstract In order to help students to build a general knowledge of the acid-base property of salt solution, this paper designed an experimental lesson which contained some modern information technologies. First, a micro-video made by the software ‘Camtasia Studio’ was shown in the class, then the students imitated to guess the acid-base property of these two solutions and design experiments to verify their guesses. During this period, the teacher took photos of the students doing experiments with an ipad and showed those pictures with the computer projection by AirPlayer, an application from iTools at the appropriate time, so as to promote a further analysis. The use of micro-video shortened the experimentation, increased the classroom efficiency and was also convenient for students to review this lesson. Taking candid photographs and real-time projection helped to have a distinct review of the experiment by freeze-framing and magnifying the experimental phenomena. Students could also realize the importance of solution selection and experience an ordinary process of scientific inquiry by designing and practicing the experiment on their own.
