In this paper, in order to increase students’ interest and understanding in class, we designed and conducted an education program that combines ICT with scientific experiments. A survey was conducted before and after the education to study the effectiveness of convergence education and the necessity of ICT convergence education. When water(H2O) is electrolyzed in an electrolysis experiment of water, oxygen(O2) gas is generated in the (+)electrode and hydrogen(H2) gas is generated in the (-) electrode. The water in the oxygen gas-generated test tube changed from neutral to acidic by hydrogen(H⁺) ions. At the same time, the water in the hydrogen gas-generated test tube is converted into basic by hydroxide(OH⁻) ions. However, students’ understanding of the experiment and interest in the class were low because existing scientific experiments alone could not confirm the decomposition process or chemical reaction of water molecules. Therefore, in this paper, an Arduino pH measurement sensor was used to measure the acidity change of water generated during the electrolysis experiment of water. In addition, by developing a convergence education program that visualizes the water electrolysis process as an animation using processing, the effect of convergence education on the understanding of the experiment was investigated. Using the convergence education program of this paper, the chemical reaction and decomposition process of water molecules occurring in the experimental process can be visually confirmed. In order to find out the effectiveness of the convergence education program, the attitudes and understanding of the experiments before and after the use of convergence program were compared through a survey. As a result of the survey, out of a total of 58 students participating in the experiments, the percentage of the correct answer to the question to answer the type of gas generated by electrolysis of water increased from 1.7% before the experiment to 48.3% after the experiment. In the ‘recognition’ and ‘interest’ sections, it was confirmed that students’ attitudes and understanding of the experiment increased. Through this paper, it is expected that it will be able to present new educational methods for coding and physical computing, which are becoming important through the 4th Industrial Revolution.
