The project “Having a lot of exchange student Have more values” had many steps to consult the problems which we wanted to study including planning how to do the project, searching the information after we had done the experiment, analyzing the result from the experiments and comparing the efficiency from the experiment. We gathered the data, made conclusion and wrote a report, made the products and made a presentation board. Throughout the period our members had received suggestion, cooperation and assistance from many people. They always encouraged us, examined our work and corrected our writing until it was finished. We really appreciate all the help everyone gave us when we did this project.
