 note = {In this research, the materials for visualising Physical soil by means of color reaction were taught to 122 primary school, 103 middle school and 110 university students. The following results were obtained: 1) A high percentage of the subjects gave the response that fixing a piece of test cloth was troublesome, when asked about their impressions in collecting soil. 2) Their usual response after the experiment of detecting soil was that they were surprised at heavy soiledness just after one day's lapse.
