1. To introduce studies of soil into environmental education in junior high school and high school from scientific view, we maked a survey of interest to soil and knowledge of terms on soilscience for teachers. This result shows that many teachers have interested in earth and soil, and known words in teaching materials and notion of soil very well, for example clay, pH of soil, and the ability to keep water in soil. However, the result also shows that they have little known about agricultural terms of soilscience, for example three pacies of soil, crumb structure, ion-exchenging effect and buffer action of soil.2. We invented teaching materials to understand, crumb stracture and a signification of compound granule that were observed at forest, glassland and fields.In training of environmental education, teachers of primary school, junior high school and high school experimented with teaching materials that were used for modeling on three facies of soil and ion-exchange of soil. The experiments that was used for model of ion exchanging effect of soil had great appeals to teachers, because it could develop to models of effect on acid rain, spreading lime and detergents to soil.3. This report shows teaching materials for observation and experiments on soil.

1.为了从科学的角度将土壤研究引入初中和高中的环境教育，我们调查了教师对土壤的兴趣和对土壤学术语的了解。这一结果表明，许多教师对土壤和土壤感兴趣，并对教材和土壤概念非常熟悉，如粘土、土壤的pH值、土壤的保水能力等。然而，调查结果也表明，他们对土壤学的农业术语知之甚少，例如土壤的三层结构、土壤的离子交换效应和土壤的缓冲作用。在环境教育培训中，对小学、初中、高中教师进行了土壤三相模拟实验和土壤离子交换实验。用来模拟土壤离子交换效应的实验对教师有很大的吸引力，因为它可以发展成酸雨效应模型、向土壤中喷洒石灰和洗涤剂的模型。这份报告展示了土壤观察和实验的教材。
