项目摘要

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学引入中小学环境教育中，我们对中小学教师对土壤的兴趣和对土壤学术语的了解进行了调查。结果表明，教师对土和土壤的概念比较感兴趣，对教材中有关土壤的词汇和概念比较熟悉，如粘粒、土壤pH值、土壤保水能力等。但是，研究结果也表明，他们对土壤学中的农业术语，如土壤的三个空间、土壤的团粒结构、土壤的离子交换作用和缓冲作用等知之甚少.我们发明了在森林、草地和田野中观察到的理解、碎屑结构和复合颗粒的意义的教材。在环境教育培训中，小学、初中和高中教师用教材进行了土壤三种相和土壤离子交换的模拟实验。土壤离子交换效应模型实验对教师有很大的吸引力，因为它可以扩展到酸雨、石灰和洗涤剂对土壤的影响模型.这份报告是关于土壤观测和实验的教材。
