项目摘要

Aiming at developing educational contents for chemical safety education at various schools from elementary schools to basic courses at universities, chemical demonstration and teaching materials at laboratories were developed. The usefulness of such teaching materials was evaluated through educational practices at schools and colleges. Through the present study, the following results were obtained.(1) As for the safety education concerning harmful gases, nitrogen dioxide was selected as a teaching material. In order to make students understand properties and safety treatment of nitrogen dioxide, two students' experiments of "fountain of nitrogen dioxide" and "chemical equilibrium in a syringe" were developed. The usefulness of these teaching materials was evaluated through education practice at our university.(2) As a new teaching material for safety education concerning heating experiments, a heating experiment of inorganic hydrates using domestic microwave oven was developed. It was revealed that the danger of the heating experiments using microwave oven can be recognized by comparing the heating processes of copper (II) sulfate pentahydrate and cobalt (II) nitrate hexahydrate.(3) A microscale experiment of sulfonation of benzene was developed for teaching the proper treatment of toxic organic solvents. By applying the experiment to students' laboratory at a high school, the usefulness was evaluated.(4) For introducing the pollution of chemical substances at students' laboratory, an experiment of neutralization titration using fluorescence as an indicator was developed. Through educational practice at the university, the usefulness of the experiment was evaluated.(5) A web page of chemical safety education was developed by collecting various teaching materials.

针对从小学到大学基础课的各类学校化学品安全教育的教育内容，开发了化学演示和实验室教材。这些教材的实用性是通过学校和学院的教育实践进行评估的。通过本研究，取得了以下成果：(1)在有害气体安全教育方面，选用二氧化氮作为教材。为了让学生了解二氧化氮的性质和安全处理，设计了“二氧化氮喷泉”和“注射器中的化学平衡”两个学生实验。通过我校的教学实践，评价了教材的实用性。(2)作为加热实验安全教育的新教材，开发了家用微波炉加热无机水合物实验教材。通过比较五水硫酸铜(II)和六水硝酸钴(II)的加热过程，揭示了微波炉加热实验的危险性。(3)建立了苯磺化微尺度实验，用于教学如何正确处理有毒有机溶剂。通过将该实验应用于某高中学生实验室，评价其实用性。(4)针对学生实验室化学物质的污染情况，开展了以荧光为指示剂的中和滴定实验。通过在校的教育实践，评价了实验的实用性。(5)收集各种教材，开发了化学品安全教育网页。
