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.

为了开发从小学到大学基础课程的各种学校的化学安全教育的教育内容，开发了实验室化学演示和教材。通过学校和大学的教育实践，对这些教材的有用性进行了评估。通过本研究，获得了以下结果。(1)关于有害气体的安全教育，选择二氧化氮作为教材。为使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，对这些教材的实用性进行了评价。(2)利用家用微波炉对无机水合物进行加热实验，作为一种新型的安全教育教材。通过比较五水硫酸铜和六水硝酸钴的加热过程，揭示了微波炉加热实验的危险性。(3)为了教学有毒有机溶剂的正确处理，开发了苯磺化反应的微型实验。通过在某中学学生实验室的应用，对该实验的实用性进行了评价。(4)针对学生实验室化学物质污染的情况，设计了一个以荧光为指示剂的中和滴定实验。通过在大学的教育实践，评估了实验的有用性。(5)通过收集各种教材，开发了化学品安全教育网页。
