根据大纲的要求和培养人材的需要,我校从一九八O年开始就成立了各年级的化学兴趣小组,积级开展课外科技活动。一、组织兴趣小组,确定活动内容每学年开始,都在初三、高一、高二年级中组织化学课外兴趣小组,每组有1-2名教师作指导,有20到30个学生参加。多数是学习成绩较好的学生,但也有少数是学习成绩较差,而对活动有兴趣的学生。各组都有明确的目的要求及活动计划,一般每周活动一次。初中活动以选做课本上的化学实验为主;高中则进行实验基本操作的训练,以及完成部分演示实验和一些趣味性的实验。如利用浓硫酸的脱水性制“黑面包”;利用红磷和白磷在一定条件下可以互变的性质制“奇异的灯管”;利
In accordance with the requirements of the syllabus and the needs of cultivating talents, our school has established chemistry interest groups of various grades since 1980, and has accumulated grades to carry out extracurricular science and technology activities. 1. Organize an interest group to determine the content of the activity. Each year, beginning in the academic year, there are organized extracurricular interest groups in the third, senior, and senior grades. Each group has 1-2 teachers for instruction and 20 to 30 students participate. Most of them are students with good academic performance, but there are also a few students who have poor academic performance and are interested in activities. Each group has a clear purpose requirement and activity plan, which is usually performed once a week. Junior high school activities are mainly selected for chemical experiments on textbooks; high schools are trained on basic experimental operations, and some demonstration experiments and some interesting experiments are completed. Such as the use of concentrated sulfuric acid dehydration system “black bread”; the use of red phosphorus and white phosphorus under certain conditions can be intertwined nature of the system, “Strange lamp”;
