初中化学学科与实际生活联系紧密,很多教学内容来自于生活,如环境污染问题、金属锈蚀问题。在本节课的开始,利用双板的网页插入功能,插入苏州环保局网址,给学生提供一种新的查询空气质量的方法,并通过系统放大镜功能,让班级大部分同学都能看到苏州实时的空气中二氧化硫的数据,引起学生兴趣,让学生关注环境,拉进学生与化学的距离。
Junior high school chemistry is closely linked with the actual life, a lot of teaching content comes from life, such as environmental pollution problems, metal corrosion problems. At the beginning of this lesson, using the dual-page webpage insertion function, you can insert the website of Suzhou Environmental Protection Bureau to provide students with a new way to inquire about air quality. Through the function of system magnifier, most students in the class can see Suzhou Real-time sulfur dioxide in the air data, aroused interest in students, so that students pay attention to the environment, into the distance between students and chemistry.
