在学习了《大气的保温效应》这一教学内容后,为了加深学生对保温作用的理解,我们用实验来推证“温室效应”现象。然后通过学习有关文章和网上资料,拓展了相关的知识,了解温室效应的利弊。同时,联系实际,提出解决方案,强化学生的环保意识。一、“温室效应”的原理全球的地面平均温度约为15℃。可是,倘若没有大气,地球的地面平均温度应为-18℃。这33℃之差大体就是因为地球有大气,像一条被子一样,造成大气温室效应之故。宇宙中
After learning the teaching content of “Thermal insulation effect of the atmosphere”, in order to deepen the students’ understanding of the thermal insulation effect, we experimentally concluded the “greenhouse effect” phenomenon. Then through the study of relevant articles and online materials, expand the relevant knowledge to understand the pros and cons of the greenhouse effect. At the same time, contact with the actual, put forward solutions to enhance students’ awareness of environmental protection. First, the “greenhouse effect” principle The global average ground temperature is about 15 ℃. However, if there is no atmosphere, the Earth’s average ground temperature should be -18 ℃. The difference of 33 ℃ is generally due to the Earth’s atmosphere, like a quilt, causing the greenhouse effect of the atmosphere. In the universe
