生物学是一门实验科学,一切生物学知识都来源于对大自然的观察与实验。通过利用对空气污染敏感的苔藓植物,探究香水对生物影响的实验,学生在不断观察中发现问题。该实验可以让学生运用比较法对不同环境下苔藓的生长情况进行观察对比,亲眼见到环境污染对生物的危害,有利于学生锻炼观察分析能力和形成环保的意识。
Biology is an experimental science, all biological knowledge comes from the observation and experiment of nature. By experimenting with the effects of fragrances on the biology using the bryophytes, which are sensitive to air pollution, students find problems in constant observation. The experiment allows students to compare the growth of moss in different environments observed and compared, witnessed the harmful effects of environmental pollution on the biological, is conducive to students to observe and analyze the ability to exercise and the formation of environmental awareness.
