在初中生物学新课程中,有关光合作用的实验主要有两个:一是“探究光与绿色植物的关系”;二是“探究光合作用的场所”。在第一个实验中,教材推荐使用的植物是天竺葵,在第二个实验中,教材推荐使用的植物是银边长春藤。事实上,天竺葵很难找到,而用银边长春藤做此实验,现象并不很明显,所以这两个实验几乎成了生物实验的摆设,失去了其学生实验的价值。而我发现,扶芳藤(有非银边的和银边的,第二个实验使用银边的)是做这两个实验的好
In the new junior high school biology curriculum, there are mainly two experiments related to photosynthesis: one is to explore the relationship between light and green plants, and the other is to explore the place of photosynthesis. In the first experiment, the plant recommended for use in the textbook was geranium. In the second experiment, the recommended plant for the textbook was iridium ivy. In fact, geranium is hard to find, and the experiment is not very clear with silver ivy ivy. Therefore, these two experiments have almost become the decoration of biological experiments and have lost the value of their student experiments. And I found that Euonymus fortunei (with non-silver edge and silver edge, the second experiment using silver edge) is good for these two experiments.
