一、利用生活中化学激起学生学习欲望在我们的生活当中,我们会接触到很多有关化学知识。比如妈妈给我们做又白又香的大馒头,它就是用乳酸菌来发酵制成的。做馒头的过程中面有可能会发酸了,这时我们就可以用面碱来中和,经过酸碱的中和,做出来的馒头松软可口没有异味。再比如我国有的地方用腐烂物提炼沼气,然后把沼气收集起来供我们做饭用,这也使用了化学知识,提炼气体,气体燃烧做到的。我们常用毛巾擦脸,毛巾会发黄发硬,这时我们用小苏 First, the use of chemistry in life arouse students’ desire to learn In our life, we will come into contact with a lot of knowledge about chemistry. For example, my mother gave us a white and fragrant bread, which is made of fermented lactobacillus. In the process of baking bread may be sour, then we can neutralize with the surface base, after acid-base and, made out of bread is soft and delicious no smell. Another example is where some parts of our country use biogas extraction of decay, and then collect the biogas for cooking, which also uses the chemical knowledge, refining gas, gas combustion to do. We often wipe the face with a towel, the towel will be yellow hair hard, then we use small Su
