鸡蛋是同学们十分熟知的东西,以有关鸡蛋的知识为背景创设试题,同学们会感到十分亲近,充分感受到化学与生活的紧密联系,进一步增强学好化学的信心。现撷取几例加以说明,供大家参考。例1 小强在化学课上知道了蛋壳的主要成分是碳酸盐,决定制一个“无壳鸡蛋”送给妈妈。他应从厨房中选择鸡蛋和下列哪种物质( ) Eggs are very familiar to the students and they create questions on the basis of knowledge about eggs. The students will feel very close, fully feel the close relationship between chemistry and life, and further enhance the confidence of learning chemistry. Here are a few examples to illustrate for your reference. Example 1 Xiaoqiang knew in chemistry class that the main component of eggshell was carbonate and decided to make a “shellless egg” for mom. He should choose the eggs and which of the following substances from the kitchen ()
