通过钠与水反应产物推断，可学习到一种推断反应产物的重要科学方法，不仅可对前一章氧化还原反应和离子反应的知识进行应用、巩固与加深，也为后一章节学习非金属及其化合物等知识做铺垫。通过创新的实验装置收集生成的气体以及用点燃气泡的方式检验气体，能激发学生思维。也有利于培养学生学会在实验过程中观察实验现象以及合作探究学习。相较于以往钠的教学中教师直接讲述钠与水反应实验现象的原因，该教学设计能让师生参与设计实验来体验实验创新，更有利于培养学生科学素养。

Through the deduction of the reaction products of sodium and water ,an important scientific method to deduce the reaction prod-uct is learned ,which can not only be used to consolidate and deepen the knowledge in the previous chapter of redox reaction and ion reaction , but also lays the foundation for the study of the non metal and its compounds .It can stimulate students’ thinking and help to develop students’ learning to observe experimental phenomena in the process of experiment and cooperative inquiry learning through the innovation of the experi-mental device to collect the generated gas and the way to test the gas by lighting bubbles .Compared to the previous teaching of sodium that the teacher directly tells the reason of the phenomenon of the reaction between sodium and water ,this teaching design can let the students partici-pate in the design experiment to experience the experimental innovation ,and is more conducive to the cultivation of students’ scientific literacy .
