摘　　要：以CO_(2)与NaOH溶液反应无明显现象为切入点,引发质疑,展开探究,并进一步探究了NaOH溶液的变质情况;通过探究,复习了CO_(2)、NaOH、Na_(2)CO_(3)等物质的部分化学性质,建立了验证无明显现象的化学反应的思路和方法;渗透了变化观和微粒观,形成了一定的证据推理能力,培养了实证意识,引导学生经历了科学探究,发展了科学思维。Taking the no obvious reaction between carbon dioxide and sodium hydroxide solution as the starting point,it raised doubts,carried out inquiry activities,and further explored the deterioration of sodium hydroxide solution;Through exploration,we reviewed some chemical properties of carbon dioxide,sodium hydroxide,sodium carbonate and other substances,established ideas and methods to verify chemical reactions without obvious phenomena,penetrated the concept of change and particle view,formed a certain evidential reasoning ability,cultivated authentic evidence consciousness,guided students to experience scientific inquiry and developed scientific thinking.
