摘　　要：探究式学习在化学实验教学中占有非常重要的地位,为培养学生动手动脑等多方面能力,新课程改革对中学化学实验教学提出新要求,使得探究性实验和验证性实验的学习与教学在化学教学过程中的比重持续增加,传统的实验教学存在着实验装置复杂、操作繁琐等诸多不足。对教材中传统的Cl2制备及其化学性质的实验进行优化和完善,将Cl2的制备和其化学性质验证的实验装置设计为一套密闭的、简便的、易于操作的装置,实验步骤简单,药品用量少,实验过程连续可控,实验现象明显,装置中气球和注射器的使用还增加了实验的趣味性。Inquiry-based learning plays a very important role in chemistry experiment teaching.In order to cultivate students’practical and mental abilities,the new curriculum reform puts forward new requirements for middle school chemistry experiment teaching,which makes the proportion of inquiry experiment and confirmatory experiment learning and teaching continuously increase in the process of chemistry teaching.The traditional experiment teaching has exposed many shortcomings,such as complicated equipment and complicated operation.Optimize and improve the traditional teaching design in the preparation of Cl2 and chemistry experiment,the preparation of the Cl2 and the verification of the properties of the chemical experiment device integration is a set of simple airtight device,the experimental operation simple drug dosage,less continuous controlled experiment,the experimental phenomenon is obvious,use of the balloon and syringes also have increased interest in the experiment.
