PPT制作精美；将氯的结构示意图与其性质联系起来，猜测氯可能具有的性质，再做实验验证，符合学生的思维认知特点。但是具体是做怎样的实验，没有展开说明，可以详细一点。
优点：PPT制作比较精美，增强了说课的效果；对每一环节的分析都比较合理。
不足：教学流程的讲解不够详细，缺少语速语调的变化。
清楚地说明教学实施的各个环节（情境引入、师生共同探讨化学性质、实验探究、课外延伸）。情境以氯气的化学史实，来引导学生来思考氯气的性质。不足就是没有提及课标对本节内容的具体.
对于教学地实施过程，清楚地说明了教学实施的各个环节，逻辑清楚；但是时间安排还不是很恰当，因为如果要让学生针对氯气与水的反应做一个实验探究猜想的方案的话，花费的时间可能会多一些，这样，整个一小节的内容讲下来时间可能会紧凑，更不用说还要有课堂习题。
