化学是一门以实验为基础的学科。化学考试为了有利于选拔具有学习潜能和创新精神的考生,而化学实验能力和探究能力是学习化学的必备能力。所以在新课改下重视学生化学实验能力的培养是非常重要的。现就《氯气的性质》为例谈谈体会。课本中有五个演示实验,分别是收集一瓶氯气展示颜色、状态、气味的物理性质的实验;氯气溶于水的实验;铁丝、铜丝分别在氯气中燃烧的实验;氢气在氯气中燃烧的实验;验证氯气是否与水反应的实验。我觉得应该做如下调整较为合理。氯气有毒,每个实验都 Chemistry is an experiment-based discipline. Chemistry examinations In order to facilitate the selection of candidates with learning potential and innovative spirit, chemistry experiment ability and inquiry ability are essential for learning chemistry. So in the new curriculum reform emphasis on students ability to cultivate chemical experiments is very important. Now on the “nature of chlorine” as an example to talk about experience. There are five demonstration experiments in the textbook, which are the experiment of collecting the physical properties of a bottle of chlorine to show the color, state and smell; the experiment of chlorine in water; the experiment of burning wire and copper wire respectively in chlorine; the burning of hydrogen in chlorine Experiments to verify whether chlorine reacts with water. I think the following adjustments should be more reasonable. Chlorine is poisonous, every experiment
