钻研教材中的实验,可以为我们提供更广阔的研究空间,可以培养我们观察事物的能力,通过实验现象的解释可以使我们的思维更灵活,通过实验方案设计、实验过程、实验记录、实验结果的分析,并对实验中的反常现象进行深入探究,可以培养我们科学的学习态度,为将来的发展提供有力的保障。下面是根据教材中浓硫酸性质实验设计的一个研究性实验。设计思路及解答技巧都为大家提供了一个研究教材的平台。一、题目某研究性学习小组为研究 Cu 与浓 H_2SO_4的反应,设计了如附图所示的实验探究方案(装置中的固定仪器和酒精灯均未画出)。
Studying the experiment in teaching materials can provide us a broader research space and can cultivate our ability to observe things. Through the interpretation of experimental phenomena, we can make our thinking more flexible. Through the experimental design, experimental process, experimental records, experimental results Analysis of the abnormal phenomena in the experiment in-depth exploration, we can cultivate our scientific learning attitude for the future development to provide effective protection. The following is a study based on the experimental design of concentrated sulfuric acid in the textbook. Design ideas and tips for all we provide a platform for research textbooks. First, the title of a research study group to study the reaction of Cu and concentrated H_2SO_4, designed as shown in the experimental study program (device fixed instruments and alcohol lamp are not drawn).
