一、实验方案评价题例1某化学兴趣小组的六名同学分别设计如图1实验装置拟做验证质量守恒定律的探究实验。他们称取等质量的装置(连同药品),通过必要的简单操作(其中E需要点燃)使相关物质发生化学反应后,再放到原天平上称量,看天平能否保持平衡.请你为他们评价: First, the experimental program evaluation example 1 a chemistry interest group six students were designed as shown in Figure 1 experimental device to verify the quality of conservation law of inquiry experiments. They weighed the equivalent mass of the device (along with the drug) and made the chemical reaction of the relevant substance through the necessary simple operation (where E needs to be ignited) and then weighed it on the original balance to see if the balance could maintain balance. They commented:
