对铁与水蒸气反应实验改进的评价与优化

Evaluation and Optimization of Reaction Experiment of Iron and Water Vapor

为对铁与水蒸气反应实验进行改进，寻找达到高效课堂教学的最佳实验方案，在其他文献的基础上，对实验条件中的吸水材料进行了对比实验研究，并对实验效果评价，优化设计得出最佳实验方案：用水晶泥作提供水蒸气的吸水材料，并增加冷凝水蒸气的装置。

In order to improve the reaction experiment of ferrous powder and water vapor and find the best experimental program to achieve efficient classroom teaching, this paper compared water-absorbing materials, evaluated the experiment results, and optimized the design to obtain the best experimental program on the basis of other literatures： Using the crystal mud as the wa- ter-absorbing material to provide water vapor, and adding the water vapor condensation device.
