摘要
介绍了基于STEM理念下让学生自制电解水芯片的实验探究.学生观察芯片上的电解水现象,负极产生的氢气和正极产生的氧气体积比为2∶1.本实验简单、安全、环境友好,适宜于学生独立实验操作.此研究通过设置科学问题、强调学生探究、体验科研的全过程,激发了学生兴趣,培养了学生的创新能力.
This paper introduced students＇ experiment inquiry of preparation of electrolysis chip of water based on STEM concept, and students could observe the volume ratio of He and O2 （2：1） in the lab-on-a-chip. This experiment was simple, safe and environment-friendly, and was suitable for students＇ independent operation. This study stimulated students＇ learning interests, and developed the innovation ability of students by setting scientific questions, emphasizing students inquiry and making students experience the whole process of scientific research.
