针对传统的钠与水反应实验中的不能同时收集氢气及点燃等不足之处,我研制出“新型Na与H2O反应可自动收集可点燃一体化演示实验教学仪器”并应用于中学化学课堂实验教学,不但能减轻化学教师进行相关实验教学的负担,大大提高课堂演示实验的效率,更能通过直观观察有效激发学生学习化学的兴趣,帮助学生理解相关反应,培养学生的创新意识和实践能力。
In response to the traditional reaction of sodium and water can not be simultaneously collected hydrogen and igniting shortcomings, I developed a “new Na and H2O reaction can automatically collect lit demonstration of experimental teaching equipment ” and used in secondary school chemistry class Experimental teaching can not only relieve the burden on experimental teaching of chemistry teachers, greatly improve the efficiency of classroom demonstration experiments, but also effectively stimulate students ’interest in learning chemistry through visual observation so as to help students understand relevant reactions and develop students’ innovative awareness and practical ability .
