(九年义务教育初级中学化学教科书)第53页有氧气吹肥皂泡的实验,与教科书配套的教师教学用书第97页有对该实验改进的建议。但在实际操作时,总为能否用尖嘴导管或整齐断口的胶管顺利吹出很满意的肥皂泡而担心。我们在教学实践中设计制作了一种简单的起泡器,氢气流对之一吹
(Nine-year Compulsory Education Junior Middle School Chemistry Textbook) Page 53 Experiments with oxygen-blown soap bubbles. There are suggestions for improving the experiment on page 97 of the teacher’s teaching book that is provided with textbooks. However, in actual operation, it is always possible to use a needle-nozzle conduit or a well-broken hose to smoothly blow out satisfactory soap bubbles. We have designed a simple bubbler in the teaching practice.
