初中物理課本第一册《气体的重量》《大气压》和《抽水机》这三节,我是作为一堂課来教的。这三节书实驗較多,要完成教学任务,必須做实驗。但我校只有一个抽气机,其他仪器都沒有。在这样情况下,我們找了一些代用的东西,把課本上的实驗都完成了。例如,要称量空气的重量,我們沒有課本上那样的球形玻璃瓶,怎么办呢?就用普通的酒瓶子来代替。 Junior Physics Textbook Volume I “Gas Weight” “Atmospheric Pressure” and “Pumping” These three sections, I taught as a lesson. These three books more experiments, to complete the teaching task, we must do the experiment. But my school has only one extractor, none of the other instruments. In this case, we find some alternative things, the textbook experiments are completed. For example, to weigh the weight of the air, we do not have a spherical glass bottle on the textbook. What to do? Instead of using a normal wine bottle.
