在幼儿园里,饭前便后洗手已是幼儿养成的一个雷打不摇的习惯,但在洗手过程中,我发现一个问题:幼儿在洗手时,把水龙头打开,手上的脏物、细菌便会沾到水龙头上,当幼儿认认真真把手洗干净去关水龙头时,脏物、细菌又沾到了他们手上。这样,手是洗干净了,但在关水龙头时,却又一次被“污染”了。而且水龙头是公用物品,每天幼儿洗手都必然用它,这样易形成循环污染。 In kindergarten, washing hands before and after meals is an unscrupulous habit that young children develop. However, during the process of washing my hands, I found a problem: when children wash their hands, they turn on the faucets, dirt in their hands and bacteria It will touch the faucet, when the child earnestly wash the handle to close the tap, the dirt, bacteria and their hands stained. In this way, the hand is washed clean, but once in the off the tap, but once again “contaminated”. And the faucet is a public good, wash their hands every day are bound to use it, so easy to form a circular pollution.
