i always feel that tofu bought in the market is not hygienic,cut off or eat impurities in the mouth?worrying about food safety is worse than making your own healthy tofu.for experimental drugs,clearly state the polymerization state (stable, liquid, gas or solution); used to figure out the name of the experimental equipment,and require correct use; the language used for experimental operations should be detailed and concise; for experimental phenomena,from "the sea, land, and air" (to produce gas, change of liquid color, solid dissolution, etc.),the color should be expressed correctly; for the experimental conclusion,accurate description,and reused for experimental purposes.experimental teaching helps to stimulate students' interest in learning,it can also help students learn to form basic concepts,acquire basic knowledge.otherwise, many accidents will happen.there are also some experimental operations performed in a different order,will lead to different experimental phenomena.at the same time,this also helps to cultivate students' observation ability,获得熟悉的实验技能,培养学生从事实中寻求真理的科学态度,提高学生的科学探究能力,它在化学教学中起着举足轻重的作用。
