上海版《自然常识》五年级课本《怎样才能使水蒸发快》实验安排是首先在两片圆形铁片上分别滴上相同的水滴,然后进行加热和不加热的对比,空气流动量大与小的对比,液面大与小的对比。实验的步骤是分别加热、增强通风量,增加液面积,通过实验使学生知道温度越高,风越大,液面积越大,水蒸发得越快。 Shanghai version of “natural common sense” fifth grade textbook “How can the water evaporate quickly” experimental arrangement is the first drop in the two pieces of circular iron were the same drop of water, and then heating and non-heating contrast, large and small air flow The contrast, big and small liquid contrast. Experimental steps are separately heated, increased ventilation, increase the liquid area, through experiments so that students know the temperature is higher, the wind is larger, the larger the liquid area, the faster the water evaporates.
