在一次科学领域活动中,我就植物的各部位名称和植物生长所需条件进行了提问,孩子们对答如流。在此基础上,我做了进一步的提问:“那植物是怎样喝水的呢?”大家异口同声:“是通过根吸收的!”“你是怎么知道的呢?你有什么好的方法可以证明吗?”只见孩子们一片茫然,都皱起了眉头。金金同学的发言打开了沉寂的局面:“我在一本书上看到,植物就是由根吸收水和营养的。” During a scientific activity, I asked questions about the names of plants and the conditions needed for plant growth, and the children answered the question. On this basis, I made a further question: “How does the plant drink water?” “We all speak in unison: ” is absorbed through the root! “” How do you know? What do you have Good way to prove it? “I saw the children dazed, all frowned. Kim’s classmates’ speech opened up a quiet situation: ”I saw in a book that plants absorb water and nutrients from roots.“ ”
