《水珠从哪里来》一课是小学三年级科学(下)第三单元中的第5课.对于本课的学习,必须从第4课说起.学生们观察了冰块的融化过程,不仅发现了冰从固态变成了液态的水还发现了1盛冰的玻璃杯外壁和2塑料袋外壁上也有小水珠。对于这些小水珠的来源,学生一开始就有多种解释(或假设),并寻求证据以检验假设。学生们通过分析,检验假设的过程,将会获得更新的证据,从而,作出新的解释。 The Lesson 5 Lesson 5 of Lesson 3 of Science in Primary Three, for Lesson 3, begins with Lesson 4. Students observe the melting of ice cubes, Not only was it found that ice had changed from a solid to a liquid state, it also found a cup of ice and a small drop of water on the outer wall of the plastic bag. For the source of these small drops, students have multiple interpretations (or hypotheses) from the outset and seek evidence to test the hypothesis. By analyzing and testing the process of assumptions, students will receive updated evidence and thus make new explanations.
