拆解与重组

观察由少量部件组成的物体可以被拆开并做成新物体，理解这些部件依然存在。

Observe that an object made of a small set of pieces can be disassembled and made into a new object, understanding that the pieces still exist

学习证据 / Evidence

• 解释拆开物体并重新组装时，用的是同样的部件，只是排列方式不同。
• 描述物体看起来不同了，但部件本身没有改变。
• 举出一个日常例子，说明重新利用材料可以做成新东西。

• Explain that taking apart an object and rebuilding it uses the same pieces in a new arrangement
• Describe how the pieces themselves don't change even though the object looks different
• Give an everyday example of reusing materials to make something new
