物体与材料
Objects vs Materials

- 举出同一物体由不同材料制成的例子（如塑料杯、玻璃杯）。
- 通过观察和触摸来辨别某个物体是由什么材料制成的。
- Explain the difference between an object (e.g. a chair) and the material it is made from (e.g. wood)
- Give examples of the same object made from different materials (e.g. plastic cup, glass cup)
- Identify what material a given object is made from by looking at and touching it
