实验目的：
研究平面镜成像的现象。
实验器材：
魔箱。
实验过程：
1、人站仪器侧面，将一枚硬币沿仪器上端的开口投下。
2、人再站仪器正面，观察发生的现象。
3、可从仪器侧壁，开箱取币。
探究问题：
1、为什么投币不见了呢？会发生怎样的现象？
2、玻璃镜为什么要固定成45度角呢？
实验结论与体会：
（以下由学生总结并交流，也可由教师引导得出。）
注意事项：
仪器内有玻璃镜子，实验时注意安全。
Magic box
Experimental purpose:
Researching the phenomenon of the plane mirror imaging
Experimental equipment:
Magic box
Experimental process:
1. A man stands at the side of the instrument, and insert a corn into the slot which is on the top of the instrument.
2. Then the man stands at the face of the instrument. Observe the phenomenon that will happen.
3. You can open the box to take out the coin from the side of the instrument.
Researching issues:
1. Why does the coin disappear? And what happened?
2. Why is the mirror fixed to 45 degree angle?
Experimental conclusions and the experience:
The followings can be concluded and discussed by the students, or guided to get by the teachers.
Caution:
There are mirrors in the instrument, so be careful when experiment.
