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.
