On June 7th, I went to Dawu Elementary School to conduct the teacher's science exhibition ability workshop in the field of natural sciences in primary and secondary natural sciences. The theme is optical. Although the theme is optical, it is different from the past. Elementary School's scientific teaching aids to university, because it can make a variety of, various shapes and colors. After reading the kaleidoscope we are prepared, the teachers must ask the teachers to make their own kaleida. Fighting into a square kaleidoscope. Although it is simple to say, it is actually difficult to do it after doing it. Especially when the 6 -piece lenses are put up, these six lenses are actually fixed only with tape, so if you accidentally stick to it, you will stick to it. Crooked, after the kaleidoscope is over, the experiment of polarizing tablets is mainly to observe the optical phenomenon of transparent tape and two polarizers. The principle of learning, the professor can only explain to the teachers, it is a bit difficult to deepen.
