| Abstract: | An open experiment for middle and low grades students was developed. In the experiment, the ultrasonic extraction was used for extraction of the ultraviolet absorbent in peel, which involving in knowledge and operation of inorganic chemistry., analytic chemistry and organic chemistry. The experi- ment combined the single factor experiment and the orthogonal experiment. It is helpful to develop student＇ s experimental operation skills and ability to apply knowledge. |
