On October 21, 2015, faculty members and students of SUSTC held a science lecture in SUSTC Experimental Primary School. Named “International Year of Light Science Lecture on Optics”, this lecture was given to the pupils of the first and second grades in SUSTC Experimental Primary School.

At the beginning of the lecture, Mr. Tang Xiaoyong, Vice Principal of SUSTC Experimental Primary School, threw out a question to the children: How is the world if there is no light? The kids responded actively, showing great interest in the knowledge of light. Then, Mr. Luo Dan, Assistant Professor of SUSTC, gave the children a brief introduction to the Optical Society (OSA) as well as the members of SUSTC OSA Student Chapter.

During the exciting interactive experiment time, Chen Wei, a senior student of SUSTC, detailedly and vividly explained various principles of the experiments presented by Lan Zhaojue who is another student of SUSTC. After observing a light beam through the soybean milk and pinhole imaging and playing the hand shadow game, the children learned that light travels in a straight line, which is the fundamental principle of optics. When the kids were surprised at the bent chopsticks in the glass with water, SUSTC’s students explained the reason for refraction by showing the deflection phenomena at different angles of a red light beam and a green light beam in front of meniscus lens.

Through this activity, the pupils felt the happiness brought by knowledge and learned about how to put knowledge into practice. The teachers and students of SUSTC Experimental Primary School welcomed SUSTC to bring more such activities so as to influence the children with SUSTC’s spirit of innovation as well as its idea of education.

This science lecture was led by Mr. Luo Dan, Assistant Professor of the Department of Electrical and Electronic Engineering, SUSTC, and held by SUSTC OSA Student Chapter.
