Yangtze River ** Wuhan Client December 30 (Reporter Guo Lixia Correspondent Chen Junping) Light and shadow recruitment order, see the world through the small hole;The laser relay rallies and listens to the command ...... lightWhen light and shadow intersect with scientific experiments, this is definitely the most special way to open up physics learning. On the afternoon of December 29th, the "Physics Experiment Creative Competition" of Wuhan No. 49 Junior High School started the journey of light.
Grade 8 students formed teams as a class to design the competition equipment, complete the pinhole imaging and laser target relay race, and feel the charm of physics in the process of exploring the truth.

Zeng Xiangsheng, the head of the school's eighth-grade physics preparation team, introduced that the knowledge in the fourth chapter of physics is the phenomenon of light, and in order to cultivate students' ability to understand, apply and practice knowledge, the school designed this creative competition. Students work individually or in small groups to make equipment using raw materials such as cardboard boxes and mirrors in their spare time, referring to the content of textbooks and online materials. Students must give full play to their imagination and creativity if they want to transform abstract knowledge into vivid models.
At the event, the students brought their own hand-made equipment to complete the small hole imaging and laser relay target shooting competitions. According to the time taken by each team to successfully shoot the target, the judges judged that the team with the shortest time won, and selected three awards respectively: the best shooter, the boy chasing the light, and the messenger of the light.

There are self-made brackets under the mirror, cardboard base, and what is more amazing is that the angle of the mirror can be adjusted to 720 degrees, pitch adjustment, horizontal adjustment, which is convenient to move and stablePhysics teacher Bai Yang was full of praise for the reflector device designed by the 803 class Ji Ang group.
Physics teacher Yan Hong said that the seemingly simple device is actually very knowledgeable: from the selection of materials to the pruning and production, the distance between the small hole and the object, the angle of the reflector and the fixed ......Each of these items requires students to think and try repeatedly in practice to deepen their understanding of knowledge.
Ma Weihao's group of Class 809 won the first place in the laser relay race, Ma Weihao said: "We have assigned tasks through group discussions in the early stage to ensure that every member can participate in it, fix the laser source, spray the light, adjust the angle of the plane mirror, accept the light, and every step requires perfect team cooperation." Physics is not difficult, physics is beautiful. ”

Wan Haixue, Secretary of the Party Branch of Wuhan No. 49 Junior High School, said that in order to actively respond to the national "double reduction" policy and implement the education policy of the Qingshan District Education Bureau on "reducing the burden of the curriculum, improving quality and efficiency", the physics preparation team of the second junior high school carried out student science and technology innovation competitions in the optimization design of homework, broadened the process evaluation, met the differentiated learning needs of students, and boosted the improvement of students' ability and literacy. It is hoped that this activity can improve students' interest in learning physics, encourage children to learn, learn to cooperate, and be brave in innovation.
