Summary of the summer physical activity class in 2019

In order to enrich students' summer life, in order to cultivate and establish students' interest and yearning for science, and to cultivate students' innovative spirit, practical ability and hands-on skills, the school organized a summer physics and chemistry interest class-activity class. The activity class is a supplement and improvement of the subject curriculum, and it can receive the effect of “killing the knife without cutting the firewood” and at the same time it is one of the carriers for implementing the elementary education. The students of this activity voluntarily enrolled, not limited to grades, aiming at the students' self-activities, through the students' main practice activities, promoting their main body spirit, hands-on practical ability and overall improvement of comprehensive elements. It is practical and open. The characteristics of autonomy and flexibility. It is not only conducive to cultivating students' hands-on practical skills, but also conducive to cultivating students' initiative to explore science. It is also an attempt to reflect the new physics curriculum concept. The activity class was very successful. The children were very interested and very interested. They all tasted the joy of success. As one of the participating teachers, the activity process is summarized as follows:
First, the time schedule
July 10th - July 20th, a total of ten days, two lessons per day
Second, the activity content
7,10 "Lead you into the physical hall" scientific lecture
7, 11 making a camera model
7,12 Making "Kongming Light"
7,13 making electric boats
7,14 "Cosmos and People" Popular Science Movies
7, 15 rest
7,16 making a water rocket
7,17 making a telescope
7,18 making a kaleidoscope
7,19 production assembly aircraft model aircraft
7,20 "Hey, how good I am" - the activity class shows three, the participants Liu Guangyan, Liu Wei, Hou Qingling, Wang Dexi four teachers and students more than 240 people four, event preparation
1. The hardware is prepared to make bamboo poles and white papers of Kongming lanterns, make electric motors for electric boats, make rubber plugs and valves for water rockets, make convex and concave lenses for telescopes, make plane mirrors for kaleidoscopes, and model airplanes. Students are not easy to buy or own. Materials that cannot be processed are purchased collectively by the school. This work is mainly carried out by Liu Wei and Liu Guangyan. The two teachers were very hard. In addition to taking the morning activity class, they braved the heat and continued to rush for several afternoons. They ran all over the corners of Kaifeng City and purchased these equipments for the smooth progress of our activities. The preparations have been fully prepared.
Tools such as cardboard, cans, beverage cans, foam plastics, fine iron wires, thin wires, absorbent cotton, and inflators, as well as scissors, paper cutters, pliers, transparent plastic, double-sided tape, etc. are provided by students.
2, software preparation
Mainly by me and Hou Qingling, in order to explain the production process and the brief physical principles, we have designed and produced courseware for almost every class, and it is hard to work through the big screen. In addition, we have to make samples first, in order to know how successful the students are, in order to clarify the production process, for which we work several times late into the night.
V. Activity Snapshots The production of the illuminating light on the side of the hole and the main points of production. After the explanation, the students were divided into four groups, four people's desks and together as their workbench, and then distributed equipment, the children began to work in full swing. Some of them take bamboo poles into a ring to make a bracket for the hole lamp. There are measurements of the ruler. Some use scissors to cut paper, and some take tape and paper seams. There are division of labor, cooperation, and sometimes quarrels. The sound came, because the most difficult thing to do with the kongming lamp is the top, a tube made of thin paper, which has neither support nor can you start from the inside. If you accidentally break the paper, you have to paste the top cover. It is too difficult for them to see through the wind. However, the children's interest has not been reduced. After repeated trials and arguments, they eventually overcome the difficulties. Many of the students' works are more beautiful than the samples of several of our teachers.
During the flight phase, on the open space in front of the classroom, the children’s expressions were as excited as the launch of the Chang’e-1 satellite, so expecting and a little nervous. When the alcohol of the first hole lamp was ignited, the scene was silent, and for a moment, the heat swelled the paper tube. When the feeling of the hand was obviously relieved, and the lift was slightly lifted, I tried to let go of the hand, and the hole light began. Slowly twisting the body rose, just as the cheers were about to ring, suddenly, it sank and fell. The top cover has a big hole. It turns out that the double-sided tape is degummed under high temperature baking. The children’s faces passed a trace of pity, and the more they wrote on their faces were still happy, because they saw the dawn of success after all. After experiencing this failure, no, it can't be called failure. It should be said that it was an attempt. Many students re-examined their works and strengthened the top cover. The next test did not take off two or three times, and the children were a little disappointed. The teachers and classmates gathered together to analyze the reasons, adjusted the weight of the fuel, and then I returned to the "launch field" with full expectation, lit, released, and the dramatic scene finally happened. It slowly rose, and a small wind blew. It squatted and rose. It crossed the wall of the school and rose to the height of the third floor of the school building. Suddenly, for some reason, its height. It has dropped a little, and everyone’s heart has to mention the eyes of the blind. After a while, it rose steadily, rising, flying higher and higher, flying higher and higher, until it was hundreds of meters high, the campus was full of joy, after which, the joyful sounds again and again. The joy of the children is not inferior to the joy of the designers when the No. 1 successful launch. I believe that the joy, the excitement and confidence brought by the moment of success, the children will remember for the rest of their lives.
Six, experience summary
1, carefully prepared, try to make.
2. Promote competition and encourage innovation. Because each student's intelligence and hands-on ability are different, the small productions made are very different, some are very fine, some are very rough; some are very accurate, and some have large errors. At this time, we will judge to encourage children to strive for perfection in their work.
3. Pay attention to the collection and display of the results of the activities. Success is proof of one's ability and the best reward for learning and labor. Through the collection and display of the results of the activities, students can see their achievements. Successful learning and activities produce a self-satisfied psychological experience and self-confidence. Continuous functionalization causes a cumulative change of various learning- related factors, allowing students to form relatively stable attributions, and to make the cumulative effects of success long-term and stable.
