In 2022, "Scientific Reporter+Exploring Fangshan" launched the first game into the magical chemistry and fireworks world

On June 26, the first event of "Scientific Reporter+Exploring Fangshan" in 2022 was successfully held. The event invites the professor of chemistry and journalism of Central South University and the "Ten Thousand Talents Plan" of the Central Organization Department to be selected as an expert Xu Hai. Fireworks Discovery: The Bright Starry Sky Chemical Magic Magic "leads students into the magical world of chemistry and fireworks.

"Detective Conan" is one of the most popular Japanese anime works in China. Although the content of the story is fictional, many details have very rigorous scientificity. Professor Xu Hai used the story of "In the Message of Revenge" as the starting point to explain the principle behind the fireworks: the color of the fireworks is attributed to the ion flame response in the firework. Spectrals, different metal ions can produce different flames.

Professor Xu Hai also tells the historical development and practical application of fireworks. While firework brings pleasing beauty, it also brings environmental pollution and fire safety hazards. It is necessary to attract attention from the society. Promoting environmentally friendly fireworks is an effective solution for the effect of environmental protection. one.

Start with interest, stimulate curiosity

In 2022, a practical interview and exchange with experts on the line on the line became one of the priorities of the activities of the small journalist. This live broadcast event not only combines the anime story scene of "Detective Conan" and the analysis and introduction of the characters, but also invite the participating young journalists to "what use for learning" and "scientist spirit" around chemistry related knowledge, In -depth exchanges with the lecturer.

In addition to interviews opposite the scientist line, this year's Fangshan reporter's activity also incorporated "refueling! The small answer" science popularization knowledge compete link, and consolidated the knowledge points in the expert science report. Why do most of fireworks are yellow "and other content not only pay attention to examining the daily accumulation of students, but also a summary and refinement of the popular science live content, bringing a new experience to junior high school students with beginner chemistry. The interactive answering session also designed picture questions -a person who covers her ears to avoid fireworks, which has aroused the dangers of scientific journalists on fireworks. It is a divergence of thinking. Through the design of the link, it not only enriches the content of the activity, but also effectively works. It is also effective. Improve the observation ability, expression ability and good at thinking and inquiry ability, and achieve the closed loop and optimization of the effectiveness of science popularization, thereby achieving the purpose of "starting from interest and stimulating curiosity".

Interview and interaction, people "remember bitterness"

During the interactive process, scientific reporters proposed: "When you are in junior high school, do you feel that learning is annoying?" "How does the subject that the teacher interested in the junior high school has a influence on the later learning life?" The most practical? "" What is the use of learning? "The topics of the topic communicated with Professor Xu Hai.

Professor Xu Hai combined with his own learning and work experience that although the learning process is hard, the joy after getting achievements is enough to make people "remember bitterness". Speaking of specific discipline learning, Professor Xu Hai said that although he was born in chemistry, he liked to study history lessons "rich historical and cultural knowledge can develop people's vision and provides different angles for scientific research, so there is no one of them. The course course is unhelpful. I hope that students have a more objective understanding and understanding. "

Seek truth and pragmatic, and remove the scientific "fog"

When the little reporters asked the topic of "scientist spirit", Professor Xu Hai quoted the famous sentences of "the truth only one" among Conan, and explained to the little reporter's understanding of the spirit of "seeking truth and pragmatism". He believes that the spirit of pragmatic is not only the character that scientists must have, but also the quality that students should adhere to it, which helps the development of good learning habits.

Professor Xu Hai told his students about his story in scientific research: formaldehyde is a chemical element with a small molecular weight, which means that it is difficult to "capture" like air. In order to study a coating that can remove formaldehyde, they It was verified with a variety of methods and finally rely on the latest technical means to achieve it. This tells us that many factors will interfere with the accuracy of scientific research. Eventually, the fog was opened and found the truth.

Netizens from the Beijing Science and Technology News APP, broadcasting, and today's headlines, together with scientific reporters from Liangxiang No. 4 Middle School in Fangshan District, Beijing, watched live broadcast activities online, and interacted with Professor Xu Hai. Over 210,000.

After 6 years of accumulation and continuous innovation in Fangshan Science reporter activities, it has successfully tapped a group of outstanding science and education resources in the district, established a team of scientific reporters, aggregated the youth groups, learned scientific knowledge, adopted news events, and participated in scientific activities. One of the youth science activities with brand characteristics.

In 2022, the "Scientific Reporter+Exploring Fangshan" event will be further promoted on the basis of previous years. The online popular science activity combines the "double reduction" requirements and starts with scientific interests. The experts and teachers in the science popularization field are invited to improve the comprehensive ability of scientific writing, observation, expression, and exploration of young people through lectures and interactive questions. It will lead small journalists into more popular science education bases, venues, national key laboratories, etc., pay attention to the cultivation of practical ability, and improve the comprehensive news literacy.
