html On June 26, the first event of 2022 "Little Science Reporters + Exploring Fangshan" was successfully held. The event invited Mr. Xu Hai, a professor of chemistry and journalism at Central South University and an expert selected for the "Ten Thousand Thousand Thousand People Plan" of the Central Organization Department, to give a lecture "Detective Conan" to young science journalists in Fangshan based on the popular animation work "Detective Conan" among teenagers. "Detective Conan: Fireworks Exploration: The Chemical Magician in the Brilliant Starry Sky" leads students into the magical world of chemistry and fireworks.
"Detective Conan" is one of the most widely disseminated Japanese animation works in China and has the greatest influence on young people. Although the content of the story is fictional, many details are very scientific. Professor Xu Hai used the story "In the Message of Revenge of Death" as a starting point to explain to the students the principle behind the production of fireworks: the colorful colors of fireworks are attributed to the ion flame reaction in the fireworks, which is essentially the generated by the electron transition in the outer layer of the metal. Emission spectrum , different metal ions can produce different flame colors.
Professor Xu Hai also talked about the historical development and practical application of fireworks. While fireworks bring pleasing beauty, they also bring environmental pollution and fire safety hazards, which need to be paid attention to by the society. The promotion of environmentally friendly fireworks is an effective solution. One of the options.
Start with interest and stimulate curiosity
In 2022, conducting online face-to-face practical interviews and exchanges with experts has become one of the focuses of the activities of young journalists. This live broadcast event not only combines the "Detective Conan" animation story scenes, analysis and introduction of the characters, but also invites the participating young reporters to discuss "the use of learning" and "scientist spirit" around the relevant knowledge of chemistry. Had in-depth exchanges with the lecturer on other contents.
In addition to online face-to-face interviews with scientists, this year’s Fangshan Little Journalists event also incorporated the “Come on! Little Answer Man” science knowledge contest, which consolidated the knowledge points in experts’ science reports, such as “Which ingredients do not belong in fireworks?” Contents such as "Why Most Fireworks Are Yellow" not only focus on testing students' daily accumulation, but also summarize and refine the popular science live broadcast content, bringing a new experience to junior high school students who are new to chemistry knowledge. The interactive question-answering session also designed a picture question - a person covering his ears to avoid fireworks, which triggered young science reporters to think about the dangers of fireworks. It is a kind of divergence of thinking. Through the design of the session, it not only enriches the content of the activity, but also effectively It improves the observation ability, expression ability and thinking and inquiry ability of young reporters, and realizes the closed loop and optimization of the effectiveness of science popularization reports, thus achieving the purpose of "starting from interest and stimulating curiosity".
The interview interaction made people "remember the hardships and think about the sweetness"
During the interaction, the young science reporters asked: "When you were in junior high school, did you find studying very annoying?" "The subjects that the teacher was interested in in junior high school had a great impact on later study and life. What impact has it had?” “Which subject knowledge is the most practical?” “What is the use of learning?” and other topics.
Professor Xu Hai said based on his own study and work experience that although the learning process is hard, the joy after achieving the results is enough to make people "remember the pain and think about the sweetness". When it comes to specific subject studies, Professor Xu Hai said that although he majored in chemistry, he liked to take history classes when he was in school. "Rich historical and cultural knowledge can broaden people's horizons and provide different perspectives for scientific research, so there is no one This course is useless, and I hope that students will have a more objective understanding and knowledge. "
Seeking truth and being pragmatic, clearing the "fog" of science
When young reporters asked about the topic of "Scientist Spirit", Professor Xu Hai quoted Conan. The famous saying "There is only one truth" explained to the young journalists their understanding of the spirit of "seeking truth and being pragmatic". He believes that the spirit of truth-seeking is not only a character that scientists must possess, but also a quality that students should abide by and help develop good study habits.
Professor Xu Hai told the students the story of his scientific research work: Formaldehyde is a chemical element with a very small molecular weight, which means that it is as difficult to "capture" as air. In order to study a method that can remove They used a variety of methods to verify the formaldehyde coating, and finally relied on the latest technical means to achieve it. This tells us that many factors will interfere with the accuracy of scientific research. The spirit of truth-seeking and pragmatism requires us to abide by our true intentions and Don’t give up any detail, and finally clear away the fog and find the truth.
Netizens from Beijing Science and Technology News app, Yizbo, Toutiao and other platforms, together with young science reporters from Liangxiang No. 4 Middle School in Fangshan District, Beijing, watched the live broadcast online and interacted with Professor Xu Hai. Total broadcast The number of visitors exceeded 210,000.
After 6 years of accumulation and continuous innovation, the Fangshan Science Reporter Activity has successfully tapped a number of excellent science and education resources in the region, established a team of science reporters, and gathered young people to learn scientific knowledge, write about news events, and participate in scientific activities, becoming One of the youth science activities with brand characteristics of Fangshan District .
The 2022 "Little Science Reporter + Exploring Fangshan" activity will further innovate on the basis of previous years' activities. Online science popularization activities combine the requirements of "double reduction" and start with scientific interests. Experts and teachers in the field of science popularization are invited to improve young people's comprehensive abilities in scientific writing, observation, expression, inquiry, etc. through lectures and interactive questioning, and offline interview practice activities We will lead young reporters to visit more popular science education bases, venues, state key laboratories , etc., focusing on the cultivation of practical abilities and the improvement of all-round news literacy.
