Pay attention to family, pay attention to family education, and pay attention to family style.
The "lazy cup" hides the principle of "Lenz's law", and the "airflow box" contains a magical one....In this small science museum, all kinds of interesting phenomena hide a wealth of scientific knowledge.
Eggs float in the water, and colorful "snowflakes" ...... float out of the water glassIn this "magical" world, science becomes fun and efficient.
The "solar wings" rotate slowly above the "space station", and the refraction of the glass creates a beautiful ...... of flowers in full bloomIn this space full of exclamations, the little inventors become shining protagonists.
The shining protagonists who open the door to the magical world are the students of Changchun Nanhu Experimental Zhonghai Primary School, who water the seeds of science in their hearts with their whimsical ideas, making this winter vacation mysterious and fulfilling.
They are "gold medal docents".
What is it like to bring the "Science Museum" to the campus? Ren Baiqi, a fifth-year student at the school, said there was a secret here.
What's the secret? Look at his unearthings.
3，2，1！As the countdown began, the three cylinders of the science and technology exhibit "Lazy Cup" fell vertically from the same height. "Why do three cylinders fall at the same height at different speeds? Ren Baiqi showed interesting scientific phenomena, explained the principles of the experiment, and threw questions to everyone, and the junior students who were watching made bold guesses. Then Ren Baiqi explained the principle of "Lenz's law", and the students suddenly realized, "Through the explanation of scientific and technological works, my interest in science has been stimulated, and I usually learn some physics knowledge on the Internet, and I want to explore the physical principles behind some phenomena in depth." Ren Baiqi said.
In the small science and technology museum, there are more than 20 professional science and technology exhibits such as the "Lazy Cup", and Ren Baiqi is a part-time docent for one of the exhibits. "We moved the exhibits of the Provincial Science and Technology Museum into the campus, so that students can see and touch the amazing scientific knowledge. Wang Lin, vice principal of the school, introduced that the school is equipped with senior students as docents for each exhibit, revealing the physics knowledge involved in vivid language, "We hope to cultivate everyone's sense of exploration in this way, and internalize and expand scientific knowledge, so as to become the children's innovative consciousness engraved in their bones." ”
They are "little inventors".
You only need one Zhonghai coin to experience the fun of the express space station", "How is this cosmic circular orbital pinball machine operated", "Can I try this 'water press'", the children sighed in the school's "Science and Technology Innovation Home", and a dazzling array of scientific and technological works came into view. The students were happily holding Zhonghai coins and happily experiencing the interesting inventions made by their classmates.
The inventor of the work "Space Station" is Li Zhennan, a student from the fifth year class of the school, who generously introduced his work to the students, "My work is made of paper shells, bamboo sticks and plastic, and batteries and wires are installed in it, and I created it based on the model of the Chinese space station. Li Zhennan turned on the switch of the "space station" while explaining, and the "sun wings" on it rotated, attracting the attention of other students.
Yang Bo, the principal of the school, introduced that these small inventions are made by children and parents, and in the process of making them, they have improved their hands-on ability, learned interesting scientific knowledge, and the colorful inventions have also made the children's whimsical ideas find an "exit", "I hope that the children will always adhere to the desire to explore the unknown world, and be a person who is willing to try and dare to create." ”
They are "masters of magic".
Colorful magic potions, crystal clear artificial snowflakes, gas ...... steaming in the test cupA dizzying array of science experiments are taking place in the Science Magic Room, and the exclamations and cheers of the students add a more mysterious color to the magical experiments.
Wang Qianzi, a student from the second class of the third year of the school, put the egg into a measuring cup filled with a transparent liquid, and the phenomenon of the egg floating on the water attracted other students to watch. "It's because I add salt to the water to make it denser, and that's why the eggs are lifted. Wang Qianzi explained the principle of the experiment to everyone. "That's why people can float in the Dead Sea. ”
On another table, beautiful snowflakes continue to gush out of a glass, "which is made by adding water-absorbing resin and water, and you can add different colors to them." Liu Ruiwen added paint to the water while introducing, and after a while, colorful snowflakes sprinkled all over the table, and the students on the side applied for the experiment.
These intuitive and magical phenomena make science more interesting and efficient, and there are different scientific knowledge behind the wonderful and interesting phenomena. Seeing that the children were stimulated by interesting scientific experiments to explore, Yang Bo sighed that on the rich platform, the boring and distant science on weekdays is entering the children's world, and in the vivid activities, the children's awareness of scientific and technological innovation and curiosity are slowly established. **Changchun**.
