Seeing that the situation was not good, Director Zhu hurriedly took the children to the playground outside the classroom. There was a slide that the children loved the most.
When Leilei saw the slide, he was really excited. He slid down from the slide twice, and Leilei's face was flushed. Director Zhu and the kindergarten teachers could finally breathe a sigh of relief. However, they soon had to get nervous again.
After only seeing Leilei slide down the slide, he suddenly ran towards his mother, grabbed his mother's little hand and pulled her to the slide. Because the child's language organization ability was insufficient, he could only draw his mouth, hands and feet with his fingers: "Over, come down-"
As a mother, Ning Yunxi and his son had a good understanding of each other. He quickly understood what his son was asking, saying, "You ask why you slipped down from above, right? This is about the principle of sliding slides. Slides were only available in the 1970s, which is equivalent to something about ten years ago. The principle comes from gravity and friction. Do you see that the surface of the slide is smooth?"
Under the guidance of my mother, Leilei's little palm was slapped on the slide, which was slippery.
"A smooth surface can reduce friction between objects and help gravity slide downward. In the future, there is another slide skateboard that is curved, which involves a principle called the fastest curve. Assuming that the height of these two slides is the same, you and another child like you are sliding down from the apex of the slide at the same time. Which child do you think will arrive at the ground first?" Ning Yunxi asked his son new questions while answering questions. This is a teaching habit she formed as a teacher, which is conducive to inspiring children's exploration and curiosity in the depths of science.
Leilei's little hands grabbed his hair, and his mother's problem looked very difficult, so he looked at his father with help.
Meng Chenhao was as confused as he heard it and didn't understand.
Principal Zhu and two kindergarten teachers unknowingly wanted to find a place to hide. The child's mother was hundreds of times better than their kindergarten teachers. They just didn't understand the mathematical physics principles in Ning Yunxi's mouth. If the child suddenly turned to ask them these teachers, they would probably be shameless.
"Okay." Ning Yunxi said to her son. Anyway, she never likes to give her son a direct answer, and said, "Let's ask your second uncle and ask your second uncle to make a model for you. You will know if you do an experiment."
Leilei's second uncle is a super science and science master. Listening to his mother's words, Leilei agreed very much. He patted his palm and was anxious to go home to find the answers to his second uncle.
Seeing that her son was interested in science, Ning Yunxi was also happy. When she came to her senses, she immediately realized that she was embarrassed. She took her son to see the kindergarten, and wanted to make her son interested in the kindergarten, not to teach her son here.
"Yes, I'm sorry, Director Zhu." Ning Yunxi quickly turned around and apologized to the teachers standing there.
Director Zhu hurriedly said, "It's okay. Teacher Ning's lesson has also benefited us a lot."
"I, I teach high school, don't understand kindergarten teaching." Ning Yunxi waved his hand and said.
