19. Happy Science (Part 1)

There is a science and technology competition in the science and technology museum, and the task of setting the questions is given to the children. Lin Shuang told the children about this, and everyone was very happy. Only Zhang Yi looked absent-minded, and he stayed like this for several days. Tian Tian and Adili felt strange and secretly followed Zhang Yi, wanting to know what Zhang Yi was doing. After struggling for a long time, the truth finally came out. It turns out that Zhang Yi is inventing something called a "lie detector". To the children's surprise, it can actually detect whether a person is lying. At this time, a boy who was making trouble appeared in the science and technology museum. He didn't listen to the explanations every time and just played. Zhangyi was very angry. He felt that if this continued, the Science and Technology Museum would become an amusement park instead of a place for learning. After discussing it with Tiantian, Zhangyi decided to use a lie detector to determine whether people really love science. Zhanyi had an argument with the boy over the lie detector test, and the two fought excitedly. Lin Shuang and the dean rushed to the scene and stopped the two children. The dean announced on the spot that he would withdraw his identity as a young volunteer from Zhanyi, and Zhanyi returned home frustrated.

20. Learning Science with Happiness (Part 2)

Everyone felt very sad about Zhan Yi, but they didn’t know how to bring Zhan Yi back. After much deliberation, several children decided to use a mass signature campaign to persuade the dean to spread their wings and come back. The children split up. Tian Tian and Adili were responsible for asking for various things from Zhanyi, while the Ouyang brothers and sisters were responsible for persuading Lin Shuang and the dean. Everything went smoothly, and in the end, the dean finally agreed to let Zhan Yi come back. Everyone is happy that the wings are back. Several children worked together to complete the competition questions. The science and technology competition was held as scheduled, and the troublesome boys were among them. Zhanyi asked Adili to secretly make some moves and became the boy's examiner. But what Zhanyi never expected was that the boy could answer every question perfectly and finally got the first place. After the competition, Zhanyi apologized to the boy. Unexpectedly, the boy was embarrassed and said that it was because of the fight with Zhanyi that he got angry and started learning science. Unexpectedly, he actually fell in love with science in the end. Both children laughed.
