* The sound of a group laughing from the male cat group as they studied science class at the city's famous high school. Male cats often play with each other and annoy science teachers and female cat students. Because male cats think that studying science is a boring subject for lazy students like them. In particular, it deals with complex mathematical formulas for solving problems. As for the female cats , they are excellent students and enjoy studying real science more than social science. Groups of female cats discuss solutions from a distance from the moon. Suddenly the Spiky cat is playing with a rocket model while the cat teacher explains how to solve the distance to the moon. The Spiky cat joked that looking at the moon the teacher draws on whiteboard it look like a cake egg. "Hey guys, do you think so, if we imagine that the rocket I'm holding looks like an ice cream spray, and I'm going to shoot it over cake eggs to eat, that's really delicious." The other male cats friends laughed and Spiky's words compare the jokes.

* The teacher saw this and called Spiky to fix the problem on the whiteborad. When he looks at the exercise he gets sad because he doesn't know how to solve it. Then he turned to ask his friend for help. Each of his friends turn to look at the desk and hold a book to cover their faces. Because they also don't know how to solve this exercise. Meanwhile, the female cats laughed at Spiky. when the teacher, asking him to lift one leg and raise his arms, stands near the teacher's desk until the end of class. At the end of the course, teacher said that next week there will be a flying model rocket launch competition for high school cat students, with the participation of representatives of all the outstanding science students from top schools across the country. Also inside is the name of our school. Therefore, the principal chose our class to represent the competition. Because the scores of female cat students are ranked number 1 in science for two consecutive years. However, due to the needs of the competition, students are required to participate in the same group of 12 to 15 students. so I decide to choose you all. I didn't want to recruit other students to join our class. Because their lessons are late than us and need more time to re-teach. I will select Mimi as the team leader to lead the competition project. Male cat students create model rockets and test flights. "What if we don't attend," Spiky said. The teacher says if the male cat does not participate , does not have any extra points to add to the semester exams. The male cat students heard this and were very happy, unlike the cat students whose feelings like have trouble and headaches.before the day of completion, they spent a week working together to build a miniature rocket after completing the course study. the mimi team leader distributes the functions among the members of the group. She told the male cats to start building the rocket according to the model they had made before. she says this time we need the rocket to reduce the weight which can increase the speed and should also put lightning protection panels on the top of the rocket. After she discussions with her members, she handed over a rocket paper model the male cats.

* Spiky told his friends about how to build a model rocket to his friends. First, some rocket basics. These basic parts are the same for each rocket model, Launch lug: This is how the rocket connects to the launch rod to make sure your rocket goes straight up. Never launch without a properly attached launch lug. Fins provide stability during flight. Fins will come in different configurations and are either made of plastic or balsa wood. Balsa wood fins are much more difficult to attach and keep aligned while drying. Rockets are reusable assuming they are properly launched and recovered. Rocket engines are one-time use only. The thrust of the rocket comes from the engine pushing up against the engine mount. Lighter rockets will use a streamer instead of a parachute for the recovery system. The parachute comes out when the engine releases an ejection charge to pressurize the body tube and pop out the parachute. Recovery wadding is needed between the engine and parachute to prevent this ejection charge from damaging the parachute. At this point, we will reduce some materials that make our rocket non-heavy and we will build a rocket that can be recycled and reused for future times.

* After spending time together doing it. Suddenly, Spiky feels that the time they spend doing something useful together is truly the happiest thing. And the disciples realized they weren't stupid at all. they regret not paying attention to the teacher who explains the lesson and always find excuses to avoid problems. The Teacher checking their model rocket. He was quiet a bit and he said I'm so proud that you can build rocket model success. " when you hit the book to do something, you will receive what you have done. "This is an important lesson in changing your lazy personality. Don't neglect the lessons you learn in the classroom, for they are the bridge that will take you to shore. And practical work requires a lot of attention to be successful. When you come together to do something, you will realize that time is the most memorable and precious moment for you. Male cat students apologize to the teacher and promise to study hard to relearn to be as good as female cat students. The female cat students enter the laboratory, they are surprised and very happy to see the male cats succeed in building it.

* after that they talk, they have to test their rocket flight speed. the teacher wondered if they were now testing the model rocket, which rocket they would use in competition. spiky told the teacher , we built a rocket that can use it many times not like a rocket before. after talking, they go to the schoolyard to test it. Mimi Cat explains how to fly rocket to male cats. This is a good time to discuss Newton's Third Law. As the engine ignites, the action is the hot gases being pushed out the bottom of the rocket and the reaction is the rocket launching upward. For the rocket to move, the thrust from the engine must be greater than the weight of the rocket. During the flight, the engine continues firing for a few more seconds, and the aerodynamic forces of lift and drag act on the rocket. Once the fuel runs out, the rocket starts to slow down from the weight and drag forces. A maximum height is reached, and students can measure this height using an Estes Altitrack and simple. The rocket starts to fall, and the "ejection charge" from the rocket engine pushes the parachute out. We may notice some smoke which is intended to help you see the rocket in the sky. Once the rocket hits the ground, time to recover! With mild wind conditions, our rocket should lander within 100 feet away. We can replace the engine, and launch the rocket again. They managed to fly their rocket faster and faster than the national competition records. on the day of the competition, the last compilation of the last round which made them nervous because they saw their partner group rocket at a speed similar to them but suddenly lighter in the air hit their partner group rocket which made it fail. therefore they won first place in this competition. These are the best ideas of leader Mimi who said to male cats use lighter protective panels on top of the rocket. they went to celebrate pizza party together and the female cat be open minded to be friends as the they accepts the ability of the male cat.
