The toy car is equipped with an electric motor，Only then can one run，今天咱们要制作one款没有电机的小车，But it can also run，Do you believe it?？“Windsail vehicle”，
Why can he run without an electric motor？我们带着疑问one起去探究其中的奥秘！Windsail vehicle是在帆The ship的基础上改进发明的模型车。It uses natural wind force as its power source，The driving speed and the area and Angle of the sails、风force及风向、The weight of the vehicle body is closely related to its resistance。The windsail vehicle consists of a body、It is composed of an axle and a sail。Its technological principle is：The sails are driven by the natural wind，Convert wind energy into mechanical energy and transfer it to the wheels，The wheels roll and move by overcoming the frictional resistance of the ground。现在新款的Windsail vehicle我们加了one个新功能，Magnetic repulsion，one起做实验吧.
The technological model mainly refers to the land,The sea,Empty model.The integration of technological model activities and competition,动手和动脑为onebody,It is deeply loved by a large number of teenagers,Its main function is also to cultivate the comprehensive practical skills and high quality of teenagers.Therefore,At the turn of the century.Deepen reform,大force提倡素质教育的新形式下,积开展Science and Technology model activities,It is an effective measure for implementing quality-oriented education.
one Broaden one's horizons 丰富知识
Science and Technology model activities具有丰富的知识sex,Take the nautical model for example:During the making of nautical models and the process of navigation,学生可以"UnderstoodThe ship为什么会漂浮 The ship是怎样保持稳定sex的 螺旋桨为什么产生动force The ship怎样跑得快 "Titanic"Why didn't they sink immediately after being hurt and why couldn't they avoid the iceberg ……If one delves deeper,Students will come into contact with radio-controlled transmitting and receiving machines;"Understood(Or master)force,Density,"Gravity",Pressure,Magnetic field,The ship的构造,The structure and principle of an engine,Radio,Selection of materials……A lot of knowledge.There are many of them here"Textbook"Knowledge that is not available above but is often needed in life.This further inspires students on what other techniques are inspired by animals,One can imagine boldly,并做one个科技模型吗 Some think of dragonflies and planes,鱼形联想到鱼雷等并能制作one些简易的飞机模型等.In this way, students will be exposed to it in the science and technology model activities,Apply all kinds of knowledge,A lot of book knowledge has been supplemented,It broadened students' horizons,It has enriched students' extracurricular life,同时"Understood了更多的知识.
two Cultivate logic,思维能force
Science and Technology model activities,要求所有参与者在思维方法上要有辨证sex,整bodysex和严格的sex."Though a sparrow is small,All the internal organs are complete".The small technological model is big,A real car,The ship,飞机按one定比例的缩小制作;它是one个整body,牵one发而动全身.
one架比赛留空时间的模型飞机,Both have to go through two stages: high-speed climbing and low-speed gliding,Adjustments to the climbing stage,主要是地拉force线和两半翼扭曲后的迎角大小的调整.Location,机翼和平尾的安loading角及方向舵虽对飞机爬升的姿态也有one定的影响,But the changes in these parts,又直接影响着模型滑翔阶段的sex能,Therefore, during the design and adjustment process,Consider,这两个阶段不同的受force情况和解决办法.For example"In the car,The ship,The strength of materials in the design and production of aircraft models,The selection of stiffness and weight is very careful,从two者中选one佳方案.Therefore,Science and Technology model activities,在思维方法上要求青少年具有辨证sex,整bodysex,sex,否则one个小小的失误,便会使制作出的科技模型sex能变差甚至报废.
It can be seen that a person's initial thinking begins with actions.The thinking characteristics of students are mainly in the form of concrete and figurative thinking,Thinking cannot be separated from images and actions,Students are in the operation activity,You should keep your eyes open,Get your hands dirty,You still need to use your brain to think,Speak out,使外部的操作过程与内部的wisdomforce活动中的辨证sex,整bodysex,sex等有机结合起来,This effectively promoted the development of their thinking.
three 培养良好的习惯
Science and Technology model activities有利于塑造学生良好的个sex,Cultivate students' strong willpower and pioneering spirit,And be meticulous and patient,Form a rigorous attitude towards doing things, etc.
1,The arrangement time.Students are confronted with schoolwork and various interests,Specialty cultivation,都需要one定的时间和精force,学生合理The arrangement time才能做到井井有条,Busy but not chaotic.
2,See things through from beginning to end.Nowadays, most students are only children,Afraid of hardship and lacking perseverance in doing things,Often give up halfway,If they choose activities that involve both hands-on and brainwork by themselves,让他们自己去想方设法来完成one件科技模型作product,兴趣又会高涨one些,因为他们都爱玩动force玩具,Approach the method from this perspective,也会使他们慢慢克服制作过程中惰sex,And those who persevere in completing their masterpieces .This thus cultivated in them the habit of seeing things through from beginning to end.
3,Collectivist spirit.同学们one起设计,one起制作,one起比赛,Help each other from it,Compare with each other,Learn from each other.这样便培养了学生们的Collectivist spirit.Make students have others in their hearts,Learn how to get along with others.In this way under the conditions of a socialist market economy,才能与别人共创one番伟大的事业.像居里夫妇那样关起门来熬沥青的年代已经one去不复返了.Nowadays, society needs the cooperation of a talent group like the Apollo moon landing program to transform the world,Create the future.
four 激发学生探索科技领域的兴趣
one个家或发明家,There is no doubt that they have developed a strong interest in the things he loves,Then explore it,Study it,后在那one领域取得丰硕的成果.如今我们对学生进行科技模型的制作和组loading,让他们"Understood动force的形成,浮force的产生,Magnetic field的影响等,For their future interest in conducting research and exploration in this field,And lay a solid foundation,It also sowed the hope of success.
To sum up:积开展Science and Technology model activities,It is to implement quality-oriented education,Cultivate students' morality,wisdom,body,beauty,Labor development,Effective measures for cross-century workers and successors with comprehensive qualities;Actively carrying out science and technology model activities is the implementation,"Implementation《Several Opinions of The State Council of the Communist Party of China on Strengthening Popularization Work》Mental and fitness program,Implement what was proposed at the 15th National Congress of the Communist Party of China"Rejuvenate the country through science and education"Effective measures of strategy.
