Practice Study of the Creative Teaching Materials Using New Material and New Energy for Junior High School Technology and Manufacturing Classes

In this research，我们开发the shape memory alloy engine car and passive walking toy as a new material and new能量教学材料（energy teaching material）：这一研究的主要目的是发现introducing的可能性the teaching material in a junior high school as a class of technology education actually.In the SMA引擎car,shape memory alloy and pulleys are used as a main prime mover of the car. the引擎可以旋转使用该属性，形状的记忆，也可以把它放在一个热的位置上water. The most characteristic part is The engine. To make The temperature difference between upperlower pulleys as much as possible，引擎part is leaned about 45 from a chassis.因为热的temperature difference between hotwater and room temperature is the most important to make the engine rotate as fast as possile . thepassive walking toy walks down a gentle slope due to the gravity force and the instability ofequilibrium. For using the toy as a teaching material, we measured the cycle period of its walking，and analyzed the motion. and then，the influence of various elements in its walking was considered.To找到可能性as ateaching material,the engine car ans toy were actually introduced in the class of technology education in junior highschool as a practical teaching. Through the manufacturethe students can get through the experience of difficulty, joy to use tools and learn not onlythe way of manufacturing it but the knowledge of a metal属性，way of using tools and its names。

In this research, we developed the shape memory alloy engine car and passive walking toy as a new material and new energy teaching material. The main purpose of this study is to find the possibility of introducing the teaching material in a junior high school as a class of technology education actually.In the SMA engine car, shape memory alloy and pulleys are used as a main prime mover of the car. The engine can rotate using the properties that shape memory alloy can turn into straight-shaped as it gets in a hot water. The most characteristic part is the engine. To make the temperature difference between upper and lower pulleys as much as possible, the engine part is leaned about 45゜ from a chassis. Because the temperature difference between hot water and room temperature is the most important to make the engine rotate as fast as possible.The passive walking toy walks down a gentle slope due to the gravity force and the instability of equilibrium. For using the toy as a teaching material, we measured the cycle period of its walking, and analyzed the motion. And then, the influence of various elements in its walking was considered.To find the possibility as a teaching material, the engine car ans toy were actually introduced in the class of technology education in junior high school as a practical teaching. Through the manufacture, the students can get through the experience of difficulty and joy to use tools and learn not only the way of manufacturing it but also the knowledge of a metal properties, the way of using tools and its names.
