探究光与影的秘密,从生活中最常见的真实情境的光现象引发思考,认识光源的概念,通过自主选择有结构的实验材料进行实验,验证光在空气中的传播路线,进而发现光途径水和透明肥皂中的传播路线也是直线的。利用自制教学具完成影子游戏,探究影响影子性质的相关因素,发现影子形成的原因和影子的相关秘密。拓展“光与影”相关知识在医学、军事、工程上的应用,扩大学生的视野,给学生创造了轻松的学习环境,给学生的科学学习带来了快乐的享受。
Explore the secrets of light and shadow, from the light of the most common real life situations in life triggered thinking, understanding of the concept of light source, through independent choice of structured experimental materials to experiment, verify the light in the air of the transmission line, and then find the light way water and Transparent soap in the transmission line is straight. Use self-made teaching tools to complete the shadow game to explore the impact of the nature of the shadow of the relevant factors and found the shadow of the formation of shadow and related secrets. Expand the application of “light and shadow” related knowledge in medicine, military and engineering, expand students ’horizons, create a relaxed learning environment for students, and bring happiness to students’ scientific learning.
