由树荫下地面上的许多圆形和非圆形光斑提出了5个光学探究问题,利用废旧的食品筒,制作了小孔成像仪,并将学生分5个小组进行了实验探究.通过猜想假设、设计实验、收集数据、分析论证,分别得出相应的结论,总结出小孔成像的条件和5个特点,同时对实验中的4个意外发现进行分析与归纳,还指出了进行实验观察时必须注意的3个环节.
Five problems of optical inquiry were proposed by many circular and non-circular spots on the ground under the shade, the hole imager was made by using the waste food canister, and the students were divided into five groups to conduct the experiment and explore. Hypothesis, experiment design, data collection, analysis and argumentation, draw corresponding conclusions respectively, summarize the condition and five characteristics of pinhole imaging, at the same time, analyze and summarize the four unexpected findings in the experiment, and also point out the experimental observation Must pay attention to the 3 links.
