这是一个看似普通的纸盒,如图1,但当你把一支笔放人纸盒中时,发现笔不见了.拿出这支笔仔细观察,笔是完整无缺的,难道这是一个“魔盒”吗?1.设计实验实验目的:应用平面镜成像特点设计玩具.实验材料:正方体纸盒一个,没有边框的平面镜一块(平面镜能刚好沿着纸盒的对角线放入)、剪刀一把、笔一支、双面胶带、贴纸(最好带有对称性图案).2.实验步骤(1)在纸盒的外侧和内侧分别用双面胶带贴上贴纸.贴好后,在纸盒的侧面和顶 This is a seemingly ordinary paper box, as shown in Figure 1, but when you put a pen in the paper box, I found the pen disappeared. Take this pen carefully observed pen is intact, is this A “magic box ” 1. Design Experiment Experiment Objective: Design the toy by the application of the plane mirror imaging.Experimental materials: a square cube, a flat mirror without a border (the plane mirror can be placed just along the diagonal of the carton ), A scissors, a pen, double-sided tape, stickers (preferably with a symmetrical pattern) .2 experimental steps (1) in the carton on the inside and outside, respectively, with double-sided tape affixed stickers.
