一个凸透镜、一张普普通通的纸,一束灿烂的阳光,当它们携起手来,会给我们演绎出怎样的精彩呢?科学老师健步走上讲台:“今天我们来做个实验。大家带上凸透镜,再拿上一张纸,到走廊上来。我们用凸透镜把阳光聚在纸上,看看有什么神奇的发现。”科学课总是带有神秘的色彩,凸透镜难道能让阳光给纸镶上金边?心动不如行动。我们四人一个小组,带着纸和凸透镜直奔走廊。灿烂的阳光给走廊的每一处角落都铺上了薄薄的金地毯,我们 A convex lens, an ordinary paper, a beam of bright sunshine, when they join hands, will give us deduced what wonderful? Science teacher walked to the podium: “Today we have to experiment. We bring a convex lens, then take a piece of paper, to the corridor up.We use the convex lens to sunshine on the paper, to see what magical discovery. ”Science class always with a mysterious color, convex lens can make Sun set in Phnom Penh paper? Echocardiography action. We are a group of four, with paper and convex lens straight corridor. Bright sunshine to the corridor every corner of the shop are covered with a thin gold carpet, we
