有趣的反射光
光学是一门有趣的且令人惊奇的学科，我们可以通过一些简单的小实验来探索光线的特性！本周，我们邀请到了5A班的郑昕恬、朱佳韵、董佳萱、李婉月四位Science King科学研究员，为大家呈现了光的反射实验和会跳舞的反射光两个实验！接下来，让我们一起看看小研究员们是如何探究光的吧！
Optics is a fascinating and amazing subject. We can explore the properties of light through some simple experiments! This week, we invited four Science King researchers from Class 5A: Zheng Xintian, Zhu Jiayun, Dong Jiaxuan, and Li Wanyue, to present two experiments on light reflection and dancing reflected light! Now, let’s take a look at how our young researchers investigated light！
哇！小研究员们太厉害了，不仅找到了反射光，还利用声音让反射光在屏上跳起了舞！你们也赶紧跟着一起做起来吧！
Wow! These young researchers are incredible. Not only did they find reflected light, but they also used sound to make the reflected light dance on the screen! You should try it yourself, too!
实验准备
1.实验一材料准备：激光笔（使用注意安全，不可以直射别人的眼睛！）、镜子、透明方形杯、牛奶、滴管、水。
2.实验二材料准备：纸杯、镜子、激光笔（使用注意安全，不可以直射别人的眼睛！）。
1. Materials for Experiment 1: laser pointer (be cautious, do not point it directly at anyone’s eyes!), mirror, transparent square cup, milk, dropper, water.
2. Materials for Experiment 2: paper cup, mirror, laser pointer (be cautious, do not point it directly at anyone’s eyes!).
实验步骤
实验一
Experiment 1
1.将镜子粘在方形杯子底部，加入半杯水；
2.向水中滴入1-2滴牛奶，搅拌均匀；
3.用激光笔照射水中的小镜子，观察实验现象。
1. Stick a mirror to the bottom of the square cup and fill it halfway with water.
2. Add 1-2 drops of milk to the water and stir well.
3. Shine the laser pointer onto the mirror in the water and observe the results.
实验二
Experiment 2
1.准备一个纸杯，在纸杯底部粘上一枚小镜子；
2.用激光笔照射镜子，在墙壁或地面（屏）寻找反射光点；
3.对着被子发出足够响的声音，观察反射光点的变化。
1. Prepare a paper cup and stick a small mirror at the bottom.
2. Shine the laser pointer onto the mirror and look for the reflected light spot on the wall or floor (screen).
3. Make a loud enough sound toward the cup and observe the changes in the reflected light spot.
小任务
看完这个实验，你是不是已经迫不及待地想试一试了！当然你也可以实践关于光的其他小实验！请把你的实践操作通过以下方式分享给我们大家哦！
After watching the experiment, are you eager to try it out? Of course, you can also conduct other small experiments related to light! Share your practical work with us in the following ways:
1.录制实验视频，发送至邮箱hwflscienceking@126.com或本班科学老师钉钉。实验视频包括材料准备、实验过程、介绍原理等部分，实验视频以班级+姓名+作品名称进行命名。
2.科学老师会依据收到的视频资料，经一学期的积累，学期末将评选属于世外的HWFL Science King实验小达人，颁发奖状，优秀作品还可参加省级科学影像项目竞赛，快快行动起来吧！
1.Record your experiment video and send it to hwflscienceking@126.com or to your science teacher on DingTalk. The video should include materials preparation, experiment process, and explanation of principles. Name your video with your class, name, and the title of your work.
2.Based on the submitted videos, at the end of the semester, science teachers will select the HWFL Science King Experimental Stars of the term and award certificates. Outstanding works may even participate in provincial science video competitions. So, hurry and get started!
