雾霾会危害人类呼吸系统的健康。你知道呼吸系统包括哪些器官吗?我们平时是怎样呼吸的呢?想要大口自由呼吸,离不开右面这些呼吸器官的帮助。一起来制作一个人体胸腔模型,简单模拟呼吸系统的工作吧。你需要:1个大可乐瓶,1个大气球和2个小气球,1块橡皮泥,1根吸管,几根橡皮筋,1把剪刀,1卷胶带,1把美工刀。第一步:将可乐瓶的下半部分切掉。在可乐瓶的瓶盖儿上开一个和吸管一样粗的孔。 Haze can endanger the health of the human respiratory system. Do you know which organs are included in the respiratory system? How do we usually breathe? Wanting to breathe freely can not be without the help of the right respiratory organs. Work together to create a human chest model, a simple simulation of the respiratory system. You need: a Coke bottle, a balloon and two small balloons, a plasticine, a straw, a few rubber bands, a pair of scissors, a roll of tape, a knife. First step: cut off the bottom half of Coke bottle. Make a hole that is as thick as a straw on the bottle cap.
