我利用寒假,制作了一个实验装置来验证吸烟对肺部的影响:
设计目标:
通过演示试验了解吸烟对身体的严重危害性。从而引导同学们开展“拒绝吸烟”、“劝戒行动”进行创新活动设计。在活动中知道自觉拒绝香烟,维护自己的权益、维护环境。
装置材料:
一个透明的瓶子矿泉水瓶(含盖子)、香烟、橡皮膜、面巾纸等
装置制作:
取矿泉水瓶盖,在瓶盖上钻一个孔,使一支香烟能够正好卡住,将矿泉水瓶去底,在上面蒙一层橡皮膜用胶水粘牢,松紧要适度,沿瓶盖内部边缘粘一层面巾纸,盖上瓶盖,这样一个简易的实验装置就制作完成了。
实验操作过程:
将一支香烟点燃,插在瓶盖事先打好的孔上,点燃部分向上,模拟人口吸烟过程,来回拉动矿泉水底部的橡皮膜,模拟人的呼吸,这时会发现有烟进入瓶中,而渐渐的会使面巾纸变成黄色,产生很多烟油附在纸巾上(面巾纸模拟人体肺部肺泡),而如果长时间拉动橡皮膜的话瓶子内就会形成一层尘垢。(瓶子模拟人体肺部)。
实验总结:
本实验通过运用材料,模拟了人体吸烟对人体危害的.过程,橡皮膜的拉动,模拟人不断呼吸、面巾纸模拟人体肺部肺泡、瓶子模拟人体肺部,通过一系列实验最终验证了吸烟有害健康。并且说明了吸烟对人体肺部的影响,从而告诫人们切勿吸烟本实验装置材料完全取材于生活,都是一些身边的物品,并且切实地说明了吸烟有害健康这一主题,制作简单,容易操作,实验效果明显使大家直观的了解实验结果,使大家明白吸烟几乎损害人体全部重要器官。对于这一点很多人不以为然,因为这需要时间证明,但我们绝不做此实验的试验品!能够使同学们通过自己动手做实验明白烟对人体的危害,从而达到使同学们远离香烟,拒绝吸烟,永于向香烟说“不!”还可以激发同学们的学习兴趣,促使同学们不断创新,不断努力,向着科学的世界冲!冲!冲!为了我们自己的健康,我们呼吁,全体同学都要自觉地远离香烟,并劝说吸烟的亲友尽量戒烟。毕竟,香烟对我们有害无益;毕竟,没有烟雾的空气会更加清新,没有烟草的生命会更加绚烂!同学们,让我们行动起来,从现在做起,从自我做起,严格控烟,向更多的人宣传吸烟有害健康的公益知识,呼吁全社会都珍惜自己和他人的生命,自觉控烟,坚决拒绝“二手烟”。使我们的天空更加湛蓝!使我们的明天更加辉煌!
这天,喜鹊宝宝早早就起来喊肚子饿:“妈妈、妈妈,快给我找吃的`、快给我找吃的!”喜鹊妈妈赶紧飞出去找。
过了一会儿,喜鹊宝宝急切地说:“妈妈怎么还没回来,我都快饿坏了!”
正在这时候,妈妈回来了,喜鹊妈妈降落到鸟窝上。喜鹊宝宝张开小嘴巴,说:“这是什么新玩意,头回冒烟的?快给我吃!”
喜鹊妈妈嘴里叼着一根烟,说:“先别着急,你猜猜这是什么东西?”
喜鹊宝宝眼睛眨了眨,说:“这是“冒烟虫”!”
喜鹊妈妈半信半疑地说:“应该是吧。刚刚麻鹰对我说这是危险物品,叫——烟。吃了会死的,可是我不相信,因为人类也照样吃,但会不会死我就不知道了。”
喜鹊宝宝根本就没听,只看着那条东西,眼睛也不眨一下,说:“不管什么三七二十一了,有得吃就行了!”
喜鹊妈妈说:“那倒是,吃吧!”说完,喜鹊妈妈就把香烟放在喜鹊宝宝的嘴里。
喜鹊宝宝吞下去以后,“咳咳,咳”地咳了起来。忽然,声音停了。
喜鹊妈妈看了看,宝宝死了,喜鹊妈妈后悔没有听麻鹰的劝告,依依不舍地流下了眼泪。
I attended Jack's birthday party tonight. After dinner, Jack gave cigarets to our boy students present.
At the important moment, I stop them and told them the bad effects of smoking: firstly Smoking is a waste of money and it's greatly harmful to our health. And it can lead to fires easily. So we should not smoke at all.
But it seemed helpless and they wouldn't listen to me. Somebody even said that body and health belonged to themselves and it's up to them to decide whether to smoke or not. I told him calmly, "Even if you have the right to harm your own body, but it doesn't mean that you have the same right to harm others'."
At last, they agreed with me, and some students said that they would never smoke any longer.
For the next one hour, we danced and sang happily, and nobody did smoke again.I felt very happy that my classmate all understood the harmness of smoking.
我今晚参加了杰克的生日派对。晚饭后,杰克给我们的男同学吸烟。
在重要的时刻,我阻止并告诉他们吸烟的不良影响:首先,吸烟很浪费钱,它对对我们的健康危害很大。它会很容易引起火灾。所以我们不应该吸烟,所以我们不能吸烟。
但很无奈似乎他们不听我的。甚至有人说身体是自己的,这是是否吸烟由他们自己说了算。我平静地说,“即使你有伤害自己身体的权利,但这并不意味着你要伤害别人的权利。”
最后,他们同意我的看法,一些学生说他们不会再抽烟了。
在接下来的一个小时里,我们跳舞,唱歌,没有人吸烟了。我感到非常高兴,我的同学都知道了吸烟的危害。
Smoking is a bad habit that does harm to smoker and others. Many kinds of diseases and cancers are caused by smoking, such as tracheitis, lung cancer and many other diseases. Recent years, there are tens of thousands of people dying of smoking. But there still are many people enjoying smoking, because they think smoking is a kind of fashion and smoking is so cool, especially among teenagers. In addition, smoking does harm to others as well. Second hand smoking has been recognized harmful to other people. Even worse, it may cause more damages. Therefore, people should remember that smoking is harmful to others and those people who smokes should give up smoking as soon as possible.
吸烟是个坏习惯,它对吸烟者和别人都有害。很多疾病和癌症是有吸烟引起的,比如说气管炎,肺癌还有很多其他疾病。近年来,成千上万的人死于吸烟。但是仍然有很多人喜欢吸烟,因为他们认为吸烟是一种时尚,很酷,特别是青少年。另外,吸烟也会对别人有害。二手烟是公认的对别人有害的。更糟糕的是,它会带来更多伤害。因此,人们应该牢记吸烟有害他人,那些吸烟的人应该尽可能戒烟。
