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！

冰淇淋是生活中不可缺少的一道美食。夏天没胃口时，尝些冰淇淋，是一个迅速补充体力降低体温的好方法。尤其对小朋友来说更是挡不住的诱惑，聪明的妈妈能在小朋友不愿吃饭时，偶尔改变方式以冰淇淋取代主食，同样能摄取营养和热量，漂亮的颜色又让人产生食欲。
你知道吗？美国每年能销售10亿加仑的冰淇淋，8%的牛奶最终变成冷冻食品。如今，各种各样的冰淇淋店更是遍布世界。现在就让我们一起看看冰淇淋的历史吧。
The earliest reports of people enjoying flavored ice desserts come from the Romans and the Chinese. Marco Polo returned from his famous expedition with fruit-flavored ices, reporting that Asians had been making them for thousands of years. These delicacies became popular in France in the 1500s, but only among royalty. Over the next few centuries, the process of making them evolved from hauling mountain ice to salt/ice freezing methods. Cream was introduced as an ingredient, and by the 1700s, people were enjoying a dessert that was very similar to today's ice cream.
The hand-cranked ice cream freezer was first developed by Nancy Johnson in 1846. Ice was readily available from large warehouses in that era, so ice cream became a treat that could be enjoyed by almost anyone, not just the rich. Ice cream making was revolutionized again in 1851, when Jacob Fussel started the first wholesale ice cream manufacturing operation in Baltimore, Maryland. Fussel's dairy business had excess cream and he couldn't figure out what to do with it. He tried using it to make ice cream, and before long his ice cream business outsold the rest of the dairy.
The business slowly evolved for the next few decades. Manufacturing methods and ingredients improved, while refrigeration technology became cheaper and more efficient. By the 1920s, home refrigerators and freezers became more common, which gave the ice cream industry another boost. Sugar was rationed in the US during World War I, but the ice cream industry convinced the government that ice cream was an "essential food”. Ice cream factories were allotted sugar rations and production continued.
Ice cream increased in popularity until the Depression years caused a drop in sales for virtually all non-essential goods. Sales increased in the years leading up to World War II before leveling off in the post-war years. The rise of the giant supermarket created demand for cheaper, mass-produced ice cream, but quality suffered. The 1960s saw a resurgence in "premium"ice cream, while the following decades saw the market fragment into low-fat varieties for the health-conscious, including frozen yogurt, fruit bars, ice milk, fat-free ice cream, and dozens of other varieties. However, ice cream still makes up about 60 percent of the market share among frozen desserts. While ice cream is enjoyed worldwide, it has become an American tradition

走进那个大大的棚子，各种香味扑面而来。我迫不及待地走进一个又一个的摊子品尝起来。这时，一个奇特的牌子吸引了我的`注意力。上面写着——“马桶”冰淇淋。我走过去瞧了瞧，天哪，装冰淇淋的容器竟是各种颜色的马桶造型！我立刻买了一份。
我端着一个马桶……哦不，应该是冰淇淋，边走边观察着，三种颜色的冰淇淋球放在“马桶”容器里，看上去十分诱人。有草莓味，有香草味，剩下一种是巧克力味。我实在忍不住了，顾不上造型的奇葩，一勺又一勺地吃了起来。
才一会功夫，我和妈妈就你一口我一口地把冰淇淋球吃完了，“马桶”里只剩下巧克力味的冰淇淋球了。由于天气太热，此时冰淇淋已经开始融化了，这样看起来，这个“马桶”容器就体现出它的特别了。巧克力色的冰淇淋慢慢在“马桶”里化成了水……我实在是吃不下去，就推给了妈妈。看着妈妈一点一点地吃完了冰淇淋，我再也忍不住了，哈哈大笑起来。
现在，那个“马桶”被我洗干净放在架子上。每每看到它，我都会想起那令人难忘的“马桶”冰淇淋，不禁嘴角上扬，开心的笑了起来。
