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）。
