实验目的人所共知,吸烟危害身体健康。但究竟如何危害身体健康呢?教材中只有一个图示说明吸烟过程中产生的有害成分,资料说明中有一肺癌患者的肺与正常人肺的对比图。可这些对吸烟危害的解读比较抽象,不直观。于是我设计了一个真实、直观、形象的验证吸烟危害的实验。实验用品烟卷2支、蒸馏水、鲜鸡血、脱脂棉、无色酚酞试液。注射器一只(50mL)、过滤嘴(玻璃棉)、两只球形玻璃管、连接用乳胶管。
The purpose of the experiment is well known, smoking hazards to health. But exactly how to endanger the health of it? Only one teaching material shows the harmful components of the smoking process, the data shows a lung cancer patients lung and normal lung contrast chart. These interpretations of the dangers of smoking are more abstract, not intuitive. So I designed a real, intuitive, image of the experiment to verify the dangers of smoking. Experimental supplies cigarettes 2, distilled water, fresh chicken blood, absorbent cotton, colorless phenolphthalein test solution. A syringe (50mL), filter (glass wool), two spherical glass tube, connecting latex tube.
