In physics classes and general education classes, teaching the concept of fluorescence can be challenging, and it may seem too theoretical for some students. A short YouTube video titled ‘Seeing Photosynthesis from Space’ displays a global map of photosynthesis, and this is an excellent, attention-getting way to visually introduce fluorescence to students and also to address climate change. Therefore, three hands-on activities were designed using spinach chlorophyll ethanol extract and olive oil to observe the fluorescence emission; in addition, a smartphone spectrophotometer was employed to observe the spectrum of the emission. The class also addressed the issue of global warming because the absorption of CO₂ by plants and algae is decreasing, which may cause serious climate change.

在物理课上教授植物和藻类的荧光以应对气候变化

在物理课和普通教育课上，教授荧光的概念可能具有挑战性，并且对于某些学生来说似乎过于理论化。 YouTube 上一段名为“从太空观察光合作用”的简短视频展示了全球光合作用地图，这是一种极好的、引人注目的方式，可以向学生直观地介绍荧光并解决气候变化问题。因此，设计了三个动手活动，利用菠菜叶绿素乙醇提取物和橄榄油来观察荧光发射；此外，还使用智能手机分光光度计来观察发射光谱。该课程还讨论了全球变暖的问题，因为植物和藻类对CO ₂的吸收正在减少，这可能会导致严重的气候变化。
