Three concepts necessary for understanding the greenhouse effect are infrared radiation, absorption of infrared radiation by greenhouse gases, and steady-state energy flow. Herein, we describe adaptations to three classic demonstrations for teaching these concepts. William Hershel’s discovery of infrared radiation has been adapted into a fast and reliable demonstration using a pyranometer. We provide guidelines for building a ball-and-spring model of carbon dioxide that demonstrates the absorption of IR and the three fundamental vibrational modes of carbon dioxide and their relative frequencies. Finally, we describe an adaptation of Blanck’s plastic water-flow device to demonstrate how adding greenhouse gases can alter the steady-state flow of energy through the atmosphere.

改编三个经典的示范以教授与温室效应有关的辐射能捕获和转移

了解温室效应的三个必要概念是红外辐射，温室气体吸收红外辐射和稳态能流。在这里，我们描述了对三个经典演示的改编，以教授这些概念。威廉·赫歇尔（William Hershel）对红外辐射的发现已被应用到总辐射表中，以进行快速，可靠的演示。我们提供了建立二氧化碳的球弹簧模型的指南，该模型演示了IR的吸收以及二氧化碳的三种基本振动模式及其相对频率。最后，我们描述了Blanck塑料水流装置的一种改型，以演示添加温室气体如何改变通过大气的稳态能量流。
