Synopsis
- This short video from the Paleontological Research Institution describes how different forms of radiant energy interact with different materials and demonstrates an easy experiment that could be replicated in the classroom.
- The demonstration involves viewing one's hand with an infrared camera behind three different types of materials: glass, clear plastic, and black plastic.
Subjects: Physics

Teaching Materials
Positives
- A thorough verbal explanation and visual demonstration show how certain materials like glass can absorb infrared radiation, similar to how greenhouse gases also trap infrared radiation.
- The narrator describes all components of the demonstration, easily allowing a teacher to replicate this same setup in their classroom if they have access to the infrared camera technology.
Prerequisites
- Students should be familiar with terms like visible light, infrared radiation, and wavelength.
- To replicate this in the classroom, you will need an infrared camera, glass, clear plastic, and black plastic.
Differentiation & Implementation
- Before watching the video, consider having students record their predictions on the absorption or transmission of infrared radiation and visible light for each of the three materials tested in the video.
- To dive deeper into the science of the greenhouse effect and climate change, high school students may benefit from this interactive online lesson: Heating It Up: The Chemistry of the Greenhouse Effect.
- Teachers can use this video to introduce the greenhouse effect and greenhouse gases, which can then be used to teach about climate change.
