Light Interactions with Materials in Everyday Life

The video tutorial introduces Grade 5 students to the concept of how light interacts with different materials. It covers topics such as refraction, reflection, absorption, and transmission of light. The lesson uses examples like rainbows, stained glass, and various objects to explain these concepts. Students learn about visible light and optics, and the video concludes with a flowchart summarizing the different ways light can interact with materials.
