Natural and Artificial Materials

The video introduces the concept of materials, distinguishing between natural and artificial types. Natural materials are derived from animal, plant, or mineral sources, such as wool from sheep, wood from trees, and iron from rocks. Artificial materials are created by altering natural materials, like paper from wood and plastic from petroleum. The video emphasizes the environmental impact of plastic, which takes a long time to decompose, and encourages reducing its use. The video concludes with a call to explore more educational content.
