Physical Change Explained: Folding a Paper Plane

Next Generation Science

This concise educational video utilizes a simple, relatable demonstration to explain the concept of physical change within the context of basic chemistry and physics. The video features a clear, step-by-step visual of a student folding a piece of paper into a paper airplane. This familiar activity serves as the anchor for a scientific inquiry question posed at the beginning: "Is folding a paper plane an example of physical or chemical change?" The core theme explores the properties of matter and how to distinguish between physical and chemical changes. Specifically, it highlights that while the *shape* and *form* of an object may be altered during a process, if the underlying substance remains the same and "no new matter is produced," it is classified as a physical change. The video provides a clear definition and criteria for identification that students can apply to other scenarios. For educators, this video is an excellent hook or reinforcing tool for a unit on Matter and Its Interactions. Its brevity makes it perfect for a "bell ringer" activity where students hypothesize the answer before the explanation is revealed. It effectively models scientific observation and provides a low-barrier-to-entry experiment that can be immediately replicated in the classroom with nothing more than a sheet of paper, allowing students to physically experience the concept being taught.
