Physical vs Chemical Change: Visual Science Explanation for Students #3069237 (License: Personal Use)

On the left, a hand uses an axe to split logs, illustrating a physical change where the wood’s form changes but its molecular composition stays the same. On the right, logs burn intensely, producing flames and blackened ashes-a classic chemical change where combustion transforms wood into new substances like carbon dioxide, water vapor, and ash.

This image is commonly used in K-12 science curricula, educational websites, and teacher lesson plans to visually differentiate physical and chemical changes; it serves users seeking foundational chemistry concepts or classroom-ready visuals.
