Activities
- Define physical change.
- Define chemical change.
- Which phase change does a melting ice cube represent? Is it considered a physical or chemical phase change, and why?
- Is iron rusting considered a chemical or a physical change? Explain your reasoning.
- The formation of gas bubbles is often considered a chemical change, with the exception of water. Why is boiling water not considered a chemical change?
- Make a chart to classify each of the following as a physical change or a chemical change:
Answer Key/Rubric
- Physical changes are changes affecting the form of a substance, with no changes to its chemical structure. Physical changes can be reversed.
- Chemical changes happen when chemical bonds are broken or created, and a new substance is created. Chemical changes are generally irreversible.
- Melting occurs when a solid becomes a liquid. A melting ice cube is considered a physical change because it’s simply changing phase and the chemical makeup of the substance is not changing.
- Rusting is considered a chemical change because when a substance such as iron reacts with oxygen in the air or water, forming a new compound with a different chemical structure called iron oxide.
- When water boils, it turns from a liquid to a gas. When water boils, it still has the structure of two hydrogen atoms and one oxygen atom. Many other gas bubble formations decompose the substance’s structure.
