Physical Changes
Grade 5 · Science · Properties of Matter · Nunavut, Canada
Lesson Summary
Recognize changes in matter where the substance itself stays the same.
Explanation
A physical change alters the appearance or form of matter but does not create a new substance. Cutting paper, melting ice, and dissolving sugar are all physical changes because the material is still the same thing, just in a different form. You can often reverse a physical change. For example, water can freeze into ice and then melt back into water.
