Exploring Changes in Matter

3rd Grade•30 minutes

Learning Objective

I can describe how matter can change from one form to another.

A physical change occurs when matter changes size, shape, or state but remains the same substance.

Examples of physical changes include cutting, bending, melting, freezing, and evaporating.

Mixing substances is a physical change if they don't form something new, and physical changes can often be reversed.

This lesson includes 3 practice questions to reinforce learning.
