This Grade 5 physical changes worksheet helps fifth graders identify everyday physical changes such as crushing, melting, freezing, evaporating, and mixing. Students correct sentences, fill in vocabulary like substance and evaporates, and write short answers explaining why mixing sand or freezing juice keeps the same substance. The activities reinforce that physical changes alter form, shape, or state without creating new substances, supporting NGSS 5-PS1 standards.

Chemical and Physical Changes
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
Crushing a can into a flat shape are a chemical change.
Rewrite: Crushing a can into a flat shape is a physical change.
2. Fix the sentence:
When water freezes into ice, it becomes a brand new substance.
Rewrite: When water freezes into ice, it stays the same substance in a new state.
3. Fix the sentence:
Mixing sugar into water make a chemical change happen.
Rewrite: Mixing sugar into water makes a physical change happen.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. Melting butter on a pan is a physical change because the butter is still butter, only softer.
2. Tearing paper into strips changes its shape but not its substance, which stays the same.
3. When a puddle dries up after the rain, the water evaporates into vapor without changing identity.
4. Crushing chalk into powder is a physical change since the powder is still chalk.
Part C: Short Answer
Answer each question in one or two complete sentences.
1. Explain why mixing sand and gravel together is a physical change, not a chemical change.
Mixing sand and gravel is a physical change because no new substance forms. The sand is still sand, and the gravel is still gravel. You can sift them apart and get back exactly what you started with, which proves their chemical identities never changed.
2. Describe how freezing juice into a popsicle is a physical change at the molecular level.
Freezing juice into a popsicle is a physical change because the juice molecules slow down and lock into a solid pattern, but they are still juice molecules. No new substances form. If the popsicle melts, you get the same juice back, showing the change is only in state, not identity.
