An ice cube is left in a warm room. What happens to it?
- it turns into water vapor at once
- it melts into liquid water
- it gets colder and harder
2.
Water in a tray is put in a freezer. What does it become?
- water vapor
- warm water
- solid ice
3.
A puddle is gone after a sunny afternoon. Where did the water go?

About this worksheet

Changes in matter explain how heating and cooling change water in weather, and why some changes can be undone while others cannot helps third graders connect observations with scientific explanations instead of memorizing isolated facts. Students may think drops on a cold glass leak through it, or that every change can be reversed. This worksheet uses short evidence-based situations so students must read the setup, identify the pattern, and choose the answer that fits the science idea named in the title. Students name melting, freezing, evaporation and condensation, predict changes from temperature data, and tell changes that can be undone from changes such as burning and rusting.

Support versions use familiar examples and direct wording. Standard and challenge versions add closer distractors and require more comparison. Encourage your child to point to the evidence in the prompt before choosing an answer. If the answer does not explain the observation or solve the stated problem, it is probably a distractor. That habit builds careful science reasoning and prepares students for longer investigations.

What your child will learn

Name changes of state
Predict changes from temperature
Explain weather changes such as dew and icy roads
Tell changes that can be undone from those that cannot

NGSS standard: 5-PS1-4, 2-PS1-4

Worked example

At 25°F a puddle freezes; at 45°F the ice melts again, so freezing can be undone. A log burned to ash cannot become a log again.

Common mistake

Naming the material but ignoring whether it gained or lost heat.

Helpful hint

Ask whether the material got warmer or colder, and whether it can go back.

Questions parents ask

What is the most common mistake with changes in matter?

Naming the material but ignoring whether it gained or lost heat.

How can I help my child with changes in matter?

Ask whether the material got warmer or colder, and whether it can go back.
