This Grade 2 Science worksheet asks students to predict what state a material becomes when it is heated or cooled by the sun, a stove, or a freezer. Multiple-choice questions cover melting chocolate, boiling soup, and freezing juice, and fill-ins reinforce the before-and-after state words. A strong Grade 2 finish that lets learners use reasoning, not just memory, to describe the three states of matter clearly.
Style:
States of Matter
Part A: Multiple Choice
Circle the best answer for each question.
1. A chocolate bar is left in a hot car. What will it become?
A) A harder solid
B) A melted liquid
C) An invisible gas
D) A block of ice
2. A pot of soup boils on the stove. Some of the liquid becomes what?
A) Solid chunks
B) Heavier liquid
C) Steam, a gas
D) Ice
3. Juice is put in the freezer for a long time. What will it become?

A) Into the ground only
B) Into the air as gas
C) It disappears from matter
D) It turns to rock
Part B: Fill in the Blank
Write the correct answer on each line.
1. Heating a solid enough makes it melt into a liquid.
2. Cooling a liquid enough makes it freeze into a solid.
3. Boiling a liquid enough turns it into a gas.
4. If you cool steam down, it turns back into a liquid.
5. Adding or taking away heat can change the state of matter.
