Part B: Fill in the Blank (4 questions)
6. Ice is the _______ state of water.
7. When water boils, it becomes _______.
8. The three main states of matter are solid, _______, and gas.
9. Matter that flows and takes the shape of its container is a _______.

✅ ANSWER KEY - AT GRADE LEVEL
1. c) Solid - Solids have a definite shape and volume because particles are tightly packed
2. b) They speed up - Heat energy makes particles move faster
3. b) 0°C - This is the freezing point of water
4. c) Air - Air is a mixture of gases at room temperature
5. b) solid to liquid - This phase change is called melting
6. solid - Ice is frozen water in solid state
7. steam/gas - Water vapor forms when water boils
8. liquid - The three states are solid, liquid, and gas
9. liquid - Liquids flow and take the shape of their container

📝 EXAMPLES - AT GRADE LEVEL
Example: "Think about an ice cube. It has its own shape (square) and takes up space. This makes it a solid. When it melts, it becomes water that flows - a liquid."

Part B: Fill in the Blank (4 questions)
6. Ice is _______ water.
7. When water gets very hot, it becomes _______.
8. Water and juice are both _______.
9. Rocks and ice cubes are both _______.

✅ ANSWER KEY - BELOW GRADE LEVEL
1. b) It keeps its shape - Solids don't change their shape
2. b) Pour and flow - Liquids can move and pour
3. b) Everywhere around us - We breathe air (gas) all the time
4. b) It freezes into ice - Cold makes water turn solid
5. a) Steam is hot, ice is cold - They are different temperatures
6. solid - Ice is frozen, solid water
7. steam - Hot water becomes steam (gas)
8. liquid - Both water and juice flow and pour
9. solid - Both keep their shape and are hard

📝 EXAMPLES - BELOW GRADE LEVEL
Example: "Look at ice in your freezer. It stays the same shape until it melts. When you pour juice, it changes shape to fit the cup."
