  1. What result is described when juice changes by freezing?

    • liquid water drops
    • liquid water
    • gas spreads into the room
    • solid juice pop

  2. Which process could change the material into "liquid water drops"?

    • mixing with water
    • melting
    • cooling
    • letting it out

  3. Which evidence would show matter changed after water in a cup went through freezing?

    • the material was observed before only
    • the same property stayed unchanged
    • the result was not recorded
    • the material has different observable properties

  4. If ice cube changes and the result is "liquid water", what should a scientist compare?

    • only the starting material
    • only the process name
    • only the container size
    • properties before and after the change

  5. Which statement about "melting" is scientific?

    • the result matters without any process
    • only the material name should be compared
    • melting can change observable properties of matter
    • properties cannot change during a test

  6. What result is described when water in a cup changes by freezing?

    • solid ice
    • wet sand mixture
    • liquid water drops
    • liquid water

  7. Which process could change the material into "solid juice pop"?

    • letting it out
    • freezing
    • mixing with water
    • melting
