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

    • wet sand mixture
    • gas spreads into the room
    • solid ice
    • liquid water drops

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

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

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

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

  4. If balloon air changes and the result is "gas spreads into the room", 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 "mixing with water" is scientific?

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

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

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

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

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

  8. Which evidence would show matter changed after sand went through mixing with water?

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

  9. If water in a cup changes and the result is "solid ice", what should a scientist compare?

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

  10. Which statement about "freezing" is scientific?

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