  1. The material "water in a tray" changes by freezing. What caused the change?

    • putting it on paper
    • changing its name
    • cooling

  2. What is the result when the material "warm wax" changes by hardening?

    • liquid butter
    • solid ice
    • solid wax

  3. Which process describes the change to water in a tray?

    • weighing
    • freezing
    • counting

  4. How could a student try to reverse this change: ice cube becomes liquid water?

    • cool the water until it freezes
    • hide the evidence
    • rename the material

  5. Which order best shows the heating or cooling change for water in a tray?

    • water in a tray -> cooling -> solid ice
    • solid ice -> cooling -> water in a tray
    • water in a tray -> counting -> solid ice

  6. The material "chocolate piece" changes by melting. What caused the change?

    • putting it on paper
    • changing its name
    • heating

  7. What is the result when the material "water in a tray" changes by freezing?

    • solid wax
    • solid ice
    • hard dry clay

  8. Which process describes the change to warm wax?

    • weighing
    • sorting
    • hardening

  9. How could a student try to reverse this change: warm wax becomes solid wax?

    • hide the evidence
    • heat the wax until it softens
    • draw a larger picture

  10. Which order best shows the heating or cooling change for water in a tray?

    • water in a tray -> cooling -> solid ice
    • solid ice -> sorting -> cooling
    • water in a tray -> counting -> solid ice
