  1. The material "wet clay" changes by drying. What caused the change?

    • shaking only
    • heating
    • changing its name
    • measuring its color

  2. What is the result when the material "ice cube" changes by melting?

    • solid wax
    • liquid water

  3. Which process describes the change to wet clay?

    • counting
    • coloring
    • weighing
    • drying

  4. How could a student try to reverse this change: water in a tray becomes solid ice?

    • warm the ice until it melts
    • draw a larger picture
    • count the table legs
    • rename the material

  5. Which order best shows the heating or cooling change for warm wax?

    • warm wax -> cooling -> solid wax
    • solid wax -> cooling -> warm wax
    • warm wax -> counting -> solid wax
    • cooling -> warm wax -> no change

    • coloring
    • weighing
    • melting
    • counting

  9. How could a student try to reverse this change: wet clay becomes hard dry clay?

    • hide the evidence
    • count the table legs
    • rename the material
    • add water and reshape before it fully dries

  10. Which order best shows the heating or cooling change for butter?
