    • a magnet pulls out the iron filings
    • the parts can still be seen and picked out

  3. Which method could separate salt water?

    • evaporate the water and collect the salt
    • evaporate water to leave dissolved solids
    • pour or skim off the oil layer
    • filter the water through paper

  4. The graph shows mass before and after making oil and water. What does it support?

    • the matter disappears after mixing
    • a solution has no mass
    • the total mass stays the same when no material is lost
    • all mixtures become pure water
