  1. muddy water: soil particles are suspended in water. Is it a mixture or a solution?

    • pure substance
    • solution
    • mixture
    • new substance

  2. Which evidence supports calling trail mix a mixture?

    • filter paper catches the soil particles
    • two liquid layers can be seen
    • the parts can still be seen and picked out
    • a magnet pulls out the iron filings

  3. Which method could separate muddy water?

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

  4. The graph shows mass before and after making trail mix. What does it support?

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

  5. Which question belongs in a mixtures and solutions investigation about salt water?

    • Does the sample have a predator?
    • Can the parts be separated by their properties?
    • Which Moon phase is shown?
    • How many syllables are in the sample name?

  6. salt water: salt dissolves evenly in water. Is it a mixture or a solution?

    • pure substance
    • solution
    • mixture
    • new substance

  7. Which evidence supports calling salt water a solution?

    • two liquid layers can be seen
    • the liquid looks the same throughout
    • no salt grains are visible after stirring
    • a magnet pulls out the iron filings

  8. Which method could separate oil and water?

    • sort the pieces by hand
    • filter the water through paper
    • pour or skim off the oil layer
    • use a magnet to remove the iron

  9. The graph shows mass before and after making muddy water. What does it support?

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

  10. Which question belongs in a mixtures and solutions investigation about muddy water?

    • Can the parts be separated by their properties?
    • Does the sample have a predator?
    • Which Moon phase is shown?
    • How many syllables are in the sample name?
