Mixture Separation Lab Remember – All steps with a STAR need to be written in your notebook! PURPOSE To separate a mixture into its pure substances using characteristic properties RESEARCH: Write out the definition of characteristic properties Also, write down the list that was brainstormed in class on how to separate mixtures. HYPOTHESIS – none required Materials 1. Filter paper 2. Plastic cups 3. Powedered Milk 4. Iron Filings 5. Sawdust 6.. Pieces of Ribbon 7. Unlimited supply of water 8. Paper towel 9. Bowl holding supplies 10. Paper clips 11. Magnet SAFETY RULES: - Iron filings may not get wet! - Magnets may not come out of bag! EXPERIMENT You’ll be figuring this out with your group. I’m not going to require you to write out the steps, but you will have to answer questions about it in your conclusion. Think about the CHARACTERISTIC PROPERTIES of your mixture items (sponge chunks, table salt, and sawdust to create your method). ANALYSIS OBSERVATIONS: Write 1-2 observations throughout your experiment. POSSIBLE ERRORS: Write 1-2 possible errors throughout your experiment. CONCLUSION Write a few sentences in a paragraph form that answers -What characteristic property of the ribbon did you use to separate them from the mixture? - What characteristic property of the saw dust did you use to separate them from the mixture? - What characteristic property of the powdered milk did you use to separate them from the mixture? - What characteristic property of the iron filings did you use to separate them from the mixture? -How successful were you at separating your mixture - What would you do different next time to improve this experiment?
