Investigation 1. Separating Mixtures. Part 1 – Making & Separating Mixtures. Vocabulary. Mixture. – a substance containing two or more materials with different properties.. Property. – a characteristic of an object (something you can observe). Chapter 9.3 Part 1. Q: What is the dullest element? A: . Bohrium. . Key concepts:. Describe 3 properties of mixtures. Describe 4 methods of separating mixtures. Give everyday examples of mixtures. Key Vocabulary:. what is . homegeneous. ?. What is solute ?. Uniformly mixed – only see one layer. substance that dissolve in a solvent. What is solvent?. Is a substance that dissolves the solute. What is solution ?. SEPARATING MIXTURES. Discuss with a partner how you would separate the following mixtures… . Salt . water . Muddy . water . Iron . filings and sand . Vegetable . oil and sand . Vegetable . oil and water . Mixtures and Solutions. Investigation 1. Part 1. Making and Separating Mixtures. What is a mixture?. What is a solution?. What is the difference b/t a mixture and solution?. Our first investigation is figuring out what a mixture is and what a solution is…. Mixtures may be separated by many different techniques based on differing physical and/or chemical properties. Sorting. Simply picking apart the different components. This can be easy and obvious…. Grade 9 Science. Mixtures can be separated by physical means…. Filtration can be used to separate an insoluble substance from a soluble substance. Evaporation can be used to separate a solute from the solvent in a solution. Types of Separation. Mechanical Means of Separation. Density Separation. Centrifugation. Non-Mechanical Means of Separation. Chromatography. Distillation. Froth Flotation. 2.3 Separating the Substances in a Mixture. Introduction. matter. : anything having mass and volume. . mass. :. . weight. :. . volume. :. . units: . L, dm. 3. , mL, cm. 3. . state of matter. :. . the amount of matter in an object. . the pull of gravity on an object. Divisions of Matter. Pure Substance. Cannot be broken down and retain its properties.. Has a fixed composition.. Every sample of a pure substance has EXACTLY the same composition AND exactly the same characteristics - homogeneous. Chapter 5. Ex:. Melting. Freezing. Boiling/evaporation. Condensation. Sublimation. Dissolving. Bending. Crushing. Breaking. Chopping. Filtration. distillation. Physical change. Does not make a different substance. Problem. Given two sets of points, . R. and . B. . ∈. . R. ² where |. R. | = . n. and |. B. | = . m. :. Find the smallest circle containing all of . R. and as few points as possible from . B. Mixtures Many of the substances we use everyday were actually once part of a mixture Someone somewhere separated that substance from the mixture so we could use it Separating substances from mixtures Keywords. :. DATE. Learning Objectives. Recognise the difference between materials, substances and . elements . Identify . elements by their names and . symbols. Explain . what is meant by a chemically pure substance.
