PPT-Mixtures and Solutions

Investigation 1 Lets talk about our results Which mixtures were separated by the screen Gravel Which mixtures were separated by the filter Powder How are the screen and filter similar. 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). 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 ?. Mr. McMartin. Beta Science. Mixtures. Mixture: a combination of two or more substances that are not chemically combined.. Can only become a mixture if they do not react to form a compound.. There are no chemical changes that happen in a mixture.. Grade 7. Matter. is anything that has mass and takes up space. Mass is the amount of matter in an object. . A. Solid . is matter that has a definite shape and volume. A . liquid. is matter that does not have a definite shape, but has a definite volume. 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…. Mixtures. Solutions are a type of mixture, so to understand solutions, first we have to know what a mixture is…. A . mixture. is a combination of two or more substances. Each substance keeps it’s own properties, even though it is mixed with another substance. They . Separation of Matter Notes. Matter Flowchart. A. Separating Heterogeneous Mixtures. . Based on differences in the size or density of the pure substances making up the . mixture. Decanting. Filtering. Solutions and Other Mixtures. Objectives. Distinguish between heterogeneous mixtures and homogeneous mixtures.. Compare the properties of suspensions, colloids, and solutions.. Give examples of solutions that contain solids or gases.. Mixtures. A combination of two or more substances that do not combine chemically, but remain the same individual substances; can be separated by physical means. Two types:. Heterogeneous. 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. Grade 5 Quarter 1 Topic 4 . Mixtures . and Solutions. Mary . Tweedy, Curriculum Support . Specialist. . Keisha Kidd, . Curriculum Support Specialist. Dr. .
