4-2-b Distinguish between physical and chemical changes and between objects composed of a single substance from those composed of more than one substance. (DOK 2) Walk Through Paper***** John Hunt MAST 2012

5-2-b Differentiate between elements, compounds, and mixtures and between chemical and physical changes (e.g. gas evolves, color, and/or temperature changes). (DOK 2) Shrinking Mixture* Disappearing Liquid***** Chalk Chromatography***** Coffee Filters***** John Hunt MAST 2012

5-2-b Differentiate between elements, compounds, and mixtures and between chemical and physical changes (e.g. gas evolves, color, and/or temperature changes). (DOK 2) Continued John Hunt MAST 2012 Tie Dye Milk* Gail Steve Spangler Steve Spangler Marbling* Weather or Not Flower*****

6-2-b Distinguish physical properties of matter (e.g. melting points, boiling points, solubility) as it relates to changes in states. (DOK 2) Lifting an Ice Cube***** Gleup***** Solubility in water (solvent) of various solids (solutes) to activities (e.g. heating, stirring, shaking, crushing) on the rate of solution (solvent). Marbling* Use of solubility differences to identify components of a mixture (e.g. chromatography). DOK 2 M & M Pigment Separation***** T-Shirt Chromatograms (PROJECT) John Hunt MAST 2012
