Science Updated August 1, 2010 Physical Sciences NM Strand, Standard, Benchmark – Performance Standard II, I, III-1 Understand that substances have characteristic properties and identify the properties of various substances (e.g., density, boiling point, solubility, chemical reactivity). Matter Sixth Grade Complex Simple The student will be able to: The student will know: the differences between chemical and physical properties can influence the interaction of matter there are about 100 known elements that combine to produce compounds in living organisms and nonliving substances use properties to identify hardness, streak, color, cleavage, fracture, and luster of substances (i.e. for minerals) and how these substances react to acid substances have characteristic properties that help identify them understand the difference between chemical and physical properties II, I, III-2 Use properties to identify substances (e.g., for minerals: the hardness, streak, color, reactivity to acid, cleavage, fracture). II, I, III-3 Know that there are about 100 known elements that combine to produce compounds in living organisms and nonliving substances. II, I, III-4 Know the differences between chemical and physical properties and how these properties can influence the interactions of matter. identify the properties of various substances (i.e. density, boiling point, solubility, chemical reactivity) The student will recognize and recall the following Six Step vocabulary words: hardness streak cleavage fracture luster
