SC069007	When a chemical reaction occurs, the characteristic properties of the products are different than the characteristic properties of the reactants. (This item used a table to show the properties of the substances.)

Items associated with this NGSS statement in this project (Original Project) and other key ideas
SC061004	Smelling two liquids can help a student determine if the liquids are the same substance.
SC063004	To identify a liquid, you could determine the boiling point of the liquid and compare it to the boiling points of other liquids.
SC095002	To help identify a metal, you could determine its melting point and compare it to the melting point of other metals.
SC095003	To help identify a metal, you could determine its density and compare it to the density of other metals.
SC099002	Determining the mass of a liquid and comparing its mass to the mass of other liquids will NOT help you identify the liquid.
SC046005	How much of a substance dissolves in water is a characteristic property of the substance.
SC057007	Two solids with the same melting point and color could be the same substance. (This item uses a table that lists properties of the solids.)
SC057008	Two solids with the same melting point and color could be the same substance. (This item uses a table that lists properties of the solids.)
SC064007	Two liquids with the same density and color but different boiling points are different substances. (This item uses a table that lists properties of the liquids.)
SC064008	Two liquids with the same density and color but different boiling points are different substances. (This item uses a table that lists properties of the liquids.)
SC100003	Two liquids with the same flammability, boiling point, and color could be the same substance. (This item uses a table that lists properties of the solids.)
SC100004	Two liquids with the same boiling point and color could be the same substance. (This item uses a table that lists properties of the liquids.)
SC044004	If a piece of wax is removed from a ball of wax, the mass of the ball of wax would change but its melting point would stay the same.
