3-20-2012 MIXING UP REACTIONS AND CHANGES - CCCS for Science

5.2 Physical Science: All students will understand that physical science principles, including fundamental ideas about matter, energy, and motion, are powerful conceptual tools for making sense of phenomena in physical, living, and Earth systems science.


B. Changes in Matter :  Substances can undergo physical or chemical changes to form new substances. Each change involves energy.

8	When substances undergo chemical change, the number and kinds of atoms in the reactants are the same as the number and kinds of atoms in the products. The mass of the reactants is the same as the mass of the products.	5.2.8.B.1	Explain, using an understanding of the concept of chemical change, why the mass of reactants and the mass of products remain constant.
8	Chemical changes can occur when two substances, elements, or compounds react and produce one or more different substances. The physical and chemical properties of the products are different from those of the reacting substances.	5.2.8.B.2	Compare and contrast the physical properties of reactants with products after a chemical reaction, such as those that occur during
