Content Area Standard Strand By the end of grade P 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 Content Statement CPI# Observations and investigations form a basis for young learners’ understanding of changes in matter. 5.2.P.B.1 2 Some properties of matter can change as a result of processes such as heating and cooling. Not all materials respond the same way to these processes. 5.2.2.B.1 4 Many substances can be changed from one state to another by heating or cooling. 5.2.4.B.1 Cumulative Progress Indicator (CPI) ACSSSD Objectives Explore changes in liquids and solids when substances are combined, heated, or cooled (e.g., mix sand or clay with various amounts of water; mix different colors of tempera paints; freeze and melt water and other liquids). Generate accurate data and organize arguments to show that not all substances respond the same way when heated or cooled, using common materials, such as shortening or candle wax. a. Attend to science objects, materials and activities. b. Demonstrate an awareness of an ongoing investigation, experiment or project. Predict and explain what happens when a common substance, such as shortening or candle wax, is heated to melting and then cooled to a solid. a. Make predictions about familiar events. b. Conduct an experiment to change an item’s matter state. c. Connecting matter states to various catalysts. a. Define states of matter by their properties. b. Identify ways to collect data. c. Identify ways to organize data. d. Conduct simple experiments and record data. 6 When a new substance is made by combining two or more substances, it has properties that are different from the original substances. 5.2.6.B.1 Compare the properties of reactants with the properties of the products when two or more substances are combined and react chemically. a. Identify the characteristics of a substance. b. List the characteristics of original and final substances. c. Define: reactant, property and substance. d. Identify possible chemical reactions. 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. a. Define mass, atom and product b. Recognize a chemical change. c. Demonstrate the ability to calculate the mass of a substance. 12 A large number of important reactions involve the transfer of either electrons or hydrogen ions between reacting ions, molecules, or atoms. In other chemical reactions, atoms interact with one another by sharing electrons to create a bond. 5.2.12.B.2 Describe oxidation and reduction reactions, and give examples of oxidation and reduction reactions that have an impact on the environment, such as corrosion and the burning of fuel. a. Define electron, ion and molecule. b. Define oxidation, reduction reaction and corrosion. c. Identify chemical reactions in the environment. d. Connect an environmental condition to the chemical reaction that caused it.
