Title: MS-PS1 Matter and Its Interactions
Performance Expectation: Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved. [Clarification Statement: Emphasis is on law of conservation of matter and on physical models or drawings, including digital forms, that represent atoms.] [Assessment Boundary: Assessment does not include the use of atomic masses, balancing symbolic equations, or intermolecular forces.]
Disciplinary Core Idea(s):
PS1.B: Chemical Reactions Substances react chemically in characteristic ways. In a chemical process, the atoms that make up the original substances are regrouped into different molecules, and these new substances have different properties from those of the reactants. The total number of each type of atom is conserved, and thus the mass does not change.
Science & Engineering Practices: Developing and Using Models Develop a model to describe unobservable mechanisms. Connections to Nature of Science: Science Models, Laws, Mechanisms, and Theories Explain Natural Phenomena Laws are regularities or mathematical descriptions of natural phenomena.
Crosscutting Concepts: Energy and Matter Matter is conserved because atoms are conserved in physical and chemical processes.
California Environmental Principles and Concepts:
Principle II The long-term functioning and health of terrestrial, freshwater, coastal, and marine ecosystems are influenced by their relationships with human societies.
California Common Core State Standards Connections:
ELA/Literacy RST.6-8.7: Integrate quantitative or technical information expressed in words in a text with a version of that information expressed visually (e.g., in a flowchart, diagram, model, graph, or table). Mathematics MP.2: Reason abstractly and quantitatively. MP.4: Model with mathematics. 6.RP.3: Use ratio and rate reasoning to solve real-world and mathematical problems.
DCI Connections:
Connections to other DCIs in this grade-band: MS.LS1.C; MS.LS2.B; MS.ESS2.A Articulation across grade-bands: 5.PS1.B; HS.PS1.B
