MS-PS1-5: Conservation of Atoms in Reactions
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. (Energy and Matter)
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.

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
6.RP.A.3 - Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations.
MP.2 - Reason abstractly and quantitatively.
MP.4 - Model with mathematics.
