Next Generation Science Standards: HS-PS1-7
-- Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.
-- Disciplinary Core Ideas: PS1.B Chemical Reactions
-- The total number of each type of atom is conserved, and thus the mass does not change.
-- The fact that atoms are conserved, together with knowledge of the chemical properties of the elements
involved, can be used to describe and predict chemical reactions.
-- Crosscutting Concepts: Energy and Matter
-- The total amount of energy and matter in closed systems is conserved.
-- Science and Engineering: Using Mathematics and Computational Thinking
-- Use mathematical representations of phenomena to support claims.
-- MP.2 Reason abstractly and quantitatively
-- HSN-Q.A.1 Use units as a way to understand problems and to guide the solution of multi-step problems;
choose and interpret units consistently in formulas; choose and interpret the scale and the origin in graphs and
-- HSN-Q.A.2 Define appropriate quantities for the purpose of descriptive modeling.
