Objectives: Students will be able to explain the conservation of mass and demonstrate the process of balancing a chemical equation.

Standards:

HS.PS1.7- Use mathematical representations to support the claim, that atoms, and therefore mass, are conserved during a chemical reaction.

HS.Crosscutting.Energy- The total amount of energy in a closed system is conserved in a chemical reaction.
