Teacher Notes:
Related Standards:
- NGSS MS-PS1-2: Analyze and interpret data on the properties of substances before and after interaction to determine if a chemical reaction occurred.
- NGSS MS-PS1-5: 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.
