Standard: 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.
Students explore the complicated task of balancing equations through a hands-on modeling activity. The standard only requires students to model the balanced equation; however, students are able to balance equations without a model after this assignment!
