This resource is a lab simulation in which students explore the law of conservation of mass during chemical reactions. Students begin by using sandwich pieces to model the reactants and products in a reaction. They then use molecules. The simulation includes a game in which students identify the number of molecules on one side of a reaction. This resource includes student and teacher handouts as well as an optional pre-lab. The accompanying simulation can be found here: https://phet.colorado.edu/en/simulation/reactants-products-and-leftovers
