Description

A video of magnesium ribbon being dropped into a solution of hydrochloric acid is the investigative phenomenon. Students use manipulatives to model how to balance chemical equations and understand the law of conservation of mass. These tools help students visualize the number of atoms participating in each side of a chemical reaction by modeling the reactants and products. They make sense of the phenomenon and discover the answer to the driving question, “How do you write a chemical equation so that the number and type of atoms on the reactant and product sides are balanced?”
