Lesson: Conservation of Mass Chemistry • First Year of Secondary School

In this lesson, we will learn how to use the law of conservation of mass to calculate the masses of reactants and products in a chemical reaction.

Lesson Plan

Students will be able to

describe the law of conservation of mass as applied to chemical reactions,
use the law of conservation of mass to calculate the mass of reactants or products in a chemical reaction,
identify the relationship between conservation of mass and the balancing of chemical equations,
identify why the total mass of the products may appear to change when performing experiments in an open system.
