Improve 11–14 year-old learners’ understanding of this fundamental chemistry topic

The law of conservation of mass has been around since the mid-18^th century, yet it’s still a sticky concept for students to grasp. Here, Kristy Turner lays down four foundation stones of teaching the fundamental chemistry topic to 11–14 year-old learners. Use the teaching ideas to improve student understanding of conservation of mass and help them with more advanced topics, such as balancing equations and stoichiometry calculations.
