What Is a Balancing Equations Race?
A balancing equations race is a competitive activity where students or teams race against each other to correctly balance a set of chemical equations within a limited time. The goal is to correctly balance as many equations as possible before the timer runs out, earning points for each correct answer. This activity not only reinforces students’ understanding of conservation of mass but also encourages strategic thinking and quick problem-solving skills.
