Grades 912. Introduce and reinforce balancing chemical equations with this model-based kit. Students use colorful manipulatives and a unique balancing equations mat to understand the law of conservation of mass and to visualize the number of atoms participating in each side of a chemical reaction. This activity also helps students understand the difference between coefficients and subscripts in chemical equations. Balancing Chemical Equations Kit (item #840656) contains enough materials for 10 groups, pairs, or students working individually. The Balancing Chemical Equations Expansion Pack (item #840675) extends the number and variety of equations students can balance using the kit, enabling them to gain practice with more-challenging reactions. Kit and Expansion Pack combined provide fully reusable materials for 10 groups, pairs, or individual students.
