PRODUCT DESCRIPTION

The purpose of this activity is to provide a visual for students so that they can balance 5 chemical equations while obeying the Law of Conservation of Mass. Students will build species on either side of the chemical equation in order to balance the elements on both side of the chemical equation. In addition students will classify the 5 chemical equations once they have balanced the chemical equations. The 5 classes of reactions in this activity are combustion, single displacement (aka single replacement), synthesis, double displacement (aka double replacement), and decomposition. Students may draw and color the needed species, for a more economical activity, or the teacher can purchase ¾” and ¼” self-adhesive dots, for an activity that looks neater and takes less time. Depending on the species students will also learn the difference between a covalently-bonded species (use black lines for the bonds) and a substance held together with ionic bonds (the sticky dots touch each other).
