What your child learns

  • Conservation of atoms in a reaction
  • Coefficients and formulas
  • Finding the smallest whole numbers that balance

How to play

Use plus and minus under each molecule until every element matches on both sides, then check. Balanced with the smallest numbers is right. Four reactions finish a level.

Levels

  1. Level 1Simple reactions like water and salt.
  2. Level 2More molecules.
  3. Level 3Burning fuels and harder reactions.

A tip for parents

Ask your teen to explain why the number of atoms can’t change in a reaction.
