2 KClO3(s) → 2 KCl(s) + 3 O2(g)
This provides sufficient oxygen to ignite and oxidize the sugar in the gummy bear, which is an exothermic reaction:
C12H22O11(s) + 3 O2(g) → 9 C(s) + 3 CO2(g) + H2O(g) ΔH = 5635 kJ

The following day we talked about boats. Since we live along a major river and a few miles from the ocean, I thought it might make the whole "metals rust" notion relevant with protecting marine props from salt water corrosion with zinc anodes. They started getting the idea of how the electrons move, but are still struggling with writing the equations.
