Summary Light a ping pong ball on fire, and discuss the chemistry. Science content Chemistry: Chemical Changes (2, 7) Physics: Energy forms, Conservation of Energy (1, 3, 4, 5) Lessons activity is in Combustion Materials ping pong ball lighter heat proof tray outdoors Procedure Light the ping pong ball and watch it burn. The ping pong ball is fuel for a combustion reaction: it combines with oxygen to release heat and light. Carbon dioxide and water are made, along with an ash.
