In session one, demonstrate for your class how a flame eventually goes out when enclosed in a jar in order to teach that oxygen is required for combustion. In session two, class members then burn sugar in a spoon to observe how it changes into carbon. Consider using real metal spoons rather than aluminum foil to avoid burning of the foil along with the sugar. These activities are part of an outstanding unit about global atmospheric change.
