Beginning the group discussion. 1  Remind the group they are in a first draft conference; the drafts won't be polished. 2  Explain that sentence level discussion should be minimized. 3  Review the assignment with the group, making sure that they all understand the goals.
Fire is the rapid oxidation of a material in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. Slower oxidative processes like rusting or digestion are not included by this definition.
Scientists define combustion (what we call burning) as a reaction between a fuel, such as natural gas, oil, or wood, with an oxidant compound, such as oxygen. Combustion creates both heat and light. We can easily feel the heat from combustion, and we can see the emitted light in the form of flames.
