Here are some ideas for fire projects to get you brainstorming. Visual Experiments What chemicals burn in different colors?What substances can mask the colors of flames?How does diminishing oxygen affect the appearance of a flame? Material Experiments Which type of oil produces the least soot when it burns? You can collect soot (carbon black) by burning in a container and wiping it down between tests or by examining a filter paper (or coffee filter) placed in with the test oil.Does it matter what type of wax is used to make a candle?Can you construct candles using liquid oils or other fuels besides wax? Environmental Experiments Analyze whether burning trash is a good alternative to landfills.Examine the effects of flame retardant chemicals on growing plants or on animals, such as insects or aquarium fish.Which common materials (for example: paper, foam, cloth, vinyl) produce the worst smoke/air pollution when burned?Examine how controlled burning is used for forests and parks.Examine the effects of ash on soil composition.
