Understanding the Differences in Smoke Colors - Exploring the Science behind Black, Grey, and White Smoke
Smoke color can vary based on what is being burned, the level of combustion, and various other factors. Black smoke often indicates incomplete combustion of heavy materials, while grey smoke signals the fire settling down. White smoke is common at the start of a fire or with lighter fuels. By studying these differences, we can gain insights into fire behavior and aid investigations.

Why is some smoke black while others grey or white ______________________________________ By Kadilo Cally-Ntete and Jessica Rajapandian Grade 6
Our hypothesis When things get burned differently, it would affect the colour of smoke.
What is smoke? Smoke is the visible vapor and gases given off by a burning substance, especially the gray, brown, or blackish mixture of gases and suspended carbon particles resulting from the combustion of wood, peat, coal, or other organic matter.
Black smoke Black smoke can be a sign that a man made material is burning tires, vehicles or a structure. It could also mean that some heavy fuels are not consumed fully. The darker the smoke, the more fierce the fire is.
Grey smoke Grey smoke is when the fire starts settling down and has little left to burn.
White smoke White smoke usually happens at the start of a fire. It could also mean light fuels such as grass and twigs are being burned.
Conclusion There are several factors that affect the color of the smoke. When things get burnt differently, their color is affected. It depends on the raw materials being burnt, fuel and also the stage of the fire. Hence our hypothesis is right.
How can this help society? This could help society by finding out what caused a fire to happen and for how long it has lasted for. It also helps in various investigations This can also
