Objectives/Goals In my experiment, I burned different kinds of wood with different densities and timed how long they burned. My hypothesis is that the denser the wood is the longer it will burn. My question is obviously "does the density of the wood affect how long it burns." With my results fire fighters and reporters will be able make very realistic guesses as too how long a forest fire will burn and the way that it will burn. Methods/Materials I used four different kinds of wood and I burned them four times each. Poplar, Red Oak, Pine, and Douglas Fur were the different species. I had one independent variable which was the density and two dependent variables, one primary and one secondary. The primary variable was the flame time and the secondary variable was the smoke time. The constants in my experiment were used to minimize the number of confounding variables. After all the densities were found, I soaked them in two fluid ounces of lighter fluid for three ...
