The purpose of this project, called ‘Burning Wood’, is to see which type of wood chars, and ignites the fastest. In this experiment, I tested four different types of wood, Maple, Douglas Fir, Pine, and Oak. Besides the time measurements, I calculated values such as the mass before and after charring, the density, and the rate of burning. I burnt all the wood pieces on a barbecue. In this experiment, Maple chars the fastest, then Red Oak, Douglas Fir and pine. In this experiment, the wood that ignited the fastest was the maple wood, with an average of 15 minutes and 9 seconds to ignite. The average time of pine to ignite was 21 minutes and 12 seconds. Oakwood took 16 minutes and 45 seconds to ignite on average, and Douglas Fir took 16 minutes and 35 seconds. After the ignition, the average time it took for maple to char was 1 minute and 9 seconds. Although pine ignited very late compared to the other woods, once it did ignite it only took 1 minute and 47 seconds to char. Red Oak and Douglas Fir took the longest to char. Red Oak took 3 minutes and 37 seconds after it ignited to char, and Douglas Fir took 3 minutes and 55 seconds. This information can be used to help prevent forest fires.
