Does the Species of Wood (Poplar, Oak, or Pine) Affect the Burn Rate? Mandeville Middle School January 19, 2011 Abstract I. Statement of Problem and Hypothesis: A. Problem: Do the types of wood (poplar, oak, or pine) affect the burn rate? B. Hypothesis: My hypothesis is that pine will burn the fastest because it is less dense. II. Methodology: A. Variables: Independent Variable: Types of wood (poplar, oak, and pine.) Dependent Variable: How fast the wood burns. Controlled Variables: Size of wood samples, tempter of fire, method of ignition, shape of wood samples. B. Materials: Lighter (torch) Wood such as (poplar, oak, pine) Stopwatch Water Chiminea C. Procedure: Buy wood such as (poplar, oak, pine) cut into identical shape/size. Use the lighter (torch) to burn the wood in the chiminea and time how long it burns. Do the process 9 times (3 trials for each piece of wood.) Make sure to put out the fire with the water. Collect data then place on board. D. Research: Topics researched included burn rates of wood and calculating mass and density of wood samples. III. Analysis of Data: I found out that in the first trial when I placed the different types of woods in the fire, poplar was the fastest. Second was oak then the pinewood came in last. Next, I found out that when I placed the poplar it was still first to finish burning, second was oak, last was the pinewood. Finally, I found out that in the third trial the three woods; poplar, oak, and pine still stayed in the same burning order. The average time for pinewood is 5 minutes, oaks average time is 4 minutes 2 seconds, and the average time for poplar is 2 minutes and 33 seconds. IV. Summary and Conclusion: I found out when burning three different types of wood: pine, oak and poplar that each burned at a different rate. The poplar to my
