The Impact of Moisture on Wood Burning Duration: A Chemistry Experiment

This science fair project investigates whether moisture affects the burn duration of wood. The hypothesis is that dry wood will burn longer than wet wood. In the experiment, six identical logs were used, with three logs being soaked in water. Using a stopwatch, the burn time of both wet and dry logs was measured. Results confirmed that dry wood burned five minutes longer than wet wood, demonstrating the significant impact of moisture on wood combustion. Recommendations include uniform log sizes and consistent water application for more accurate results.

  1. Science Fair Project Does moisture effect burn of wood? Chemistry Jimmy Moore

  2. Statement of the Problem Will moisture affect how long wood burns compared to dry wood?

  3. Project Overview I will take one log, chop it into six different logs, pour water on three of the six logs, and set them o

  4. Research • Research showed that dry wood burns longer thanwet wood • Water puts out fire • The larger the wood the longer it burns

  5. Variables • Independent variable: The one variable that you purposely change and test. • Dependent variable: The measure of change observed because of the independent variable. It is important to decide how you are going to measure the change. (Operational Definition) • Constant variables: These are the things that are kept the same throughout your experiments. • Control group: This is the group used to compare with the independent variable. State why the CG makes logical sense for the experiment by giving a reason for the selection.

  6. Hypothesis • Based on the research you have done, you will be writing an answer or solution – your best educated guess – to your question. Make sure you write down your hypothesis before you begin your experiment.

  7. Materials • Six pieces of a log • Half a liter of water • An area to burn in • Matches or lighter • Stopwatch • Fire starter

  8. Procedure • Cut wood to make smaller shape • Gather materials needed • Pour water on three of the pieces of wood • Pour rubbing alcohol on both for a fire starter • Put on fire resistant gloves • Start fire on one log • Start stopwatch • Repeat steps six and seven • Record average time

  9. Photos • No photos

  10. Data/Observations (Analyzes)

  11. Conclusion My conclusion shows that my hypothesis was correct. The dry wood did indeed burn a whole five minutes longer than the wet wood. The piece of wood burned longer with the dry wood than with the wet wood.

  12. Possible Experimental Errors • Some experimental errors could be that the area is different as the logs burn at different times. • If I don’t put the exact same amount of water on logs • The size of logs

  13. Applications and Recommendations • Pour the exact same amounts of water on each log. • Make the logs the exact same size • Make larger logs
