1. What Factors Affect Burning?
By: Ajejandro Quesada

2. Research
Combustibility
Flammability
Chemical Properties

3. Hypothesis
If I add gas to wood then, it will burn faster?

4. Independent and Dependent Variable
Independent Variable
Wood
Gas
Dependent Variable
Rate at which the wood burns

5. Controlled (3)
Type of wood
Type of gas
Rate

6. Materials and Procedures
Mango wood
Lighter
Pen an paper
Knife
Gas
Timer
Procedures
Cut six pieces of wood about 12 inches long each.
Soak 3 pieces of wood in gas
Burn the three pieces soaked in gas individually, record combustion time.
Burn the three pieces not soaked in gas, record combustion time.
Compare results

7. Data

8. Conclusion
In the end my hypothesis was correct, though the wood did not fully burn it did burn way faster.
The experiment was fun :D

9. Will gas ignite wood faster then plain wood?
By: Alejandro Quesada

10. Research
Flammability

11. Hypothesis
My hypothesis is if I add gas to wood it will ignite faster.

12. Independent and Dependent Variable
Independent Variable
Gas
Wood
Dependent Variable
The time it take the wood to ignite or catch fire.

13. Controlled (3)
The type of wood
The type of gas
Ignition of flam

14. Materials and Procedures
Timer
Gas
Wood
Gloves
IPod for video
Match
Procedures
First I put on my gloves.
Secondly I put gas on the wood.
Third of all I get a match and throw it one the gas or plain wood and see how long it takes to ignite.

15. Data

16. Conclusion
My hypothesis was correct if you add gas to wood it will ignite faster.

17. Will the amount of sticks and gas affect how long the fire lasts?
By: Alejandro Quesada

18. Research
Combustibility

19. Hypothesis
If I add more sticks with gas over the sticks will the fire go on longer.

20. Independent and Dependent Variable
Independent Variable
Gas
Wood
Dependent Variable
The time the fire takes to put it self out.

21. Controlled
The amount of wood
The amount of gas

22. Materials and Procedures
Timer
Gas
Sticks
gloves
Knife
Match
Procedures
First I cut 12 inch sticks.
Second I put the woods in gas.
Third I get a match and put the wood on fire and see the time it take for it to finish.

23. Data

24. Conclusion
My hypothesis was right, if I put more wood and more gas the fire will go on longer.

25. Thanks for watching.
