help on my science project?? i need help now
i have to do this 8th grade science project
im doing a question which diffrent kinds of fabric burns the fastest out of wool,silk, linen and polyester? is that a good question? i also need help on it.. wut i was going to do was lay out the fabric in myu drivway separtly then lite the first oen with a match and time it then the same with the other 3 do you think this is a good idea?? if not give me some other questions i can ask and do a report on

Want to answer more questions in the Relationships category?
Maybe give some free advice about: Work/School Relationships?
Your question in a good start but what is the purpose of your experiment? Scientits use experiments to prove theories, and find solutions. No one cares if silk burns faster than wool, what does prove?
You need to answer WHY one fabric burns faster than others, what fibers are they made of and how does that effect the rate that it burns. What are the safest fabrics to ware? You need a reason to do the experiment.
May I also suggest maybe burning the fabric in the kitchen sink on in the bath tub. Then you are at a close source of water. Just be careful!

Well you could do a better project, but for what you have now, go into the primary purpose for choosing frabric burning.
Say: For my science project I have decided to conduct a series of experiements on the igniton of various fabrics which are wool, silk, linen, and polyester. The reason for conducting this experiment is to observe how each fabric reacts to the fire and to see which fabric is less flamable or can with stand the fire long enough to possible be out. My hypothesis is (what ever you think it is).
I hope this helped you! Tell me if it did

That could work. Make sure you use a pretty big bit of fabric so that you get chance to time it. Make sure you use the same amount of each fabric and the same flame each time. It might be a good idea to have a friend help you. One of you could time and one of you could burn.

setting them on fire won't really prove much of anything, other than maybe which ones burn the closest to completion by looking at the ashes that remain.
Perhaps you should look at what temperature each one will spontaneously combust? That data should be readily available, too... then you can follow that up with some controlled experiements. Looking at which leaves the least amount of reside would also be good... here's what you do:
get some glass or metal containers that you can burn the stuff in...
get samples of the fabrics and get a weight of each piece you intend to burn.
get the weight of each container, too
put a piece of fabric in a container, and set it on fire in a controlled manner - do not use anything other than a match or lighter to start the fire... let it burn as much as it will on its own.
Once the container has cooled, weight the whole thing. Subtract the starting container weight from the new total weight to get the weight of the burnt fabric. Compare the burned weight with the starting fabric weight. Calculate the weight loss.
Make observations while the fabric burns - are there intense flames? Is there lots of smoke? It the smoke more white in color, or is it all black and sooty? Are the ashed fine or chunky? Did the fabric even burn, or did part of it melt instead? Take good notes of all these things... you WILL see significant difference given the fabrics you listed.
Also, I would add cotton to your list. Do not burn silk - probably too expensive. Maybe swap out linen for nylon or a cotton-polyester blend?
