The Flammability of House Hold Items
By Piper Larson and Gracie Bethards
We did this experiment to test the flammability of certain house hold materials and how long it takes for those materials to burn and what they look like when they burn.
The items with tighter binding will take longer to burn and the items with looser bindings will burn quicker.
There are over 2 million fires reported to fire departments each year in the United States. Fabrics such as wool and silk burn slowly and usually extinguish on there own. Fabrics such as cottons and linens burn much faster and create little smoke. The weave in materials effects its flammability due to fine threads with open weaves. Materials that burn faster often create more smoke and materials such as nylon that tend to melt and retreat from the fire make very little smoke.
Our controls are the following:

Lace
Cotton
Nylon
Denim
First we took the denim and put it in our fire proof container and lit one corner on fire. We timed how long it took to get the material completely disintegrated or until the fire extinguished itself and we recorded the times, we also recorded the fires characteristics and what the material looked like as it was burning. We repeated this with the nylon, lace, cotton and silk.
The End
Thank You!

Time to Burn

Characteristics

Denim 5 min; 31.10 sec Slowly burns
Creates a lot of smoke

Nylon 10.3 sec Does not catch fire
Only melts

Lace 51.53 sec Extinguished itself
Slowly burns

Cotton 6 min; 8sec Creates a lot of smoke
Burns fast
Large flames

Silk 1 min; 52.73 sec Quickly burns
Very small flames
Little smoke
The items such as denim burned the slowest and had the tightest weaving/binding. Items such as lace burned the fastest and had the loosest weaving/binding.
