PLZ ANSWER ASAP I am doing an investigation where I simply throw a piece of paper that has been lit on fire, into a glass bottle/jar, and then throwing a hard boiled egg in the jar. Asides the outcome, equations, or whatnot with all that Chemistry stuff, I want to know:

What is the constant and what is variable?

*Thank you to anybody whom can answer, but please, please, please, give me the right answers. These labs are worst the most of my grade and I already have a D- in Chemistry.
