Title
My awesome sandwich mold growth experiment

Broad Question
Does a cheeseburger from home spoil more then one from a brand named company like Macdonald's in a spoil like environment.

Specific Question
Does the quality of a cheeseburger affect the rate of which it spoils.

Hypothesis
Since that fast food products have preservative, I predict that the replica I make at home lacking that will be subdued to mold faster.

Graph of Hypothesis
1=normal 2=starting to mold 3= molding 4= molded 5= covered in mold



Independent Variable:
mold rate

Dependent Variable:
Food (sandwich ect.)

Variables That Need To Be Controlled:
temperature

Vocabulary List That Needs Explanation
Subdued def: caused,making under the circumstances

General Plan
For my experiment I will put 3 of about the same cheese burgers from 3 different sources (home, MacDonald’s Burger king) in 3 separate containers in a temperature controlled room. They will remain untouched for one month with pictures being taken each day. After one month I will review my photos and compare my results, then I will concur whether a sandwich from home molds faster or worse then one from a brand named company. My experiment will be carefully watch over the said period of time.

Potential Problems And Solutions
People could eat the molded food and become sick. My solution to this is that there will be carefully place notes around my experiment saying "do not eat"

Safety Or Environmental Concerns
M As far as safety goes my only concern is that someone might eat my experiment or they could be allergic to the ingredients, but I can fix that by leaving notes near my experiment and telling my family that my food is not edible and that they could be allergic to it.

Experimental Design
(add the correct headings from the experimental design page before beginning)

Background Research
I learned that because of preservatives in fast food the mold rate could hate slight non molding effect

Detailed Procedure
1.Buy the hamburgers from local Macdonald's, Burger king and A homemade one. 2.Before you leave them to mold make sure there not touching and out of the rapper(preferably in a temperature controlled space for the most precise results) 3.Have safe area to leave the hamburgers to sit and mold. 4.Monitor the progression's of mold over a months course 5.Record the data(optional)
