3. B IG Q UESTION My big question is if I put a homemade hamburger and a McDonalds hamburger which one will rot first. I am trying to prove that a McDonalds hamburger has something called food plastic, it will never rot with the food plastic, while my homemade burger will.

4. H YPOTHESIS My hypothesis is that the McDonalds hamburger will not rot, but the homemade one will. I prove my point because someone has done this experiment before and I have seen what the McDonalds burger has in it.

5. I NGREDIENTS You will need one McDonalds hamburger And one homemade hamburger

6. S TEP B Y S TEP I NSTRUCTIONS First, put the two burgers some place were no one will touch them. Each week check on them, the one that is rotting has better stuff in it.

7. I T W ORKED ! The happy meal did not go bad. The home made burger turned bad and grew mold, but the happy meal did not go bad. The McDonalds burger still smelled like it was fresh. The home made burger smelled stinky. This is a picture of what the two burgers looked like when I started the experiment

9. M Y H YPOTHESIS WAS CORRECT It turned out just the way I planned. Here is a picture of when I finished the experiment.
