Science Fair Project EGG-IN-A-BOTTLE Laura Sessions, Period: 8| Mrs. McNees| Syracuse Junior High Statement of the Problem Can you get an egg in to a bottle without physically pushing it? Research • • • • • It showed me how to get the egg out of the bottle. It showed me safety procedures for the project. It gave me tips for the project. Specified materials not needed, but it made the project easier. Gave me examples of how to do it. • Citations • www.hometrainingtools.com/egg-in-a-bottle-project/a/1645 • www.chemistryabout.com/a/chemistrydemonstrations/a/eggi nabottle.htm Hypothesis If the pressure in the bottle decreases, then the egg will get sucked in because of the loss of oxygen. Procedure: Materials • Hard-boiled eggs • Wide-mouth glass drink bottle • Vegetable oil • Matches • Strips of paper Procedure: Steps • Boil and peel eggs • Cover the mouth of the clean drink jar with vegetable oil • Light the strips of paper on fire and put it in the jar • Quickly place the egg on top of the jar • Observe Variables • Constants: The eggs • Controlled variables: The egg over the mouth of the bottle with no matches on the inside • Independent (manipulated) variable: Level of oxygen and carbon dioxide in the bottle. • Dependent (measured) variable: Change of pressure, amount of matches, size of egg, size of the mouth of the bottle. Data/Observations The first time I tried the experiment, it didn’t work. I discovered it was because I didn’t put the egg on top of the bottle fast enough. But, the second time it worked for me. It took about five seconds before the egg started wobbling. Conclusion H- The loss of oxygen in the bottle, due to the paper burning, sucked the egg into the bottle without me physically pushing, so my hypothesis was supported. P- Because of the loss of oxygen, the egg was sucked into the bottle.
