Our experiment is that when you put the egg on top of the bottle with the lit strip piece of paper,the fire can't get any oxygen so it sucks the egg in the bottle to get some oxygen.

We would also like to thank the websites that we got the information from and the people who created our 8th grade science textbook. Last but not least, we would like to thank our science teacher, Mrs. Hong, for helping us with every bump in the road that we came across.

PURPOSE
We are doing this experiment to show our fellow peers what air pressure is. People often neglect the fact that air fills up most of our Earth. Air pressure is a gas that pushes down on everything on Earth’s surface. Because the force of gravity pulls down on the air, it has a weight. This weight of the air is known as air pressure or atmospheric pressure. With doing this experiment, we are showing how air pressure acts on objects on Earth’s surface and how important it is to know this.
Process Set the egg on the bottle, its diameter is too large for it to slip inside. "The pressure of the air inside and outside of the bottle is the same, so the only force that would cause the egg to enter the bottle is gravity. Gravity isn't sufficient to pull the egg inside the bottle."(Helmenstine, A. "Egg in a Bottle Demonstration". 2013 About.com Chemistry.) When the temperature inside the bottle changes, change the pressure of the air inside the bottle. If there is a constant volume of air and heat it, the pressure of the air increases. Cool the air, the pressure decreases. Lower the pressure inside the bottle enough, the air pressure outside the bottle will push the egg into the container.
It's easy to see how the pressure changes when the bottle is chilled, but why is the egg pushed into the bottle when heat is applied? When the burning paper is dropped into the bottle, the paper will burn until the oxygen is consumed." Combustion heats the air in the bottle, increasing the air pressure. The heated air pushes the egg out of the way, making it appear to jump on the mouth of the bottle. As the air cools, the egg settles down and seals the mouth of the bottle."(Helmenstine, A. "Egg in a Bottle Demonstration". 2013 About.com Chemistry) Now there is less air in the bottle than when started, so it exerts less pressure. "When the temperature inside and outside the bottle is the same, there is enough positive pressure outside the bottle to push the egg inside."(Helmenstine, A. "Egg in a Bottle Demonstration". 2013 About.com Chemistry.)
HISTORY
APPLICATION Where else could this air pressure idea be used?
CONCLUSION (hypothesis correct?, next steps)
We believe the only changes needed for the experiment is the measurements of the strips of paper. And, the timing of the egg before it is placed over the bottle's opening. Those are our only adjustments we think should be needed because, the procedure is pretty basic and is explained like that repeatedly.
REFLECTION
We already learned about endothermic reaction and exothermic reaction this year in 8th grade. In the standard 8.5c. The standard states,"Students know chemical reactions usually liberate heat or absorb heat." There are references in our notebook page 57 and textbook references in chapter 2.3,6.1,and,6.4. The research we did helped us understand the experiment better of what we were going to be doing.
Finally, to know who is bringing the materials for the experiment or else your going to have like a project gone wrong. Our experiment “Egg in a Bottle” can be improved by doing the experiment before the due date. Also, have the experiment more organized. For example, know who is bringing the materials. We could also let the paper burn for a few seconds more before the egg is put over the bottle. I believe the improvements in the experiment,"Egg in a Bottle" are the timing of dropping the egg in the bottle.
Analysis
For our project, we had to research our experiment. During this experiment, we have learned about many things. Such as, air pressure, combustion, and temperature. Our experiment has a lot to do with these three topics. While conducting this experiment, we saw exactly how each three of these topics fit in.
Air pressure is the weight of air. Air has a weight because the force of gravity pulls down on the air, thus giving it a weight. In our experiment, air pressure is used when the egg is blocking the hot air’s only exit and the cold air’s only entrance. The air pressure, from outside of the bottle, pushes down on the egg. That is why the egg gets pushed in.
Combustion is the burning of an object. Combustion is shown in our experiment when the piece of paper is lit by a lighter and thrown into the glass bottle. When it is in the glass bottle, it heats up the air inside.
Temperature is the degree of hotness or coldness. In our experiment, the air on the inside’s temperature is and the air on the outside of the bottle’s temperature is cool. After hard-boiling the egg, the egg is hot for a while and then cools down. The temperature changes from hot to warm.
After researching and conducting this experiment we learned about these three topics. Air pressure is the weight of air. Combustion is the burning of an object. Temperature is the degree of hotness or coldness. We are glad that we learned about these three topics through our experiment and we hope that we can continue to learn more.

Air pressure: the force exerted by air, whether compressed or unconfined, on any surface in contact with it.
