Shaking+Can--Mike,+Alex,+Josh

Myth (brief description)

Research (write down the words and definitions you were responsible for finding as well as the questions and answers) Josh pressure:the exurtion of force on an object. liquid: like water milk or soda are all liquid gas:a substance possesing perfect molecular mobility solute:the object dissolved into solute Mike Boyle's law:the relationship between the pressure and volume of a gas, if the temperature is kept constant within a closed system solvent:is a liquid, solid, or gas that dissolves another solid, liquid, or gaseous solute, resulting in a solution that is soluble in a certain volume of solvent at a specified temperature. molecule:an electrically neutral group of two or more atoms held together by covalent chemical bonds. Kinetic Energy:the energy which it possesses due to its motion. CO2:a naturally occurring chemical compound composed of two oxygen atoms covalently bonded to a single carbon atom. carbonation:the process of dissolving carbon dioxide in water. ingredients for a can of soda:carbonated water, fructose, caffeine (some times), most of the time sugar, phosphoric acid, 250 empty calories 1)The difference between gas and liquid:A gas will have whatever volume it's container has. A liquid always has a volume based on its type and mass(amount). Gases are compressable, liquids usually aren't. Molecules of gas have more energy so they vibrate quicker than molecules of liquid. Because of this vibration, gas molecules spread out more than liquid molecules. 2)companies put co2 into soda for taste. 3)companies get co2 into soda by bubbling cold to a saturation level. 4)the co2 is released from the can and enters the atmosphere.
 * Charles's law**:an experimental gas law which describes how gases tend to expand when heated.

Small Scale Conclusion: we conclude that tapping on the top works at stopping the fizzing because, after tapping the can and opening, the pop fizzed but went back in the can and no soda was lost, I think this happened because when we shake the can, the little molecules go all crazy and when we tapped on the top of the can, it settled the molecules down a little bit, but enough to stop if from exploding.

Alex Carbonation-saturation with carbon dioxide, as in making soda water Carbon dioxide-a colorless, odorless, incombustible gas, CO2,present in the atmosphere and formed during respiration, usually obtained by coal, coke, and natural gas by combustion, from carbohydrates by fermentation, from the reaction of acid on limestone. Pressure-the exertion of force upon a surface by an object, fluid etc... in contact with it Kinetic energy-the energy of a body or a system with respect to the motion of the body or of the particles in the system.

Large Scale Procedure 1) Get Materials a) Soda b) Camera c) Graduated cylinder d) Cup e) Stopwatch f) data tables Variables : independent : how long the can is shaken. Dependant if the can will still explode constant who shakes and tapps the can

2) Shake soda for 1 minute(x3 3) Video tape the soda being shaken(x3 4) Tap on top of can for 30 seconds(x3 5) Open the can of soda(x3 6) Pour soda into graduated cylinder(x3 7) Pour from cylinder into cup(x3 8) Write data down(x3

Tapping On The can of soda helps stop explosion

Some People said tapping on the can would not stop the explosion, but some people said it would stop the explosion so we weren't sure if it would work or not.

--Where should we tap on the can of soda? --Independent Variable: Where we tap the can of pop Dependent Variable: How much left the can after opening --We think tapping on the can will stop the explosion --Soda, stopwatch, camera, graduated cylinder, beaker, notebook, pencil, solo cup (green) --Get Materials, shake soda for 30seconds, tap can on bottom for 30 seconds, open, measure soda, repeat (second time tap side, third time tap top) --Small Scale Conclusion: we conclude that tapping on the top works at stopping the fizzing because, after tapping the can and opening, the pop fizzed but went back in the can and no soda was lost, I think this happened because when we shake the can, the little molecules go all crazy and when we tapped on the top of the can, it settled the molecules down a little bit, but enough to stop if from exploding.

--Does tapping the can of soda stop exploding? -- I-Variable: how long the can is shaken De-variable: How much soda is left in the can after opening --We Think tapping on the can stops the explosion --Materials: Soda, Camera, Graduated cylinder, Cup, Stopwatch, data tables --2) Shake soda for 1 minute(x3 3) Video tape the soda being shaken(x3 4) Tap on top of can for 30 seconds(x3 5) Open the can of soda(x3 6) Pour soda into graduated cylinder(x3 7) Pour from cylinder into cup(x3 8) Write data down(x3

Large Scale Conclusion: We conclude that tapping on the top of the shaken soda can reduces the explosion but not all of it because our results are test 1; 350ml of soda after opening, Test 2; 352ml after opening, Test 3; 290ml of soda after opening, Control; 300ml of soda after opening. I know this because the data table shows the average for the tests is 323ml left after opening. We think this happened because when we tap on the can, the Carbon Dioxide and Carbonation's pressure level goes way up and releases when the can is opened, tapping on the can lowers the pressure because tapping on the can breaks some bubbles but not all of them.

Based on the results, We Think the myth is Plausible.
