Science Fair ProjectThe Carbonation of Soda

Liquid

Luis Torres

Statement of the Problem

How does Temperature affect the Carbonation of Sodas?

Project Overview

It was very fun and interesting, yet nothing was done to the sodas because the amount of time was very

insufficient

Research Interesting

Surprising

Fun

A lot of work

Definitely worth trying

Variables

Independent variable: Temperature Dependent variable: Soda Cans

(Operational Definition): Whether the cans shape will change or not.

Constant variables: Types of sodas, type of freezer, and time

Control group: Normal room temperature  

Hypothesis

Extreme cold temperatures will cause the soda can to explode.  

Materials

List of Materials 15 of the Same full soda cans

An empty freezer A thermometer

A Data Table, or Graph, and a Journal to record Data

A Camera Tape Measure

 

Procedure

Procedures Gather all materials in the list above

Before doing anything, set the freezer to the maximum of temperature, and let the freezer calibrate for 24 Hours Record at what time you changed the freezer’s temperature to estimate the 24 Hours

Label five of the soda cans “Max. Temp.”, another group of five soda cans “Min. Temp.”, and the last group of five soda cans “Mid. Temp.” Then, take one picture of the three groups of soda cans

Place the thermometer in the freezer for a few seconds to see the temperature Record that number, in Fahrenheit’s, in your Journal

Record the circumference of the group Place that number in your Journal

Record at what time you placed the group in the freezer in your Journal Place the group in the freezer for five hours

Check the freezer after two and a half hours with the thermometer Observe and record any overall changes in your Journal After the five hours, take a picture of the After result

Then, remove the group out of the freezer Record and observe any changes of the circumference in your Journal

After that, reset the freezer to the minimum temperature Repeat step 3-16

Then, reset the freezer to the middle temperature Repeat steps 3-16

After all that is done, you will make a Table that will look something like this:   IV

Group1 Group 2 Group 3

  Max. Temp.

     

Min Temp.      

Mid Temp.              

Inside each empty cell, you will place the outcome of each group’s shape/ circumference

Photos

Data/Observations (Analyzes)

Conclusion

The project didn’t go so well. I needed more than five hours for the experiment to come pout as needed.

Possible Experimental Errors

A possible/ common error in this experiment might be timing and recording observations

Applications and Recommendations

I recommend using your time more wisely to get a better test records/times
