Aim: My aim last year was to find out which way was the best to make your can of soda as cold as possible in ten minutes.
Hypothesis: My hypothesis was that the freezer would be the best way to cool your soda.
Introduction: I know that this topic will be interesting because it takes a while to make something go cold.
Equipment & Method: 5-10 cans of soda, cold water, ice and a thermometer.
Step 1:Grab all your cans of soda and set them on a table.
Step 2:First put one of your cans into the freezer (or put it in whatever different way you are doing it)and leave it there for ten minutes.
Step 3:Grab your can out of the freezer and open it.
Step 4: Grab your thermometer at put it in the soda and leave it
there for a minute then record how cold it was.
Results: My hypothesis was wrong and the freezer wasn't the best.
Conclusion:My result was a surprise and it just show you that the common way isn't always the best.
