What's the Fastest Way to Cool a Soda?
Procedure 1. Do your background research so that you are knowledgeable about terms, concepts and questions above. 2.Prepare an ice-only bath by adding enough ice to a styro-foam cooler to completely cover three cans of soda. 3. Prepare an ice water bath by adding the same amount of ice to a second styro foam cooler then covering the ice with water. 4. Use the instant read thermometer to measure the starting temperatures of the freezer compartment, the refrigerator, the ice only bath, and the ice water-bath. You'll need to open the cans of soda to take the temperature of the liquid inside. To minimize evaporation, cover the opening with a wad of plastic wrap after taking the temperature. In each case make sure that the temperature has stabilize before recording the result. For example, it may take a minute or two before the ice water temperature reaches equilibrium when the water is first added to the ice. 5. Place the three cans of soda in each of the cooling devices to be tested, i.e. : The freezer compartment, the refrigerator, the ice only bath, the ice water bath 6.Note the starting time for each cooling device. 7.At regular intervals (e,g, every 5 minutes) quickly remove each set of cans from their cooling device and measure the temperature of the soda. Note the time and temperature reading, then quickly put the cans back in the cooling device. Tips: Minimize the amount of time that the refrigerator and the freezer doors are open. It is good idea to periodically re-check the temperature of the cooling devices. 8. The experiment is complete when the temperature reading of the soda stabilizes. 9. For each cooling device calculate the average temperature of the three soda cans for each time points. 10. Make a graph of the average temperature of the soda y-axis) vesus elapsed time (in minutes) since the beginning of the experiment. Use a different symbol and color for each cooling device.

CONCLUSION
Based on the data collected from my experiment, the fastest way to cool a soda is the ice-water bath because more cold molecules are in contact with the surface of the can that any other cooling methods. Heat is transferred through conduction and convention. This conclusion Is also supported by facts from previous experiments conducted in the pass. The only reason why I choose this project because I love soda.
