Procedure
The independent variables for this experiment are the types of water solutions used. The dependent variable is the boiling temperature of the water which will be measured by a thermometer. The control group is the water. The constants are the Stove top and amount of water used in each solution the starting temperature of the water and the Pot.

1. Pour 2 cups of water in the pot add 1 tablespoon of sugar then stir it up until all sugar is dissolved. 2. Turn on the stove, set the stove to it’s highest setting, place the pot on and time it with a stopwatch. Record the time and temperature of the solution as soon as it begins to boil. Record the data on your table. 3. Rinse pot vigorously to remove impurities, and allow the stovetop to cool. 4. Pour 2 cups of water in the pot add 1 tablespoon of salt and stir. Repeat steps 2 and 3. 5. Pour 2 cups of water in the pot then add 1 tablespoon of water. Repeat step 2.

Observations
When boiling the water it was quite pure and clear. There was no smell to it0 when boiling the salt water it was cloudy and the bottom of the pot was coated with salt. When boiling the sugar water it was cloudy but no residue was left in the pot.

Conclusion
Based on the graphs water has the highest boiling point over both salt and sugar water. The sugar water took the most energy to begin to boil and the salt water took the least as the heat evaporated some of the salt, which was left coating the pan. I don’t think we changed the waters boiling point by adding a new substance but we did change how fast it would come to a boil by making it more or less dense.
