OBJECTIVE
• Through collaboration and experimentation, students will discover whether there is a correlation between the boiling point of water and the elevation at which water is boiled, the room temperature where water is boiled, or the heating device used to boil water.
PROJECT PURPOSE
• What Happens When Water Boils?• As water boils, the water turns into steam.
First the water begins to form bubbles at the bottom of the beaker. Then the bubbles begin to rise and pop off the surface, evaporating into the air. Energy is used to transform the water from its liquid to its gaseous state. This is the BOILING POINT of water.
PROJECT PURPOSE
• What Factor Has the Greatest Effect on the Boiling Point?
• Data was recorded to determine if the volume of water, elevation, heating device, or room temperature has the greatest effect on the Boiling Point of water.
THE EXPERIMENT LOG
• Room Temperature: 22 degrees Celsius
• Elevation: 21 meters
• Amount of Water: 300 milliliters
• Heating Device: Bunsen Burner

CONCLUSION
• The purpose of this investigation was to determine which factor had the greatest effect on the boiling point of water.
• The major finding from this experiment was that elevation had the greatest effect.
• The hypothesis “If the room temperature increases, then the boiling point will occur faster,” was not supported by the data.
