Rise to the Point: Ice-Nucleating Protein in Water

CSEF · 2002 Chemistry

Lupita Guerrero, Melinda Mendoza · Anderson Valley Junior/Senior High School, Boonville

Overview

Objectives/Goals Ice-nucleating protein is a protein used as a snow inducer. Our project was to test this protein to see how much it raises the freezing point of water. Methods/Materials We used a container and added ice, rock salt, and water to get the temperature to be -5?C. Then we mixed ice-nucleating protein with distilled water. We put 3 ml of distilled water in one test tube and 3 ml of the ice-nucleating protein water in another test tube. To get data we connected a Vernier LabPro to a computer and two sensors to the LabPro. The computer graphed the temperature of the two test tubes for 35 minutes. Results In two of our test the plain water froze at a higher temperature. In three of our tests the water with ice-nucleating protein froze at a higher temperature. Conclusions/Discussion We didn't find a specific difference of degrees in the two, but we learned that water with ice-nucleating protein always freezes faster than plain water.

Summary statement

Our project was to find out how ice-nucleating protein affects the freezing point of water.
