Do Now: Is the making of ice cream a chemical reaction? Why?

Create a data table: Needs to include time intervals—30 seconds, one minute, etc. Temperature readings

Ice Cream: Acquire appropriate amounts of the following: Two bags (1 quart, 1 gallon—will be reused) ½ or ¼ cup Milk and ½ or ¼ cup Half and Half 2 tablespoons Sugar ½ teaspoon Vanilla 2 cups Ice 2 tablespoons Rock Salt Toppings if available–do not add until the end!

Procedure: Take temperature at appropriate intervals! Be certain to record the data—you will need to graph it for the lab report! Share the thermometers and be CAREFUL! Eat your product after all experimentation is complete!

Do Now: Given what we already know about freezing point depressions, what number of degree depression should we have seen in the lab? Does your data support such a conclusion?

Ice Cream Lab Report Take your data from yesterday, or my data on the board, and write a lab report on our lab. Your report must have all sections listed on the board—and is due by FRIDAY! It does not need to be typed, just written neatly, it is your first lab grade of the 4th nine weeks!

Conclusion Paragraph(s): What did you see? Use a content-heavy explanation. Why do you think that the depression was larger than expected? What sources of error might have altered your data? Be certain to include the terms polarity, deionize, freezing point depression, and colligative properties.
