Data Table
Do you think anything was getting into or out of either of our 2 cup systems as the liquid in them was cooling down?
What are some other systems (besides a cup) in which you think adding or removing a cover would affect the amount of liquid in the system over time and/or affect the temperature of the liquid in that system?
If we could completely seal off the cup so that no matter could get in or out, do you think the temperature of the liquid inside would still change if the liquid were cold water? Hot water? Why?
What is matter and how is it measured?
What is the independent variable in this experiment? (the thing that changes)
What is the DEPENDENT variable in this experiment? (the thing that DEPENDS on the independent variable)

Were your predictions correct? Describe if they were correct or not using the words mass and matter somewhere in your description.
If a cup lost mass, where did that lost matter go? Is it gone forever?
