What are some control variables in this experiment?
Question 4

Data Table
Question 5
5.
Do you think anything was getting into or out of either of our 2 cup systems as the liquid in them was cooling down?
Question 6
6.
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?
Question 7
7.
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?
