- 3.Between the two cups above, which is the better insulator, and how do you know?
- 4.Name two variables that must be held constant for a fair comparison between two insulating materials.
- 5.Design a fair test comparing two insulating materials at home. Describe what you would keep the same and what data you would collect.
