We came to an agreement that the features for keeping things cold are seemingly the same for keeping things cold. While we felt really good about what we think is happening, deepening our discussion we realized this:
1. We don't really understand how both hot and cold are moving. We've had some discussion regarding heat and cold as particles and others saying cold doesn't actually even exist. It got us even more confused.
2. We recognized that a hot substance cools down faster than a cold substance warms up, but again, we really don't understand why.
3. Even with the best of features (lid, metal, and many walls), we don't really get how the temperature can change over time. What exactly is "leaking out" or "coming in?"
4. If a cup has no holes in the walls, why are we depicting that something can go through it? Are the holes just really that microscopic that heat or cold can go through them?
We went back to the drawing board and are thinking that we need to do some more investigations, particularly with a feature that seems obvious at keeping a warm substance warm and a cold substance cold.
The lid.
