With all our ideas on the table about heat and cold moving and how various features may affect the cups, we began thinking about how each feature might help the cup system keep the drink cold. So while students ran cold-cup tests themselves, Mrs. Brinza was running her own tests! We started the beginning of the week thinking about the data, discussing the trends we saw, looking for patterns.
We came to this agreement:
1. Extra layers assist with keeping things cold.
2. Lids do something to keep the containers cooler.
3. Metal outperformed plastic as a material.
4. Straws really did nothing (although they are super convenient for drinking).
All this analysis made us think about if these same cups would be good at keeping something warm. So we set up some investigations again, collected data and will be ready to compare the results next week!
