Mrs. Brinza loves her coffee hot or cold... But this summer, as she was drinking a cold, icy coffee, she became frustrated about something that happens over and over again: Her cold drink warmed up and tasted watery. It then got her thinking about the fancy cups she's seen at Target... Why does the manufacturer of the fancy cup claim it can keep a drink colder longer? How does this actually work? We began our unit thinking about this phenomenon... |
We set up an investigation in class today, using both cups, some cold water and ice, and recorded some data over time. We're beginning to think about all the parts in each cup system along with what our temperature data tell us. We're also thinking about explaining what's going on by developing our initial models. There's a lot of curiosity in the air for sure!
