Thinking about the air's role around the cups, we revisted our investigation ideas chart to see what we thought we could do to figure out how heat, or hot/cold air could maybe play a role in warming up the cups that weren't in light.
We had an idea to change the air temperature around a cup, either making it really hot or really cold. We could do with a hair dryer or a heater, or in the case of giving a cup access to cold air, we could go outside. There were a few problems with our ideas.
1. The air warmed up by a hair dryer or a heater wouldn't be consistent and no matter where we'd do this in our houses, the room would be too big to "enclose" the air and we'd get big differences in air temperature around the cups.
2. It was a whopping 3 degrees Farenheit this morning here in Chicago, so while this would give us cold air around our cups, that's just too cold for us to do our investigation outside!
We we thought of another idea...to use water around the cups instead of air. It would be easier to contain in a container, and we could easily heat up and cool down water at our homes (either in the microwave or by adding ice)! We made some predictions to close out class before we run the investigation tomorrow!
