Summary:
Today was the second day of our graphing project. Students finished graphing the daily high temperature, the ocean temperature, sunset time, and Earth’s tilt. When finished, the relationship was clear. Sunset time, air temperature, and ocean temperature are all related (with some time delay). And Earth’s tilt has a negative correlation with sunlight and temperature. Those students who finished early set to work graphing arctic sea-ice levels and atmospheric CO₂ levels for extra credit. News flash, they’re related!
