Making Visible the Path of the Sun

The sun rises in the east and sets in the west. This we know from personal observation. But have you ever thought about where the sun is in the sky at the same time each day?

You might think the sun would appear at the same place at the same time each day. This would be true if Earth had no tilt and its orbit were a perfect circle. But this is not the case.

Solar Cell Energy Nationwide

MY NASA DATA microsets are created using data from NASA Earth science satellite missions. A microset is a small amount of data extracted from a much larger data file. Data is available on the atmosphere, biosphere, cryosphere, ocean, and land surface. Data and related lessons can be used with existing curriculum to help students practice science inquiry and math or technology skills using real measurements of Earth system variables and processes. In this activity, students use NASA data to determine areas of the country that are most likely to produce solar energy by analyzing differences in incoming solar radiation graphs.
